‘Major update’ of BP guidance for kidney disease; treat to 120 mm Hg

Tue, 05/03/2022 - 15:06

The new 2021 Kidney Disease: Improving Global Outcomes (KDIGO) clinical practice guideline for blood pressure management for adults with chronic kidney disease (CKD) who are not receiving dialysis advises treating to a target systolic blood pressure of less than 120 mm Hg, provided measurements are “standardized” and that blood pressure is “measured properly.”

This blood pressure target – largely based on evidence from the Systolic Blood Pressure Intervention Trial (SPRINT) – represents “a major update” from the 2012 KDIGO guideline, which advised clinicians to treat to a target blood pressure of less than or equal to 130/80 mm Hg for patients with albuminuria or less than or equal to 140/90 mm Hg for patients without albuminuria.

The new goal is also lower than the less than 130/80 mm Hg target in the 2017 American College of Cardiology/American Heart Association guideline.

In a study of the public health implications of the guideline, Kathryn Foti, PhD, and colleagues determined that 70% of U.S. adults with CKD would now be eligible for treatment to lower blood pressure, as opposed to 50% under the previous KDIGO guideline and 56% under the ACC/AHA guideline.

“This is a major update of an influential set of guidelines for chronic kidney disease patients” at a time when blood pressure control is worsening in the United States, Dr. Foti, a postdoctoral researcher in the department of epidemiology at Johns Hopkins Bloomberg School of Public Health, Baltimore, said in a statement from her institution.

The 2021 KDIGO blood pressure guideline and executive summary and the public health implications study are published online in Kidney International.
 

First, ‘take blood pressure well’

The cochair of the new KDIGO guidelines, Alfred K. Cheung, MD, from the University of Utah, Salt Lake City, said in an interview that the guideline has “two important points.”

First, “take that blood pressure well,” he said. “That has a lot to do with patient preparation rather than any fancy instrument,” he emphasized.

Second, the guideline proposes a systolic blood pressure target of less than 120 mm Hg for most people with CKD not receiving dialysis, except for children and kidney transplant recipients. This target is “contingent on ‘standardized’ blood pressure measurement.”

The document provides a checklist for obtaining a standardized blood pressure measurement, adapted from the 2017 ACC/AHA blood pressure guidelines. It starts with the patient relaxed and sitting on a chair for more than 5 minutes.

In contrast to this measurement, a “routine” or “casual” office blood pressure measurement could be off by plus or minus 10 mm Hg, Dr. Cheung noted.

In a typical scenario, he continued, a patient cannot find a place to park, rushes into the clinic, and has his or her blood pressure checked right away, which would provide a “totally unreliable” reading. Adding a “fudge factor” (correction factor) would not provide an accurate reading.

Clinicians “would not settle for a potassium measurement that is 5.0 mmol/L plus or minus a few decimal points” to guide treatment, he pointed out.
 

Second, target 120, properly measured

“The very first chapter of the guidelines is devoted to blood pressure measurement, because we recognize if we’re going to do 120 [mm Hg] – the emphasis is on 120 measured properly – so we try to drive that point home,” Tara I. Chang, MD, guideline second author and a coauthor of the public health implications study, pointed out in an interview.

“There are a lot of other things that we base clinical decisions on where we really require some degree of precision, and blood pressure is important enough that to us it’s kind of in the same boat,” said Dr. Chang, from Stanford (Calif.) University.

“In SPRINT, people were randomized to less than less than 120 vs. less than 140 (they weren’t randomized to <130),” she noted.

“The recommendation should be widely adopted in clinical practice,” the guideline authors write, “since accurate measurements will ensure that proper guidance is being applied to the management of BP, as it is to the management of other risk factors.”
 

Still need individual treatment

Nevertheless, patients still need individualized treatment, the document stresses. “Not every patient with CKD will be appropriate to target to less than 120,” Dr. Chang said. However, “we want people to at least consider less than 120,” she added, to avoid therapeutic inertia.

“If you take the blood pressure in a standardized manner – such as in the ACCORD trial and in the SPRINT trial – even patients over 75 years old, or people over 80 years old, they have very little side effects,” Dr. Cheung noted.

“In the overall cohort,” he continued, “they do not have a significant increase in serious adverse events, do not have adverse events of postural hypotension, syncope, bradycardia, injurious falls – so people are worried about it, but it’s not borne out by the data.

“That said, I have two cautions,” Dr. Cheung noted. “One. If you drop somebody’s blood pressure rapidly over a week, you may be more likely to get in trouble. If you drop the blood pressure gradually over several weeks, several months, you’re much less likely to get into trouble.”

“Two. If the patient is old, you know the patient has carotid stenosis and already has postural dizziness, you may not want to try on that patient – but just because the patient is old is not the reason not to target 120.”
 

ACE inhibitors and ARBs beneficial in albuminuria, underused

“How do you get to less than 120? The short answer is, use whatever medications you need to – there is no necessarily right cocktail,” Dr. Chang said.

“We’ve known that angiotensin-converting enzyme (ACE) inhibitors and ARBs [angiotensin II receptor blockers] are beneficial in patients with CKD and in particular those with heavier albuminuria,” she continued. “We’ve known this for over 20 years.”

Yet, the study identified underutilization – “a persistent gap, just like blood pressure control and awareness,” she noted. “We’re just not making much headway.

“We are not recommending ACE inhibitors or ARBs for all the patients,” Dr. Cheung clarified. “If you are diabetic and have heavy proteinuria, that’s when the use of ACE inhibitors and ARBs are most indicated.”
 

Public health implications

SPRINT showed that treating to a systolic blood pressure of less than 120 mm Hg vs. less than 140 mm Hg reduced the risk for cardiovascular disease by 25% and all-cause mortality by 27% for participants with and those without CKD, Dr. Foti and colleagues stress.

They aimed to estimate how the new guideline would affect (1) the number of U.S. patients with CKD who would be eligible for blood pressure lowering treatment, and (2) the proportion of those with albuminuria who would be eligible for an ACE inhibitor or an ARB.

The researchers analyzed data from 1,699 adults with CKD (estimated glomerular filtration rate, 15-59 mL/min/1.73 m2 or a urinary albumin-to-creatinine ratio of ≥30 mg/g) who participated in the 2015-2018 National Health and Nutrition Examination Survey.

Both the 2021 and 2012 KDIGO guidelines recommend that patients with albuminuria and blood pressure higher than the target value who are not kidney transplant recipients should be treated with an ACE inhibitor or an ARB.

On the basis of the new target, 78% of patients with CKD and albuminuria were eligible for ACE inhibitor/ARB treatment by the 2021 KDIGO guideline, compared with 71% by the 2012 KDIGO guideline. However, only 39% were taking one of these drugs.

These findings show that “with the new guideline and with the lower blood pressure target, you potentially have an even larger pool of people who have blood pressure that’s not under control, and a potential larger group of people who may benefit from ACE inhibitors and ARBs,” Dr. Chang said.

“Our paper is not the only one to show that we haven’t made a whole lot of progress,” she said, “and now that the bar has been lowered, there [have] to be some renewed efforts on controlling blood pressure, because we know that blood pressure control is such an important risk factor for cardiovascular outcomes.”

Vasodilatory medications found protective against rosacea

Vasodilators may have a protective effect against rosacea, results from a single-center retrospective cohort study showed.

Dr. Jennifer G. Powers

“Our initial hypothesis was that perhaps antihypertensive agents might be associated with worsening rosacea,” one of the study authors, Jennifer G. Powers, MD, associate professor of dermatology at the University of Iowa, Iowa City, said in an interview. “What we found was exactly the opposite – that in fact their presence in a medical chart correlated with lower rates of rosacea diagnoses, as defined by ICD 9/10 codes.”

According to the researchers, who published their findings in the Journal of the American Academy of Dermatology, cases of acute vasodilator-induced rosacea have been reported, but no long-term association has been established. “In fact, many widely used antihypertensive medications modulate peripheral vascular tone,” they wrote. “Therefore, chronic use in patients with hypertension may reduce damage to peripheral vessels, and thus decrease risk of rosacea.”

To determine the correlates between vasodilator use and risk of rosacea, Dr. Powers and colleagues identified 680 hypertensive patients being treated with vasodilators or a thiazide diuretic in whom rosacea developed within 5 years of initiating therapy between June 1, 2006, and April 31, 2019. Vasodilator therapies included angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), beta-blockers, and calcium channel blockers (CCBs). Patients on thiazide diuretics served as the control group. The researchers stratified the patients by age, gender, race, diabetes, chronic kidney disease, and coronary artery disease and calculated relative risk estimates comparing vasodilators with thiazides between strata.



Of the 680 patients, all but 40 were White; 127 were on thiazides, and the remaining 553 were on vasodilators. Overall, the researchers observed that use of vasodilators had a protective effect on the development of rosacea within 5 years, compared with thiazides (relative risk [RR], 0.56; P less than .0001). Specifically, the relative risk was 0.50 for ACE-inhibitors (P less than .0001); 0.69 for ARBs (P = .041); 0.55 for beta-blockers (P less than .0001); and 0.39 for CCBs (P less than .0001).

Dr. Powers and colleagues also observed significant inverse correlations in ACE-inhibitors, beta-blockers, and CCBs among White women aged 50 and older, but no significance was observed in non-White subgroups. The cohorts of patients with chronic kidney disease and coronary artery disease were too small for analysis.

“We were very surprised to find that many of the agents we think of as vasodilators might actually be beneficial for rosacea,” Dr. Powers said. “We would like to see these results reproduced in larger population studies. There are also potential questions about the mechanism at play. However, should these findings hold true, [it’s] all the more reason for our rosacea patients with hypertension to be managed well. They need not fear that those medications are worsening disease. Also, there might be new therapeutic options based on this data.”

The study received funding support from the National Center for Advancing Translational Sciences. The researchers reported having no financial disclosures.

One of Dr. Powers’ coauthors is her husband, Edward M. Powers, MD, a cardiology fellow at the University of Iowa. “We sometimes bounce ideas off one another and will talk about how systemic effects on the vasculature may impact skin disease,” she said, noting that they also published a report on statins and atopic dermatitis.

There are also potential questions about the mechanism at play. However, should these findings hold true, [it’s] all the more reason for our rosacea patients with hypertension to be managed well. They need not fear that those medications are worsening disease. Also, there might be new therapeutic options based on this data.”

The study received funding support from the National Center for Advancing Translational Sciences. The researchers reported having no financial disclosures.

One of Dr. Powers’ coauthors is her husband, Edward M. Powers, MD, a cardiology fellow at the University of Iowa. “We sometimes bounce ideas off one another and will talk about how systemic effects on the vasculature may impact skin disease,” she said, noting that they also published a report on statins and atopic dermatitis.

Vasodilators may have a protective effect against rosacea, results from a single-center retrospective cohort study showed.

“Our initial hypothesis was that perhaps antihypertensive agents might be associated with worsening rosacea,” one of the study authors, Jennifer G. Powers, MD, associate professor of dermatology at the University of Iowa, Iowa City, said in an interview. “What we found was exactly the opposite – that in fact their presence in a medical chart correlated with lower rates of rosacea diagnoses, as defined by ICD 9/10 codes.”

According to the researchers, who published their findings in the Journal of the American Academy of Dermatology, cases of acute vasodilator-induced rosacea have been reported, but no long-term association has been established. “In fact, many widely used antihypertensive medications modulate peripheral vascular tone,” they wrote. “Therefore, chronic use in patients with hypertension may reduce damage to peripheral vessels, and thus decrease risk of rosacea.”

To determine the correlates between vasodilator use and risk of rosacea, Dr. Powers and colleagues identified 680 hypertensive patients being treated with vasodilators or a thiazide diuretic in whom rosacea developed within 5 years of initiating therapy between June 1, 2006, and April 31, 2019. Vasodilator therapies included angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), beta-blockers, and calcium channel blockers (CCBs). Patients on thiazide diuretics served as the control group. The researchers stratified the patients by age, gender, race, diabetes, chronic kidney disease, and coronary artery disease and calculated relative risk estimates comparing vasodilators with thiazides between strata.



Of the 680 patients, all but 40 were White; 127 were on thiazides, and the remaining 553 were on vasodilators. Overall, the researchers observed that use of vasodilators had a protective effect on the development of rosacea within 5 years, compared with thiazides (relative risk [RR], 0.56; P less than .0001). Specifically, the relative risk was 0.50 for ACE-inhibitors (P less than .0001); 0.69 for ARBs (P = .041); 0.55 for beta-blockers (P less than .0001); and 0.39 for CCBs (P less than .0001).

Dr. Powers and colleagues also observed significant inverse correlations in ACE-inhibitors, beta-blockers, and CCBs among White women aged 50 and older, but no significance was observed in non-White subgroups. The cohorts of patients with chronic kidney disease and coronary artery disease were too small for analysis.

“We were very surprised to find that many of the agents we think of as vasodilators might actually be beneficial for rosacea,” Dr. Powers said. “We would like to see these results reproduced in larger population studies.

Heart failure redefined with new classifications, staging

Tue, 05/03/2022 - 15:06

The terminology and classification scheme for heart failure (HF) is changing in ways that experts hope will directly impact patient outcomes.

Dr. Biykem Bozkurt

In a new consensus statement, a multisociety group of experts proposed a new universal definition of heart failure and made substantial revisions to the way in which the disease is staged and classified.

The authors of the statement, led by writing committee chair and immediate past president of the Heart Failure Society of America Biykem Bozkurt, MD, PhD, hope their efforts will go far to improve standardization of terminology, but more importantly will facilitate better management of the disease in ways that keep pace with current knowledge and advances in the field.

“There is a great need for reframing and standardizing the terminology across societies and different stakeholders, and importantly for patients because a lot of the terminology we were using was understood by academicians, but were not being translated in important ways to ensure patients are being appropriately treated,” said Dr. Bozkurt, of Baylor College of Medicine, Houston.

The consensus statement was a group effort led by the HFSA, the Heart Failure Association of the European Society of Cardiology, and the Japanese Heart Failure Society, with endorsements from the Canadian Heart Failure Society, the Heart Failure Association of India, the Cardiac Society of Australia and New Zealand, and the Chinese Heart Failure Association.

The article was published March 1 in the Journal of Cardiac Failure and the European Journal of Heart Failure, authored by a writing committee of 38 individuals with domain expertise in HF, cardiomyopathy, and cardiovascular disease.

“This is a very thorough and very carefully written document that I think will be helpful for clinicians because they’ve tapped into important changes in the field that have occurred over the past 10 years and that now allow us to do more for patients than we could before,” Eugene Braunwald, MD, said in an interview.

Dr. Braunwald and Elliott M. Antman, MD, both from TIMI Study Group at Brigham and Women’s Hospital and Harvard Medical School in Boston, wrote an editorial that accompanied the European Journal of Heart Failure article.
 

A new universal definition

“[Heart failure] is a clinical syndrome with symptoms and or signs caused by a structural and/or functional cardiac abnormality and corroborated by elevated natriuretic peptide levels and/or objective evidence of pulmonary or systemic congestion.”

This proposed definition, said the authors, is designed to be contemporary and simple “but conceptually comprehensive, with near universal applicability, prognostic and therapeutic viability, and acceptable sensitivity and specificity.”

Both left and right HF qualifies under this definition, said the authors, but conditions that result in marked volume overload, such as chronic kidney disease, which may present with signs and symptoms of HF, do not.

“Although some of these patients may have concomitant HF, these patients have a primary abnormality that may require a specific treatment beyond that for HF,” said the consensus statement authors.

For his part, Douglas L. Mann, MD, is happy to see what he considers a more accurate and practical definition for heart failure.

Dr. Douglas L. Mann


“We’ve had some wacky definitions in heart failure that haven’t made sense for 30 years, the principal of which is the definition of heart failure that says it’s the inability of the heart to meet the metabolic demands of the body,” Dr. Mann, of Washington University, St. Louis, said in an interview.

“I think this description was developed thinking about people with end-stage heart failure, but it makes no sense in clinical practice. Does it make sense to say about someone with New York Heart Association class I heart failure that their heart can’t meet the metabolic demands of the body?” said Dr. Mann, who was not involved with the writing of the consensus statement.
 

 

 

Proposed revised stages of the HF continuum

Overall, minimal changes have been made to the HF stages, with tweaks intended to enhance understanding and address the evolving role of biomarkers.

The authors proposed an approach to staging of HF:

  • At-risk for HF (stage A), for patients at risk for HF but without current or prior symptoms or signs of HF and without structural or biomarkers evidence of heart disease.
  • Pre-HF (stage B), for patients without current or prior symptoms or signs of HF, but evidence of structural heart disease or abnormal cardiac function, or elevated natriuretic peptide levels.
  • HF (stage C), for patients with current or prior symptoms and/or signs of HF caused by a structural and/or functional cardiac abnormality.
  • Advanced HF (stage D), for patients with severe symptoms and/or signs of HF at rest, recurrent hospitalizations despite guideline-directed management and therapy (GDMT), refractory or intolerant to GDMT, requiring advanced therapies such as consideration for transplant, mechanical circulatory support, or palliative care.

Stages in the development and progression of heart failure

One notable change to the staging scheme is stage B, which the authors have reframed as “pre–heart failure.”

“Pre-cancer is a term widely understood and considered actionable and we wanted to tap into this successful messaging and embrace the pre–heart failure concept as something that is treatable and preventable,” said Dr. Bozkurt.

“We want patients and clinicians to understand that there are things we can do to prevent heart failure, strategies we didn’t have before, like SGLT2 inhibitors in patients with diabetes at risk for HF,” she added.

The revision also avoids the stigma of HF before the symptoms are manifest.

“Not calling it stage A and stage B heart failure you might say is semantics, but it’s important semantics,” said Dr. Braunwald. “When you’re talking to a patient or a relative and tell them they have stage A heart failure, it’s scares them unnecessarily. They don’t hear the stage A or B part, just the heart failure part.”
 

New classifications according to LVEF

And finally, in what some might consider the most obviously needed modification, the document proposes a new and revised classification of HF according to left ventricular ejection fraction (LVEF). Most agree on how to classify heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF), but although the middle range has long been understood to be a clinically relevant, it has no proper name or clear delineation.

“For standardization across practice guidelines, to recognize clinical trajectories in HF, and to facilitate the recognition of different heart failure entities in a sensitive and specific manner that can guide therapy, we want to formalize the heart failure categories according to ejection fraction,” said Dr. Bozkurt.

To this end, the authors propose the following four classifications of EF:

  • HF with reduced EF (HFrEF): LVEF of up to 40%.
  • HF with mildly reduced EF (HFmrEF): LVEF of 41-49%.
  • HF with preserved EF (HFpEF)HF with an LVEF of at least 50%.
  • HF with improved EF (HFimpEF): HF with a baseline LVEF of 40% or less, an increase of at least 10 points from baseline LVEF, and a second measurement of LVEF of greater than 40%.

HFmrEF is usually a transition period, noted Dr. Bozkurt. “Patients with HF in this range may represent a population whose EF is likely to change, either increase or decrease over time and it’s important to be cognizant of that trajectory. Understanding where your patient is headed is crucial for prognosis and optimization of guideline-directed treatment,” she said.
 

Improved, not recovered, HF

The last classification of heart failure with improved ejection fraction (HFimpEF) represents an important change to the current classification scheme.

“We want to clarify what terms to use but also which not to use. For example, we don’t want people to use recovered heart failure or heart failure in remission, partly because we don’t want the medication to be stopped. We don’t want to give the false message that there has been full recovery,” said Dr. Bozkurt.

As seen in the TRED-HF trial, guideline-directed medical therapy should be continued in patients with HF with improved EF regardless of whether it has improved to a normal range of above 50% in subsequent measurements.

“This is a distinct group of people, and for a while the guidelines were lumping them in with HFpEF, which I think is totally wrong,” said Dr. Mann.

“I think it’s very important that we emphasize heart failure as a continuum, rather than a one-way street of [inevitable] progression. Because we do see improvements in ejection fraction and we do see that we can prevent heart failure if we do the right things, and this should be reflected in the terminology we use,” he added.

Dr. Bozkurt stressed that HFimpEF only applies if the EF improves to above 40%. A move from an EF of 10%-20% would still see the patient classified as having HFrEF, but a patient whose EF improved from, say, 30% to 45% would be classified as HFimpEF.

“The reason for this, again, is because a transition from, say an EF of 10%-20% does not change therapy, but a move upward over 40% might, especially regarding decisions for device therapies, so the trajectory as well as the absolute EF is important,” she added.

“Particularly in the early stages, people are responsive to therapy and it’s possible in some cases to reverse heart failure, so I think this change helps us understand when that’s happened,” said Dr. Braunwald.
 

One step toward universality

“The implementation of this terminology and nomenclature into practice will require a variety of tactics,” said Dr. Bozkurt. “For example, the current ICD 10 codes need to incorporate the at-risk and pre–heart failure categories, as well as the mid-range EF, preserved, and improved EF classifications, because the treatment differs between those three domains.”

In terms of how these proposed changes will be worked into practice guidelines, Dr. Bozkurt declined to comment on this to avoid any perception of conflict of interest as she is the cochair of the American College of Cardiology/American Heart Association HF guideline writing committee.

Dr. Braunwald and Dr. Antman suggest it may be premature to call the new terminology and classifications “universal.” In an interview, Dr. Braunwald lamented the absence of the World Heart Federation, the ACC, and the AHA as active participants in this effort and suggested this paper is only the first step of a multistep process that requires input from many stakeholders.

“It’s important that these organizations be involved, not just to bless it, but to contribute their expertise to the process,” he said.

For his part, Dr. Mann hopes these changes will gain widespread acceptance and clinical traction. “The problem sometimes with guidelines is that they’re so data driven that you just can’t come out and say the obvious, so making a position statement is a good first step. And they got good international representation on this, so I think these changes will be accepted in the next heart failure guidelines.”

To encourage further discussion and acceptance, Robert J. Mentz, MD, and Anuradha Lala, MD, editor-in-chief and deputy editor of the Journal of Cardiac Failure, respectively, announced a series of multidisciplinary perspective pieces to be published in the journal monthly, starting in May with editorials from Dr. Clyde W Yancy, MD, MSc, and Carolyn S.P. Lam, MBBS, PhD, both of whom were authors of the consensus statement.

Dr. Bozkurt reports being a consultant for Abbott, Amgen, Baxter, Bristol Myers Squibb, Liva Nova Relypsa/Vifor Pharma, Respicardia, and being on the registry steering committee for Sanofi-Aventis. Dr. Braunwald reports research grant support through Brigham and Women’s Hospital from AstraZeneca, Daiichi Sankyo, Merck, and Novartis; and consulting for Amgen, Boehringer-Ingelheim/Lilly, Cardurion, MyoKardia, Novo Nordisk, and Verve. Dr. Mann has been a consultant to Novartis, is on the steering committee for the PARADISE trial, and is on the scientific advisory board for MyoKardia/Bristol Myers Squibb.

  • HF with preserved EF (HFpEF)HF with an LVEF of at least 50%.
  • HF with improved EF (HFimpEF): HF with a baseline LVEF of 40% or less, an increase of at least 10 points from baseline LVEF, and a second measurement of LVEF of greater than 40%.

HFmrEF is usually a transition period, noted Dr. Bozkurt. “Patients with HF in this range may represent a population whose EF is likely to change, either increase or decrease over time and it’s important to be cognizant of that trajectory. Understanding where your patient is headed is crucial for prognosis and optimization of guideline-directed treatment,” she said.
 

Improved, not recovered, HF

The last classification of heart failure with improved ejection fraction (HFimpEF) represents an important change to the current classification scheme.

“We want to clarify what terms to use but also which not to use. For example, we don’t want people to use recovered heart failure or heart failure in remission, partly because we don’t want the medication to be stopped. We don’t want to give the false message that there has been full recovery,” said Dr. Bozkurt.

As seen in the TRED-HF trial, guideline-directed medical therapy should be continued in patients with HF with improved EF regardless of whether it has improved to a normal range of above 50% in subsequent measurements.

“This is a distinct group of people, and for a while the guidelines were lumping them in with HFpEF, which I think is totally wrong,” said Dr. Mann.

“I think it’s very important that we emphasize heart failure as a continuum, rather than a one-way street of [inevitable] progression. Because we do see improvements in ejection fraction and we do see that we can prevent heart failure if we do the right things, and this should be reflected in the terminology we use,” he added.

Dr. Bozkurt stressed that HFimpEF only applies if the EF improves to above 40%. A move from an EF of 10%-20% would still see the patient classified as having HFrEF, but a patient whose EF improved from, say, 30% to 45% would be classified as HFimpEF.

“The reason for this, again, is because a transition from, say an EF of 10%-20% does not change therapy, but a move upward over 40% might, especially regarding decisions for device therapies, so the trajectory as well as the absolute EF is important,” she added.

“Particularly in the early stages, people are responsive to therapy and it’s possible in some cases to reverse heart failure, so I think this change helps us understand when that’s happened,” said Dr. Braunwald.
 

One step toward universality

“The implementation of this terminology and nomenclature into practice will require a variety of tactics,” said Dr. Bozkurt. “For example, the current ICD 10 codes need to incorporate the at-risk and pre–heart failure categories, as well as the mid-range EF, preserved, and improved EF classifications, because the treatment differs between those three domains.”

In terms of how these proposed changes will be worked into practice guidelines, Dr. Bozkurt declined to comment on this to avoid any perception of conflict of interest as she is the cochair of the American College of Cardiology/American Heart Association HF guideline writing committee.

Dr. Braunwald and Dr. Antman suggest it may be premature to call the new terminology and classifications “universal.” In an interview, Dr. Braunwald lamented the absence of the World Heart Federation, the ACC, and the AHA as active participants in this effort and suggested this paper is only the first step of a multistep process that requires input from many stakeholders.

“It’s important that these organizations be involved, not just to bless it, but to contribute their expertise to the process,” he said.

For his part, Dr. Mann hopes these changes will gain widespread acceptance and clinical traction. “The problem sometimes with guidelines is that they’re so data driven that you just can’t come out and say the obvious, so making a position statement is a good first step. And they got good international representation on this, so I think these changes will be accepted in the next heart failure guidelines.”

To encourage further discussion and acceptance, Robert J. Mentz, MD, and Anuradha Lala, MD, editor-in-chief and deputy editor of the Journal of Cardiac Failure, respectively, announced a series of multidisciplinary perspective pieces to be published in the journal monthly, starting in May with editorials from Dr. Clyde W Yancy, MD, MSc, and Carolyn S.P. Lam, MBBS, PhD, both of whom were authors of the consensus statement.

Dr. Bozkurt reports being a consultant for Abbott, Amgen, Baxter, Bristol Myers Squibb, Liva Nova Relypsa/Vifor Pharma, Respicardia, and being on the registry steering committee for Sanofi-Aventis. Dr. Braunwald reports research grant support through Brigham and Women’s Hospital from AstraZeneca, Daiichi Sankyo, Merck, and Novartis; and consulting for Amgen, Boehringer-Ingelheim/Lilly, Cardurion, MyoKardia, Novo Nordisk, and Verve. Dr. Mann has been a consultant to Novartis, is on the steering committee for the PARADISE trial, and is on the scientific advisory board for MyoKardia/Bristol Myers Squibb.

Ivabradine knocks down heart rate, symptoms in POTS

Article Type
Changed
Thu, 08/26/2021 - 15:50

The heart failure drug ivabradine (Corlanor) can provide relief from the elevated heart rate and often debilitating symptoms associated with postural orthostatic tachycardia syndrome (POTS), a new study suggests.

Ivabradine significantly lowered standing heart rate, compared with placebo (77.9 vs. 94.2 beats/min; P < .001). The typical surge in heart rate that occurs upon standing in these patients was also blunted, compared with baseline (13.0 vs. 21.4 beats/min; P = .001).

“There are really not a lot of great options for patients with POTS and, mechanistically, ivabradine just make sense because it’s a drug that lowers heart rate very selectively and doesn’t lower blood pressure,” lead study author Pam R. Taub, MD, told this news organization.

Surprisingly, the reduction in heart rate translated into improved physical (P = .008) and social (P = .021) functioning after just 1 month of ivabradine, without any other background POTS medications or a change in nonpharmacologic therapies, she said. “What’s really nice to see is when you tackle a really significant part of the disease, which is the elevated heart rate, just how much better they feel.”

POTS patients are mostly healthy, active young women, who after some inciting event – such as viral infection, trauma, or surgery – experience an increase in heart rate of at least 30 beats/min upon standing accompanied by a range of symptoms, including dizziness, palpitations, brain fog, and fatigue.
 

A COVID connection?

The study enrolled patients with hyperadrenergic POTS as the predominant subtype, but another group to keep in mind that might benefit is the post-COVID POTS patient, said Dr. Taub, from the University of California, San Diego.

“We’re seeing an incredible number of patients post COVID that meet the criteria for POTS, and a lot of these patients also have COVID fatigue,” she said. “So clinically, myself and many other cardiologists who understand ivabradine have been using it off-label for the COVID patients, as long as they meet the criteria. You don’t want to use it in every COVID patient, but if someone’s predominant complaint is that their heart rate is going up when they’re standing and they’re debilitated by it, this is a drug to consider.”

Anecdotal findings in patients with long-hauler COVID need to be translated into rigorous research protocols, but mechanistically, whether it’s POTS from COVID or from another type of infection – like Lyme disease or some other viral syndrome – it should work the same, Dr. Taub said. “POTS is POTS.”

There are no first-line drugs for POTS, and current class IIb recommendations include midodrine, which increases blood pressure and can make people feel awful, and fludrocortisone, which can cause a lot of weight gain and fluid retention, she observed. Other agents that lower heart rate, like beta-blockers, also lower blood pressure and can aggravate depression and fatigue.

Ivabradine regulates heart rate by specifically blocking the Ifunny channel of the sinoatrial node. It was approved in 2015 in the United States to reduce hospitalizations in patients with systolic heart failure, and it also has a second class IIb recommendation for inappropriate sinus tachycardia.

The present study, reported in the Feb. 23 issue of the Journal of the American College of Cardiology, is the first randomized clinical trial using ivabradine to treat POTS.

A total of 26 patients with POTS were started on ivabradine 5 mg or placebo twice daily for 1 month, then were crossed over to the other treatment for 1 month after a 1-week washout period. Six patients were started on a 2.5-mg twice-daily dose. Doses were adjusted during the study based on the patient’s heart rate response and tolerance. Patients had seven clinic visits in which norepinephrine (NE) levels were measured and head-up tilt testing conducted.

Four patients in the ivabradine arm withdrew because of adverse effects, and one withdrew during crossover.

Among the 22 patients who completed the study, exploratory analyses showed a strong trend for greater reduction in plasma NE upon standing with ivabradine (P = .056). The effect was also more profound in patients with very high baseline standing NE levels (at least 1,000 pg/mL) than in those with lower NE levels (600 to 1,000 pg/mL).

“It makes sense because that means their sympathetic nervous system is more overactive; they have a higher heart rate,” Dr. Taub said. “So it’s a potential clinical tool that people can use in their practice to determine, ‘okay, is this a patient I should be considering ivabradine on?’ ”

Although the present study had only 22 patients, “it should definitely be looked at as a step forward, both in terms of ivabradine specifically and in terms of setting the standard for the types of studies we want to see in our patients,” Satish R. Raj, MD, MSCI, University of Calgary (Alta.), said in an interview.

In a related editorial, however, Dr. Raj and coauthor Robert S. Sheldon, MD, PhD, also from the University of Calgary, point out that the standing heart rate in the placebo phase was only 94 beats/min, “suggesting that these patients may be affected only mildly by their POTS.”

Asked about the point, Dr. Taub said: “I don’t know if I agree with that.” She noted that the diagnosis of POTS was confirmed by tilt-table testing and NE levels and that patients’ symptoms vary from day to day. “The standard deviation was plus or minus 16.8, so there’s variability.”

Both Dr. Raj and Dr. Taub said they expect the results will be included in the next scientific statement for POTS, but in the meantime, it may be a struggle to get the drug covered by insurance.  

“The challenge is that this is a very off-label use for this medication, and the medication’s not cheap,” Dr. Raj observed. The price for 60 tablets, which is about a 1-month supply, is $485 on GoodRx.

Another question going forward, he said, is whether ivabradine is superior to beta-blockers, which will be studied in a 20-patient crossover trial sponsored by the University of Calgary that is about to launch. The primary completion date is set for 2024.

The study was supported by a grant from Amgen. Dr. Taub has served as a consultant for Amgen, Bayer, Esperion, Boehringer Ingelheim, Novo Nordisk, and Sanofi; is a shareholder in Epirium Bio; and has received research grants from the National Institutes of Health, the American Heart Association, and the Department of Homeland Security/FEMA. Dr. Raj has received a research grant from the Canadian Institutes of Health Research and research grants from Dysautonomia International to address the pathophysiology of POTS. Dr. Sheldon has received a research grant from Dysautonomia International for a clinical trial assessing ivabradine and propranolol for the treatment of POTS.

Outcomes have improved for PAH in connective tissue disease

Article Type
Changed
Thu, 02/18/2021 - 14:39

Survival rates for patients with pulmonary arterial hypertension associated with connective tissue diseases have improved significantly in recent years, and there is growing evidence that treatments for idiopathic pulmonary arterial hypertension can also benefit this group.

Dr. Dinesh Khanna

In an article published online Feb. 3, 2021, in Arthritis & Rheumatology, researchers report the outcomes of a meta-analysis to explore the effect of more modern pulmonary arterial hypertension treatments on patients with conditions such as systemic sclerosis.

First author Dinesh Khanna, MBBS, MSc, of the division of rheumatology at the University of Michigan, Ann Arbor, said in an interview that connective tissue disease–associated pulmonary arterial hypertension (CTD-PAH) was a leading cause of death, but earlier clinical trials had found poor outcomes in patients with CTD, compared with those with idiopathic PAH.

“Recent clinical trial data show that aggressive, up-front PAH treatments have better outcomes in those with CTD-PAH, and we wanted to explore these observations carefully in a systematic review and meta-analysis,” Dr. Khanna said.

The analysis included 11 randomized, controlled trials, involving 4,329 patients with PAH (1,267 with CTD), and 19 registries with a total of 9,739 patients with PAH, including 4,008 with CTD. Trials were required to report long-term clinical outcomes with a median enrollment time of greater than 6 months, and outcomes measured between 3-6 months after the patients started treatment.

Patients with CTDs had an older mean age and a lower 6-minute walk distance than did those with idiopathic PAH.

Five randomized, controlled trials – involving 3,172 patients, 941 of whom had a CTD – found that additional PAH treatment was associated with a 36% reduction in the risk of morbidity or mortality events, compared with controls both in the overall PAH group and in those with CTD.

Additional therapy was also associated with a 34.6-meter increase in 6-minute walk distance in the general PAH population, and a 20.4-meter increase in those with CTD.

The authors commented that the smaller improvement in 6-minute walk distance among patients with CTD may be influenced by comorbidities such as musculoskeletal involvement that would be independent of their cardiopulmonary function.
 

Differential patient survival among PAH etiologies

“Our meta-analysis of RCTs demonstrated that patients with CTD-PAH derive a clinically significant benefit from currently available PAH therapies which, in many patients, comprised the addition of a drug targeting a second or third pathway involved in the pathophysiology of PAH,” the authors wrote.

When researchers analyzed data from nine registries that included a wide range of PAH etiologies, they found the overall survival rates were lower among patients with CTD, compared with the overall population. The analysis also suggested that patients with systemic sclerosis and PAH had lower survival rates than did those with systemic lupus erythematosus.

Dr. Khanna said this may relate to different pathophysiology of PAH in patients with CTDs, but could also be a reflection of other differences, such as older age and the involvement of other comorbidities, including lung fibrosis and heart involvement.

Data across all 19 registries also showed that survival rates among those with CTD were higher in registries where more than 50% of the registry study period was during or after 2010, compared with registries where 50% or more of the study period was before 2010.



The authors suggested the differences in survival rates may relate to increased screening for PAH, particularly among people with CTDs. They noted that increased screening leads to earlier diagnosis, which could introduce a lead-time bias such that later registries would have younger participants with less severe disease. However, their analysis found that the later registries had older patients but also with less severe disease, and they suggested that it wasn’t possible to determine if lead-time bias was playing a role in their results.

Improvements in treatment options could also account for differences in survival over time, although the authors commented that only six registries in the study included patients from 2015 or later, when currently available treatments came into use and early combination therapy was used more.

“These data also support the 2018 World Symposium on Pulmonary Hypertension recommendations to initiate up-front combination pulmonary arterial hypertension therapy in majority of cases with CTD-PAH,” Dr. Khanna said.

 

 

‘Still have to be aggressive at identifying the high-risk patients’

Commenting on the findings, Virginia Steen, MD, of the division of rheumatology at Georgetown University, Washington, said clinicians were finally seeing some significant changes over time in scleroderma-associated PAH.

Dr. Virginia Steen

“Although some of it may be just early diagnosis, I think that the combination of early diagnosis and more aggressive treatment with combination medication is definitely making a difference,” Dr. Steen said in an interview. “The bottom line is that we as rheumatologists still have to be aggressive at identifying the high-risk patients, making an early diagnosis, and working with our pulmonary hypertension colleagues and aggressively treating these patients so we can make a long-term difference.”

The authors of an accompanying editorial said the meta-analysis’ findings showed the positive impact of early combination therapy and early diagnosis through proactive screening.

“It is notable because the present analysis again confirms that outcomes are worse in CTD-PAH than in idiopathic or familial forms of PAH, the impact of treatments should no longer be regarded as insignificant,” the editorial’s authors wrote. “This is a practice changing observation, especially now that many of the drugs are available in generic formulations and so the cost of modern PAH treatment has fallen at the same time as its true value is convincingly demonstrated.”

They also argued there was strong evidence for the value of combination therapies, both for PAH-targeted drugs used in combination and concurrent use of immunosuppression and drugs specifically for PAH in some patients with CTD-PAH.

However, they pointed out that not all treatments for idiopathic PAH were suitable for patients with CTDs, highlighting the example of anticoagulation that can improve survival in the first but worsen it in the second.

The study was funded by Actelion. Six authors declared funding and grants from the pharmaceutical sector, including the study sponsor, and three authors were employees of Actelion.

First author Dinesh Khanna, MBBS, MSc, of the division of rheumatology at the University of Michigan, Ann Arbor, said in an interview that connective tissue disease–associated pulmonary arterial hypertension (CTD-PAH) was a leading cause of death, but earlier clinical trials had found poor outcomes in patients with CTD, compared with those with idiopathic PAH.

“Recent clinical trial data show that aggressive, up-front PAH treatments have better outcomes in those with CTD-PAH, and we wanted to explore these observations carefully in a systematic review and meta-analysis,” Dr. Khanna said.

The analysis included 11 randomized, controlled trials, involving 4,329 patients with PAH (1,267 with CTD), and 19 registries with a total of 9,739 patients with PAH, including 4,008 with CTD. Trials were required to report long-term clinical outcomes with a median enrollment time of greater than 6 months, and outcomes measured between 3-6 months after the patients started treatment.

Patients with CTDs had an older mean age and a lower 6-minute walk distance than did those with idiopathic PAH.

Five randomized, controlled trials – involving 3,172 patients, 941 of whom had a CTD – found that additional PAH treatment was associated with a 36% reduction in the risk of morbidity or mortality events, compared with controls both in the overall PAH group and in those with CTD.

Additional therapy was also associated with a 34.6-meter increase in 6-minute walk distance in the general PAH population, and a 20.4-meter increase in those with CTD.

The authors commented that the smaller improvement in 6-minute walk distance among patients with CTD may be influenced by comorbidities such as musculoskeletal involvement that would be independent of their cardiopulmonary function.
 

Differential patient survival among PAH etiologies

“Our meta-analysis of RCTs demonstrated that patients with CTD-PAH derive a clinically significant benefit from currently available PAH therapies which, in many patients, comprised the addition of a drug targeting a second or third pathway involved in the pathophysiology of PAH,” the authors wrote.

When researchers analyzed data from nine registries that included a wide range of PAH etiologies, they found the overall survival rates were lower among patients with CTD, compared with the overall population. The analysis also suggested that patients with systemic sclerosis and PAH had lower survival rates than did those with systemic lupus erythematosus.

Dr. Khanna said this may relate to different pathophysiology of PAH in patients with CTDs, but could also be a reflection of other differences, such as older age and the involvement of other comorbidities, including lung fibrosis and heart involvement.

Data across all 19 registries also showed that survival rates among those with CTD were higher in registries where more than 50% of the registry study period was during or after 2010, compared with registries where 50% or more of the study period was before 2010.



The authors suggested the differences in survival rates may relate to increased screening for PAH, particularly among people with CTDs. They noted that increased screening leads to earlier diagnosis, which could introduce a lead-time bias such that later registries would have younger participants with less severe disease. However, their analysis found that the later registries had older patients but also with less severe disease, and they suggested that it wasn’t possible to determine if lead-time bias was playing a role in their results.

Improvements in treatment options could also account for differences in survival over time, although the authors commented that only six registries in the study included patients from 2015 or later, when currently available treatments came into use and early combination therapy was used more.

“These data also support the 2018 World Symposium on Pulmonary Hypertension recommendations to initiate up-front combination pulmonary arterial hypertension therapy in majority of cases with CTD-PAH,” Dr. Khanna said.

 

 

‘Still have to be aggressive at identifying the high-risk patients’

Commenting on the findings, Virginia Steen, MD, of the division of rheumatology at Georgetown University, Washington, said clinicians were finally seeing some significant changes over time in scleroderma-associated PAH.

“Although some of it may be just early diagnosis, I think that the combination of early diagnosis and more aggressive treatment with combination medication is definitely making a difference,” Dr. Steen said in an interview. “The bottom line is that we as rheumatologists still have to be aggressive at identifying the high-risk patients, making an early diagnosis, and working with our pulmonary hypertension colleagues and aggressively treating these patients so we can make a long-term difference.”

The authors of an accompanying editorial said the meta-analysis’ findings showed the positive impact of early combination therapy and early diagnosis through proactive screening.

“It is notable because the present analysis again confirms that outcomes are worse in CTD-PAH than in idiopathic or familial forms of PAH, the impact of treatments should no longer be regarded as insignificant,” the editorial’s authors wrote. “This is a practice changing observation, especially now that many of the drugs are available in generic formulations and so the cost of modern PAH treatment has fallen at the same time as its true value is convincingly demonstrated.”

They also argued there was strong evidence for the value of combination therapies, both for PAH-targeted drugs used in combination and concurrent use of immunosuppression and drugs specifically for PAH in some patients with CTD-PAH.

However, they pointed out that not all treatments for idiopathic PAH were suitable for patients with CTDs, highlighting the example of anticoagulation that can improve survival in the first but worsen it in the second.

The study was funded by Actelion. Six authors declared funding and grants from the pharmaceutical sector, including the study sponsor, and three authors were employees of Actelion.

Survival rates for patients with pulmonary arterial hypertension associated with connective tissue diseases have improved significantly in recent years, and there is growing evidence that treatments for idiopathic pulmonary arterial hypertension can also benefit this group.

Menopause transition affects heart health risks

Article Type

Menopause is a key time to monitor women for the development or increase of cardiovascular risk factors, according to a new consensus statement developed by the Task Force on Gender of the European Society of Cardiology and a multidisciplinary ESC working group on Women’s Health in Menopause.

“After menopause, traditional cardiovascular risk factors are adversely affected – particularly hypertension,” wrote Angela H.E.M. Maas, MD, of Radboud University Medical Center, Nijmegen, Netherlands, and colleagues.

“Since the first ESC consensus paper on the management of cardiovascular risk in perimenopausal women was published in 2007, we have a greater understanding on the role of female-specific risk factors for cardiovascular disease (CVD),” they said.

In a consensus statement published in the European Heart Journal, the authors presented clinical guidance for diagnosis and management of cardiovascular risk factors during the menopause transition. The transition to menopause increases a woman’s risk for developing several CVD risk factors, including central adiposity, increased insulin resistance, a proatherogenic lipid profile, and autonomic dysfunction that can contribute to increased heart rate variability, according to the statement.

Estrogen changes may affect ischemic disease

In general, obstructive coronary artery disease (CAD) strikes women later than men, but coronary vasomotor conditions are a common cause of ischemic heart disease in women with or without CAD, the authors noted.

“Lower estrogen levels after menopause are related to altered vascular function, enhanced inflammation, and up-regulation of other hormonal systems such as the renin–angiotensin–aldosterone system, the sympathetic nervous system, and reduced nitric oxide–dependent vasodilation,” they wrote. They recommended use of the coronary artery calcium score for screening middle-aged women who are symptomatic or at intermediate cardiovascular risk.

The transition to menopause causes changes in lipid profiles, and a rise in blood pressure in particular “may be both a direct effect of hormonal changes on the vasculature and metabolic changes with aging,” but hypertension in early post menopause is “often poorly managed,” the authors noted.

Compared with asymptomatic women, women who suffer from severe menopausal symptoms often have increased cardiovascular disease risk factors. For example, the Women’s Health Initiative (WHI) study showed a 48% increased risk of incident diabetes at follow-up in women with severe symptoms of hot flashes and night sweats, the authors wrote. Clinicians should also be aware of the increased immune reactivity that occurs during and after menopause and the increased CVD risk associated with autoimmune and endocrine disorders, they said.
 

Multiple strategies to reduce risk

Strategies to address the cardiovascular risk in menopause include assessing glucose, lipid levels, and blood pressure during the transition to menopause, according to the statement.

In addition, they recommended increasing employer awareness of menopause, as changes may interfere with working ability. A healthy lifestyle including healthy diet and regular exercise can help reduce cardiovascular risks and relieve symptoms. Menopausal hormone therapy (MHT) may be indicated to relieve symptoms, including symptoms of depression, and provide cardioprotection for younger women around the time of menopause, according to the statement.

However, “MHT is not recommended in women at high CV risk and after a previous CVD event,” and all women should be assessed for cardiovascular risk factors before starting MHT, they emphasized.
 

 

 

Results raise awareness of cardiovascular health and menopause link

“Over the past 20 years, our knowledge of how menopause might contribute to cardiovascular disease has dramatically evolved,” said Samar El Khoudary, MD, of the University of Pittsburg, in an interview.

“We have accumulated data that consistently point to the menopause transition as a time of change in cardiovascular health. As such, there is a compelling need to discuss the implications of the accumulating body of literature on this topic,” she said. “The goal is to raise awareness for both health care providers and women of the significant adverse cardiovascular health changes accompanying the menopause transition and to point out the importance of adopting prevention strategies early during this stage,” she explained.

The impact of the hormonal changes of menopause on CVD risk “is very complex,” Dr. El Khoudary said. “Until now, we could not prove that using estrogen therapy is cardioprotective,” she emphasized. “Studies point to the need to consider the timing of hormone use, as well as types and route of administration,” she noted. “The truth is that, although the menopause transition is associated with an acceleration in CVD risk, the exact mechanism still is not completely clear. Hormone changes contribute, but they are not the ultimate contributor,” she added.

 

Research gaps include data on lifestyle and behavioral interventions

“Irrespective of the accumulating findings showing adverse changes in multiple cardiovascular health parameters, as women transition through menopause, we do not have data documenting current status of ideal cardiovascular health components during the menopause transition among women,” said Dr. El Khoudary. “The limited data we have [suggest] that a very small proportion of women transitioning through menopause eat a healthy diet (less than 20%) or practice physical activity (about7.2%) at a level that matches the current recommendations,” she noted.

“Lifestyle and behavioral interventions are critical to maintain a healthy heart and reduce heart disease; we do not have adequate randomized clinical trials testing these interventions specifically during the menopause transition,” she said.

“Similarly, we are in need of randomized clinical trials of therapeutic interventions such as lipid-lowering medications and menopause hormone therapy in women transitioning through menopause,” said Dr. El Khoudary. “This high-risk population has not been the focus of previous clinical trials, leaving us with questions of how the results from these studies might apply to women during the menopause transition,” she said.
 

Consensus invites collaboration

“I commend the group for putting together a statement that crosses practice and specialty boundaries,” said Lubna Pal, MD, of Yale School of Medicine, New Haven, Conn., in an interview. Although the statement does not present novel information, it “has the power of unifying the various providers by bringing focus on the individual elements spanning a woman’s life that cumulatively determine her lifetime health risk,” she said. Preeclampsia may be a risk factor for cardiovascular disease later in life, and events in reproductive age may determine a woman’s trajectory during the transition to menopause and beyond, Dr. Pal noted.

“The consensus statement will likely be read by internists and family medicine providers as well as ob.gyns.; it encourages all those involved in caring for female patients to take on the responsibility of ‘passing on the baton,’ such that all women who are deemed at an enhanced risk for cardiovascular disease are assured due diligence in care through stringent surveillance and timely interventions,” said Dr. Pal. “It is a call for the various providers who care for women at distinct stages of life to work together toward a shared goal of optimizing every woman’s health across her lifespan,” she said.

“More research is needed for us to better understand the mechanisms at play” in the development of cardiovascular risk and in understanding the continuity of changes across women’s lifespans, Dr. Pal said. “We have associations, but not much information about causation,” she emphasized. However, the statement promotes the dissemination of information about women’s health and sensitizes providers to the potential and the power of preventive care. “We should be much more liberal and loud in holding conversations about risk quantification and risk reduction, and this statement is a resounding effort toward identifying and mitigating long-term cardiovascular risk, even if only through promoting a healthier lifestyle in those deemed at risk,” she added.  

The statement received no outside funding. Lead author Dr. Maas had no financial conflicts to disclose. Dr. El Khoudary had no financial conflicts to disclose. Dr. Pal had no relevant financial conflicts to disclose.

Metformin tied to longer gestation in women with preterm preeclampsia

Metformin extended gestation by nearly a week in women with preterm preeclampsia and was also linked to a shorter neonatal hospital stay, according to findings from a study presented Jan. 28 at the virtual Society for Maternal-Fetal Medicine 2021 Annual Pregnancy Meeting.

The causes of preeclampsia have continued to elude researchers, but most agree the placenta plays a key role, explained Cathy Cluver, PhD, director of the preeclampsia research unit and an associate professor at Stellenbosch University, Cape Town. Past trials have tested sildenafil, antithrombin, pravastatin, and esomeprazole, but the drugs either did not show promise, had unacceptable side effects, or need further study.

“This trial provides proof of concept that preterm preeclampsia can be treated and that we can slow the progression of preterm preeclampsia,” Dr. Cluver said.

In this trial, the researchers enrolled 180 women with preterm preeclampsia between 26 and 31 weeks of gestation. All the women were taking hypertensives. They were randomly assigned to receive 3 g oral metformin XR or placebo daily. The intention-to-treat analysis included 87 women who received metformin and 84 who received placebo, with baseline characteristics similar in both groups.

Women in the metformin group gave birth a median 16.2 days after randomization, which was 6.7 days longer than the 9.5 days postrandomization delivery of women in the placebo group. The differences, however, narrowly missed statistical significance (P =.056).

But when the researchers took compliance and dose into account, the effect of the metformin increased, showing a dose-dependent effect, and did reach statistical significance. Among the 147 women who continued treatment until delivery, those in the metformin group delivered a median 8.4 days later than those in the placebo group (16.2 vs. 7.4 days; P =.026). Further, when the analysis was further restricted to just the 100 women who continued taking the full dose until delivery, the difference was even greater (16.2 vs. 4.8 days; P =.008). In accordance with the safety profile of metformin, women taking the drug had more diarrhea and a trend toward more nausea than those taking the placebo.

There were no differences between the groups in composite maternal or neonatal outcomes, but the infants were an average 136 g (4.8 ounces) heavier in the metformin group, albeit the difference did not reach statistical significance. The 6-day–shorter neonatal stay at the study site facility for infants of the metformin group also did not reach statistical significance, but there was a significant difference between the groups on overall stay, including transfers to other facilities. Infants in the metformin group averaged 26 days vs. 34 days for infants in the placebo group (P =.007).

“We have shown that metformin XR may be a treatment for preterm preeclampsia. We now plan to do a larger study to hopefully confirm these findings, which will be powered to both prolongation of pregnancy and neonatal outcomes,” Dr. Cluver told this news organization. “We have also shown that one can prolong pregnancy in preterm preeclampsia, and we hope that this will encourage others in our field to continue researching therapeutics for preterm preeclampsia.”

In response to questions from attendees, Dr. Cluver reported that her team did not collect histological data from placentas in this study, and lack of funding is limiting their ability to evaluate longer-term outcomes.

The findings of prolonged gestation were certainly exciting, but they warrant caution before any changes in clinical practice, Michelle Y. Owens, MD, professor and chief of maternal-fetal medicine at the University of Mississippi Medical Center, Jackson, said in an interview.

“While the findings of this study are promising, the sample size was small, the dosing exceeds what we typically use in the U.S., and this was undertaken in Cape Town, South Africa, all of which may render this study less generalizable to our population and others across the globe,” said Dr. Owens, who moderated the oral abstract session.

She also pointed out a possible conflicting effect on birth weight brought on by using metformin to extend gestation.

“If larger studies are undertaken, I believe it is quite possible that, with extended gestation, there will be bigger babies,” she said. “However, metformin also helps control blood glucose and in so doing, may contribute to lower birth weights over time, compared with women not exposed to the drug.”

Dr. Cluver and Dr. Owens have disclosed no relevant financial relationships.

Metformin extended gestation by nearly a week in women with preterm preeclampsia and was also linked to a shorter neonatal hospital stay, according to findings from a study presented Jan. 28 at the virtual Society for Maternal-Fetal Medicine 2021 Annual Pregnancy Meeting.

The causes of preeclampsia have continued to elude researchers, but most agree the placenta plays a key role, explained Cathy Cluver, PhD, director of the preeclampsia research unit and an associate professor at Stellenbosch University, Cape Town. Past trials have tested sildenafil, antithrombin, pravastatin, and esomeprazole, but the drugs either did not show promise, had unacceptable side effects, or need further study.

Study flags cardiovascular disease in men with breast cancer

Article Type
Changed
Wed, 01/04/2023 - 16:41

Cardiovascular disease and related risk factors can be common among male breast cancer patients, suggests a small study in this rare malignancy.

Among 24 male breast cancer patients evaluated over a decade in the Washington area, 88% were obese or overweight, 58% had hypertension, and 54% had hyperlipidemia.

Tachyarrhythmia existed in 8% of the men before cancer treatment and developed in 13% during treatment.

Two patients had preexisting heart failure, two patients developed the disease after treatment, and another two patients experienced a decline in left ventricular ejection fraction during the course of their cancer treatment.

“Our hope is that treating male breast cancer patients becomes a multidisciplinary approach where oncologists recruit their cardio-oncologist counterparts to mitigate cardiovascular risk factors, so patients live a long and healthy life after cancer treatment,” said Michael Ibrahim, one of the study authors and a 4th-year medical student at Georgetown University in Washington.

The data were presented Jan. 25 as part of the American College of Cardiology’s Advancing the Cardiovascular Care of the Oncology Patient virtual course, which is hosting live sessions Feb. 5-6.

Although the association between cardiovascular disease and breast cancer is well documented in female breast cancer patients, there is little evidence in their male counterparts, especially African Americans, Mr. Ibrahim noted.

To provide some context, Mr. Ibrahim highlighted a 2018 report in nearly 3,500 female breast cancer patients, ages 40-79, in whom 52% were obese/overweight, 35% had hypertension, and 28% had hyperlipidemia.

Diabetes was present in 7.5% of the women, which was roughly equivalent to the 8% found among the men, Mr. Ibrahim said. The men were of similar age (38-79 years), with 42% being African American, 29% White, 4% Hispanic, and 25% another ethnicity.

Importantly, half of the men had a family history of breast cancer, and two were positive for a mutation in the BRCA gene.

2017 in-depth review of male breast cancer cites advancing age, hormonal imbalance, radiation exposure, and family history of breast cancer as key risk factors for the development of the disease, but the “most relevant risk factor” is a mutation in the BRCA2 gene.

Male breast cancer accounts for less than 1% of all breast cancers, but the incidence is rising and, in some patient groups, reaching 15% over their lifetimes, the paper notes. Additionally, these patients are at special risk for developing a second cancer.

Remarkably, 25% of men in the D.C. cohort were diagnosed with a second primary malignancy, 13% a third primary cancer, and 4% a fourth primary cancer, Mr. Ibrahim reported. “This goes to show that male breast cancer patients should routinely undergo cancer screening,” he said.

The initial diagnosis was invasive ductal carcinoma in 79% of the men, with the remaining ductal carcinoma in situ. All patients underwent mastectomy, 17% had anthracycline chemotherapy, 8% received HER2-targeted therapy, 16% had radiation, and 71% received hormone therapy.

In terms of cardiovascular management, statins were the most prescribed medication (46%), followed by antiplatelet therapy (42%) and angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (38%).

An implantable cardioverter defibrillator/pacemaker was the most common intervention (16%), followed by bypass surgery in 8% and coronary angioplasty in 4%.

Mr. Ibrahim noted that the study was limited by the small sample size and that further research is needed to understand the risk of preexisting cardiovascular disease on long-term outcomes as well as the cardiotoxic effects of chemoradiation in male breast cancer patients.

In a statement, Mr. Ibrahim reiterated the need for a multidisciplinary cancer care team to evaluate patients’ cardiovascular risk prior to and through cancer treatment.

“On a more personal level, cancer patients are already surprised by their cancer diagnosis,” he added. “Similar to the pretreatment consultation with radiation oncology, breast surgery, and medical oncology, an upfront cardiovascular risk assessment provides greater comfort and further minimizes psychological surprise with cardiovascular complications going into cancer treatment.”

The authors have disclosed no relevant financial relationships.

Algorithm trims time to treatment of acute hypertension in pregnancy

Article Type
Changed
Tue, 02/02/2021 - 12:56

Use of a semiautonomous algorithm to initiate treatment for hypertension emergencies in pregnancy significantly increased the number of individuals treated promptly, based on data from 959 obstetric patients.

Data show poor compliance with the current American College of Obstetricians and Gynecologists recommendations for treatment of acute severe hypertension with no more than 30-60 minutes’ delay; low compliance may be caused by “multiple factors including lack of intravenous access, inadequate health care practitioner or nursing availability, and implicit racial biases,” wrote Courtney Martin, DO, of Loma Linda (Calif.) University School of Medicine and colleagues.

Semiautomated treatment algorithms have been used to improve timely treatment of conditions including myocardial infarction, heart failure, acute stroke, and asthma, but their use in obstetrics to date has been limited, the researchers noted.

In a retrospective cohort study published in Obstetrics & Gynecology, the researchers identified pregnant and postpartum women treated for severe hypertension at a single center between January 2017 and March 2020. A semiautonomous treatment algorithm was implemented between May 2018 and March 2019. The algorithm included vital sign monitoring, blood pressure thresholds for diagnosis of severe hypertension, and automated order sets for recommended first-line antihypertensive therapy. The primary outcomes were treatment with antihypertensive therapy within 15, 30, and 60 minutes of diagnosis. “Severe hypertension was defined as systolic blood pressure 160 mm Hg or higher or diastolic blood pressure 110 mm Hg or higher,” the researchers said.

The study population was divided into three groups; a preimplementation group (373 patients) managed between January 2017 and April 2018, a during-implementation group (334 patients) managed between May 2018 and March 2019, and a postimplementation group (252 patients) managed between April 2019 and March 2020. Patient demographics were similar among all three groups.
 

Timely treatment improves with algorithm

Overall, treatment of severe hypertension within 15 minutes of diagnosis was 36.5% preimplementation, 45.8% during implementation, and 55.6% postimplementation. Severe hypertension treatment within 30 minutes of diagnosis was 65.9% preimplementation, 77.8% during implementation, and 79.0% post implementation. Differences were significant between pre- and post implementation for 15 minutes and 30 minutes, but no significant differences occurred in the patients treated within 60 minutes before and after implementation of the algorithm.

The study findings were limited by several factors, including the inability to separate peer-to-peer education and other training from the impact of the algorithm, as well as a lack of data on the effect of the algorithm on maternal or neonatal outcomes, the researchers noted.

However, the results support the potential of a semiautonomous algorithm to significantly improve adherence to the recommended treatment guidelines for severe hypertension in pregnancy and post partum, they said. Given the expected increase in hypertensive disorders in pregnancy because of the trends in older age and higher obesity rates in pregnant women, “Integration of semiautonomous treatment algorithms similar to ours into routine obstetric practices could help reduce the health care burden and improve clinical outcomes, especially in areas with limited health care resources,” they concluded.
 

Algorithm may reduce disparities

The overall rise in maternal mortality in the United States remains a concern, but “Even more concerning are the disturbing racial disparities that persist across socioeconomic strata,” wrote Alisse Hauspurg, MD, of the University of Pittsburgh in an accompanying editorial. “There is clear evidence that expeditious treatment of obstetric hypertensive emergency reduces the risk of severe morbidities including stroke, eclampsia, and maternal death,” she emphasized, but compliance with the ACOG recommendations to treat severe hypertension within 30-60 minutes of confirmation remains low, she said.

In this study, not only did use of the algorithm reduce time to antihypertensive therapy, but more than 50% of patients were treated for severe hypertension within 15 minutes, and more than 90% within 60 minutes, “which was sustained after the implementation phase,” and aligns with the ACOG recommendations, Dr. Hauspurg said. “Although Martin et al.’s algorithm was limited to the initial management of obstetric hypertensive emergency, it could readily be expanded to follow the full ACOG algorithm for management of hypertension in pregnancy,” she noted.

In addition, Black women are more frequently diagnosed with hypertensive disorders of pregnancy, including severe hypertension, and the algorithm might improve disparities, she said.

“It is plausible that widespread implementation of such a semiautonomous algorithm at hospitals across the country could reduce delays in treatment and prevent hypertension-related morbidities,” said Dr. Hauspurg. “The use of innovative approaches to management of severe hypertension and other obstetric emergencies has the potential to allow provision of more equitable care by overcoming health care practitioner and system biases, which could meaningfully reduce disparities in care and change the trajectory of maternal morbidity and mortality in the United States,” she emphasized.
 

Need to create culture of safety

“Maternal mortality in the United States is the highest among developed nations, and shocking disparities exist in outcomes for non-Hispanic Black and American Indian/Alaskan Native women,” said Lisa Hollier, MD, of Texas Children’s Health Plan in Bellaire. “In a California review of maternal deaths, the greatest quality improvement opportunities were missed diagnosis and ineffective treatment of preeclampsia and related diseases, which occurred in 65% of the cases where women died of preeclampsia/eclampsia,” she said.

The current study “is very timely as more and more states across the nation are participating in the AIM (Alliance for Innovation on Maternal Health) programs to prevent pregnancy-related mortality,” Dr. Hollier noted.

“This study demonstrated a significant association between implementation of the algorithm and an increased percentage of treatment of severe hypertension within 30 minutes,” Dr. Hollier said. “With the implementation of a comprehensive program that included treatment algorithms, the Illinois Perinatal Quality Collaborative improved timely treatment for women with severe high blood pressure, increasing the percentage of patients treated within 60 minutes from 41% at baseline to 79% in the first year of the project.”

The take-home message is that “implementation of the semiautonomous treatment algorithm can address important clinical variation, including delays in appropriate treatment of severe hypertension,” said Dr. Hollier. However, “One of the potential barriers [to use of an algorithm] is the need for accurate, real-time clinical assessment. Resources must be available to ensure appropriate monitoring,” Dr. Hollier noted. “Collaboration and support of implementation of these treatment algorithms must extend through the nursing staff, the physicians, and advanced-practice providers. Medical staff and administrative leaders are essential in creating a culture of safety and continuous process improvement,” she said.

In addition, “long-term follow-up on the implementation of broader quality improvement programs is essential,” Dr. Hollier said. “While implementation of an algorithm can, and did, result in process improvements, assessment of broader implementation of evidence-based bundles, combined with a systematic approach to redesign of multiple related processes needs to occur and include outcomes of severe maternal morbidity and mortality,” she explained.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Neither Dr. Hauspurg nor Dr. Hollier had financial conflicts to disclose.

In a retrospective cohort study published in Obstetrics & Gynecology, the researchers identified pregnant and postpartum women treated for severe hypertension at a single center between January 2017 and March 2020. A semiautonomous treatment algorithm was implemented between May 2018 and March 2019. The algorithm included vital sign monitoring, blood pressure thresholds for diagnosis of severe hypertension, and automated order sets for recommended first-line antihypertensive therapy. The primary outcomes were treatment with antihypertensive therapy within 15, 30, and 60 minutes of diagnosis. “Severe hypertension was defined as systolic blood pressure 160 mm Hg or higher or diastolic blood pressure 110 mm Hg or higher,” the researchers said.

The study population was divided into three groups; a preimplementation group (373 patients) managed between January 2017 and April 2018, a during-implementation group (334 patients) managed between May 2018 and March 2019, and a postimplementation group (252 patients) managed between April 2019 and March 2020. Patient demographics were similar among all three groups.
 

Timely treatment improves with algorithm

Overall, treatment of severe hypertension within 15 minutes of diagnosis was 36.5% preimplementation, 45.8% during implementation, and 55.6% postimplementation. Severe hypertension treatment within 30 minutes of diagnosis was 65.9% preimplementation, 77.8% during implementation, and 79.0% post implementation. Differences were significant between pre- and post implementation for 15 minutes and 30 minutes, but no significant differences occurred in the patients treated within 60 minutes before and after implementation of the algorithm.

The study findings were limited by several factors, including the inability to separate peer-to-peer education and other training from the impact of the algorithm, as well as a lack of data on the effect of the algorithm on maternal or neonatal outcomes, the researchers noted.

However, the results support the potential of a semiautonomous algorithm to significantly improve adherence to the recommended treatment guidelines for severe hypertension in pregnancy and post partum, they said. Given the expected increase in hypertensive disorders in pregnancy because of the trends in older age and higher obesity rates in pregnant women, “Integration of semiautonomous treatment algorithms similar to ours into routine obstetric practices could help reduce the health care burden and improve clinical outcomes, especially in areas with limited health care resources,” they concluded.
 

Algorithm may reduce disparities

The overall rise in maternal mortality in the United States remains a concern, but “Even more concerning are the disturbing racial disparities that persist across socioeconomic strata,” wrote Alisse Hauspurg, MD, of the University of Pittsburgh in an accompanying editorial. “There is clear evidence that expeditious treatment of obstetric hypertensive emergency reduces the risk of severe morbidities including stroke, eclampsia, and maternal death,” she emphasized, but compliance with the ACOG recommendations to treat severe hypertension within 30-60 minutes of confirmation remains low, she said.

In this study, not only did use of the algorithm reduce time to antihypertensive therapy, but more than 50% of patients were treated for severe hypertension within 15 minutes, and more than 90% within 60 minutes, “which was sustained after the implementation phase,” and aligns with the ACOG recommendations, Dr. Hauspurg said. “Although Martin et al.’s algorithm was limited to the initial management of obstetric hypertensive emergency, it could readily be expanded to follow the full ACOG algorithm for management of hypertension in pregnancy,” she noted.

In addition, Black women are more frequently diagnosed with hypertensive disorders of pregnancy, including severe hypertension, and the algorithm might improve disparities, she said.

“It is plausible that widespread implementation of such a semiautonomous algorithm at hospitals across the country could reduce delays in treatment and prevent hypertension-related morbidities,” said Dr. Hauspurg. “The use of innovative approaches to management of severe hypertension and other obstetric emergencies has the potential to allow provision of more equitable care by overcoming health care practitioner and system biases, which could meaningfully reduce disparities in care and change the trajectory of maternal morbidity and mortality in the United States,” she emphasized.
 

Need to create culture of safety

“Maternal mortality in the United States is the highest among developed nations, and shocking disparities exist in outcomes for non-Hispanic Black and American Indian/Alaskan Native women,” said Lisa Hollier, MD, of Texas Children’s Health Plan in Bellaire. “In a California review of maternal deaths, the greatest quality improvement opportunities were missed diagnosis and ineffective treatment of preeclampsia and related diseases, which occurred in 65% of the cases where women died of preeclampsia/eclampsia,” she said.

The current study “is very timely as more and more states across the nation are participating in the AIM (Alliance for Innovation on Maternal Health) programs to prevent pregnancy-related mortality,” Dr. Hollier noted.

“This study demonstrated a significant association between implementation of the algorithm and an increased percentage of treatment of severe hypertension within 30 minutes,” Dr. Hollier said. “With the implementation of a comprehensive program that included treatment algorithms, the Illinois Perinatal Quality Collaborative improved timely treatment for women with severe high blood pressure, increasing the percentage of patients treated within 60 minutes from 41% at baseline to 79% in the first year of the project.”

The take-home message is that “implementation of the semiautonomous treatment algorithm can address important clinical variation, including delays in appropriate treatment of severe hypertension,” said Dr. Hollier. However, “One of the potential barriers [to use of an algorithm] is the need for accurate, real-time clinical assessment. Resources must be available to ensure appropriate monitoring,” Dr. Hollier noted. “Collaboration and support of implementation of these treatment algorithms must extend through the nursing staff, the physicians, and advanced-practice providers. Medical staff and administrative leaders are essential in creating a culture of safety and continuous process improvement,” she said.

In addition, “long-term follow-up on the implementation of broader quality improvement programs is essential,” Dr. Hollier said. “While implementation of an algorithm can, and did, result in process improvements, assessment of broader implementation of evidence-based bundles, combined with a systematic approach to redesign of multiple related processes needs to occur and include outcomes of severe maternal morbidity and mortality,” she explained.

The study received no outside funding. The researchers had no financial conflicts to disclose.

Neither Dr. Hauspurg nor Dr. Hollier had financial conflicts to disclose.

Use of a semiautonomous algorithm to initiate treatment for hypertension emergencies in pregnancy significantly increased the number of individuals treated promptly, based on data from 959 obstetric patients.

Data show poor compliance with the current American College of Obstetricians and Gynecologists recommendations for treatment of acute severe hypertension with no more than 30-60 minutes’ delay; low compliance may be caused by “multiple factors including lack of intravenous access, inadequate health care practitioner or nursing availability, and implicit racial biases,” wrote Courtney Martin, DO, of Loma Linda (Calif.) University School of Medicine and colleagues.

Semiautomated treatment algorithms have been used to improve timely treatment of conditions including myocardial infarction, heart failure, acute stroke, and asthma, but their use in obstetrics to date has been limited, the researchers noted.

Large study weighs in on ‘fat but fit’ paradox

Physical activity mitigated the impact of high body mass index (BMI) on cardiovascular risk factors, but not overall cardiovascular disease risk, according to an observational study of half a million individuals.

Dr. Prakash Deedwania

Despite the historically high rates of overweight and obesity worldwide, some evidence suggests that cardiorespiratory fitness could reduce the effects of excess weight on cardiovascular disease risk, wrote Pedro L. Valenzuela, PhD, of the University of Alcalá, Madrid, and colleagues.

“To clarify the existence of the ‘fat-but-fit’ [or ‘elevated BMI but active’] paradox, in this observational study, we assessed the joint association between different BMI categories and physical activity levels, respectively, and the prevalence of major CVD risk factors,” they said.

In a population-based cohort study published in the European Journal of Preventive Cardiology, the researchers identified 527,662 adults aged 18-64 years who were insured by an occupational risk–prevention company and underwent annual medical exams as part of their coverage. The average age of the participants was 42 years, 32% were women, and the average BMI was 26.2 kg/m2.

The participants were categorized as normal weight (42%), overweight (41%), and obese (18%), and their activity levels were categorized as inactive (64%), insufficiently active (12%), and regularly active (24%). In addition, 30% had hypercholesterolemia, 15% had hypertension, and 3% had diabetes.

Overall, compared with inactivity, insufficient activity or regular activity reduced CVD risk factors within each BMI category, and subgroups. “However, regular/insufficient PA did not compensate for the negative effects of overweight/obesity, as individuals with overweight/obesity were at greater CVD risk than their peers with normal weight, irrespective of PA levels,” the researchers said. Compared with active normal-weight men, the odds ratios for hypertension in active overweight men and active obese men were 1.98 and 4.93, respectively; the odds ratios for hypercholesterolemia were 1.61 and 2.03, respectively, and the odds ratios for diabetes were 1.33 and 3.62, respectively (P < .001 for all). Trends were similar for women.

The study results were limited by the cross-sectional design; inability to control for participants’ diet, and the reliance of self-reports of leisure-time physical activity. However, the findings were strengthened by the large sample size and “refute the notion that a physically active lifestyle can completely negate the deleterious effects of overweight/obesity,” the researchers said.

Although increasing physical activity should remain a priority for health policies, “weight loss per se should remain a primary target for health policies aimed at reducing CVD risk in people with overweight/obesity,” they concluded.
 

Interpret findings with caution

“With the ever-increasing public health problem of overweight and obesity, it is useful to assess any measure or measures that can have a favorable or adverse effect on cardiometabolic risk factors and the risk of CVD” Prakash Deedwania, MD, of the University of California, San Francisco, said in an interview.

Dr. Deedwania said he was not entirely surprised by the study findings. “The investigators have correlated only the self-reported level of physical activity (which is not always reliable) to the presence of three cardiac risk factors: hypertension, hypercholesterolemia, and diabetes.”

The study “is not comparable to prior reports that had shown a favorable impact of carefully assessed cardiorespiratory fitness with the risk of CVD,” Dr. Deedwania noted. “However, this is one of the largest population-wide surveillance studies of more than a half million active workers across Spain, and it does show that, despite self-reported physical activity, overweight and obesity are associated with higher risks of hypertension, diabetes, and hypercholesterolemia,” he explained.

“The main message of these findings is that, although physical activity does have a dose-dependent favorable impact on CV risk, the main public health intervention to reduce the risk of CV risk should focus on weight loss in overweight and obese individuals,” Dr. Deedwania emphasized.

“Future studies should focus on comparing various levels of daily activities and routine exercise such as walking, bicycling, etc., with the beneficial impact on cardiometabolic risk factors in overweight and obese individuals,” he said.

Dr. Valenzuela disclosed support from the University of Alcalá. Research by corresponding author Dr. Lucia was funded by grants from Spanish Ministry of Science and Innovation and Fondos FEDER. Dr. Deedwania had no financial conflicts to disclose.
