Low Vitamin D Levels May Signal CVD Risk in Young Adults
TOPLINE:
, small study finds.
METHODOLOGY:
- A secondary analysis of the Activating Brown Adipose Tissue Through Exercise (ACTIBATE) trial assessed the association between serum 25(OH)D levels and CVD risk factors.
- The cross-sectional study used baseline data of in 177 healthy sedentary adults ages 18-25 years (65% women; all White individuals), who were recruited between October 2015 and December 2016 from Granada, a region in the south of Spain.
- Study participants were nonsmokers, led a sedentary lifestyle, and did not have a prior history of CVD or chronic illnesses.
- The CVD risk factors included anthropometrical and body composition profiles, glucose and lipid metabolism, liver, and pro- and anti-inflammatory biomarkers.
- 25(OH)D serum concentrations were measured with a competitive chemiluminescence immunoassay and defined as deficient (< 20 ng/mL), insufficient (21-29 ng/mL), or normal (> 30 ng/mL).
TAKEAWAY:
- The levels correlated inversely with body mass index (BMI; standardized regression coefficient [beta], −0.177; P = .018), fat mass index (beta, −0.195; P = .011), and systolic blood pressure (beta, −0.137; P = .038), after adjusting for sex.
- Glucose metabolism markers (serum glucose and insulin concentrations, insulin/glucose ratio, and homeostatic model assessment of index) also correlated inversely with vitamin D levels.
- The trend was similar for liver markers serum γ-glutamyl transferase and alkaline phosphatase) and the anti-inflammatory marker interleukin-4.
- BMI, waist/hip ratio, fat mass index, blood pressure, and levels of glucose, insulin, , and liver markers were higher in the 44 participants with vitamin D deficiency vs 41 participants with normal vitamin D levels.
IN PRACTICE:
“Collectively, these findings support the idea that 25(OH)D concentrations may be used as a useful marker of CVD status, which can be easily monitored in young individuals,” the authors wrote.

This study was led by first author Francisco J. AmaroGahete, MD, PhD, from the Department of Physiology, Faculty of Medicine, University of Granada, Spain, who also holds positions in other institutions. It was published online in the Journal of Endocrinological Investigation.
LIMITATIONS:
This study could not establish causal relationships due to its cross-sectional design. The results might not apply to younger or older people from different locations and ethnic backgrounds. The gold standard method for analyzing vitamin D levels, liquid chromatography–mass spectrometry, was not used in this study.
DISCLOSURES:
This study was supported by the Spanish Ministry of Economy and Competitiveness, Spanish Ministry of Education, AstraZeneca HealthCare Foundation, and other sources. The authors declared no conflicts of interest.

Prolonged Sitting at Work Ups CVD and All-Cause Mortality, Daily Breaks May Help
However, daily breaks from sitting and leisure-time activity can help mitigate the “serious” risks associated with prolonged occupational sitting, the researchers say.
“As part of modern lifestyles, prolonged occupational sitting is considered normal and has not received due attention, even though its deleterious effect on health outcomes has been demonstrated,” wrote the authors, led by Wayne Gao, PhD, with Taipei Medical University College of Public Health, Taipei City, Taiwan.
“The importance of physical activity and moving around can never be overstated,” Michelle Bloom, MD, director of the cardio-oncology program at NYU Langone Health in New York, who wasn’t involved in the study, told this news organization.
“As a cardiologist, I bring this up at almost every visit with every patient regardless of why they’re seeing me, because I think that patients respond better when their doctor says it than when they just kind of know it in the back of their mind,” said Dr. Bloom, who is also a professor in the Division of Cardiology, NYU Grossman Long Island School of Medicine, New York.
The study was published online in JAMA Network Open.
Prolonged Sitting Hard on the Heart
2020 marked the first time that guidelines on physical activity from the World Health Organization recommended reducing sedentary behaviors owing to their health consequences. Less is known on the specific association of prolonged occupational sitting with health outcomes, especially in the context of low physical activity.
For their study, Dr. Gao and colleagues quantified health risks associated with prolonged sitting on the job and determined whether a certain threshold of physical activity may attenuate this risk.
Participants included 481,688 adults (mean age, 39 years; 53% women) in a health surveillance program in Taiwan. Data on occupational sitting, leisure-time physical activity, lifestyle, and metabolic parameters were collected.
During an average follow up of nearly 13 years, 26,257 participants died; more than half (57%) of the deaths occurred in individuals who mostly sat at work. There were 5371 CVD-related deaths, with 60% occurring in the mostly sitting group.
In multivariate analysis that adjusted for sex, age, education, smoking, drinking, and body mass index, adults who mostly sat at work had a 16% higher risk of dying of any cause (hazard ratio [HR], 1.16; 95% CI, 1.11-1.20) and a 34% increased risk of dying of CVD (HR, 1.34; 95% CI, 1.22-1.46) compared with those who mostly did not sit at work.
Adults who mostly alternated between sitting and not sitting at work were not at increased risk of all-cause mortality compared with individuals who mostly did not at work (HR, 1.01; 95% CI, 0.97-1.05).
Among adults who mostly sat at work and engaged in low (15-29 minutes) or no (< 15 minutes) daily leisure-time activity, increasing activity by 15 and 30 minutes per day, respectively, lowered the risk for mortality to a level similar to that of inactive individuals who mostly do not sit at work.
“Overall, our findings from a large prospective cohort help to strengthen the increasingly accumulating evidence linking a sedentary lifestyle and health risks,” the authors wrote.
“Systemic changes, such as more frequent breaks, standing desks, designated workplace areas for physical activity, and gym membership benefits, can help reduce risk,” they added.
Simple Yet Profound Message
Reached for comment, Anu Lala, MD, with Icahn School of Medicine at Mount Sinai and Mount Sinai Fuster Heart Hospital in New York, said this study provides a “simple yet profound message” about the dangers of prolonged sitting.
The finding of a 16% higher all-cause mortality in those who mostly sat at work after adjustment for major risk factors is “pretty remarkable. And for CVD mortality, it’s double that,” Dr. Lala told this news organization.
“I think we undervalue the importance of movement, however simple it is. Even simple actions, like squatting and standing up have benefits for the heart,” Dr. Lala added.
Dr. Bloom said she tells her patients, “You don’t have to go out tomorrow and run a marathon. Just get up a few times a day, walk a few laps in your office, walk back and forth from the mailbox, walk up and down your steps a couple of times — just do something more than you’re doing already.”
The study had no commercial funding. Dr. Gao and Dr. Bloom have no relevant disclosures. Dr. Lala has serve(d) as a director, officer, partner, employee, advisor, consultant, or trustee for Novartis, AstraZeneca, Merck, Bayer, Novo Nordisk, Cordio, Zoll, and Sequana Medical.

Deaths Linked to Substance Use, CVD on the Rise
TOPLINE:
, with the most pronounced rise among women, American Indians, younger people, rural residents, and users of cannabis and psychostimulants, results of new research suggest.
METHODOLOGY:
- From the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database and using International Classification of Diseases (ICD) codes, researchers collected data on deaths within the United States where both SU and CVD (SU+CVD) were a contributing or an underlying cause and gathered information on location of death (medical facility, home, hospice, nursing home/long-term care facility), demographics (sex, race/ethnicity, age), and region (urban-rural, state).
- Researchers determined crude and age-adjusted mortality rates (AAMRs) per 100,000 population, identified trends in AAMR using annual percent change (APC) and calculated the weighted average of APCs (AAPCs).
- Between 1999 and 2019, there were 636,572 deaths related to CVD+SU, 75.6% of which were among men and 70.6% among non-Hispanic White individuals, with 65% related to alcohol, and where location of death was available, 47.7% occurred in medical facilities.
TAKEAWAY:
- The overall SU+CVD-related AAMR from 1999 to 2019 was 14.3 (95% CI, 14.3-14.3) per 100,000 individuals, with the rate being higher in men (22.5) than in women (6.8) and highest in American Indians or Alaska Natives (37.7) compared with other races/ethnicities.
- Rural areas had higher SU+CVD-related AAMR (15.2; 95% CI, 15.1-15.3) than urban areas, with the District of Columbia having the highest AAMR geographically (25.4), individuals aged 55-69 years having the highest rate agewise (25.1), and alcohol accounting for the highest rate (9.09) among substance types.
- Temporal trends show that the overall SU+CVD-related AAMR increased from 9.9 in 1999 to 21.4 in 2019, a rate that started accelerating in 2012, with an AAPC of 4.0% (95% CI, 3.7-4.3); increases were across all ethnicities and age groups and were particularly pronounced among women (4.8%; 95% CI, 4.5-5.1).
- Cannabis had the highest AAPC of all substances (12.7%), but stimulants had an APC of 21.4 (95% CI, 20.0-22.8) from 2009 to 2019, a period during which stimulants were the fastest-growing substance abuse category.
IN PRACTICE:
These new results identify high-risk groups, which “is crucial for prioritizing preventive measures aiming to reduce substance use and cardiovascular disease-related mortality in these populations,” the researchers wrote.

High Rate of Rehospitalization After First Ischemic Stroke
TOPLINE:
Among patients hospitalized with a first ischemic stroke, 80% were rehospitalized, primarily because of subsequent primary cardiovascular and cerebrovascular diagnoses.
METHODOLOGY:
- To gather information on post-stroke hospital admission, investigators followed 1412 participants (mean age, 72.4 years; 52.1% women, 35.3% Black individuals) from the Atherosclerosis Risk in Communities (ARIC) study who were living in Maryland, Minnesota, North Carolina, and Mississippi.
- Participants were recruited between 1987 and 1989 when they were 45-64 years old and were followed on an annual and then semiannual basis from the index discharge until discharge after their second hospitalization, death, or end of the study in December 2019.
- Specific diagnoses for each hospitalization were based on hospital records, discharge diagnoses, and annual and semiannual phone interviews.
TAKEAWAY:
- During the study period, 1143 hospitalizations occurred over 41,849 person-months.
- 81% of participants were hospitalized over a maximum of 26.6 years of follow-up. Primary cardiovascular and cerebrovascular diagnoses were reported for half of readmissions.
- Over the follow-up period, compared with cardioembolic stroke, readmission risk was lower for thrombotic/lacunar stroke (adjusted hazard ratio [aHR], 0.82; 95% CI, 0.71-0.95) and hemorrhagic stroke (aHR, 0.74; 95% CI, 0.58-0.93). However, when adjusting for atrial fibrillation and competing risk for death, there were no significant differences between stroke subtypes.
- Compared with cardioembolic stroke, thrombotic/lacunar stroke was associated with lower readmission risk within 1 month (aHR, 0.66; 95% CI, 0.46-0.93) and from 1 month to 1 year (aHR, 0.78; 95% CI, 0.62-0.97), and hemorrhagic stroke was associated with lower risk from 1 month to 1 year (aHR, 0.60; 95% CI, 0.41-0.87).
IN PRACTICE:
“These results suggest that prevention strategies focused on cardiovascular and cerebrovascular health warrant further investigation, especially within the first year after incident stroke and perhaps particularly among individuals with an incident cardioembolic stroke,” the authors wrote.

LIMITATIONS:
The ARIC study classification of stroke subtype grouped embolic strokes of undetermined source as thrombotic strokes, and investigators were unable to distinguish between the groups. In addition, there was no way to measure stroke severity, which could have played a role in readmission risk.
DISCLOSURES:
The study was funded by the National Heart, Lung, and Blood Institute, the National Institute of Neurological Disorders and Stroke, and the National Institutes of Health.

TOPLINE:
Among patients hospitalized with a first ischemic stroke, 80% were rehospitalized, primarily because of subsequent primary cardiovascular and cerebrovascular diagnoses.
METHODOLOGY:
- To gather information on post-stroke hospital admission, investigators followed 1412 participants (mean age, 72.4 years; 52.1% women, 35.3% Black individuals) from the Atherosclerosis Risk in Communities (ARIC) study who were living in Maryland, Minnesota, North Carolina, and Mississippi.
- Participants were recruited between 1987 and 1989 when they were 45-64 years old and were followed on an annual and then semiannual basis from the index discharge until discharge after their second hospitalization, death, or end of the study in December 2019.
- Specific diagnoses for each hospitalization were based on hospital records, discharge diagnoses, and annual and semiannual phone interviews.
TAKEAWAY:
- During the study period, 1143 hospitalizations occurred over 41,849 person-months.
- 81% of participants were hospitalized over a maximum of 26.6 years of follow-up. Primary cardiovascular and cerebrovascular diagnoses were reported for half of readmissions.
- Over the follow-up period, compared with cardioembolic stroke, readmission risk was lower for thrombotic/lacunar stroke (adjusted hazard ratio [aHR], 0.82; 95% CI, 0.71-0.95) and hemorrhagic stroke (aHR, 0.74; 95% CI, 0.58-0.93).

Traumatic Brain Injury and CVD: What’s the Link?
The long-term impact of traumatic brain injury (TBI) on neurologic and psychiatric function is well-established, but a growing body of research is pointing to unexpected medical sequalae, including cardiovascular disease (CVD).
A recent review looked at the investigation to date into this surprising connection, not only summarizing study findings but also suggesting potential mechanisms that might account for the association.
“; consequently, they should undergo regular monitoring,” senior author Ross Zafonte, DO, president of Spaulding Rehabilitation Network, Boston, and lead author Saef Izzy, MD, MBChB, a neurologist at the Stroke and Cerebrovascular Center of Brigham and Women’s Hospital, Boston, Massachusetts, told this news organization.
“This holds significant importance for healthcare practitioners, as there exist several strategies to mitigate cardiovascular disease risk — including weight management, adopting a healthy diet, engaging in regular physical activity, and quitting smoking,” they stated.
Leslie Croll, MD, American Heart Association volunteer and assistant professor of clinical neurology at the Temple University Lewis Katz School of Medicine, Philadelphia, Pennsylvania, told this news organization that it’s “extremely important to learn more about the interplay between TBI, neurologic disease, psychiatric complications, and the cardiovascular system.”
Hopefully, she added, “future research will help us understand what kind of cardiovascular disease monitoring and prevention measures stand to give TBI patients the most benefit.”
Chronic Condition
TBI is “a major cause of long-term disability and premature death,” and is “highly prevalent among contact sports players, military personnel (eg, due to injuries sustained during conflict), and the general population (eg, due to falls and road traffic incidents),” the authors wrote.
Most studies pertaining to TBI have “primarily focused on establishing connections between single TBI, repetitive TBI, and their acute and chronic neurological and psychiatric consequences, such as Parkinson’s disease, Alzheimer’s disease, and chronic traumatic encephalopathy (CTE),” Drs. Zafonte and Izzy noted. By contrast, there has been a “notable lack of research attention given to non-neurological conditions associated with TBI.”
They pointed out that recent insights into TBI — particularly the acknowledgment of TBI as an “emerging chronic condition rather than merely an acute aftermath of brain injury” — have come to light through epidemiologic and pathologic investigations involving military veterans, professional American-style football players, and the civilian population. “This recognition opens up an opportunity to broaden our perspective and delve into the medical aspects of health that may be influenced by TBI.”
To broaden the investigation, the researchers reviewed literature published between January 1, 2001, and June 18, 2023. Of 26,335 articles, they narrowed their review down to 15 studies that investigated CVD, CVD risk factors, and cerebrovascular disease in the chronic phase of TBI, including community, military, or sport-related brain trauma, regardless of the timing of disease occurrence with respect to brain injury via TBI or repetitive head impact.
New Cardiovascular Risk
Studies that used national or local registries tended to be retrospective and predominantly conducted in people with preexisting cardiovascular conditions. In these studies, TBI was found to be an independent risk factor for myocardial dysfunction. However, although these studies do provide evidence of elevated cardiovascular risk subsequent to a single TBI, including individuals with preexisting medical comorbidities “makes it difficult to determine the timing of incident cardiovascular disease and cardiovascular risk factors subsequent to brain injury,” they wrote.
However, some studies showed that even individuals with TBI but without preexisting myocardial dysfunction at baseline had a significantly higher risk for CVD than those without a history of TBI.
In fact, several studies included populations without preexisting medical and cardiovascular comorbidities to “better refine the order and timing of CVD and other risk factors in individuals with TBI.”
For example, one study of concussion survivors without preexisting diagnoses showed that cardiovascular, endocrinological, and neuropsychiatric comorbidities occurred at a “significantly higher incidence within 5 years after concussive TBI compared with healthy individuals who were matched in terms of age, race, and sex and didn’t have a TBI exposure.” Other studies yielded similar findings.
Because cardiovascular risk factors and events become more common with age, it’s important to account for age in evaluating the effects of TBI. Although many studies of TBI and subsequent CVD didn’t stratify individuals by age, one 10-year study of people without any known cardiovascular or neuropsychiatric conditions who sustained TBI found that people as young as 18-40 years were more likely to develop hypertension, hyperlipidemia, obesity, and diabetes within 3-5 years following brain injury than matched individuals in the control group.
“Individuals who have encountered TBI, surprisingly even those who are young and in good health with no prior comorbid conditions, face an increased risk of adverse cardiovascular outcomes for an extended duration after the initial event,” Drs. Zafonte and Izzy summarized. “Therefore, it’s imperative that they receive regular and long-term screenings for CVD and associated risk factors.”
Bidirectional Relationship
Brain injury has been associated with acute cardiovascular dysfunction, including autonomic heart-brain axis dysregulation, imbalances between the sympathetic and parasympathetic nervous systems, and excessive catecholamine release, the authors noted.
Drs. Zafonte and Izzy suggested several plausible links between TBI and cardiovascular dysfunction, noting that they are “likely multifaceted, potentially encompassing risk factors that span the pre-injury, injury, and post-injury phases of the condition.”
TBI may induce alterations in neurobiological processes, which have been reported to be associated with an increased risk for CVD (eg, chronic dysfunction of the autonomic system, systemic inflammation, and modifications in the brain-gut connection).
Patients with TBI might develop additional risk factors following the injury, including conditions like posttraumatic stress disorder, depression, and other psychiatric illnesses, which are “known to augment the risk of CVD.”
TBI can lead to subsequent behavioral and lifestyle changes that place patients at an elevated risk for both cardiovascular and cognitive dysfunction when compared to the general population of TBI survivors.
There may be additional as yet undefined risks.
They believe there’s a bidirectional relationship between TBI and CVD. “On one hand, TBI has been associated with an elevated risk of CVD,” they said. “Conversely, cardiovascular risk factors such as diabetes, hypertension, hyperlipidemia, and sleep disturbances that have been demonstrated to negatively influence cognitive function and heighten the risk of dementia. Consequently, this interplay can further compound the long-term consequences of the injury.”
Their work aims to try and disentangle this “complex series of relationships.”
They recommend screening to identify diseases in their earliest and “most manageable phases” because TBI has been “unveiled as an underappreciated risk factor for CVD within contact sports, military, and community setting.”
An effective screening program “should rely on quantifiable and dependable biomarkers such as blood pressure, BMI, waist circumference, blood lipid levels, and glucose. Additionally, it should take into account other factors like smoking habits, physical activity, and dietary choices,” they recommended.
Heart-Brain Connection
Dr. Croll noted that TBI is “associated with many poorly understood physiologic changes and complications, so it’s exciting to see research aimed at clarifying this chronic disease process.”
In recent years, “we have seen a greater appreciation and understanding of the heart-brain connection,” she said. “Moving forward, more research, including TBI research, will target that connection.”
She added that there are probably “multiple mechanisms” at play underlying the connection between TBI and CVD.
Most importantly, “we are increasingly learning that TBI is not only a discrete event that requires immediate treatment but also a chronic disease process,” and when we “think about the substantial long-term morbidity associated with TBI, we should keep increased risk for CVD on top of mind,” said Dr. Croll.
The review received no funding. Izzy reported receiving grants from the US National Institutes of Health (NIH) and 2023 Stepping Strong Innovator Award. Dr. Zafonte reported receiving grants from the NIH and royalties from Springer and Demos publishing for serving as a coeditor of Brain Injury Medicine. Dr. Zafonte has also served as an adviser to Myomo, Oncare.ai, Nanodiagnostics, and Kisbee. He reported evaluating patients in the Massachusetts General Hospital Brain and Body–TRUST Program, which is funded by the NFL Players Association. The other authors’ disclosures are listed on the original paper. Dr. Croll declared no relevant financial relationships.

EHR Tool Enhances Primary Aldosteronism Screening in Hypertensive Patients
Primary aldosteronism (PA) is a frequently overlooked yet common cause of secondary hypertension, presenting significant risk for cardiovascular morbidity and mortality.
But fewer than 4% of at-risk patients receive the recommended screening for PA, leaving a substantial gap in early detection and management, according to Adina F. Turcu, MD, MS, associate professor in endocrinology and internal medicine at University of Michigan Health in Ann Arbor.
In response to this clinical challenge, Dr. Turcu and her colleagues developed a best-practice advisory (BPA) to identify patients who were at risk for PA and embedded it into electronic health record at University of Michigan ambulatory clinics. Her team found that use of the tool led to increased rates of screening for PA, particularly among primary care physicians.
Over a 15-month period, Dr. Turcu and her colleagues tested the BPA through a quality improvement study, identifying 14,603 unique candidates for PA screening, with a mean age of 65.5 years and a diverse representation of ethnic backgrounds.
Notably, 48.1% of these candidates had treatment-resistant hypertension, 43.5% exhibited hypokalemia, 10.5% were younger than 35 years, and 3.1% had adrenal nodules. Of these candidates, 14.0% received orders for PA screening, with 70.5% completing the recommended screening within the system, and 17.4% receiving positive screening results.
The study, conducted over 6 months in 2023, targeted adults with hypertension and at least one of the following: Those who took four or more antihypertensive medications, exhibited hypokalemia, were younger than age 35 years, or had adrenal nodules. Patients previously tested for PA were excluded from the analysis.
The noninterruptive BPA was triggered during outpatient visits with clinicians who specialized in hypertension. The advisory would then offer an order set for PA screening and provide a link to interpretation guidance for results. Clinicians had the option to use, ignore, or decline the BPA.
“Although we were hoping for broader uptake of this EHR-embedded BPA, we were delighted to see an increase in PA screening rates to 14% of identified candidates as compared to an average of less than 3% in retrospective studies of similar populations, including in our own institution prior to implementing this BPA,” Dr. Turcu told this news organization.
Physician specialty played a crucial role in the utilization of the BPA. Internists and family medicine physicians accounted for the majority of screening orders, placing 40.0% and 28.1% of these, respectively. Family practitioners and internists predominantly used the embedded order set (80.3% and 68.9%, respectively).
“Hypertension often gets treated rather than screening for [causes of] secondary hypertension prior to treatment,” said Kaniksha Desai, MD, clinical associate professor and endocrinology quality director at Stanford University School of Medicine, Stanford, California, who was not involved in the research. But “primary hyperaldosteronism is a condition that can be treated surgically and has increased long term cardiovascular consequences if not identified. While guidelines recommend screening at-risk patients, this often can get lost in translation in clinical practice due to many factors, including time constraints and volume of patients.”
Patients who did vs did not undergo screening were more likely to be women, Black, and younger than age 35 years. Additionally, the likelihood of screening was higher among patients with obesity and dyslipidemia, whereas it was lower in those with chronic kidney disease and established cardiovascular complications.
According to Dr. Turcu, the findings from this study suggest that noninterruptive BPAs, especially when integrated into primary care workflows, hold promise as effective tools for PA screening.
When coupled with artificial intelligence to optimize detection yield, these refined BPAs could significantly contribute to personalized care for hypertension, the investigators said.
“Considering that in the United States almost one in two adults has hypertension, such automatized tools become instrumental to busy clinicians, particularly those in primary care,” Dr. Turcu said. “Our results indicate a promising opportunity to meaningfully improve PA awareness and enhance its diagnosis.”
Dr. Turcu reported receiving grants from the National Heart, Lung, and Blood Institute and Doris Duke Foundation, served as an investigator in a CinCor Pharma clinical trial, and received financial support to her institution during the conduct of the study. Dr. Desai reported no relevant financial disclosures.

Primary aldosteronism (PA) is a frequently overlooked yet common cause of secondary hypertension, presenting significant risk for cardiovascular morbidity and mortality.
But fewer than 4% of at-risk patients receive the recommended screening for PA, leaving a substantial gap in early detection and management, according to Adina F. Turcu, MD, MS, associate professor in endocrinology and internal medicine at University of Michigan Health in Ann Arbor.
In response to this clinical challenge, Dr. Turcu and her colleagues developed a best-practice advisory (BPA) to identify patients who were at risk for PA and embedded it into electronic health record at University of Michigan ambulatory clinics. Her team found that use of the tool led to increased rates of screening for PA, particularly among primary care physicians.
Over a 15-month period, Dr. Turcu and her colleagues tested the BPA through a quality improvement study, identifying 14,603 unique candidates for PA screening, with a mean age of 65.5 years and a diverse representation of ethnic backgrounds.
Notably, 48.1% of these candidates had treatment-resistant hypertension, 43.5% exhibited hypokalemia, 10.5% were younger than 35 years, and 3.1% had adrenal nodules. Of these candidates, 14.0% received orders for PA screening, with 70.5% completing the recommended screening within the system, and 17.4% receiving positive screening results.
The study, conducted over 6 months in 2023, targeted adults with hypertension and at least one of the following: Those who took four or more antihypertensive medications, exhibited hypokalemia, were younger than age 35 years, or had adrenal nodules. Patients previously tested for PA were excluded from the analysis.
The noninterruptive BPA was triggered during outpatient visits with clinicians who specialized in hypertension. The advisory would then offer an order set for PA screening and provide a link to interpretation guidance for results. Clinicians had the option to use, ignore, or decline the BPA.
“Although we were hoping for broader uptake of this EHR-embedded BPA, we were delighted to see an increase in PA screening rates to 14% of identified candidates as compared to an average of less than 3% in retrospective studies of similar populations, including in our own institution prior to implementing this BPA,” Dr. Turcu told this news organization.
Physician specialty played a crucial role in the utilization of the BPA. Internists and family medicine physicians accounted for the majority of screening orders, placing 40.0% and 28.1% of these, respectively. Family practitioners and internists predominantly used the embedded order set (80.3% and 68.9%, respectively).

Continued Caution Needed Combining Nitrates With ED Drugs
New research supports continued caution in prescribing a phosphodiesterase-5 inhibitor (PDE5i) to treat erectile dysfunction (ED) in men with heart disease using nitrate medications.
In a large Swedish population study of men with stable coronary artery disease (CAD), the combined use of a PDE5i and nitrates was associated with a higher risk for cardiovascular (CV) morbidity and mortality.
“According to current recommendations, PDE5i are contraindicated in patients taking organic nitrates; however, in clinical practice, both are commonly prescribed, and concomitant use has increased,” first author Ylva Trolle Lagerros, MD, PhD, with Karolinska Institutet, Stockholm, Sweden, told this news organization.
and weigh the benefits of the medication against the possible increased risk for cardiovascular morbidity and mortality given by this combination,” Dr. Lagerros said.
The study was published online in the Journal of the American College of Cardiology (JACC).
The researchers used the Swedish Patient Register and the Prescribed Drug Register to assess the association between PDE5i treatment and CV outcomes in men with stable CAD treated with nitrate medication.
Among 55,777 men with a history of previous myocardial infarction (MI) or coronary revascularization who had filled at least two nitrate prescriptions (sublingual, oral, or both), 5710 also had at least two filled prescriptions of a PDE5i.
In multivariate-adjusted analysis, the combined use of PDE5i treatment with nitrates was associated with an increased relative risk for all studied outcomes, including all-cause mortality, CV and non-CV mortality, MI, heart failure, cardiac revascularization (hazard ratio), and major adverse cardiovascular events.
However, the number of events 28 days following a PDE5i prescription fill was “few, with lower incidence rates than in subjects taking nitrates only, indicating a low immediate risk for any event,” the authors noted in their article.
‘Common Bedfellows’
In a JACC editorial, Glenn N. Levine, MD, with Baylor College of Medicine, Houston, Texas, noted that, “ED and CAD are unfortunate, and all too common, bedfellows. But, as with most relationships, assuming proper precautions and care, they can coexist together for many years, perhaps even a lifetime.”
Dr. Levine noted that PDE5is are “reasonably safe” in most patients with stable CAD and only mild angina if not on chronic nitrate therapy. For those on chronic oral nitrate therapy, the use of PDE5is should continue to be regarded as “ill-advised at best and generally contraindicated.”
In some patients on oral nitrate therapy who want to use a PDE5i, particularly those who have undergone revascularization and have minimal or no angina, Dr. Levine said it may be reasonable to initiate a several-week trial of the nitrate therapy (or on a different class of antianginal therapy) and assess if the patient remains relatively angina-free.
In those patients with just rare exertional angina at generally higher levels of activity or those prescribed sublingual nitroglycerin “just in case,” it may be reasonable to prescribe PDE5i after a “clear and detailed” discussion with the patient of the risks for temporarily combining PDE5i and sublingual nitroglycerin.
Dr. Levine said these patients should be instructed not to take nitroglycerin within 24 hours of using a shorter-acting PDE5i and within 48 hours of using the longer-acting PDE5i tadalafil.
They should also be told to call 9-1-1 if angina develops during sexual intercourse and does not resolve upon cessation of such sexual activity, as well as to make medical personnel aware that they have recently used a PDE5i.
The study was funded by Region Stockholm, the Center for Innovative Medicine, and Karolinska Institutet. The researchers and editorial writer had declared no relevant conflicts of interest.

New Insights Into Mortality in Takotsubo Syndrome
TOPLINE:
Mortality in patients with takotsubo syndrome (TTS), sometimes called broken heart syndrome or stress-induced cardiomyopathy is substantially higher than that in the general population and comparable with that in patients having myocardial infarction (MI), results of a new case-control study showed. The rates of medication use are similar for TTS and MI, despite no current clinical trials or recommendations to guide such therapies, the authors noted.
METHODOLOGY:
- The study included 620 Scottish patients (mean age, 66 years; 91% women) with TTS, a potentially fatal condition that mimics MI, predominantly affects middle-aged women, and is often triggered by stress.
- The analysis also included two age-, sex-, and geographically matched control groups: Representative participants from the general Scottish population (1:4) and patients with acute MI (1:1).
- Using comprehensive national data sets, researchers extracted information for all three cohorts on prescribing of cardiovascular and noncardiovascular medications, including the duration of dispensing and causes of death, and clustered the major causes of death into 17 major groups.
- At a median follow-up of 5.5 years, there were 722 deaths (153 in patients with TTS, 195 in those with MI, and 374 in the general population cohort).
TAKEAWAY:
- and slightly lower than that in patients having MI (HR, 0.76; 95% CI, 0.62-0.94; P = .012), with cardiovascular causes, particularly heart failure, being the most strongly associated with TTS (HR, 2.47; 95% CI, 1.81-3.39; P < .0001 vs general population), followed by pulmonary causes. Noncardiovascular mortality was similar in TTS and MI.
- Prescription rates of cardiovascular and noncardiovascular medications were similar between patients with TTS and MI.
- The only cardiovascular therapy associated with lower mortality in patients with TTS was angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy (P = .0056); in contrast, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, antiplatelet agents, and statins were all associated with improved survival in patients with MI.
- Diuretics were associated with worse outcomes in both patients with TTS and MI, as was psychotropic therapy.
IN PRACTICE:
“These findings may help to lay the foundations for further exploration of potential mechanisms and treatments” for TTS, an “increasingly recognized and potentially fatal condition,” the authors concluded.
In an accompanying comment, Rodolfo Citro, MD, PHD, Cardiovascular and Thoracic Department, San Giovanni di Dio e Ruggi d’ Aragona University Hospital, Salerno, Italy, and colleagues said the authors should be commended for providing data on cardiovascular mortality “during one of the longest available follow-ups in TTS,” adding the study “suggests the importance of further research for more appropriate management of patients with acute and long-term TTS.”
SOURCE:
The research was led by Amelia E. Rudd, MSC, Aberdeen Cardiovascular and Diabetes Centre, University of Aberdeen and NHS Grampian, Aberdeen, Scotland. It was published online in the Journal of the American College of Cardiology.
LIMITATIONS:
Complete alignment of all variables related to clinical characteristics of patients with TTS and MI wasn’t feasible. During the study, TTS was still relatively unfamiliar to clinicians and underdiagnosed. As the study used a national data set of routinely collected data, not all desirable information was available, including indications of why drugs were prescribed or discontinued, which could have led to imprecise results. As the study used nonrandomized data, causality can’t be assumed.
DISCLOSURES:
Dr. Rudd had no relevant conflicts of interest. Study author Dana K. Dawson, Aberdeen Cardiovascular and Diabetes Centre, University of Aberdeen, Scotland, declared receiving the Chief Scientist Office Scotland award CGA-16-4 and the BHF Research Training Fellowship. Commentary authors had no relevant conflicts of interest.

Severely Irregular Sleep Patterns and OSA Prompt Increased Odds of Hypertension
TOPLINE:
Severe sleep irregularity often occurs with obstructive sleep apnea (OSA), and this combination approximately doubled the odds of hypertension in middle-aged individuals.
METHODOLOGY:
- OSA has demonstrated an association with hypertension, but data on the impact of sleep irregularity on this relationship are lacking.
- The researchers used the recently developed sleep regularity index (SRI) to determine sleep patterns using a scale of 0-100 (with higher numbers indicating greater regularity) to assess relationships between OSA, sleep patterns, and hypertension in 602 adults with a mean age of 57 years.
- The study’s goal was an assessment of the associations between sleep regularity, OSA, and hypertension in a community sample of adults with normal circadian patterns.
TAKEAWAY:
- The odds of OSA were significantly greater for individuals with mildly irregular or severely irregular sleep than for regular sleepers (odds ratios, 1.97 and 2.06, respectively).
- Individuals with OSA and severely irregular sleep had the highest odds of hypertension compared with individuals with no OSA and regular sleep (OR, 2.34).
- However, participants with OSA and regular sleep or mildly irregular sleep had no significant increase in hypertension risk.
IN PRACTICE:
“Irregular sleep may be an important marker of OSA-related sleep disruption and may be an important modifiable health target,” the researchers wrote.
SOURCE:
The study was led by Kelly Sansom, a PhD candidate at the Centre for Sleep Science at the University of Western Australia, Albany. The study was published online in the journal Sleep.
LIMITATIONS:
The cross-sectional design prevented conclusions of causality, and the SRI is a nonspecific measure that may capture a range of phenotypes with one score; other limitations included the small sample sizes of sleep regularity groups and the use of actigraphy to collect sleep times.
DISCLOSURES:
The study was supported by an Australian Government Research Training Program Scholarship and the Raine Study PhD Top-up Scholarship; the Raine Study Scholarship is supported by the NHMRC, the Centre for Sleep Science, School of Anatomy, Physiology & Human Biology of the University of Western Australia, and the Lions Eye Institute. The researchers had no financial conflicts to disclose.

- OSA has demonstrated an association with hypertension, but data on the impact of sleep irregularity on this relationship are lacking.
- The researchers used the recently developed sleep regularity index (SRI) to determine sleep patterns using a scale of 0-100 (with higher numbers indicating greater regularity) to assess relationships between OSA, sleep patterns, and hypertension in 602 adults with a mean age of 57 years.
- The study’s goal was an assessment of the associations between sleep regularity, OSA, and hypertension in a community sample of adults with normal circadian patterns.
TAKEAWAY:
- The odds of OSA were significantly greater for individuals with mildly irregular or severely irregular sleep than for regular sleepers (odds ratios, 1.97 and 2.06, respectively).
- Individuals with OSA and severely irregular sleep had the highest odds of hypertension compared with individuals with no OSA and regular sleep (OR, 2.34).
- However, participants with OSA and regular sleep or mildly irregular sleep had no significant increase in hypertension risk.
IN PRACTICE:
“Irregular sleep may be an important marker of OSA-related sleep disruption and may be an important modifiable health target,” the researchers wrote.
SOURCE:
The study was led by Kelly Sansom, a PhD candidate at the Centre for Sleep Science at the University of Western Australia, Albany. The study was published online in the journal Sleep.
LIMITATIONS:
The cross-sectional design prevented conclusions of causality, and the SRI is a nonspecific measure that may capture a range of phenotypes with one score; other limitations included the small sample sizes of sleep regularity groups and the use of actigraphy to collect sleep times.
DISCLOSURES:
The study was supported by an Australian Government Research Training Program Scholarship and the Raine Study PhD Top-up Scholarship; the Raine Study Scholarship is supported by the NHMRC, the Centre for Sleep Science, School of Anatomy, Physiology & Human Biology of the University of Western Australia, and the Lions Eye Institute. The researchers had no financial conflicts to disclose.

Temporary Higher Stroke Rate After TAVR
TOPLINE:
Patients undergoing transcatheter aortic valve replacement (TAVR) have a higher risk for stroke for up to 2 years compared with an age- and sex-matched population, after which their risks are comparable, results of a large Swiss registry study suggest.
METHODOLOGY:
- The study included 11,957 patients from the prospective SwissTAVI Registry, an ongoing mandatory cohort study enrolling consecutive patients undergoing TAVR in Switzerland.
- The study population, which had a mean age of 81.8 years and mean Society of Thoracic Surgeons Predicted Risk of Mortality (STS PROM) of 4.62, with 11.8% having a history of cerebrovascular accident (CVA) and 32.3% a history of atrial fibrillation, underwent TAVR at 15 centers between February 2011 and June 2021.
- The primary outcome was the incidence of stroke, with secondary outcomes including the incidence of CVA, a composite of stroke and transient ischemic attack (TIA).
- Researchers calculated standardized stroke ratios (SSRs) and compared stroke trends in patients undergoing TAVR with those of an age- and sex-matched general population in Switzerland derived from the 2019 Global Burden of Disease (GBD) study.
TAKEAWAY:
- , accounting for 69% of these events.
- After excluding 30-day events, the 1-year incidence rates of CVA and stroke were 1.7% and 1.4%, respectively, followed by an annual stroke incidence of 1.2%, 0.8%, 0.9%, and 0.7% in the second, third, fourth, and fifth years post TAVR, respectively.
- Only increased age and moderate/severe paravalvular leakage (PVL) at discharge were associated with an increased risk for early stroke (up to 30 days post TAVR), whereas dyslipidemia and history of atrial fibrillation and of CVA were associated with an increased risk for late stroke (30 days to 5 years after TAVR).
- SSR in the study population returned to a level comparable to that expected in the general Swiss population after 2 years and through to 5 years post-TAVR.
IN PRACTICE:
Although the study results “are reassuring” with respect to stroke risk beyond 2 years post TAVR, “our findings underscore the continued efforts of stroke-prevention measures” early and longer term, wrote the authors.
In an accompanying editorial, Lauge Østergaard, MD, PhD, Department of Cardiology, University of Copenhagen, Denmark, noted the study suggests reduced PVL could lower the risk for early stroke following TAVR and “highlights how assessment of usual risk factors (dyslipidemia and atrial fibrillation) could help reduce the burden of stroke in the long term.”
SOURCE:
The study was carried out by Taishi Okuno, MD, Department of Cardiology, Bern University Hospital, University of Bern, Switzerland, and colleagues. It was published online in the Journal of the American College of Cardiology (JACC): Cardiovascular Interventions.
LIMITATIONS:
The study couldn’t investigate the association between antithrombotic regimens and the risk for CVA. Definitions of CVA in the SwissTAVI Registry might differ from those used in the GBD study from which the matched population data were derived. The general population wasn’t matched on comorbidities usually associated with elevated stroke risk, which may have led to underestimation of stroke. As the mean age in the study was 82 years, results may not be extrapolated to a younger population.
DISCLOSURES:
The SwissTAVI registry is supported by the Swiss Heart Foundation, Swiss Working Group of Interventional Cardiology and Acute Coronary Syndromes, Medtronic, Edwards Lifesciences, Boston Scientific/Symetis, JenaValve, and St. Jude Medical. Dr. Okuno has no relevant conflicts of interest; see paper for disclosures of other study authors. Dr. Østergaard has received an independent research grant from the Novo Nordisk Foundation.
