Hypertension

Certain antihypertensive medications, particularly diuretics, are linked to lower Alzheimer’s disease neuropathology and other brain disease processes, new research shows.

Investigators found that use of any antihypertensive was associated with an 18% decrease in Alzheimer’s disease neuropathology, a 22% decrease in Lewy bodies, and a 40% decrease in TAR DNA-binding protein 43 (TDP-43), a protein relevant to several neurodegenerative diseases. Diuretics in particular appear to be driving the association.

Although diuretics might be a better option for preventing brain neuropathology, it’s too early to make firm recommendations solely on the basis of these results as to what blood pressure–lowering agent to prescribe a particular patient, said study investigator Ahmad Sajjadi, MD, assistant professor of neurology, University of California, Irvine.

“This is early stages and preliminary results,” said Dr. Sajjadi, “but it’s food for thought.”

The findings were presented at the 2021 annual meeting of the American Neurological Association.
 

Autopsy data

The study included 3,315 individuals who had donated their brains to research. The National Alzheimer’s Coordinating Center maintains a database that includes data from 32 Alzheimer’s disease research centers in the United States. Participants in the study must have visited one of these centers within 4 years of death. Each person whose brain was included in the study underwent two or more BP measurements on at least 50% of visits.

The mean age at death was 81.7 years, and the mean time between last visit and death was 13.1 months. About 44.4% of participants were women, 57.0% had at least a college degree, and 84.7% had cognitive impairment.

Researchers defined hypertension as systolic BP of at least 130 mm Hg, diastolic BP of at least 80 mm Hg, mean arterial pressure of at least 100 mm Hg, and pulse pressure of at least 60 mm Hg.

Antihypertensive medications that were evaluated included antiadrenergic agents, ACE inhibitors, angiotensin II receptor blockers, beta blockers, calcium channel blockers, diuretics, vasodilators, and combination therapies.

The investigators assessed the number of neuropathologies. In addition to Alzheimer’s disease neuropathology, which included amyloid-beta, tau, Lewy bodies, and TDP-43, they also assessed for atherosclerosis, arteriolosclerosis, cerebral amyloid angiopathy, frontotemporal lobar degeneration, and hippocampal sclerosis.

Results showed that use of any antihypertensive was associated with a lower likelihood of Alzheimer’s disease neuropathology (odds ratio, 0.822), Lewy bodies (OR, 0.786), and TDP 43 (OR, 0.597). Use of antihypertensives was also associated with increased odds of atherosclerosis (OR, 1.217) (all P < .5.)

The study showed that hypertensive systolic BP was associated with higher odds of Alzheimer’s disease neuropathology (OR, 1.28; P < .5).

Differences by drug type

Results differed in accordance with antihypertensive class. Angiotensin II receptor blockers decreased the odds of Alzheimer’s disease neuropathology by 40% (OR, 0.60; P < .5). Diuretics decreased the odds of Alzheimer’s disease by 36% (OR, 0.64; P < .001) and of hippocampal sclerosis by 32% (OR, 0.68; P < .5).

“We see diuretics are a main driver, especially for lower odds of Alzheimer’s disease and lower odds of hippocampal sclerosis,” said lead author Hanna L. Nguyen, a first-year medical student at the University of California, Irvine.

The results indicate that it is the medications, not BP levels, that account for these associations, she added.

One potential mechanism linking antihypertensives to brain pathology is that with these agents, BP is maintained in the target zone. Blood pressure that’s too high can damage blood vessels, whereas BP that’s too low may result in less than adequate perfusion, said Ms. Nguyen.

These medications may also alter pathways leading to degeneration and could, for example, affect the apo E mechanism of Alzheimer’s disease, she added.

The researchers plan to conduct subset analyses using apo E genetic status and age of death.

Although this is a “massive database,” it has limitations. For example, said Dr. Sajjadi, it does not reveal when patients started taking BP medication, how long they had been taking it, or why.

“We don’t know the exact the reason they were taking these medications. Was it just hypertension, or did they also have heart disease, stroke, a kidney problem, or was there another explanation,” he said.

Following the study presentation, session comoderator Krish Sathian, MBBS, PhD, professor of neurology, neural, and behavioral sciences, and psychology and director of the Neuroscience Institute, Penn State University, Hershey, called this work “fascinating. It provides a lot of data that really touches on everyday practice,” inasmuch as clinicians often prescribe antihypertensive medications and see patients with these kinds of brain disorders.

The investigators and Dr. Sathian reported no relevant financial relationships.

Increased mental health needs, higher acuity from delayed appointments, and added questions and conversations surrounding COVID-19 are forcing primary care offices to rethink priorities in office visits.

Evidence of this came from the latest Primary Care Collaborative (PCC) survey, which found that primary care clinicians are seeing more complex patients requiring longer appointments in the wake of COVID-19.

The PCC with the Larry A. Green Center regularly surveys primary care clinicians. This round of questions came August 14-17 and included 1,263 respondents from 49 states, the District of Columbia, and two territories.

More than 7 in 10 (71%) respondents said their patients are more complex and nearly the same percentage said appointments are taking more time.

Ann Greiner, president and CEO of the PCC, said in an interview that 55% of respondents reported that clinicians are struggling to keep up with pent-up demand after patients have delayed or canceled care. Sixty-five percent in the survey said they had seen a rise in children’s mental health issues, and 58% said they were unsure how to help their patients with long COVID.

In addition, primary care clinicians are having repeated conversations with patients on why they should get a vaccine and which one.

“I think that’s adding to the complexity. There is a lot going on here with patient trust,” Ms. Greiner said.
 

‘We’re going to be playing catch-up’

Jacqueline Fincher, MD, an internist in Thompson, Ga., said in an interview that appointments have gotten longer and more complex in the wake of the pandemic – “no question.”

The immediate past president of the American College of Physicians is seeing patients with chronic disease that has gone untreated for sometimes a year or more, she said.

“Their blood pressure was not under good control, they were under more stress, their sugars were up and weren’t being followed as closely for conditions such as congestive heart failure,” she said.

Dr. Fincher, who works in a rural practice 40 miles from Augusta, Ga., with her physician husband and two other physicians, said patients are ready to come back in, “but I don’t have enough slots for them.”

She said she prioritizes what to help patients with first and schedules the next tier for the next appointment, but added, “honestly, over the next 2 years we’re going to be playing catch-up.”

At the same time, the CDC has estimated that 45% of U.S. adults are at increased risk for complications from COVID-19 because of cardiovascular disease, diabetes, respiratory disease, hypertension, or cancer. Rates ranged from 19.8% for people 18-29 years old to 80.7% for people over 80 years of age.
 

Long COVID could overwhelm existing health care capacity

Primary care physicians are also having to diagnose sometimes “invisible” symptoms after people have recovered from acute COVID-19 infection. Diagnosing takes intent listening to patients who describe symptoms that tests can’t confirm.

As this news organization has previously reported, half of COVID-19 survivors report postacute sequelae of COVID-19 (PASC) lasting longer than 6 months.

“These long-term PASC effects occur on a scale that could overwhelm existing health care capacity, particularly in low- and middle-income countries,” the authors wrote.
 

Anxiety, depression ‘have gone off the charts’

“That got extremely exacerbated during the pandemic. Anxiety and depression have gone off the charts,” said Dr. Loeb, who prefers the pronoun “they.”

Dr. Loeb cares for a large number of transgender patients. As offices reopen, some patients are having trouble reintegrating into the workplace and resuming social contacts. The primary care doctor says appointments can get longer because of the need to complete tasks, such as filling out forms for Family Medical Leave Act for those not yet ready to return to work.

COVID-19–related fears are keeping many patients from coming into the office, Dr. Loeb said, either from fear of exposure or because they have mental health issues that keep them from feeling safe leaving the house.

“That really affects my ability to care for them,” they said.

Loss of employment in the pandemic or fear of job loss and subsequent changing of insurance has complicated primary care in terms of treatment and administrative tasks, according to Dr. Loeb.

To help treat patients with acute mental health issues and manage other patients, Dr. Loeb’s practice has brought in a social worker and a therapist.

Team-based care is key in the survival of primary care practices, though providing that is difficult in the smaller clinics because of the critical mass of patients needed to make it viable, they said.

“It’s the only answer. It’s the only way you don’t drown,” Dr. Loeb added. “I’m not drowning, and I credit that to my clinic having the help to support the mental health piece of things.”
 

Rethinking workflow

Tricia McGinnis, MPP, MPH, executive vice president of the nonprofit Center for Health Care Strategies (CHCS) says complexity has forced rethinking workflow.

“A lot of the trends we’re seeing in primary care were there pre-COVID, but COVID has exacerbated those trends,” she said in an interview.

“The good news ... is that it was already becoming clear that primary care needed to provide basic mental health services and integrate with behavioral health. It had also become clear that effective primary care needed to address social issues that keep patients from accessing health care,” she said.

Expanding care teams, as Dr. Loeb mentioned, is a key strategy, according to Ms. McGinnis. Potential teams would include the clinical staff, but also social workers and community health workers – people who come from the community primary care is serving who can help build trust with patients and connect the patient to the primary care team.

“There’s a lot that needs to happen that the clinician doesn’t need to do,” she said.

Telehealth can be a big factor in coordinating the team, Ms. McGinnis added.

“It’s thinking less about who’s doing the work, but more about the work that needs to be done to keep people healthy. Then let’s think about the type of workers best suited to perform those tasks,” she said.

As for reimbursing more complex care, population-based, up-front capitated payments linked to high-quality care and better outcomes will need to replace fee-for-service models, according to Ms. McGinnis.

That will provide reliable incomes for primary care offices, but also flexibility in how each patient with different levels of complexity is managed, she said.

Ms. Greiner, Dr. Fincher, Dr. Loeb, and Ms. McGinnis have no relevant financial relationships.

“There’s a lot that needs to happen that the clinician doesn’t need to do,” she said.

Telehealth can be a big factor in coordinating the team, Ms. McGinnis added.

“It’s thinking less about who’s doing the work, but more about the work that needs to be done to keep people healthy. Then let’s think about the type of workers best suited to perform those tasks,” she said.

As for reimbursing more complex care, population-based, up-front capitated payments linked to high-quality care and better outcomes will need to replace fee-for-service models, according to Ms. McGinnis.

That will provide reliable incomes for primary care offices, but also flexibility in how each patient with different levels of complexity is managed, she said.

Ms. Greiner, Dr. Fincher, Dr. Loeb, and Ms. McGinnis have no relevant financial relationships.

In a new scientific statement on diet and lifestyle recommendations, the American Heart Association is highlighting, for the first time, structural challenges that impede the adoption of heart-healthy dietary patterns.

American Heart Association

This is in addition to stressing aspects of diet that improve cardiovascular health and reduce cardiovascular risk, with an emphasis on dietary patterns and food-based guidance beyond naming individual foods or nutrients.

The 2021 Dietary Guidance to Improve Cardiovascular Health scientific statement, developed under Alice H. Lichtenstein, DSc, chair of the AHA writing group, provides 10 evidence-based guidance recommendations to promote cardiometabolic health.

“The way to make heart-healthy choices every day,” said Dr. Lichtenstein, of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston, in a statement, “is to step back, look at the environment in which you eat, whether it be at home, at work, during social interaction, and then identify what the best choices are. And if there are no good choices, then think about how you can modify your environment so that there are good choices.”

The statement, published in Circulation, underscores growing evidence that nutrition-related chronic diseases have maternal-nutritional origins, and that prevention of pediatric obesity is a key to preserving and prolonging ideal cardiovascular health.

The features are as follows:

• Adjust energy intake and expenditure to achieve and maintain a healthy body weight. To counter the shift toward higher energy intake and more sedentary lifestyles over the past 3 decades, the statement recommends at least 150 minutes of moderate physical activity per week, adjusted for individual’s age, activity level, sex, and size.
• Eat plenty of fruits and vegetables; choose a wide variety. Observational and intervention studies document that dietary patterns rich in varied fruits and vegetables, with the exception of white potatoes, are linked to a lower risk of cardiovascular disease (CVD). Also, whole fruits and vegetables, which more readily provide fiber and satiety, are preferred over juices.
• Choose whole grain foods and products made mostly with whole grains rather than refined grains. Evidence from observational, interventional, and clinical studies confirm the benefits of frequent consumption of whole grains over infrequent consumption or over refined grains in terms of CVD risk, coronary heart disease (CHD), stroke, metabolic syndrome, cardiometabolic risk factors, laxation, and gut microbiota.
• Choose healthy sources of protein, mostly from plants (legumes and nuts).
• Higher intake of legumes, which are rich in protein and fiber, is associated with lower CVD risk, while higher nut intake is associated with lower risks of CVD, CHD, and stroke mortality/incidence. Replacing animal-source foods with plant-source whole foods, beyond health benefits, lowers the diet’s carbon footprint. Meat alternatives are often ultraprocessed and evidence on their short- and long-term health effects is limited. Unsaturated fats are preferred, as are lean, nonprocessed meats.
• Use liquid plant oils rather than tropical oils (coconut, palm, and palm kernel), animal fats (butter and lard), and partially hydrogenated fats. Saturated and trans fats (animal and dairy fats, and partially hydrogenated fat) should be replaced with nontropical liquid plant oils. Evidence supports cardiovascular benefits of dietary unsaturated fats, especially polyunsaturated fats primarily from plant oils (e.g. soybean, corn, safflower and sunflower oils, walnuts, and flax seeds).
• Choose minimally processed foods instead of ultraprocessed foods. Because of their proven association with adverse health outcomes, including overweight and obesity, cardiometabolic disorders (type 2 diabetes, CVD), and all-cause mortality, the consumption of many ultraprocessed foods is of concern. Ultraprocessed foods include artificial colors and flavors and preservatives that promote shelf stability, preserve texture, and increase palatability. A general principle is to emphasize unprocessed or minimally processed foods.
• Minimize intake of beverages and foods with added sugars. Added sugars (commonly glucose, dextrose, sucrose, corn syrup, honey, maple syrup, and concentrated fruit juice) are tied to elevated risk for type 2 diabetes, high cholesterol, and excess body weight. Findings from meta-analyses on body weight and metabolic outcomes for replacing added sugars with low-energy sweeteners are mixed, and the possibility of reverse causality has been raised.
• Choose and prepare foods with little or no salt. In general, the effects of sodium reduction on blood pressure tend to be higher in Black people, middle-aged and older people, and those with hypertension. In the United States, the main combined sources of sodium intake are processed foods, those prepared outside the home, packaged foods, and restaurant foods. Potassium-enriched salts are a promising alternative.
• If you don’t drink alcohol, don’t start; if you choose to drink, limit intake.
• While relationships between alcohol intake and cardiovascular outcomes are complex, the 2020 Dietary Guidelines Advisory Committee recently concluded that those who do drink should consume no more than one drink per day and should not drink alcohol in binges; the 2020 Dietary Guidelines for Americans con­tinues to recommend no more than one drink per day for women and two drinks per day for men.
• Adhere to the guidance regardless in all settings. Food-based dietary guidance applies to all foods and beverages, regardless of where prepared, procured, and consumed. Policies should be enacted that encourage healthier default options (for example, whole grains, minimized sodium and sugar content).

Recognizing impediments

The AHA/ASA scientific statement closes with the declaration: “Creating an environment that facilitates, rather than impedes, adherence to heart-healthy dietary patterns among all individuals is a public health imperative.” It points to the National Institutes of Health’s 2020-2030 Strategic Plan for National Institutes of Health Nutrition Research, which focuses on precision nutrition as a means “to determine the impact on health of not only what individuals eat, but also of why, when, and how they eat throughout the life course.”

Ultimately, precision nutrition may provide personalized diets for CVD prevention. But the “food environment,” often conditioned by “rampant nutrition misinformation” through local, state, and federal practices and policies, may impede the adoption of heart-healthy dietary patterns. Factors such as targeted food marketing (for example, of processed food and beverages in minority neighborhoods), structural racism, neighborhood segregation, unhealthy built environments, and food insecurity create environments in which unhealthy foods are the default option.”

These factors compound adverse dietary and health effects, and underscore a need to “directly combat nutrition misinformation among the public and health care professionals.” They also explain why, despite widespread knowledge of heart-healthy dietary pattern components, little progress has been made in achieving dietary goals in the United States.

According to the latest meta-analysis of sham-controlled randomized trials, catheter-based renal sympathetic denervation produces clinically meaningful reductions in blood pressure with acceptable safety, but the strategy is not yet regarded as ready for prime time, according to a summary of the results to be presented at the Transcatheter Cardiovascular Therapeutics annual meeting.

This meta-analysis was based on seven blinded trials, all of which associated denervation with a reduction in systolic ambulatory BP, according to Yousif Ahmad, BMBS, PhD, an interventional cardiologist at Yale University, New Haven, Conn.

Although the BP-lowering advantage in two of these studies did not reach statistical significance, the other five did, and all the data moved in the same direction.

For ambulatory diastolic pressure, the effect was more modest. One of the studies showed essentially a neutral effect. The reductions were statistically significant in only two, but, again, the data moved in the same direction in six of the studies, and a random-effects analysis suggested that the reductions, although modest, were potentially meaningful, according to Dr. Ahmad.

Overall, at a mean follow-up of 4.5 months, the reductions in ambulatory systolic and diastolic BPs were 3.61 and 1.85 mm Hg, respectively. The benefit was about the same whether renal denervation was or was not performed on the background of antihypertensive drugs, which was permitted in five of the seven trials. In the other two, all patients were off hypertensive medication.
 

Office-based systolic reduction: 6 mm Hg

When the same analysis was performed for office-based BP reductions, which were available for five of the seven trials, the overall reductions based on the meta-analysis were 5.86 and 3.63 mm Hg for the systolic and diastolic pressures, respectively. Again, background antihypertensive therapy was not a factor.

Of the seven trials, three randomized fewer than 100 patients. The largest, SYMPLICITY HTN-3, randomized 491 patients in 2:1 ratio to denervation or sham.

Three of the studies in the meta-analysis were trials of the Symplicity flex device. Another two evaluated the Symplicity Spyral catheter. Both deliver radiofrequency energy to for denervation. The Paradise device, the focus of the remaining two trials, employs energy in the form of ultrasound.

According to Dr. Ahmad, adverse events regardless of device were rare and not more common among those in the active treatment arm than in those treated with a sham procedure. Although one of these trials, RADIANCE-HTN SOLO associated denervation with efficacy and safety out to 12 months , Dr. Ahmad concluded that the mean follow-up of 4.5 months is not sufficient to consider long-term effects.

More than 20 meta-analyses published so far

By one count, there have been more than 20 meta-analyses of renal denervation published previously yet this intervention is still considered “controversial,” according to Dr. Ahmad. Relative to the previous meta-analyses, this included the RADIANCE-HTN TRIO trial, which is the latest such sham-controlled study and added 136 patients to the dataset of high-quality trials.

Basically, the results led Dr. Ahmad to conclude that, although the treatment effect is modest, it could be valuable in specific groups of patients, such as those reluctant or unable to take multiple medications or any medications at all. In addition to generating more data on efficacy and safety, he said longer follow-up is also needed for calculations of cost-effectiveness. Larger-scale observational studies might be one way of collecting these data, he reported.

The results of this study were published online in JACC Cardiovascular Interventions with an accompanying editorial by David E. Kandzari, MD, director of interventional cardiology, Piedmont Hart Institute, Atlanta.

Commenting on the large pile of meta-analyses, sometimes published months apart, Dr. Kandzari explained that their “short half-life” is a product of the continuous updating of data with new trials. For a procedure that remains controversial, he said these constant relooks are inevitable.

“My point is that, with more studies, we can expect to see more meta-analyses. It is just the way this is going to work,” Dr. Kandzari said in an interview.
 

Individual study data also relevant

Even as the authors of these analyses attempt to cull the best data from the most rigorously performed trials, “we are also going to have to look at the individual studies, because of the differences in the trial designs, particularly the devices used,” according to Dr. Kandzari, who was the principle investigator of the sham-controlled SPYRAL HTN-ON MED trial.

So far, the data, despite some inconsistencies, have supported “clinically meaningful” BP reductions and acceptable safety regardless of the device used, according to Dr. Kandzari. Although he also agrees with the basic premise that more long-term data are needed to better determine how renal denervation should be applied in management of hypertension, he does think it will eventually find a role that is “complimentary to, rather than a replacement for, drugs.”

“The effect is modest, but keep in mind that the effect size is similar to that of a single oral medication, and there are some features, such as an always-on 24-hour effect that could be useful,” he said.

“We have enough of a signal to start thinking of how this will be enveloped into routine care,” he said.

But it is not ready yet. This was the point made by Dr. Ahmad, and it was seconded by Dr. Kandzari. One of the senior authors of the meta-analysis, Deepak Bhatt, MD, executive director of interventional cardiovascular programs, Brigham and Women’s Health, Boston, was also asked to weigh on when it will be ready for prime time.

“At a minimum, I would recommend completion of ongoing sham-controlled randomized trials before considering clinical use of renal denervation. Longer term safety and durability data, as well as data on cost-effectiveness, are all still needed – preferably from randomized trials as opposed to registries,” he said.

“Ideally, larger sham-controlled trials with longer follow-up and clinical endpoints, as opposed to only blood pressure measurements, would be performed, although I am not aware of any plans at present,” he added.

Dr. Ahmad reported no financial relationships relevant to this research. Dr. Bhatt has financial relationships with more than 30 pharmaceutical companies, including those developing products relevant to hypertension and renal denervation. Dr. Kandzari reported financial relationships with Ablative Solutions and Medtronic.

Of the seven trials, three randomized fewer than 100 patients. The largest, SYMPLICITY HTN-3, randomized 491 patients in 2:1 ratio to denervation or sham.

Three of the studies in the meta-analysis were trials of the Symplicity flex device. Another two evaluated the Symplicity Spyral catheter. Both deliver radiofrequency energy to for denervation. The Paradise device, the focus of the remaining two trials, employs energy in the form of ultrasound.

According to Dr. Ahmad, adverse events regardless of device were rare and not more common among those in the active treatment arm than in those treated with a sham procedure. Although one of these trials, RADIANCE-HTN SOLO associated denervation with efficacy and safety out to 12 months , Dr. Ahmad concluded that the mean follow-up of 4.5 months is not sufficient to consider long-term effects.

More than 20 meta-analyses published so far

By one count, there have been more than 20 meta-analyses of renal denervation published previously yet this intervention is still considered “controversial,” according to Dr. Ahmad. Relative to the previous meta-analyses, this included the RADIANCE-HTN TRIO trial, which is the latest such sham-controlled study and added 136 patients to the dataset of high-quality trials.

Basically, the results led Dr. Ahmad to conclude that, although the treatment effect is modest, it could be valuable in specific groups of patients, such as those reluctant or unable to take multiple medications or any medications at all. In addition to generating more data on efficacy and safety, he said longer follow-up is also needed for calculations of cost-effectiveness. Larger-scale observational studies might be one way of collecting these data, he reported.

The results of this study were published online in JACC Cardiovascular Interventions with an accompanying editorial by David E. Kandzari, MD, director of interventional cardiology, Piedmont Hart Institute, Atlanta.

Commenting on the large pile of meta-analyses, sometimes published months apart, Dr. Kandzari explained that their “short half-life” is a product of the continuous updating of data with new trials. For a procedure that remains controversial, he said these constant relooks are inevitable.

“My point is that, with more studies, we can expect to see more meta-analyses. It is just the way this is going to work,” Dr. Kandzari said in an interview.
 

Individual study data also relevant

Even as the authors of these analyses attempt to cull the best data from the most rigorously performed trials, “we are also going to have to look at the individual studies, because of the differences in the trial designs, particularly the devices used,” according to Dr. Kandzari, who was the principle investigator of the sham-controlled SPYRAL HTN-ON MED trial.

So far, the data, despite some inconsistencies, have supported “clinically meaningful” BP reductions and acceptable safety regardless of the device used, according to Dr. Kandzari. Although he also agrees with the basic premise that more long-term data are needed to better determine how renal denervation should be applied in management of hypertension, he does think it will eventually find a role that is “complimentary to, rather than a replacement for, drugs.”

“The effect is modest, but keep in mind that the effect size is similar to that of a single oral medication, and there are some features, such as an always-on 24-hour effect that could be useful,” he said.

“We have enough of a signal to start thinking of how this will be enveloped into routine care,” he said.

But it is not ready yet. This was the point made by Dr. Ahmad, and it was seconded by Dr. Kandzari. One of the senior authors of the meta-analysis, Deepak Bhatt, MD, executive director of interventional cardiovascular programs, Brigham and Women’s Health, Boston, was also asked to weigh on when it will be ready for prime time.

“At a minimum, I would recommend completion of ongoing sham-controlled randomized trials before considering clinical use of renal denervation. Longer term safety and durability data, as well as data on cost-effectiveness, are all still needed – preferably from randomized trials as opposed to registries,” he said.

“Ideally, larger sham-controlled trials with longer follow-up and clinical endpoints, as opposed to only blood pressure measurements, would be performed, although I am not aware of any plans at present,” he added.

Dr. Ahmad reported no financial relationships relevant to this research. Dr. Bhatt has financial relationships with more than 30 pharmaceutical companies, including those developing products relevant to hypertension and renal denervation. Dr. Kandzari reported financial relationships with Ablative Solutions and Medtronic.

Researchers writing in the British Journal of Dermatology confirm the long-term use of hydrochlorothiazide is associated with a dose-dependent, twofold increased risk of squamous cell carcinoma, compared with calcium channel blocker use.

The findings were originally reported in two Danish case-control studies in which physicians reported a fourfold increased risk of squamous cell carcinoma, and a moderate increased risk of basal cell carcinoma and cutaneous malignant melanoma in patients who used hydrochlorothiazide long-term.

And, while the new study did not find an increased risk of basal cell carcinoma and cutaneous malignant melanoma among long-term users of hydrochlorothiazide, they suggest that bendroflumethiazide “may be a safer alternative for patients at increased risk of skin cancer.” The long-term use of indapamide was associated with a moderately increased risk of cutaneous malignant melanoma but did not alter the risk of either squamous cell or basal cell carcinoma

“Our results suggest that bendroflumethiazide may be a safer alternative to hydrochlorothiazide and indapamide, especially for patients at increased risk of skin cancer, but future studies are needed to rule out a causal association between bendroflumethiazide and cutaneous malignant melanoma,” wrote authors who were led by Christoph R. Meier, PhD, a professor in pharmacy with University Hospital Basel (Switzerland) and a contributor to the Boston Collaborative Drug Surveillance Program.

This study adds to existing evidence that there is a dose-dependent increased risk of squamous cell carcinoma in users of high cumulative doses of hydrochlorothiazide, compared with non–hydrochlorothiazide users.

The study, an observational cohort study, was published earlier this year. It is based on data from the U.K.-based Clinical Practice Research Datalink. It included 271,154 new users of thiazides and thiazidelike diuretics, the majority at 87.6% having been prescribed bendroflumethiazide, 5.8% indapamide, and 3.6% hydrochlorothiazide. Outcomes were compared to those observed in 275,263 users of calcium channel blockers.

“The three primary outcomes of interest were a first-time diagnosis of cutaneous malignant melanoma, basal cell carcinoma, or squamous cell carcinoma,” the authors wrote.

Incidence rates and incidence rate ratios were estimated for both short-term and long-term users of thiazidelike diuretics and calcium channel blockers, while a propensity score (PS) analysis was done in order to control for 23 baseline covariates. The mean follow-up after PS weighting was 3.9 years for indapamide users and 5.5 years for hydrochlorothiazide users. Overall, the incidence rate ratios of squamous cell carcinoma were not markedly increased for either short-term or long-term users of thiazidelike diuretics, the authors reported.

In contrast, the incidence rate ratios of squamous cell carcinoma for hydrochlorothiazide users were increased by 29% for short-term users at an IRR of 1.29 while they were increased by almost twofold for long-term hydrochlorothiazide users at an IRR of 1.95.

Long-term use of hydrochlorothiazide was again associated with a 64% increased risk of basal cell carcinoma, compared with users of a renin-angiotensin inhibitor at a weighted IRR of 1.64.

In contrast, weighted incident rate ratios for basal cell carcinoma for both short-term and long-term thiazide users were not significantly different and results were similar for patients who took hydrochlorothiazide, indapamide, or bendroflumethiazide.

Weighted overall incident rate ratios for cutaneous malignant melanoma were not significantly different for either short-term or long-term users of thiazidelike diuretics, compared with calcium channel blocker users.

However, there was a 43% increased risk of cutaneous malignant melanoma among long-term indapamide users at a weighted IRR of 1.43, compared with calcium channel blocker users, the authors reported.

“Given the biological plausibility and the severe clinical implications of cutaneous malignant melanoma, this finding should be considered carefully,” they cautioned.

Limitations to the study include the fact that the database analyzed does not have information on sun exposure, skin characteristics, or socioeconomic status which may affect the amount of sun exposure participants received.

The authors had no conflicts of interest to declare.

Women who had a preterm delivery were at least 1.6 times as likely to develop hypertension over the next decade as those who had full-term deliveries, based on data from a national cohort study of more than 2 million women.

Pregnancy complications such as preeclampsia and other hypertensive disorders of pregnancy have been associated with chronic hypertension as well as with preterm delivery, but the independent role of preterm delivery in chronic hypertension risk remains unclear, Casey Crump, MD, of the Icahn School of Medicine at Mount Sinai, New York, and colleagues wrote. “A better understanding of the long-term hypertension risks associated with preterm delivery is needed to improve risk stratification, clinical monitoring, and CVD [cardiovascular disease] prevention in women.”

In a study published in JAMA Cardiology, the researchers reviewed data from 2,195,989 women with 4,308,286 singleton deliveries in Sweden from Jan. 1, 1973, to Dec. 31, 2015. Women with preexisting hypertension before their first pregnancy were excluded. Pregnancy duration was based on maternal reports of the last menstrual period for patients in the 1970s, and based on ultrasound estimates in the 1980s and beyond. Pregnancy duration was divided into six groups in terms of completed weeks of gestation: extremely preterm (22-27 weeks), moderately preterm (28-33 weeks), late preterm (34-36 weeks), early term (37-38 weeks), full term (39-41 weeks), and post term (≥42 weeks). Full-term delivery was used as the reference, and the three preterm groups were combined for summaries of preterm delivery (less than 37 weeks).

Overall, women who delivered at less than 37 weeks’ gestation had a 1.6-fold increased risk of hypertension (adjusted hazard ratio, 1.67) within the next 10 years, compared with women who delivered full term after controlling for preeclampsia, other hypertensive disorders of pregnancy, and maternal factors.

When further stratified by pregnancy duration, the aHRs for extremely preterm, moderately preterm, late preterm, and early term, compared with full-term deliveries were 2.23, 1.85, 1.55, and 1.26, respectively, in the first decade after delivery. Each additional week of pregnancy was associated with a mean 7% reduction in hypertension risk (a HR, 0.93).

The increased hypertension risk following preterm delivery (less than 37 weeks) persisted at 10-19 years, 20-29 years, and 30-43 years, with aHRs of 1.40, 1.20, and 1.12, respectively. Early-term delivery at 37-38 weeks also carried an increased risk of long-term hypertension compared with full-term delivery, with aHRs of 1.12 and 1.06 at 20-29 years and 30-43 years, respectively.

“Cosibling analyses suggested that these findings were only partially explained by familial (genetic and/or early-life environmental) factors that are shared determinants of both preterm delivery and hypertension,” the researchers noted. The findings suggest that preterm delivery itself may contribute to or affect the pathophysiology that leads to cardiovascular disease, they added, hypothesizing that endothelial dysfunction caused by preterm delivery may cause functional impairments in the microvasculature.

The study findings were limited by several factors including the lack of detailed records to verify hypertension and the use of data from a single country, the researchers noted. However, the results were strengthened by the large study population, the use of highly complete prenatal and birth records to minimize selection bias, and the long-term follow-up.

The results are consistent with those from previous studies, and support the recognition of preterm delivery as a lifetime risk factor for hypertension, but future studies should focus on racial and ethnic subgroups already at increased risk for both preterm delivery and hypertension, they added.

“Additional follow-up will be needed to examine these associations in older adulthood when hypertension increasingly and disproportionately affects women,” they concluded.

Data highlight the need for patient and provider education

“This study furthers our knowledge regarding long-term complications associated with the frequent pregnancy complication of preterm delivery,” Stephen S. Crane, MD, an ob.gyn. and maternal-fetal medicine specialist in private practice in Orlando, said in an interview. “Cardiovascular disease is the leading cause of death and often goes unrecognized in women. There are shared risk factors among women and men for developing CVD, the most common being hypertension. However, women have the unique risk factor of pregnancy and its attendant complications including preeclampsia, glucose intolerance, and preterm delivery. Hypertensive disorders in pregnancy often lead to indicated premature delivery, and are associated with development of chronic hypertension and subsequent CVD. However, prior data suggest that preterm delivery itself is a risk factor for developing chronic hypertension later in life.

“The current study, which evaluates one of the most complete population data sets with up to 43 years of follow-up, is the first to assess for familial determinants by cosibling analysis, and supports preterm delivery as an independent risk factor for the development of hypertension,” he said. The study results illustrate that this risk is longstanding, and that recurrent preterm birth further increases the risk of developing hypertension.

Dr. Crane said he was not surprised by the study findings, given that inflammatory processes have been linked to the development of hypertension and CVD. “Similarly, inflammatory processes have been implicated in the pathophysiology of preterm labor and inflammatory cytokines may also play a role in normal term labor. Therefore, it is not surprising that preterm delivery would be a marker for the risk of development of hypertension, as both may be responses to underlying inflammatory processes. Identification of these underlying inflammatory processes and methods for prevention will be critical if we are to decrease both the incidence of preterm birth and CVD.

“As prenatal care may be the only medical care women obtain, it is important to take this opportunity to educate patients regarding their long-term risks of developing hypertension and the need for long-term follow up. Interventions that may help reduce the risk for recurrent preterm birth and long-term risks for developing hypertension and CVD include weight loss, increased activity, and smoking cessation; the resources to achieve these goals need to be shared with patients,” he said.

“Knowledge deficits both on the part of the provider and patient may be a significant barrier to intervention that may be overcome with improved education,” said Dr. Crane. “Care providers need education regarding the long-term risks associated with a history of preterm delivery in order to better educate their patients regarding both prevention of recurrent preterm birth and the development of hypertension and CVD.” However, socioeconomic status, education level, and the inability to obtain further health care remain common barriers to intervention for many women.

“Additional research is needed to identify the causes of inflammatory processes leading to preterm delivery and risks for hypertension and CVD,” said Dr. Crane. “Only after the causes are identified can treatments be sought to successfully treat these conditions.”

The study was supported by the National Heart, Lung, and Blood Institute at the National Institutes of Health; the Swedish Research Council; the Swedish Heart-Lung Foundation; and an Avtal om Läkarutbildning och Forskning (Agreement on Medical Training and Research) (ALF) project grant from Region Skåne/Lund University. Neither the researchers nor Dr. Crane had any financial conflicts to disclose.

Data highlight the need for patient and provider education

“This study furthers our knowledge regarding long-term complications associated with the frequent pregnancy complication of preterm delivery,” Stephen S. Crane, MD, an ob.gyn. and maternal-fetal medicine specialist in private practice in Orlando, said in an interview. “Cardiovascular disease is the leading cause of death and often goes unrecognized in women. There are shared risk factors among women and men for developing CVD, the most common being hypertension. However, women have the unique risk factor of pregnancy and its attendant complications including preeclampsia, glucose intolerance, and preterm delivery. Hypertensive disorders in pregnancy often lead to indicated premature delivery, and are associated with development of chronic hypertension and subsequent CVD. However, prior data suggest that preterm delivery itself is a risk factor for developing chronic hypertension later in life.

“The current study, which evaluates one of the most complete population data sets with up to 43 years of follow-up, is the first to assess for familial determinants by cosibling analysis, and supports preterm delivery as an independent risk factor for the development of hypertension,” he said. The study results illustrate that this risk is longstanding, and that recurrent preterm birth further increases the risk of developing hypertension.

Dr. Crane said he was not surprised by the study findings, given that inflammatory processes have been linked to the development of hypertension and CVD. “Similarly, inflammatory processes have been implicated in the pathophysiology of preterm labor and inflammatory cytokines may also play a role in normal term labor. Therefore, it is not surprising that preterm delivery would be a marker for the risk of development of hypertension, as both may be responses to underlying inflammatory processes. Identification of these underlying inflammatory processes and methods for prevention will be critical if we are to decrease both the incidence of preterm birth and CVD.

“As prenatal care may be the only medical care women obtain, it is important to take this opportunity to educate patients regarding their long-term risks of developing hypertension and the need for long-term follow up. Interventions that may help reduce the risk for recurrent preterm birth and long-term risks for developing hypertension and CVD include weight loss, increased activity, and smoking cessation; the resources to achieve these goals need to be shared with patients,” he said.

“Knowledge deficits both on the part of the provider and patient may be a significant barrier to intervention that may be overcome with improved education,” said Dr. Crane. “Care providers need education regarding the long-term risks associated with a history of preterm delivery in order to better educate their patients regarding both prevention of recurrent preterm birth and the development of hypertension and CVD.” However, socioeconomic status, education level, and the inability to obtain further health care remain common barriers to intervention for many women.

“Additional research is needed to identify the causes of inflammatory processes leading to preterm delivery and risks for hypertension and CVD,” said Dr. Crane. “Only after the causes are identified can treatments be sought to successfully treat these conditions.”

The study was supported by the National Heart, Lung, and Blood Institute at the National Institutes of Health; the Swedish Research Council; the Swedish Heart-Lung Foundation; and an Avtal om Läkarutbildning och Forskning (Agreement on Medical Training and Research) (ALF) project grant from Region Skåne/Lund University. Neither the researchers nor Dr. Crane had any financial conflicts to disclose.

Lupin Pharmaceuticals is recalling all batches of irbesartan tablets USP 75 mg, 150 mg, and 300 mg and irbesartan and hydrochlorothiazide (HCTZ) tablets USP 150 mg/12.5 mg and 300 mg/12.5 mg because of the potential presence of the N-nitrosoirbesartan impurity.

“As part of Lupin’s ongoing assessment, analysis revealed that certain tested active pharmaceutical ingredient (API) batches (but not finished product batches) were above the specification limit for the impurity, N-nitrosoirbesartan,” the company said in a news release posted on the U.S. Food and Drug Administration’s website. It notes that the impurity is a “probable human carcinogen.”

Lupin discontinued the marketing of irbesartan and irbesartan/HCTZ tablets on Jan. 7, 2021. It says it “has received no reports of illness that appear to relate to this issue” and is issuing the recall out of “an abundance of caution.”

The company, however, goes on to note that from Oct. 8, 2018 (the earliest date of shipment from the manufacturing site of any of the affected batches) to September 30 of this year, Lupin received four reports of illness from irbesartan and 0 reports from irbesartan/HCTZ.

Irbesartan is an angiotensin II receptor blocker indicated for treatment of hypertension in patients with type 2 diabetes, elevated serum creatinine, and proteinuria.

Irbesartan/HCTZ tablets include irbesartan and hydrochlorothiazide, a thiazide diuretic, indicated for hypertension in patients not adequately controlled with monotherapy or as an initial therapy in patients likely to need multiple drugs to achieve blood pressure goals.

Lupin is notifying wholesalers, distributors, and retail outlets to immediately discontinue sales of the affected product lots and return them to the company. Specific lot numbers can be found here.

The company is advising patients to continue taking their medication and to contact their pharmacist, physician, or health care professional for advice regarding an alternative treatment.

Patients and physicians are also advised to report any adverse events or side effects related to the affected products to MedWatch, the U.S. Food and Drug Administration’s Safety Information and Adverse Event Reporting program.

New risk equations can help determine the need for a first coronary artery calcium (CAC) scan in young adults to identify those most at risk for premature atherosclerosis, researchers say.

“To our knowledge this is the first time to derive a clinical risk equation for the initial conversion from CAC 0, which can be used actually to guide the timing of CAC testing in young adults,” Omar Dzaye, MD, MPH, PhD, Johns Hopkins University School of Medicine, Baltimore, said in an interview.

CAC is an independent predictor of adverse atherosclerotic cardiovascular disease (ASCVD), but routine screening is not recommended in low-risk groups. U.S. guidelines say CAC testing may be considered (class IIa) for risk stratification in adults 40 to 75 years at intermediate risk (estimated 10-year ASCVD risk 7.5% to 20%) when the decision to start preventive therapies is unclear.

The new sex-specific risk equations were derived from 22,346 adults 30 to 50 years of age who underwent CAC testing between 1991 and 2010 for ASCVD risk prediction at four high-volume centers in the CAC Consortium. The average age was 43.5 years, 25% were women, and 12.3% were non-White.

The participants were free of clinical ASCVD or CV symptoms at the time of scanning but had underlying traditional ASCVD risk factors (dyslipidemia in 49.6%, hypertension in 20.0%, active smokers 11.0%, and diabetes in 4.0%), an intermediate 10-year ASCVD risk (2.6%), and/or a significant family history of CHD (49.3%).

As reported in the Journal of the American College of Cardiology, 92.7% of participants had a low 10-year ASCVD risk below 5%, but 34.4% had CAC scores above 0 (median, 20 Agatston units).

Assuming a 25% testing yield (number needed to scan equals four to detect one CAC score above 0), the optimal age for a first scan in young men without risk factors was 42.3 years, and for women it was 57.6 years.

Young adults with one or more risk factors, however, would convert to CAC above 0 at least 3.3 years earlier on average. Diabetes had the strongest influence on the probability of conversion, with men and women predicted to develop incident CAC a respective 5.5 years and 7.3 years earlier on average.

The findings build on previous observations by the team showing that diabetes confers a 40% reduction in the so-called “warranty period” of a CAC score of 0, Dr. Dzaye noted. The National Lipid Association 2020 statement on CAC scoring also suggests it’s reasonable to obtain a CAC scan in people with diabetes aged 30 to 39 years.

“The predicted utility of CAC for ASCVD outcomes is similar in type 1 and type 2 diabetes; however, individuals with type 1 diabetes may actually develop CAC as young as 17 years of age,” he said. “Therefore, definitely, CAC studies in this population are required.”

In contrast, hypertension, dyslipidemia, active smoking, and a family history of CHD were individually associated with the development of CAC 3.3 to 4.3 years earlier. In general, the time to premature CAC was longer for women than for men with a given risk-factor profile.

The predicted age for a first CAC was 37.5 years for men and 48.9 years for women with an intermediate risk-factor profile (for example, smoking plus hypertension) and 33.8 years and 44.7 years, respectively, for those with a high-risk profile (for example, diabetes plus dyslipidemia).

Asked whether the risk equations can be used to guide CAC scanning in clinical practice, Dr. Dzaye said, “we very much believe that this can be used because for the process we published the internal validation, and we also did an external validation that is not published at the moment in [the] MESA [trial].”

He pointed out that study participants did not have a second CAC scan for true modeling of longitudinal CAC and do not represent the general population but, rather, a general cardiology referral population enriched with ASCVD risk factors. Future studies are needed that incorporate a more diverse population, multiple CAC scans, and genetic risk factors.

“This is helpful from a descriptive, epidemiologic point of view and helps us understand the approximate prevalence of coronary calcium greater than 0 in younger men and women, but I’m not convinced that it will or should change clinical practice,” cardiologist Philip Greenland, MD, a professor of preventive medicine and professor of medicine at Northwestern University in Chicago, said in an interview.

Dr. Greenland, who coauthored a review on CAC testing earlier this month, said CAC is the strongest tool we have to improve risk prediction beyond standard risk scores but does involve radiation exposure and some added costs. CAC testing is especially useful as a tiebreaker in older intermediate-risk patients who may be on the fence about starting primary prevention medications but could fall short among “younger, low-risk patients where, as they show here, the proportion of people who have a positive test is well below half.”

“So that means you’re going to have a very large number of people who are CAC 0, which is what we would expect in relatively younger people, but I wouldn’t be happy to try to explain that to a patient: ‘We’re not seeing coronary atherosclerosis right now, but we still want to treat your risk factors.’ That’s kind of a dissonant message,” Dr. Greenland said.

An accompanying editorial suggests “the study has filled an important clinical gap, providing highly actionable data that could help guide clinical decision making for ASCVD prevention.”

Nevertheless, Tasneem Naqvi, MD, Mayo Clinic, Scottsdale, Arizona, and Tamar Polonsky, MD, University of Chicago, question the generalizability of the results and point out that CAC screening at the authors’ recommended ages “could still miss a substantial number of young women with incident MI.”

Exposure to ionizing radiation with CAC is lower than that used in screening mammography for breast cancer but, they agree, should be considered, particularly in young women.

“Alternatively, ultrasonography avoids radiation altogether and can detect plaque earlier than the development of CAC,” write Dr. Naqvi and Dr. Polonsky. Further, the 2019 European Society of Cardiology guidelines for CV risk give ultrasound assessment of carotid artery and femoral plaque a class IIa recommendation and CAC a class IIb recommendation.

Commenting for this news organization, Roger Blumenthal, MD, director of the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease, said the class IIb recommendation “never really made any sense because the data with coronary calcium is so much stronger than it is with carotid ultrasound.”

“Sometimes smart scientists and researchers differ, but in my strong opinion, the European Society of Cardiology in 2019 did not give it the right classification, while the group I was part of, the American Heart Association/American College of Cardiology [2019 guideline], got it right and emphasized that this is the most cost-effective and useful way to improve risk assessment.”

Dr. Blumenthal, who was not part of the study, noted that U.S. guidelines say CAC measurement is not intended as a screening test for everyone but may be used selectively as a decision aid.

“This study adds to the information about how to use that type of testing. So, I personally think it will be a highly referenced article in the next set of guidelines that the American Heart Association, American College of Cardiology, and other organizations have.”

The study was supported in part by a research grant from the National Institutes of Health National Heart, Lung, and Blood Institute. Dr. Dzaye, Dr. Blumenthal, Dr. Naqvi, and Dr. Polonsky report having no relevant financial relationships.

The Food and Drug Administration has issued voluntary, short-term sodium reduction targets for food manufacturers, chain restaurants, and food service operators for processed, packaged, and prepared foods, with an eye toward reducing diet-related conditions such as heart disease and obesity.

According to the FDA, more than 70% of total sodium intake is from sodium added during food manufacturing and commercial food preparation.

The new targets seek to decrease average sodium intake from approximately 3,400 mg/day to 3,000 mg/day, about a 12% reduction, over the next 2.5 years, acting FDA Commissioner Janet Woodcock, MD, and Susan Mayne, PhD, director of the FDA’s Center for Food Safety and Applied Nutrition, said in joint statement.

Although this reduction keeps the average intake above the recommended limit of 2,300 mg/day for individuals 14 years and older as per the Dietary Guidelines for Americans, “we know that even these modest reductions made slowly over the next few years will substantially decrease diet-related diseases,” they added.

The FDA first proposed recommendations for reducing sodium content in draft guidance released in 2016.

Since, then a number of companies in the food industry have already made changes to sodium content in their products, “which is encouraging, but additional support across all types of foods to help consumers meet recommended sodium limits is needed,” Dr. Woodcock and Dr. Mayne said.

They emphasized that the new guidance represents short-term goals that the food industry should work to meet as soon as possible to help optimize public health.

“We will continue our discussions with the food industry as we monitor the sodium content of the food supply to evaluate progress. In the future, we plan to issue revised, subsequent targets to further lower the sodium content incrementally and continue to help reduce sodium intake,” Dr. Woodcock and Dr. Mayne said.
 

AHA: A good first step that does not go far enough

In a statement, the American Heart Association said the new targets will play “a critical role in helping people across the country achieve healthier levels of sodium and improved well-being overall. These targets will be an important driver to reduce sodium consumption, which can have significant health benefits and lead to lower medical costs.”

“Lowering sodium levels in the food supply would reduce risk of hypertension, heart disease, stroke, heart attack, and death in addition to saving billions of dollars in health care costs over the next decade,” the AHA said.

But the AHA also said lowering sodium intake to 3,000 mg/day is not enough.

“Lowering sodium further to 2,300 mg could prevent an estimated 450,000 cases of cardiovascular disease, gain 2 million quality-adjusted life-years, and save approximately $40 billion in health care costs over a 20-year period,” the AHA said.

The AHA is urging the FDA to “follow [this] action with additional targets to further lower the amount of sodium in the food supply and help people in America attain an appropriate sodium intake.”

The Food and Drug Administration has issued voluntary, short-term sodium reduction targets for food manufacturers, chain restaurants, and food service operators for processed, packaged, and prepared foods, with an eye toward reducing diet-related conditions such as heart disease and obesity.

According to the FDA, more than 70% of total sodium intake is from sodium added during food manufacturing and commercial food preparation.

The new targets seek to decrease average sodium intake from approximately 3,400 mg/day to 3,000 mg/day, about a 12% reduction, over the next 2.5 years, acting FDA Commissioner Janet Woodcock, MD, and Susan Mayne, PhD, director of the FDA’s Center for Food Safety and Applied Nutrition, said in joint statement.

Although this reduction keeps the average intake above the recommended limit of 2,300 mg/day for individuals 14 years and older as per the Dietary Guidelines for Americans, “we know that even these modest reductions made slowly over the next few years will substantially decrease diet-related diseases,” they added.

The FDA first proposed recommendations for reducing sodium content in draft guidance released in 2016.

Since, then a number of companies in the food industry have already made changes to sodium content in their products, “which is encouraging, but additional support across all types of foods to help consumers meet recommended sodium limits is needed,” Dr. Woodcock and Dr. Mayne said.

They emphasized that the new guidance represents short-term goals that the food industry should work to meet as soon as possible to help optimize public health.

The rapid transition to and reliance on telehealth to manage patients with heart failure during the COVID-19 pandemic does not appear to impact clinical outcomes, according to real-world data.

HF outpatients managed with telehealth visits did not show a significantly higher adjusted risk for subsequent ED visits, hospital admissions, intensive care use, or death at 30 and 90 days, the investigators reported in JACC: Heart Failure.

“Telehealth is safe and effective in probably some of our highest-risk patients who traditionally have needed hands-on, in-person assessment and evaluation – those patients who have heart failure – so we shouldn’t be afraid to use it all the time, not when needed as a minimum,” senior author Brett W. Sperry, MD, said in an interview.

Heart failure is a perfect case example to examine telehealth because the chronic condition not only requires continual assessment and medication adjustments, but HF patients are also particularly vulnerable to complications related to COVID-19 infection, he noted. A small, single-center report on telehealth early in Italy’s outbreak showed fewer HF hospitalizations and similar mortality, compared with in-person visits in 2019 but, overall, few data exist.

The current analysis took a wider sweep, comparing HF patients seen from March 15 to June 15, 2020 with those seen during the same time period in 2018 and 2019 at 16 cardiology clinics in Saint Luke’s Health System, which serves the Kansas City metro area and surrounding suburbs in Missouri and Kansas.

Among 8,263 unique patients and 15,421 visits identified, telehealth was not used in 2018 or 2019 but accounted for 88.5% of visits during the study period in 2020, 70% of which were by telephone and 30% of which were by video.

“We had zero telehealth before March 2020 and basically built an entire telehealth apparatus in a week or 2,” explained Dr. Sperry. “Initially it was a lot of telephone visits while we were getting the video stuff figured out, which is reflected in the paper, and then went to mostly video visits.”

Despite the pandemic, however, more outpatients were seen in 2020 than in 2018 and 2019 (4,063 vs. 3675 and 3,619 patients, respectively). This likely reflects the shift of personnel and resources from hospital duties to outpatient virtual visits, which were strongly recommended by the Heart Failure Society of America and other professional societies to manage patients during the pandemic, he said.

Unadjusted analyses demonstrated fewer ED visits and hospital admissions and more ICU admissions and all-cause mortality in 2020 than in previous years.

A propensity-matched analysis involving 4541 pairs of patients, however, showed admissions to the ED or hospital were lower after the telehealth visits than after in-person visits at 30 days (6.8% vs 10.4%; P < .001) and 90 days (17.9% vs. 23.3%; P < .001).

Among hospitalized patients, there was no difference between telehealth and in-patient visits in ICU admissions at 30 or 90 days. Mortality was also similar at 30 days (0.8% vs. 0.7%; P = .465) and 90 days (2.9% vs. 2.4%; P = .133).

Dr. Sperry said the pendulum has swung since 2020 and that the team is back to seeing most people in person, with about 15% of his clinic visits that day done via video. Standardized quality of life assessments prior to outpatient visits can help triage patients to telehealth in-patient visits, but in-person visits will still be needed for cases with greater acuity, older patients, and those with limited or no access to quality telephone videos or the internet.

“It isn’t for everyone,” Dr. Sperry said. “You’re going to need some kind of hybrid model with both in-person and video visits available and be able to offer both for patients and be able to titrate that as the pandemic changes in the future.”

Ankit Bhatia, MD, an advanced HF cardiologist at Christ Hospital in Cincinnati, who was not part of the study, said in an interview the use of telehealth in 85% of patients may be higher than the norm at most centers but that the study provides much-needed data.

“I’m really appreciative of a study like this because we were all in such a rush last year to get patients seen that very few people thought how could we design a study to really ensure we’re treating our patients within an equipoise with prior practices,” he said.

“The fact that they were able to do that [85%] and demonstrate in a propensity-matched analysis that outcomes were similar really just shows that telehealth is a strategy that we can use well in patients with heart failure to extend our ability to take care of them,” said Dr. Bhatia, a member of the American College of Cardiology Health Care Innovation Council.

Even beyond the pandemic, he said, the trend in health care is for patients to want health care delivered closer to home and for health care systems to become more patient centric. “This accelerated that but what I think this study showed me was that it’s okay to have this be part of my care model and I’m not sacrificing on my patient care if I choose to intersperse telehealth with inpatient visits.”

Besides the inherent limitations of retrospective studies, the authors noted that diagnoses in the study were based on ICD-10 codes and that subsequent ED visits or hospitalizations outside the single system may have been underreported. A further limitation is that they could not identify the cause of death or reasons for hospital encounters.

“Further data are needed to confirm the relative safety of a telehealth strategy in the HF population over a more sustained period of time, although we hypothesize that greater risks would be observed early after telehealth visits, where patients’ acuity might be misjudged,” they wrote.
