Active older women show heightened AFib risk
Older women with high levels of physical activity showed twice the risk of atrial fibrillation (AFib) over 10 years as they did for cardiac disease or stroke, based on data from 46 cross-country skiers.
Although previous research suggests that women derive greater health benefits from endurance sports, compared with men, women are generally underrepresented in sports cardiology research, and most previous studies have focused on younger women, Marius Myrstad, MD, of Baerum Hospital, Gjettum, Norway, said in a presentation at the annual congress of the European Association of Preventive Cardiology.
Previous research also has shown an increased risk of AFib in male endurance athletes, but similar data on women are lacking, Dr. Myrstad said.
The researchers reviewed data from the Birkebeiner Ageing Study, a study of Norwegian cross-country skiers aged 65 years and older who were followed for 10 years. The participants were competitors in the 2009/2010 Birkebeiner race, a 54-km cross country ski race in Norway.
Participants responded to a questionnaire addressing cardiovascular disease risk factors, exercise habits, and other health issues. The mean age at baseline was 67.5 year. A total of 34 participants (76%) were available for follow-up visits in 2014, and 36 attended a follow-up visit in 2020. Cumulative exposure to exercise was 26 years.
A total of 86% of the women reported moderate to vigorous exercise in the past year at baseline; 61% did so at the 2020 follow-up visit. One of the participants died during the study period.
“The baseline prevalence of cardiovascular conditions was very low,” Dr. Myrstad noted.
However, despite a low prevalence of cardiovascular risk factors, the risk of AFib in the study population was twice as high as for other cardiac diseases and stroke (15.6%, 7.1%, and 7.1%, respectively).
The mechanism of action for the increased AFib remains unclear, but the current study highlights the need for large, prospective studies of female athletes to address not only AFib, but also exercise-induced cardiac remodeling and cardiovascular health in general, said Dr. Myrstad.
The findings were limited by the small sample size and use of self-reports, Dr. Myrstad said, and more research is needed to clarify the association between increased AFib and high-level athletic activity in women.
“We should strive to close the gap between female and male athletes in sports cardiology research,” he added.
Consider the big picture of AFib risk
This study is important because of the growing recognition that atrial fibrillation may be a preventable disease, said Gregory Marcus, MD, a cardiologist at the University of California, San Francisco, said in an interview.
“Various behaviors or exposures that are under the control of the individual patient may reveal especially powerful means to help reduce risk,” he added.
Dr. Marcus said he was not surprised by the current study findings, as they reflect those of other studies suggesting a heightened risk for atrial fibrillation associated with very excessive exercise. However, the study was limited by the relatively small size and lack of a comparison group, he said. In addition, “The study was observational, and therefore the possibility that factors other than the predictor of interest, in this case intensive endurance exercise, were truly causal of atrial fibrillation could not be excluded,” he noted.
“It is very important to place this specialized analysis in the greater context of the full weight of evidence related to physical activity and atrial fibrillation,” said Dr. Marcus. “Specifically, when it comes to the general public and the great majority of patients we see in clinical practice, encouraging more physical activity is generally the best approach to reduce risks of atrial fibrillation,” he said. “It appears to be only in extraordinarily rigorous and prolonged endurance exercise that higher risks of atrial fibrillation may result,” he noted.
However, “Exercise also has many other benefits, related to overall cardiovascular health, brain health, bone health, and even cancer risk reduction, such that, even among the highly trained endurance athletes, the net benefit versus risk remains unknown,” he said.
“While the risk of atrial fibrillation in these highly trained endurance athletes was higher than expected, it still occurred in the minority,” Dr. Marcus said. “Therefore, there are certainly other factors yet to be identified that influence this heightened atrial fibrillation risk, and future research aimed at elucidating these other factors may help identify individuals more or less prone to atrial fibrillation or other behaviors that can help mitigate that risk.”
Dr. Myrstad disclosed lecture fees from Bayer, Boehringer-Ingelheim, Bristol Myers Squibb, MSD, and Pfizer unrelated to the current study. Dr. Marcus disclosed serving as a consultant for Johnson and Johnson and InCarda, and holding equity as a cofounder of InCarda.

10 popular diets for heart health ranked
An evidence-based analysis of 10 popular dietary patterns shows that some promote heart health better than others.
A new American Heart Association scientific statement concludes that the Mediterranean, Dietary Approach to Stop Hypertension (DASH), pescatarian, and vegetarian eating patterns most strongly align with heart-healthy eating guidelines issued by the AHA in 2021, whereas the popular paleolithic (paleo) and ketogenic (keto) diets fall short.
“The good news for the public and their clinicians is that there are several dietary patterns that allow for substantial flexibility for following a heart healthy diet – DASH, Mediterranean, vegetarian,” writing-group chair Christopher Gardner, PhD, with Stanford (Calif.) University, told this news organization.
“However, some of the popular diets – particularly paleo and keto – are so strictly restrictive of specific food groups that when these diets are followed as intended by their proponents, they are not aligned with the scientific evidence for a heart-healthy diet,” Dr. Gardner said.
The statement was published online in Circulation.
A tool for clinicians
“The number of different, popular dietary patterns has proliferated in recent years, and the amount of misinformation about them on social media has reached critical levels,” Dr. Gardner said in a news release.
“The public – and even many health care professionals – may rightfully be confused about heart-healthy eating, and they may feel that they don’t have the time or the training to evaluate the different diets. We hope this statement serves as a tool for clinicians and the public to understand which diets promote good cardiometabolic health,” he noted.
The writing group rated on a scale of 1-100 how well 10 popular diets or eating patterns align with AHA dietary advice for heart-healthy eating.
That advice includes consuming a wide variety of fruits and vegetables; choosing mostly whole grains instead of refined grains; using liquid plant oils rather than tropical oils; eating healthy sources of protein, such as from plants, seafood, or lean meats; minimizing added sugars and salt; limiting alcohol; choosing minimally processed foods instead of ultraprocessed foods; and following this guidance wherever food is prepared or consumed.
The 10 diets/dietary patterns were DASH, Mediterranean-style, pescatarian, ovo-lacto vegetarian, vegan, low-fat, very low–fat, low-carbohydrate, paleo, and very low–carbohydrate/keto patterns.
The diets were divided into four tiers on the basis of their scores, which ranged from a low of 31 to a high of 100.
Only the DASH eating plan got a perfect score of 100. This eating pattern is low in salt, added sugar, tropical oil, alcohol, and processed foods and high in nonstarchy vegetables, fruits, whole grains, and legumes. Proteins are mostly plant-based, such as legumes, beans, or nuts, along with fish or seafood, lean poultry and meats, and low-fat or fat-free dairy products.
The Mediterranean eating pattern achieved a slightly lower score of 89 because unlike DASH, it allows for moderate alcohol consumption and does not address added salt.
The other two top tier eating patterns were pescatarian, with a score of 92, and vegetarian, with a score of 86.
“If implemented as intended, the top-tier dietary patterns align best with the American Heart Association’s guidance and may be adapted to respect cultural practices, food preferences and budgets to enable people to always eat this way, for the long term,” Dr. Gardner said in the release.
Vegan and low-fat diets (each with a score of 78) fell into the second tier.
Though these diets emphasize fruits, vegetables, whole grains, legumes, and nuts while limiting alcohol and added sugars, the vegan diet is so restrictive that it could be challenging to follow long-term or when eating out and may increase the risk for vitamin B12 deficiency, which can lead to anemia, the writing group notes.
There also are concerns that low-fat diets treat all fats equally, whereas the AHA guidance calls for replacing saturated fats with healthier fats, they point out.
The third tier includes the very low–fat diet (score 72) and low-carb diet (score 64), whereas the paleo and very low–carb/keto diets fall into the fourth tier, with the lowest scores of 53 and 31, respectively.
Dr. Gardner said that it’s important to note that all 10 diet patterns “share four positive characteristics: more veggies, more whole foods, less added sugars, less refined grains.”
“These are all areas for which Americans have substantial room for improvement, and these are all things that we could work on together. Progress across these aspects would make a large difference in the heart-healthiness of the U.S. diet,” he told this news organization.
This scientific statement was prepared by the volunteer writing group on behalf of the AHA Council on Lifestyle and Cardiometabolic Health, the Council on Cardiovascular and Stroke Nursing, the Council on Hypertension, and the Council on Peripheral Vascular Disease.

AHA backs screening for cognitive impairment after stroke
Screening for cognitive impairment should be part of multidisciplinary care for stroke survivors, the American Heart Association says in a new scientific statement.
“Cognitive impairment after stroke is very common, is associated with other post-stroke outcomes, and often has significant impact on the quality of life,” Nada El Husseini, MD, MHSc, chair of the scientific statement writing group, told this news organization.
“It is important to screen stroke survivors for cognitive impairment as well as for associated comorbidities such as mood and sleep disorders,” said Dr. El Husseini, associate professor of neurology at Duke University Medical Center in Durham, N.C.
The scientific statement was published online in Stroke. It’s the first to specifically focus on the cognitive impairment resulting from an overt stroke (ischemic or hemorrhagic).
‘Actionable’ considerations for care
The writing group performed a “scoping” review of the literature on the prevalence, diagnosis, and management of poststroke cognitive impairment (PSCI) to provide a framework for “actionable considerations” for clinical practice as well as to highlight gaps needing additional studies, Dr. El Husseini explained.
PSCI, ranging from mild to severe, occurs in up to 60% of stroke survivors in the first year after stroke; yet, it is often underreported and underdiagnosed, the writing group notes.
Up to 20% of stroke survivors who experience mild cognitive impairment fully recover cognitive function, and cognitive recovery is most likely within the first 6 months after a stroke.
However, improvement in cognitive impairment without return to prestroke levels is more frequent than is complete recovery. As many as one in three stroke survivors may develop dementia within 5 years of stroke.
The writing group also notes that PSCI is often associated with other conditions, including physical disability, sleep disorders, behavioral and personality changes, depression, and other neuropsychological changes – each of which may contribute to lower quality of life.
Currently, there is no “gold standard” for cognitive screening following stroke, but several brief cognitive screening tests, including the Mini–Mental State Examination and the Montreal Cognitive Assessment, are widely used to identify cognitive impairment after stroke.
The statement also highlights the importance of assessing cognitive changes over time after stroke. Stroke survivors who experience unexplained difficulties with cognitive-related activities of daily living, following care instructions, or providing a reliable health history may be candidates for additional cognitive screening.
Manage risk factors to prevent repeat stroke
“Anticipatory guidance regarding home and driving safety and, return to work (if applicable) along with interdisciplinary collaboration among different medical and ancillary specialists in the diagnosis and management of cognitive impairment is key for the holistic care of stroke survivors,” Dr. El Husseini told this news organization.
The multidisciplinary poststroke health care team could include neurologists, occupational therapists, speech therapists, nurses, neuropsychologists, gerontologists, and primary care providers.
“Because recurrent stroke is strongly associated with the development of cognitive impairment and dementia, prevention of recurrent strokes should be sought to decrease that risk,” Dr. El Husseini said. This includes addressing stroke risk factors, including high blood pressure, high cholesterol, type 2 diabetes, and atrial fibrillation.
The writing group says research is needed in the future to determine how cognitive impairment develops after stroke and the impact of nonbrain factors, including infection, frailty, and social factors.
Further research is also needed to determine best practices for cognitive screening after stroke, including the development and use of screening instruments that consider demographic, cultural, and linguistic factors in determining “normal” function.
“Perhaps the most pressing need, however, is the development of effective and culturally relevant treatments for poststroke cognitive impairment,” Dr. El Husseini said in a news release.
“We hope to see big enough clinical trials that assess various techniques, medications, and lifestyle changes in diverse groups of patients that may help improve cognitive function,” she added.

“Perhaps the most pressing need, however, is the development of effective and culturally relevant treatments for poststroke cognitive impairment,” Dr. El Husseini said in a news release.
“We hope to see big enough clinical trials that assess various techniques, medications, and lifestyle changes in diverse groups of patients that may help improve cognitive function,” she added.
This scientific statement was prepared by the volunteer writing group on behalf of the AHA Stroke Council, the Council on Cardiovascular Radiology and Intervention, the Council on Hypertension, and the Council on Lifestyle and Cardiometabolic Health.
Screening for cognitive impairment should be part of multidisciplinary care for stroke survivors, the American Heart Association says in a new scientific statement.
“Cognitive impairment after stroke is very common, is associated with other post-stroke outcomes, and often has significant impact on the quality of life,” Nada El Husseini, MD, MHSc, chair of the scientific statement writing group, told this news organization.
“It is important to screen stroke survivors for cognitive impairment as well as for associated comorbidities such as mood and sleep disorders,” said Dr. El Husseini, associate professor of neurology at Duke University Medical Center in Durham, N.C.
The scientific statement was published online in Stroke. It’s the first to specifically focus on the cognitive impairment resulting from an overt stroke (ischemic or hemorrhagic).
‘Actionable’ considerations for care
The writing group performed a “scoping” review of the literature on the prevalence, diagnosis, and management of poststroke cognitive impairment (PSCI) to provide a framework for “actionable considerations” for clinical practice as well as to highlight gaps needing additional studies, Dr. El Husseini explained.
PSCI, ranging from mild to severe, occurs in up to 60% of stroke survivors in the first year after stroke; yet, it is often underreported and underdiagnosed, the writing group notes.
Up to 20% of stroke survivors who experience mild cognitive impairment fully recover cognitive function, and cognitive recovery is most likely within the first 6 months after a stroke.
However, improvement in cognitive impairment without return to prestroke levels is more frequent than is complete recovery. As many as one in three stroke survivors may develop dementia within 5 years of stroke.
The writing group also notes that PSCI is often associated with other conditions, including physical disability, sleep disorders, behavioral and personality changes, depression, and other neuropsychological changes – each of which may contribute to lower quality of life.
Currently, there is no “gold standard” for cognitive screening following stroke, but several brief cognitive screening tests, including the Mini–Mental State Examination and the Montreal Cognitive Assessment, are widely used to identify cognitive impairment after stroke.
The statement also highlights the importance of assessing cognitive changes over time after stroke. Stroke survivors who experience unexplained difficulties with cognitive-related activities of daily living, following care instructions, or providing a reliable health history may be candidates for additional cognitive screening.
Manage risk factors to prevent repeat stroke
“Anticipatory guidance regarding home and driving safety and, return to work (if applicable) along with interdisciplinary collaboration among different medical and ancillary specialists in the diagnosis and management of cognitive impairment is key for the holistic care of stroke survivors,” Dr. El Husseini told this news organization.
The multidisciplinary poststroke health care team could include neurologists, occupational therapists, speech therapists, nurses, neuropsychologists, gerontologists, and primary care providers.
“Because recurrent stroke is strongly associated with the development of cognitive impairment and dementia, prevention of recurrent strokes should be sought to decrease that risk,” Dr. El Husseini said. This includes addressing stroke risk factors, including high blood pressure, high cholesterol, type 2 diabetes, and atrial fibrillation.
The writing group says research is needed in the future to determine how cognitive impairment develops after stroke and the impact of nonbrain factors, including infection, frailty, and social factors.
Further research is also needed to determine best practices for cognitive screening after stroke, including the development and use of screening instruments that consider demographic, cultural, and linguistic factors in determining “normal” function.

Step count–heart rate link confirmed in children
, according to a study presented at the Pediatric Academic Societies annual meeting.
The new findings provide a new means for pediatricians to measure physical fitness, the researchers said.
“It really changes the way we evaluate kids’ fitness and gives us a new method of judging physical fitness other than body mass index,” said Susan Gasparino, MD, an instructor in pediatrics at the University of Rochester (N.Y.) Medical Center, who led the study.
Using data from the 2005 to 2006 National Health and Nutrition Examination Survey, Dr. Gasparino and her colleagues examined the association between resting heart rate (RHR) and step count among 899 children and 1,640 adolescents aged 6-19 years.
In the adolescent group, the mean RHR was 74.9 among those who walked more than 10,000 steps per day (n = 414) and 79.3 for those whose step counts fell below that cutoff (n = 1,226) (P < .001). For each additional 1,000 steps per day, RHR decreased by an average of 0.7 beats per minute in this group (P < .001).
In the younger age group, mean RHR was 85.3 among children who took more than 10,000 steps per day (n = 447) and 86.3 among those who did not reach that threshold (n = 452) (P = .29). For each additional 1,000 steps per day, RHR decreased by an average of 0.3 bpm in this group (P = .02)
Dr. Gasparino said next steps in research could include controlling for confounders, such as baseline anxiety and medications that could blunt the heart rate.
Broader implications
If similar results bear out in future studies, monitoring RHR could be incorporated into fitness programs for children and adolescents. Doing so could obviate “the need for intensive treadmill assessments using VO2max, time-consuming and emotionally fraught school-based physical fitness tests, and the fear and potential shame of the scale,” the researchers said.
Dr. Gasparino said measuring RHR during a 3-minute step test could help organizations and governments determine whether fitness programs are improving cardiovascular and overall health and could help them direct “funding and resources to the programs that are effective.” Such a test could also be incorporated into pediatrician wellness checks, she noted.
“It’s an exciting development, and [RHR measurement] holds a lot of promise as a clinical tool that can be applicable in a lot of settings,” said Nicholas M. Edwards, MD, MPH, a sports medicine pediatrician and an associate professor of orthopedics at the University of Minnesota in Minneapolis.
Dr. Edwards said that, because measurement of fitness in clinical settings is difficult, finding ways to “assess fitness in the office with the equipment already at hand would be a superb development.”
If use of RHR to measure fitness “is validated in a clinical setting,” Dr. Edwards said, “I think adoption would be a natural next step.”
Dr. Edwards has disclosed no relevant financial relationships.

Gut microbiome may guide personalized heart failure therapy
Understanding more about the gut microbiome and how it may affect the development and treatment of heart failure could lead to a more personalized approach to managing the condition, a new review article suggests.
the authors note. “Interactions among the gut microbiome, diet, and medications offer potentially innovative modalities for management of patients with heart failure,” they add.
The review was published online in the Journal of the American College of Cardiology.
“Over the past years we have gathered more understanding about how important the gut microbiome is in relation to how our bodies function overall and even though the cardiovascular system and the heart itself may appear to be quite distant from the gut, we know the gut microbiome affects the cardiovascular system and the physiology of heart failure,” lead author Petra Mamic, MD, Stanford (Calif.) University, told this news organization.
“We’ve also learnt that the microbiome is very personalized. It seems to be affected by a lot of intrinsic and as well as extrinsic factors. For cardiovascular diseases in particular, we always knew that diet and lifestyle were part of the environmental risk, and we now believe that the gut microbiome may be one of the factors that mediates that risk,” she said.
“Studies on the gut microbiome are difficult to do and we are right at the beginning of this type of research. But we have learned that the microbiome is altered or dysregulated in many diseases including many cardiovascular diseases, and many of the changes in the microbiome we see in different cardiovascular diseases seem to overlap,” she added.
Dr. Mamic explained that patients with heart failure have a microbiome that appears different and dysregulated, compared with the microbiome in healthy individuals.
“The difficulty is teasing out whether the microbiome changes are causing heart failure or if they are a consequence of the heart failure and all the medications and comorbidities associated with heart failure,” she commented.
Animal studies have shown that many microbial products, small molecules made by the microbiome, seem to affect how the heart recovers from injury, for example after a myocardial infarction, and how much the heart scars and hypertrophies after an injury, Dr. Mamic reported. These microbiome-derived small molecules can also affect blood pressure, which is dysregulated in heart failure.
Other products of the microbiome can be pro-inflammatory or anti-inflammatory, which can again affect the cardiovascular physiology and the heart, she noted.
High-fiber diet may be beneficial
One area of particular interest at present involves the role of short-chain fatty acids, which are a byproduct of microbes in the gut that digest fiber.
“These short chain fatty acids seem to have positive effects on the host physiology. They are anti-inflammatory; they lower blood pressure; and they seem to protect the heart from scarring and hypertrophy after injury. In heart failure, the gut microbes that make these short-chain fatty acids are significantly depleted,” Dr. Mamic explained.
They are an obvious focus of interest because these short-chain fatty acids are produced when gut bacteria break down dietary fiber, raising the possibility of beneficial effects from eating a high-fiber diet.
Another product of the gut microbiome of interest is trimethylamine N-oxide, formed when gut bacteria break down nutrients such as L-carnitine and phosphatidyl choline, nutrients abundant in foods of animal origin, especially red meat. This metabolite has proatherogenic and prothrombotic effects, and negatively affected cardiac remodeling in a mouse heart failure model, the review notes.
However, though it is too early to make specific dietary recommendations based on these findings, Dr. Mamic points out that a high-fiber diet is thought to be beneficial.
“Nutritional research is very hard to do and the data is limited, but as best as we can summarize things, we know that plant-based diets such as the Mediterranean and DASH diets seem to prevent some of the risk factors for the development of heart failure and seem to slow the progression of heart failure,” she added.
One of the major recommendations in these diets is a high intake of fiber, including whole foods, vegetables, fruits, legumes, and nuts, and less intake of processed food and red meat. “In general, I think everyone should eat like that, but I specifically recommend a plant-based diet with a high amount of fiber to my heart failure patients,” Dr. Mamic said.
Large variation in microbiome composition
The review also explores the idea of personalization of diet or specific treatments dependent on an individual’s gut microbiome composition.
Dr. Mamic explains: “When we look at the microbiome composition between individuals, it is very different. There is very little overlap between individuals, even in people who are related. It seems to be more to do with the environment – people who are living together are more likely to have similarities in their microbiome. We are still trying to understand what drives these differences.”
It is thought that these differences may affect the response to a specific diet or medication. Dr. Mamic gives the example of fiber. “Not all bacteria can digest the same types of fiber, so not everyone responds in the same way to a high-fiber diet. That’s probably because of differences in their microbiome.”
Another example is the response to the heart failure drug digoxin, which is metabolized by one particular strain of bacteria in the gut. The toxicity or effectiveness of digoxin seems to be influenced by levels of this bacterial strain, and this again can be influenced by diet, Dr. Mamic says.
Manipulating the microbiome as a therapeutic strategy
Microbiome-targeting therapies may also become part of future treatment strategies for many conditions, including heart failure, the review authors say.
Probiotics (foods and dietary supplements that contain live microbes) interact with the gut microbiota to alter host physiology beneficially. Certain probiotics may specifically modulate processes dysregulated in heart failure, as was suggested in a rodent heart failure model in which supplementation with Lactobacillus-containing and Bifidobacterium-containing probiotics resulted in markedly improved cardiac function, the authors report.
However, a randomized trial (GutHeart) of probiotic yeast Saccharomyces boulardii in patients with heart failure found no improvement in cardiac function, compared with standard care.
Commenting on this, Dr. Mamic suggested that a more specific approach may be needed.
“Some of our preliminary data have shown people who have heart failure have severely depleted Bifidobacteria,” Dr. Mamic said. These bacteria are commercially available as a probiotic, and the researchers are planning a study to give patients with heart failure these specific probiotics. “We are trying to find practical ways forward and to be guided by the data. These people have very little Bifidobacteria, and we know that probiotics seem to be accepted best by the host where there is a specific need for them, so this seems like a sensible approach.”
Dr. Mamic does not recommend that heart failure patients take general probiotic products at present, but she tells her patients about the study she is doing. “Probiotics are quite different from each other. It is a very unregulated market. A general probiotic product may not contain the specific bacteria needed.”
Include microbiome data in biobanks
The review calls for more research on the subject and a more systematic approach to collecting data on the microbiome.
“At present for medical research, blood samples are collected, stored, and analyzed routinely. I think we should also be collecting stool samples in the same way to analyze the microbiome,” Dr. Mamic suggests.
“If we can combine that with data from blood tests on various metabolites/cytokines and look at how the microbiome changes over time or with medication, or with diet, and how the host responds including clinically relevant data, that would be really important. Given how quickly the field is growing I would think there would be biobanks including the microbiome in a few years’ time.”
“We need to gather this data. We would be looking for which bacteria are there, what their functionality is, how it changes over time, with diet or medication, and even whether we can use the microbiome data to predict who will respond to a specific drug.”
Dr. Mamic believes that in the future, analysis of the microbiome could be a routine part of deciding what people eat for good health and to characterize patients for personalized therapies.
“It is clear that the microbiome can influence health, and a dysregulated microbiome negatively affects the host, but there is lot of work to do. We need to learn a lot more about it, but we shouldn’t miss the opportunity to do this,” she concluded.
Dr. Mamic reported no disclosures.

However, a randomized trial (GutHeart) of probiotic yeast Saccharomyces boulardii in patients with heart failure found no improvement in cardiac function, compared with standard care.
Commenting on this, Dr. Mamic suggested that a more specific approach may be needed.
“Some of our preliminary data have shown people who have heart failure have severely depleted Bifidobacteria,” Dr. Mamic said. These bacteria are commercially available as a probiotic, and the researchers are planning a study to give patients with heart failure these specific probiotics. “We are trying to find practical ways forward and to be guided by the data. These people have very little Bifidobacteria, and we know that probiotics seem to be accepted best by the host where there is a specific need for them, so this seems like a sensible approach.”
Dr. Mamic does not recommend that heart failure patients take general probiotic products at present, but she tells her patients about the study she is doing. “Probiotics are quite different from each other. It is a very unregulated market. A general probiotic product may not contain the specific bacteria needed.”
Include microbiome data in biobanks
The review calls for more research on the subject and a more systematic approach to collecting data on the microbiome.
“At present for medical research, blood samples are collected, stored, and analyzed routinely. I think we should also be collecting stool samples in the same way to analyze the microbiome,” Dr. Mamic suggests.
“If we can combine that with data from blood tests on various metabolites/cytokines and look at how the microbiome changes over time or with medication, or with diet, and how the host responds including clinically relevant data, that would be really important. Given how quickly the field is growing I would think there would be biobanks including the microbiome in a few years’ time.”
“We need to gather this data. We would be looking for which bacteria are there, what their functionality is, how it changes over time, with diet or medication, and even whether we can use the microbiome data to predict who will respond to a specific drug.”
Dr. Mamic believes that in the future, analysis of the microbiome could be a routine part of deciding what people eat for good health and to characterize patients for personalized therapies.
“It is clear that the microbiome can influence health, and a dysregulated microbiome negatively affects the host, but there is lot of work to do. We need to learn a lot more about it, but we shouldn’t miss the opportunity to do this,” she concluded.
Dr. Mamic reported no disclosures.

New blood pressure thresholds: How do they affect the evaluation and treatment of hypertension?
In a major shift in the definition of hypertension, guidelines published in 2017 reclassified 130/80 mm Hg as high blood pressure, or stage 1 hypertension. Previous guidelines classified 130/80 mm Hg as elevated, and 140/90 mm Hg used to be the threshold for stage 1 hypertension.
“This shift in classification criteria may cause confusion among clinicians caring for patients with hypertension and has a significant impact on how we diagnose and manage hypertension in our practice,” said Shawna D. Nesbitt, MD, professor of internal medicine at the University of Texas Southwestern Medical Center and medical director at Parkland Hypertension Clinic in Dallas. Dr. Nesbitt is an expert in the diagnosis and treatment of hypertension, particularly complex and refractory cases.
Cardiovascular disease (CVD) is the leading cause of death in the United States, accounting for nearly one-quarter of all deaths in men and in women. Hypertension is a key factor contributing to CVD. The hypertension‐related CVD mortality is currently on the rise in many U.S. demographic groups, including younger individuals (35-64 years old), she said.
When asked about the potential causes of this trend, Dr. Nesbitt explained that the epidemics of obesity and overweight are critical contributors to the high prevalence of hypertension.
The new definition means a wider gap in the prevalence of hypertension between men and women, as well as between Black and White people in the United States. The U.S. rates of hypertension and hypertension‐related CVD mortality are much higher in Black than in White people in this country. Hypertension control rates are the lowest in Black, Hispanic, and Asian males, Dr. Nesbitt said.
Accurate measurement of blood pressure is crucial
The changes in classification criteria for hypertension have made accurate measurements of blood pressure important. A key challenge in the evaluation of hypertension in the clinic is the difference in the methods used to measure blood pressure between trials and real-world clinical practice.
“We can’t easily translate data collected in clinical trials into real-life scenarios, and this can have important implications in our expectations of treatment outcome,” Dr. Nesbitt cautioned.
Commenting on the best practices in blood pressure measurements in the office, Dr. Nesbitt said that patients need to be seated with their feet on the floor and their backs and arms supported. In addition, patients need to have at least 5 minutes of rest without talking.
“It is very important to help patients understand what triggers their blood pressure to be elevated and teach them how and when to measure their blood pressure at home using their own devices,” she added.
Another critical question is how to translate the new guidelines into changes in clinical care, she said.
Current treatment landscape of hypertension
Ensuring a healthy diet, weight, and sleep, participating in physical activity, avoiding nicotine, and managing blood pressure, cholesterol, and sugar levels are the new “Life’s Essential 8” strategies proposed by the American Heart Association (AHA) to reduce CVD risk.
“Sleep has recently been added to the AHA guidelines because it modulates many factors contributing to hypertension,” Dr. Nesbitt pointed out. She advised that clinicians should ask patients about their sleep and educate them on healthy sleeping habits.
Some of the evidence used to develop the new AHA guidelines is derived from the SPRINT trial, which showed that controlling blood pressure reduces the risk of major adverse cardiovascular events. “This is our ultimate goal for our patients with hypertension,” Dr. Nesbitt noted.
Regarding the best practice in hypertension management, Dr. Nesbitt explained that with the new blood pressure thresholds, more patients will be diagnosed with stage 1 hypertension and need the nonpharmacological therapy suggested by the AHA. But patients with stage 1 hypertension and with a high CVD risk (at least 10%) also should receive blood pressure-lowering medications, so an accurate assessment of the risk of clinical atherosclerotic cardiovascular disease (ASCVD) or the estimated 10-year CVD risk is crucial. “If we are not careful, we might miss some patients who need to be treated,” she said.
Calcium channel blockers, thiazide diuretics, and ACE inhibitors or angiotensin receptor blockers (ARBs) are the treatment of choice for patients with newly diagnosed hypertension. Although extensively used in the past, beta-blockers are no longer a first-line treatment for hypertension.
When asked why beta-blockers are no longer suitable for routine initial treatment of hypertension, Dr. Nesbitt said that they are effective in controlling palpitations but “other antihypertensive drugs have proven far better in controlling blood pressure.”
Hypertension is multifactorial and often occurs in combination with other conditions, including diabetes and chronic kidney disease. When developing a treatment plan for patients with hypertension, comorbidities need to be considered, because their management may also help control blood pressure, especially for conditions that may contribute to the development of hypertension.
Common conditions that contribute to and often coexist with hypertension include sleep apnea, obesity, anxiety, and depression. However, convincing people to seek mental health support can be very challenging, Dr. Nesbitt said.
She added that hypertension is a complex disease with a strong social component. Understanding its pathophysiology and social determinants is paramount for successfully managing hypertension at the individual level, as well as at the community level.
Identification and management of side effects is key
Dr. Nesbitt also discussed the importance of the identification and management of side effects associated with blood pressure-lowering drugs. She cautioned that, if not managed, side effects can lead to treatment nonadherence and pseudo‐resistance, both of which can jeopardize the successful management of hypertension.
When asked about her approach to managing side effects and convincing patients to continue taking their medications, Dr. Nesbitt noted that “setting realistic expectations and goals is key.”
In an interview after Dr. Nesbitt’s presentation, Jesica Naanous, MD, agreed that having an honest conversation with the patients is the best way to convince them to keep taking their medications. She also explains to patients that the complications of uncontrolled blood pressure are worse than the side effects of the drugs.
“As a last resort, I change a blood pressure-lowering agent to another,” added Dr. Naanous, an internist at the American British Cowdray (ABC) Medical Center in Mexico City. She explained that many antihypertensive drugs have different toxicity profiles, and simply changing to another agent can make treatment more tolerable for the patient.
Dr. Nesbitt reported no relationships with entities whose primary business is producing, marketing, selling, reselling, or distributing health care products used by or on patients.

Smoking cessation has many benefits in diabetes
MONTPELLIER, FRANCE – The first expert consensus on smoking and diabetes, coauthored by the Francophone Diabetes Society (SFD) and the French Society for the Study of Nicotine Addiction (SFT), was presented at the SFD’s annual conference.
Alexia Rouland, MD, an endocrinologist at Dijon Bourgogne University Hospital, Dijon, France, took the conference as an opportunity to list the many benefits of smoking cessation for patients with diabetes, despite the “slight and temporary” risk for blood sugar imbalance.
Societies target smoking
Diabetes societies around Europe have set their sights on the topic of smoking. Indeed, the guidelines published in 2019 by the European Association for the Study of Diabetes and the European Society of Cardiology state that “smoking cessation is obligatory for all prediabetic and diabetic patients” (class I, level A).
This year, the France-based SFD and SFT dedicated an expert consensus to the major problem of smoking in patients with diabetes. The aim was to provide health care professionals with convincing, well-supported arguments in favor of smoking cessation in their patients with type 1 and type 2 diabetes.
“Before anything else, diabetic patients need to be made aware of the risks of smoking,” said Dr. Rouland. “It’s not just about the fear factor, though. It’s also about providing a positive incentive – they need to be told about the ways they’ll benefit from quitting smoking. For example, you have all-cause mortality, macro- and microangiopathic complications, and so on.”
Duration of abstinence
“Diabetic patients who have stopped smoking have a relative risk for all-cause mortality of 1.28 (1.09-1.51), which is less than what you see in active smokers (relative risk = 1.58; 1.42-1.77), but still above that of nonsmokers,” said Dr. Rouland.
A previous study revealed that although the risk does indeed go down after stopping smoking, it is linked to how long ago the person stopped. Patients who stopped smoking less than 10 years ago still had a slightly raised all-cause mortality risk, and this was even higher if they had smoked for 20 years or more.
After 10 years of not smoking, however, the greater all-cause mortality risk was no longer significant in any of the groups monitored (smoking duration, number of cigarettes/day). Concrete evidence of the link between all-cause mortality and the length of time since a person stopped smoking also emerged from the large cohort in the American Nurses’ Health Study.
The relative risk for all-cause mortality in women who stopped smoking less than 5 years ago remained high (RR = 1.96, 1.47-2.67), then decreased over time. After 10 years, it was no longer significant (RR = 1.11, 0.92-1.35).
Macro- and microangiopathic risks
Smoking cessation also has a real benefit in terms of the increased macro- and microangiopathic risks. In type 2 diabetes, a study found an increased relative risk for macro- and microalbuminuria of 1.86 (95% confidence interval, 1.37-2.52) in former smokers, compared with an increased relative risk of 2.61 (95% CI, 1.86-2.64) in current smokers.
In type 1 diabetes, the cumulative risk for microalbuminuria in former smokers was 15.1% vs. 18.9% in smokers and 10% in nonsmokers.
A 2019 meta-analysis of prospective cohort studies determined that smoking is an independent risk factor for diabetic nephropathy, especially in patients with type 1 diabetes.
Yet, most of the data for this condition come from subjects with type 2 diabetes. One publication estimated its prevalence after a 1-year follow-up of the smoking cessation program as 10.9% in former smokers and 15% in those who continued smoking.
In regard to macroangiopathy in the context of type 2 diabetes, the aforementioned 2019 meta-analysis focused on coronary artery disease, cerebrovascular accident (CVA), cardiovascular mortality, and myocardial infarction (MI). It found that smokers face an increased risk for all these outcomes.
The relative risks wavered between 1.53 and 1.66 and decreased after smoking cessation. For coronary artery disease and MI, they became insignificant. There was still a risk for CVA (RR = 1.34; 1.07-1.67) and fatal cardiovascular events (RR = 1.19; 0.02-1.39).
The data are slightly more heterogeneous for type 1 diabetes, where, despite smoking cessation, the increased risk for heart failure and CVA persists in men, yet the same risk for coronary heart disease and CVA drops in women.
Risk for weight gain
Dr. Rouland tried to reassure patients about the risk for gaining weight. “Weight gain is not inevitable. There is a risk for this, but it’s temporary. And, even with some weight gain, the cardiovascular benefits are still indisputable.”
A study carried out in 2013 focused specifically on this point, with an average post-cessation weight gain of 3.8 kg (8.4 lb) seen in diabetic individuals in the first 4 years after stopping smoking and of 0.1 kg (0.2 lb) thereafter. A time-based effect was observed with regulation of excess weight post-cessation over time, as seen in the general population (3 kg [6.6 lb] on average in nondiabetic individuals).
Weight gain tends to occur mainly in the immediate post-cessation period, essentially in the first 3 months, and there is a large variation in weight change. Some people gain a lot (from 5 to 10 kg [11 to 22 lb], or even more than 10 kg); others lose weight (20% of diabetic former smokers in the first month, 7% after 12 months), and 25% gain less than 5 kg (11 lb).
Blood glucose imbalance
“A risk for blood glucose imbalance has been reported after smoking cessation, although this is very slight and only temporary,” said Dr. Rouland.
A British retrospective study examined this question, focusing on glycated hemoglobin in patients with type 2 diabetes. Hemoglobin A1c increased by 0.21% (95% CI, 0.17-0.25; P < .001) within the first year after quitting. A1c decreased as abstinence continued and became comparable to that of continual smokers after 3 years. This increase in A1c was not mediated by weight change.
Another study published in 2018 on the topic of type 2 diabetes also reported on the risk for poor glycemic control (defined as A1c > 7%) persisting for 10 years after smoking cessation (odds ratio, 1.23; 95% CI, 1.06-1.42). Thereafter, between 10 and 19 years post-cessation, the OR decreased to 0.97 (95% CI, 0.80-1.19, NS). Beyond 20 years post-cessation, the OR was 1.14 (95% CI, 0.89-1.44, NS) and was therefore no longer significant.
Regardless, “the risk for poor glycemic control is lower in quitters than in active smokers,” said Dr. Rouland.
Quitting and diabetes risk
Will a smoker’s increased risk for diabetes drop when he or she stops smoking? “This is essentially what happens,” Dr. Rouland confirmed, “and his or her increased risk for metabolic syndrome also drops. One meta-analysis revealed a time-based effect.
“Patients who had stopped smoking less than 5 years previously had an increased relative risk for type 2 diabetes, and this risk dropped to 1.11 after more than 10 years of not smoking. Moreover, this relative risk for type 2 diabetes remained lower than that of active smokers, at between 1.19 and 1.60, depending on tobacco use.”
In regard to the risk for metabolic syndrome, those who quit smoking seem to have an increased risk of 10%, compared with nonsmokers (RR = 1.10, 1.08-1.11; P < .001). “But yet again, this increased risk is much lower than that of active smokers, whose risk is between 37% (less than 20 cigarettes/day) and 71% (more than 20 cigarettes/day).”
Women with diabetes
“The benefits of quitting appear identical, regardless of the sex of the diabetic person,” said Dr. Rouland. “As in the general population, weight gain after smoking cessation is greater in women. Furthermore, while smoking increases the risk for gestational diabetes (RR, 1.4-1.9) and for the use of insulin in this context, stopping smoking reduces these risks.
“Moreover, smoking during pregnancy not only increases the risk for pregnancy-related complications (early miscarriage, ectopic pregnancy, birth defects, placental abruption, premature birth, intrauterine fetal demise, cesarean birth, low birth weight), but it also increases the risk of type 2 diabetes in the newborn. The risk to the newborn is said to be around 34% in cases in which the mother smokes during pregnancy and 22% in cases in which the mother is a passive smoker, thereby justifying the use of measures to help the mother’s family members to stop smoking.”
Dr. Rouland reports no relevant financial relationships.

The relative risks wavered between 1.53 and 1.66 and decreased after smoking cessation. For coronary artery disease and MI, they became insignificant. There was still a risk for CVA (RR = 1.34; 1.07-1.67) and fatal cardiovascular events (RR = 1.19; 0.02-1.39).
The data are slightly more heterogeneous for type 1 diabetes, where, despite smoking cessation, the increased risk for heart failure and CVA persists in men, yet the same risk for coronary heart disease and CVA drops in women.
Risk for weight gain
Dr. Rouland tried to reassure patients about the risk for gaining weight. “Weight gain is not inevitable. There is a risk for this, but it’s temporary. And, even with some weight gain, the cardiovascular benefits are still indisputable.”
A study carried out in 2013 focused specifically on this point, with an average post-cessation weight gain of 3.8 kg (8.4 lb) seen in diabetic individuals in the first 4 years after stopping smoking and of 0.1 kg (0.2 lb) thereafter. A time-based effect was observed with regulation of excess weight post-cessation over time, as seen in the general population (3 kg [6.6 lb] on average in nondiabetic individuals).
Weight gain tends to occur mainly in the immediate post-cessation period, essentially in the first 3 months, and there is a large variation in weight change. Some people gain a lot (from 5 to 10 kg [11 to 22 lb], or even more than 10 kg); others lose weight (20% of diabetic former smokers in the first month, 7% after 12 months), and 25% gain less than 5 kg (11 lb).
Blood glucose imbalance
“A risk for blood glucose imbalance has been reported after smoking cessation, although this is very slight and only temporary,” said Dr. Rouland.
A British retrospective study examined this question, focusing on glycated hemoglobin in patients with type 2 diabetes. Hemoglobin A1c increased by 0.21% (95% CI, 0.17-0.25; P < .001) within the first year after quitting. A1c decreased as abstinence continued and became comparable to that of continual smokers after 3 years. This increase in A1c was not mediated by weight change.
Another study published in 2018 on the topic of type 2 diabetes also reported on the risk for poor glycemic control (defined as A1c > 7%) persisting for 10 years after smoking cessation (odds ratio, 1.23; 95% CI, 1.06-1.42). Thereafter, between 10 and 19 years post-cessation, the OR decreased to 0.97 (95% CI, 0.80-1.19, NS). Beyond 20 years post-cessation, the OR was 1.14 (95% CI, 0.89-1.44, NS) and was therefore no longer significant.
Regardless, “the risk for poor glycemic control is lower in quitters than in active smokers,” said Dr. Rouland.
Quitting and diabetes risk
Will a smoker’s increased risk for diabetes drop when he or she stops smoking? “This is essentially what happens,” Dr. Rouland confirmed, “and his or her increased risk for metabolic syndrome also drops. One meta-analysis revealed a time-based effect.
“Patients who had stopped smoking less than 5 years previously had an increased relative risk for type 2 diabetes, and this risk dropped to 1.11 after more than 10 years of not smoking. Moreover, this relative risk for type 2 diabetes remained lower than that of active smokers, at between 1.19 and 1.60, depending on tobacco use.”
In regard to the risk for metabolic syndrome, those who quit smoking seem to have an increased risk of 10%, compared with nonsmokers (RR = 1.10, 1.08-1.11; P < .001). “But yet again, this increased risk is much lower than that of active smokers, whose risk is between 37% (less than 20 cigarettes/day) and 71% (more than 20 cigarettes/day).”
Women with diabetes
“The benefits of quitting appear identical, regardless of the sex of the diabetic person,” said Dr. Rouland. “As in the general population, weight gain after smoking cessation is greater in women. Furthermore, while smoking increases the risk for gestational diabetes (RR, 1.4-1.9) and for the use of insulin in this context, stopping smoking reduces these risks.
“Moreover, smoking during pregnancy not only increases the risk for pregnancy-related complications (early miscarriage, ectopic pregnancy, birth defects, placental abruption, premature birth, intrauterine fetal demise, cesarean birth, low birth weight), but it also increases the risk of type 2 diabetes in the newborn. The risk to the newborn is said to be around 34% in cases in which the mother smokes during pregnancy and 22% in cases in which the mother is a passive smoker, thereby justifying the use of measures to help the mother’s family members to stop smoking.”
Dr. Rouland reports no relevant financial relationships.

MONTPELLIER, FRANCE – The first expert consensus on smoking and diabetes, coauthored by the Francophone Diabetes Society (SFD) and the French Society for the Study of Nicotine Addiction (SFT), was presented at the SFD’s annual conference.
Alexia Rouland, MD, an endocrinologist at Dijon Bourgogne University Hospital, Dijon, France, took the conference as an opportunity to list the many benefits of smoking cessation for patients with diabetes, despite the “slight and temporary” risk for blood sugar imbalance.
Societies target smoking
Diabetes societies around Europe have set their sights on the topic of smoking. Indeed, the guidelines published in 2019 by the European Association for the Study of Diabetes and the European Society of Cardiology state that “smoking cessation is obligatory for all prediabetic and diabetic patients” (class I, level A).
This year, the France-based SFD and SFT dedicated an expert consensus to the major problem of smoking in patients with diabetes. The aim was to provide health care professionals with convincing, well-supported arguments in favor of smoking cessation in their patients with type 1 and type 2 diabetes.
“Before anything else, diabetic patients need to be made aware of the risks of smoking,” said Dr. Rouland. “It’s not just about the fear factor, though. It’s also about providing a positive incentive – they need to be told about the ways they’ll benefit from quitting smoking. For example, you have all-cause mortality, macro- and microangiopathic complications, and so on.”
Duration of abstinence
“Diabetic patients who have stopped smoking have a relative risk for all-cause mortality of 1.28 (1.09-1.51), which is less than what you see in active smokers (relative risk = 1.58; 1.42-1.77), but still above that of nonsmokers,” said Dr. Rouland.
A previous study revealed that although the risk does indeed go down after stopping smoking, it is linked to how long ago the person stopped. Patients who stopped smoking less than 10 years ago still had a slightly raised all-cause mortality risk, and this was even higher if they had smoked for 20 years or more.
After 10 years of not smoking, however, the greater all-cause mortality risk was no longer significant in any of the groups monitored (smoking duration, number of cigarettes/day). Concrete evidence of the link between all-cause mortality and the length of time since a person stopped smoking also emerged from the large cohort in the American Nurses’ Health Study.
The relative risk for all-cause mortality in women who stopped smoking less than 5 years ago remained high (RR = 1.96, 1.47-2.67), then decreased over time. After 10 years, it was no longer significant (RR = 1.11, 0.92-1.35).
Macro- and microangiopathic risks
Smoking cessation also has a real benefit in terms of the increased macro- and microangiopathic risks. In type 2 diabetes, a study found an increased relative risk for macro- and microalbuminuria of 1.86 (95% confidence interval, 1.37-2.52) in former smokers, compared with an increased relative risk of 2.61 (95% CI, 1.86-2.64) in current smokers.
In type 1 diabetes, the cumulative risk for microalbuminuria in former smokers was 15.1% vs. 18.9% in smokers and 10% in nonsmokers.
A 2019 meta-analysis of prospective cohort studies determined that smoking is an independent risk factor for diabetic nephropathy, especially in patients with type 1 diabetes.
Yet, most of the data for this condition come from subjects with type 2 diabetes. One publication estimated its prevalence after a 1-year follow-up of the smoking cessation program as 10.9% in former smokers and 15% in those who continued smoking.
In regard to macroangiopathy in the context of type 2 diabetes, the aforementioned 2019 meta-analysis focused on coronary artery disease, cerebrovascular accident (CVA), cardiovascular mortality, and myocardial infarction (MI). It found that smokers face an increased risk for all these outcomes.
The relative risks wavered between 1.53 and 1.66 and decreased after smoking cessation. For coronary artery disease and MI, they became insignificant. There was still a risk for CVA (RR = 1.34; 1.07-1.67) and fatal cardiovascular events (RR = 1.19; 0.02-1.39).
The data are slightly more heterogeneous for type 1 diabetes, where, despite smoking cessation, the increased risk for heart failure and CVA persists in men, yet the same risk for coronary heart disease and CVA drops in women.

What new cardiovascular disease risk factors have emerged?
Cardiovascular disease (CVD) is the main cause of premature death and disability in the general population, and according to the World Health Organization, the incidence of CVD is increasing throughout the world. Conventional risk factors that contribute to the occurrence and worsening of CVD have been identified and widely studied. They include high cholesterol levels, high blood pressure, diabetes, obesity, smoking, and lack of physical activity. Despite the introduction of measures to prevent and treat these risk factors with lipid-lowering drugs, antihypertensives, antiplatelet drugs, and anticoagulants, the mortality rate related to CVD remains high.
Despite the effectiveness of many currently available treatment options, there are still significant gaps in risk assessment and treatment of CVD.
They are detailed in an editorial published in The American Journal of Medicine that describes their role and their impact on our cardiovascular health.
Systemic inflammation
The new coronary risk factors include the following diseases characterized by systemic inflammation:
- Gout – Among patients who have experienced a recent flare of gout, the probability of experiencing an acute cardiovascular event such as a myocardial infarction or stroke is increased.
- Rheumatoid arthritis and systemic lupus erythematous – Patients with one or both of these conditions are at higher odds of experiencing concomitant premature and extremely premature coronary artery disease.
- Inflammatory bowel disease (Crohn’s disease or ulcerative colitis) – Patients with this disease have increased odds of developing coronary artery disease.
- Psoriasis – Patients with psoriasis are up to 50% more likely to develop CVD.
Maternal and childhood factors
The following maternal and childhood factors are associated with an increased risk of developing coronary artery disease: gestational diabetes; preeclampsia; delivering a child of low birth weight; preterm delivery; and premature or surgical menopause. The factor or factors that increase the risk of coronary artery disease associated with each of these conditions are not known but may be the result of increased cytokine and oxidative stress.
An unusual and yet unexplained association has been observed between migraine headaches with aura in women and incident CVD.
Also of interest is the association of early life trauma and the risk of adverse cardiovascular outcomes in young and middle-aged individuals who have a history of myocardial infarction.
Transgender patients who present for gender-affirming care are also at increased cardiovascular risk. Among these patients, the increase in coronary artery disease risk may be related to high rates of anxiety and depression.
Environmental factors
Low socioeconomic status has emerged as a risk factor. Increased psychosocial stressors, limited educational and economic opportunities, and lack of peer influence favoring healthier lifestyle choices may be causative elements leading to enhanced coronary artery disease among individuals with low socioeconomic living conditions.
Air pollution was estimated to have caused 9 million deaths worldwide in 2019, with 62% due to CVD and 31.7% to coronary artery disease. Severely polluted environmental aerosols contain several toxic metals, such as lead, mercury, arsenic, and cadmium. Transient exposure to various air pollutants may trigger the onset of an acute coronary syndrome.
Lifestyle factors
Long working hours by patients who have experienced a first myocardial infarction increase the risk for a recurrent event, possibly because of prolonged exposure to work stressors.
Skipping breakfast has been linked to increased cardiovascular and all-cause mortality.
Long-term consumption of drinks containing sugar and artificial sweeteners has also been associated with increased cardiovascular mortality.
Recognizing the presence of one or more of these new risk factors could help prompt and improve behaviors for reducing more conventional CV risk factors to a minimum.

New ACC guidance on heart failure with preserved ejection fraction
The American College of Cardiology has released an Expert Consensus Decision Pathway (ECDP) on the management of heart failure with preserved ejection fraction (HFpEF).
The 44-page document highlights the “critical need” to accurately diagnose HFpEF to permit timely implementation of evidence- and guideline-based therapies to improve patient outcomes.
Although the incidence of overall HF in the United States appears to be stable or declining, the incidence of HFpEF continues to rise in tandem with increasing age and burdens of obesity, sedentary lifestyle, and cardiometabolic disorders.
HFpEF now accounts for more than one half of HF cases but remains “underrecognized” in everyday clinical practice, said the writing group, led by Michelle Kittleson, MD, PhD, professor of medicine, Smidt Heart Institute, Cedars-Sinai Medical Center, Los Angeles.
HFpEF is a complex condition, often with multiple overlapping comorbidities, including hypertension, diabetes, obesity, and sleep apnea; optimal management requires a multidisciplinary approach, the writing group said.
The ECDP on HFpEF lays out a structure for diagnosis, clinical decision-making, management of comorbidities, implementation of the latest guideline-directed medical therapy (pharmacologic and nonpharmacologic), and equitable delivery of care.
The document was published online in the Journal of the American College of Cardiology.
It aligns with and builds on recommendations from the 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure.
“HFpEF is one of the most pressing diagnostic and therapeutic challenges in clinical medicine today given its increasing prevalence, under diagnosis, poor prognosis, limited therapeutic options, and substantial burden on the health care system worldwide,” wrote the authors of a companion scientific statement on HFpEF.
Despite these challenges, the success of recent sodium-glucose cotransporter 2 inhibitor trials has shown that HFpEF is treatable, Barry Borlaug, MD, department of cardiovascular medicine, Mayo Clinic, Rochester, Minn., and coauthors pointed out.
They noted that “ongoing large-scale studies of HFpEF pathobiology, an increasing number of translational studies spanning the gap between the bedside and the bench, and numerous clinical trials of novel therapeutics in HFpEF offer a glimpse of hope toward a future of reduced prevalence, morbidity, and mortality associated with HFpEF, which would be a major advance for population health.”

Meditation curbs stress, depression as adjunct to CAD rehab
Regular meditation reduced depression by roughly 44% in adults with coronary artery disease who were involved in a cardiovascular rehabilitation program.
An increasing body of research supports the impact of psychological risk factors including stress, personality type, anger, and hostility on conditions such as depression and anxiety, but also social isolation and low socioeconomic status, Ana Luisa Vitorino Monteiro, MD, of the University of Lisbon said in a presentation at the annual congress of the European Association of Preventive Cardiology. In addition, “stress, anxiety, and depression deteriorate the cardiovascular (CV) system through psycho-neuro-immunoendocrinology system and behavioral pathways.”
Meditation as a tool for stress management has been gaining popularity, but its use as part of a CV rehabilitation program as a complementary therapy has not been well studied, she added.
Dr. Monteiro and colleagues recruited 80 adults with CAD who were undergoing CV rehabilitation to join a meditation program. Of these, 48 accepted (60%) and 40% declined. Those who accepted were part of an exercise-based CV rehabilitation program that met three times a week for at least 6 months. The mean age of the participants was 65 years, and 80% were male.
Participants were randomized to an intervention group with a weekly 90-minute session that included breathing and meditation for 1 month in addition to usual care, or to usual care in the rehabilitation program. Over the next 3 months, the intervention patients were encouraged to practice daily meditation for 20 minutes alone or using video support material, with a weekly follow-up phone call. Assessments of stress, anxiety, and depression took place at baseline and after 4 months using the Perceived Stress Scale, Beck Anxiety Inventory, Beck Depression Inventory, and HeartQoL questionnaire.
At 4 months, individuals in the meditation group had reduced depression levels significantly, by 44%, compared with controls (P < .001). Anxiety and stress decreased significantly, by 30% (P = .04) and 31% (P = .05), respectively. After 4 months, individuals in the control group were offered the opportunity to follow the meditation protocol.
In addition, “the emotional dimension of quality of life increased by 60% in the intervention group,” Dr. Monteiro noted. However, physical QoL did not change between groups.
The study was limited by the small sample size, and more research is needed in larger and more diverse populations, Dr. Monteiro said. However, the results support the value of meditation as an adjunct component of care for CAD patients in a long-term rehabilitation program.
Motivation makes a difference
The current study is important as an exploration of “a straightforward, simple, low-risk approach that could be an adjunct to benefit patients with serious cardiovascular disease,” Brian Olshansky, MD, a cardiologist at the University of Iowa, Iowa City, said in an interview.
“We have moved into a time of polypharmacy and multiple interventions for patients with underlying cardiovascular disease which, in many cases, have proven benefit but also potential adverse effects,” he said. “Engaging patients to participate in their health care, when there is serious underlying cardiovascular disease, has potential beneficial impact in many ways. Meditation is a low-risk, low-cost, potentially beneficial adjunct to standard medical therapy that may enhance psychological outcomes as shown here in this small study.”
However, “patients often rely on high-cost, potentially high-risk therapeutic interventions, expecting complete control of their problems without their own collaborative intervention,” he noted.
Dr. Olshansky said he was not surprised by any of the findings, and would have been surprised if meditation had failed to show any benefit for the study population.
“I am very pleased to see these results and would encourage meditation practice to be part of cardiovascular rehabilitation for motivated individuals,” he said. “What did surprise me was the adherence to the meditation protocol for those who participated. This represents a highly motivated group and it may be difficult to expect the same results in less motivated individuals.”
The current study has several strengths, including the use of controls and high rates of adherence to the protocol, said Dr. Olshansky. Other strengths include the standardized approach and the reasonable quality of the outcome measures, which showed a substantial benefit.
However, “this is a small study of motivated individuals of whom 80% were male,” and generalizability to other populations is unclear, Dr. Olshansky said. In addition, the racial mix was not described, and the severity of the underlying coronary artery disease and the therapies provided to these individuals is not detailed. A sicker population may not fare as well.”
The reasons for the benefits of meditation remain uncertain, Dr. Olshansky said. “It could be, specifically, that the meditation itself has physiological effects that ultimately translate into psychosocial benefit. However, those who enrolled and were interested may have derived a placebo effect. In any case, benefit was achieved, but the crossover benefit to the control group is unclear.
“In other words, the statistical approach to benefit is uncertain as to when it was measured, but presumably before the control group was allowed to engage in a meditation practice,” and the follow-up was short term, said Dr. Olshansky.
Data support patient engagement
The message to clinicians and patients: “Patients should be engaged in their own health care when it comes to rehabilitation for cardiovascular disease,” said Dr. Olshansky. “Motivated individuals who are educated about a meditative practice performed in a standardized way will have improvement most likely in their quality of life, and when it comes to measurements of depression, stress and anxiety.”
Although the mechanisms behind the benefits remain unclear, “having a standardized credible prescription for which patients can become intimately engaged is beneficial,” he added.
The study received no outside funding. Neither Dr. Monteiro nor Dr. Olshansky had any financial conflicts to disclose.
Regular meditation reduced depression by roughly 44% in adults with coronary artery disease who were involved in a cardiovascular rehabilitation program.
An increasing body of research supports the impact of psychological risk factors including stress, personality type, anger, and hostility on conditions such as depression and anxiety, but also social isolation and low socioeconomic status, Ana Luisa Vitorino Monteiro, MD, of the University of Lisbon said in a presentation at the annual congress of the European Association of Preventive Cardiology. In addition, “stress, anxiety, and depression deteriorate the cardiovascular (CV) system through psycho-neuro-immunoendocrinology system and behavioral pathways.”
Meditation as a tool for stress management has been gaining popularity, but its use as part of a CV rehabilitation program as a complementary therapy has not been well studied, she added.
Dr. Monteiro and colleagues recruited 80 adults with CAD who were undergoing CV rehabilitation to join a meditation program. Of these, 48 accepted (60%) and 40% declined. Those who accepted were part of an exercise-based CV rehabilitation program that met three times a week for at least 6 months. The mean age of the participants was 65 years, and 80% were male.
Participants were randomized to an intervention group with a weekly 90-minute session that included breathing and meditation for 1 month in addition to usual care, or to usual care in the rehabilitation program. Over the next 3 months, the intervention patients were encouraged to practice daily meditation for 20 minutes alone or using video support material, with a weekly follow-up phone call. Assessments of stress, anxiety, and depression took place at baseline and after 4 months using the Perceived Stress Scale, Beck Anxiety Inventory, Beck Depression Inventory, and HeartQoL questionnaire.
At 4 months, individuals in the meditation group had reduced depression levels significantly, by 44%, compared with controls (P < .001). Anxiety and stress decreased significantly, by 30% (P = .04) and 31% (P = .05), respectively. After 4 months, individuals in the control group were offered the opportunity to follow the meditation protocol.
In addition, “the emotional dimension of quality of life increased by 60% in the intervention group,” Dr. Monteiro noted. However, physical QoL did not change between groups.
The study was limited by the small sample size, and more research is needed in larger and more diverse populations, Dr. Monteiro said. However, the results support the value of meditation as an adjunct component of care for CAD patients in a long-term rehabilitation program.
