At the Kahn Center for Cardiac Longevity we teach patients about the large amount of scientific data to support whole food plant-based diets. They are the only diets to reverse heart disease and early dementia. On an initial visit to the clinic, the most common response to questioning about meal...

At the Kahn Center, we teach the science of whole food, plant diets, generally lower in fats, for heart disease prevention and reversal. This is based on studies by legends like Lester Morrison, MD, Nathan Pritikin, Dean Ornish, MD, Caldwell Esselstyn, MD, Joel Fuhrman, MD and others.  A variation on...

Ever since longevity expert Dan Buettner of the Blue Zones advised eating 120 beans every day, ways to increase the quantity of legumes eaten every day has been a goal of mine. Let me introduce you to one of my secret snacks, the lupini bean. What is a lupini bean?...

At the KAHN CENTER, we have developed a specialty in diagnosing and managing the genetic cholesterol particle called Lipoprotein(a) or Lp(a). This is found in up to 25% of all person by a simple blood test but most doctors do not check for it.   Elevated Lp(a) concentrations are associated...

For over a decade, the approach at the KAHN CENTER for lowering LDL cholesterol (LDL-C) in those who need therapy has been to combine a low dose of a statin with ezetimibe. The results have been excellent and even Lipoprotein(a) has been seen to go down in many patients. This...

A lot of the patients at the Kahn Center use cannabis products recreationally for relaxation and sleep. This comes up in conversation but is not always a routine question like questions about cigarette smoking, alcohol and exercise patterns. Is it time to add questions about cannabis use to the history...

 We have recently begun asking patients at the Kahn Center about their hearing. Why? Read on as the link between hearing loss and the risk of dementia needs to be better appreciated. And there is a diet to help! And it involves lots of plants!  Hearing loss poses a significant...

At the Kahn Center we teach plant-based diets with no or low oil content, preferably extra-virgin olive oil. There has been an uptick in interest in butter and beef tallow from the #MAHA and ancestral health groups. Is there new data to consider? A new study provides convincing reasons to...

Longevity and healthspan is a complex equation but the foods we chooose to eat (and the way we prepare them) have much to do with a healthy life. Many studies have strived to identify foods associated with longer lifespans. It is essential to integrate the most reliable evidence regarding intake...

The standard lab panel, if one is done at all, in a cardiology office, even a university clinic visit, harks back to the 1980s, as nothing has changed. One of the lab tests that should be routinely done, at least in the experience of the Kahn Center for Cardiac Longevity,...

Niacin, or vitamin B3, is found in foods and can also be used as an inexpensive suppelment.  Studies in the 1970s (Coronary Drug Project) showed that supplemental niacin used in heart patients improved outcomes, presumably due to the favorable impact on cholesterol.  In the last decade, supplemental niacin has become...

Dementia affects 55 million people globally, with the number projected to triple by 2050. Statins, widely prescribed for cardiovascular benefits, may also have neuroprotective effects, although studies on their impact on dementia risk have shown contradictory results. Is it safe to take statins in terms of brain health? So many...

Any activity like walking is better than prolonged sitting and should be encouraged. "Forest bathing" is a term used more in Japan for exercising in greenspaces and forests. It has been suggested that forest bathing is a healthier form of exercise. Now it has been put to the test in...

In my over 35 years of heart patient care, including 25 years using innovations in the cardiac catheterizaiton laboratory, it is my opinion that Coronary CT Angiography (CCTA) with AI interpretation (Cleerly Health) is the most important breakthrough for accurate diagnosis and disease tracking. I have ordered hundreds if not...

The #MAHA movement (Make America Healthy Again) is gaining momentum to provide safer and more nutritious foods to stores and schools. This extends to the pharmaceutical industry too. This week, a small victory was announced: Red No.3 is being banned. The FDA is revoking the authorization for the use of...

Although guidelines recommend low-density lipoprotein cholesterol (LDL-C) to be at least < 70 mg/dL (and more optimally <55 mg/dL) in patients with atherosclerotic cardiovascular disease (ASCVD), the rate of achieving this goal remains suboptimal. A new study sought to understand real world contemporary practice patterns of LDL-C management in patients...

One might think that there is a debate in science how a plant-based diet compares with a meat based diet. In reality, the vast majority of actual science studies favor a plant-based diet. This has been the case for 70 years.  How much does the decision between choosing a plant-based...

Heart disease, like hypertension or a heart attack, usually manifests in adulthood, with the peak age for heart attacks in men being age 65. It is known that the disease has been going on for a very long time by the time that happens. But how long. A new study...

Despite all the planning and joy that the holidays can bring by reuniting families and traditions, it is shocking that Christmas holidays have been associated with more heart attacks (MI) than any other day of the year!  Why? A study from Sweden examined possible triggers of MI during Christmas and...

The adverse health effects of sugar-sweetened beverage intake are well-established, but the implications of overall added sugar intake remain unclear. In studies done over 50 years ago (The Seven Countries Study for one), dietary sugar was linked to coronary artery disease (CAD) risk, particularly when found in pasttries. Dietary sugar...

The risk of cardiovascular disease (CVD) is increased in individuals with type 2 diabetes mellitus (T2DM), but it remains uncertain how long an elevated CVD risk precedes diabetes diagnosis.  It may be that elevated blood sugars and pre-diabetes start the march towards "clinical" CVD likes strokes, heart attacks, stents, bypass...

For the first time in my memory, public policy out of Washington, DC is focusing on the root causes of poor health, health expenses and longevity. It appears that Robert F. Kennedy, Jr will lead this important effort under the head ing of MAHA or Make America Healthy Again (#MAHA)....

A whole food plant diet has over 70 years of data to support its ability to prevent and reverse disease and aging. Why isn't everyone eating this way? One concern is that this diet is too expensive. A new study analyzed a standard diet costs versus a low-fat vegan diet...

Many patients schedule a visit to the Kahn Center (office or virtual) because they have learned they inherited a cholesterol molecule called Lipoprotein(a) or Lp(a). This particle, Lp(a), is found in 20-25% of people and can promote damage to blood vessels and the aortic valve leading to heart attacks, strokes,...

The basics of cardiovascular health (CVH) remain a whole food, plant-based diet, fitness, avoidance of smoking, and adequate sleep. Beyond these pillars, sauna bathing has a suprising large amount of research to support its role for CVH. I have had a full spectrum infrared sauna (Sunlighten Saunas) in my home...

At the Kahn Center for Cardiac Longevity, we have a toolbox that is broad and includes food based approaches. For over 7 years, one of those tools has been the PROLON 5-day Fasting Mimicking Diet (www.prolonlife.com/drkahn). There are many research and clinical trials demonstrating the benefits of this science backed...

Longevity is increasing worldwide due to improvements in healthcare and living standards. Aging is often associated with disability and multiple health concerns. To address these challenges, effective interventions are essential. Good balance, muscle strength and an efficient gait contribute to people's independence and well-being as they age. How these factors...

As many women suffer and die of cardiovascular diseases (CVD) as men but may get less attention in general (not at the Kahn Center for Cardiac Longevity. The American Heart Association (AHA) is celebrating its 100th anniversary of education the public and is emphasizing women's heart health amongst other topics....

In my preventive clinic, the focus is long-term cardiac but cancer, diabetes, and dementia risk is reviewed. A largely ignored pathway of disease known as advanced glycation end-product (AGEs) accumulation is a focus as the Kahn Center as it leads to all major chronic diseases. We now measure AGEs at...

In the 1600's, the leading physician in England (Thomas Sydenham, MD) wrote that "A man is as old as his arteries".  We would now change that to "A person is as old as his or her arteries" but Dr. Sydenham's viewpoint has proven to be accurate and visionary. At the...

The official recommendation of achieving at least 150 minutes of moderate-to-vigorous physical activity per week is associated with lower risk of adverse cardiovascular events and represents an important public health priority. Many people have schedules that make it difficult to get to the gym or work out at home during...

The Rolling Stones sang the phrase "I can't get no, satisfaction" and many of us still rock to their music. However, with cardiovascular diseases (CVD) remaining a leading global health concern, does "satisfaction" have anything to do with heart disease and outcomes? The role of well‐being in reducing CVD risk...

The notion that plant-based diets are optimal for health and prevent cardiovascular disease (CVD) goes back at least to the 1950's. Yet, "food wars" still exist with some denying the power of plant diets. More data is needed and an emphasis on raw vegetable consumption is of interest. A new...

At the Kahn Center for Cardiac Longevity, all patients either bring extensive lab testing or they arrange, in the clinic or at a distance, a large panel of lab tests that are predictive of heart disease, its causes, and its implications for the future.  For years, this panel has included...

The language of food science, particularly plant science, can be intimidating. One word that recurs over and over is polyphenols.  What are they and why are they important? Where are they found in the diet? Polyphenols are a type of chemical naturally occurring in plant-based foods like fruits, vegetables, whole...

The "low-carb" movement (ketogenic, Paleo, carnivore diets) have given potatoes a bad name. Even the Harvard School of Public Health does not list them as a healthy food, undoubtedly because so many potatoes are eaten as french fries, not simply boiled or baked. Other advocates, particularly, the recently deceased John...

The optimal amount of dietary fat and the kind of dietary fat intake on long-term human has attracted major attention, debate, and disagreement between health experts, to say the least!  More data is welcome on whether fats are healthy and what kind of fats are healthiest. A new large study...

One of the most frustrating events at the Kahn Center is to evaluate a patient with a heart attack or stroke history and not find a "major" risk factor like Lipoprotein(a) or a high homocysteine. Of course, all traditional risk factors like smoking are evaluated too. Stanley Hazen, MD of...

The Paleo diet is designed to resemble what human hunter-gatherer ancestors ate thousands of years ago. It is also called an ancestral diet and a Caveman diet. It tends to be a meat heavy diet, and some promote "beef, butter, bacon, and eggs" as the key components of a proper...

At the Kahn Center for Cardiac Longevity, we spend considerable time discussing memory and longevity with all patients, including the female patients, and often recommend hormone replacement therapy or HRT. Many do not know that females represent approximately 70% of the Alzheimer's disease (AD) cases and the literature has proposed...

At the Kahn Center, we see many patients for evaluation of their coronary heart disease (CHD) and aortic valve stenosis (AVS) from a calcified valve. For over a decade, a routine lab test has been to measure Lipoprotein( a) or Lp(a) in all patients. Lp(a) is an important inherited factor...

A common question at the Kahn Center centers on the role of collagen supplements for skin and hair health, artery health, and bone health. Most collagen supplements are made from animals like cows and we do not recommend those. There has been limited science of vegan options There is a...

Although our focus at the Kahn Center is the prevention of heart disease, the integrative approach we takes strives for total body health. Bone health shares many features with heart health (exercise, healthy diet, optimal weight, limited alcohol, supplements, and good sleep to name a few). The loss of bone...

In 2019, the EAT-Lancet Commission gained headlines worldwide when it proposed a healthy dietary pattern that, along with reductions in food waste and improved agricultural practices, could feed the increasing global population sustainably. Now a Planetary Health Diet Index (PHDI) has been developed to quantify adherence to the EAT-Lancet reference...

Back in 2018, I appeared on the Joe Rogan Podcast (Episode 1175) and spent nearly 4 hours debating nutrition with Chris Kresser. He brought up some data that fish have TMAO in them, fish are considered heart healthy (debatable), and therefore plant diets are not the best choice. There was...

While a whole food plant diet is the recommendation at the Kahn Center, the science of certain nutrients like creatine and choline is discussed with patient and strategies to eat or supplement some nutrients may important for optimal health. Choline, an indispensable nutrient, plays a pivotal role in various physiological...

Althought heart disease impacts many more people than Alzheimer's Dementia (AD), people fear AD the most due to the loss of control and the deterioration in quality of life. Advances in reversing early AD have been slow and the medications are controversial at best. At the Kahn Center we discuss...

At the Kahn Center, we stress education on nutrition on every visit and provide a list of documentaries, books and podcasts to study at home. While the emphasis is a whole food plant diet (healthy vegan), information on the Mediterranean (MED) diet is also provided due to a large body...

At the Kahn Center it is routine to measure and Omega Index and a large percentage of patients are very low in Omega-3. This is true of those following a vegan diet and those on omnivore diets. Many patients are seen already taking some kind of Omega-3 supplements, usually fish...

There is much interest in strategies to address aging and prolong lifespan and healthspan. An industry has grown up of tests offered to measure "biological age". These usually involve samples of blood or cheek swabs. A prior study indicated that the widely available coronary artery calcium score (CACS) done by...

Although heart disease takes many more lives than dementia, people search for advice on avoiding dementia and express fear over developing dementia more frequently than efforts to prevent heart disease. Clues to delaying and preventing dementia are needed and diet may play a role. Can extra-virgin olive oil in the...

Everyone has heard of someone angry, yelling and then drops over dead. Why? Provoked anger is associated with an increased risk of cardiovascular disease events. The underlying mechanism linking provoked anger as well as other core negative emotions including anxiety and sadness to cardiovascular disease remain unknown. The study objective...

In discussions with my patients at the Kahn Center for Cardiac Longevity, a routine question is asking about memory and cognitive function. It is surprising how often the response is one of concern over failing memory. Simple approaches to enhancing cognitive function are needed.  Roasted green tea, also known as...

Atrial fibrillation (AF) is a specific kind of irregular heart beat that can be silent or symptomatic and impacts millions of people. We see many patients with AF at the Kahn Center for Cardiac Longevity, some of whom are in AF chronically and some go in and out of it...

Chelation therapy is an intravenous (and occasionally oral or rectal) therapy to remove toxic levels of heavy metals like mercury, lead, arsenic, and cadmium from the body and is approved for that purpose. Over many decades there has been the thought that it could serve as a therapy for heart...

The lipoprotein(a) [Lp(a)] field is rapidly evolving on many fronts, including understanding of the association between Lp(a) levels and cardiovascular disease (CVD) risk in different contexts, and how best to manage other CVD risk factors in patients with elevated Lp(a). Considering new insights into the clinical management of these patients,...

One of the most interesting stories in pharmaceuticals is the development of Viagra (sildenafil) as a heart medication that had an unexpected but happy side effect: effective treatment of erectily dysfunction (ED). Viagra and Cialis went on to become blockbuster drugs that are both generic now.  Over the years, these...

The risk of aging and developing memory loss and dementia is often a greater fear expressed by patients in my clinic than heart disease or cancer outcomes. Strategies to prevent memory loss are evolving but it is clear that regular exercise and healthy diets, along with adequate sleep and weight...

There has been hopeful data for over 30 years that atherosclerosis in coronary and carotid arteries may be reversed to an extent by lifestyle measures focused on a plant diet.  A "new kid on the block" has been a nutraceutical based on green seaweed combination. Recently, a small study has...

At the Kahn Center, we emphasize lifestyle and corrective measures to promote health and prevent or reverse illness. One factor often ignored is the quality and quantity of sleep. Sleep apnea has become a major factor for cardiovascular and overall health and is easily tested at the Kahn Center by...

One of the most common concerns patients share with me at the Kahn Center is their fear that lowering their cholesterol levels with "statin" medications like atorvastatin or rosuvastatin might promote dementia.  Indeed, the potential impact of statins on cognitive decline and dementia is still debated but their is considerable...

The news cycle this week is full of headlines connecting high levels of niacin to coronary heart disease through pathways of accelerated inflammation based on a new study from the Cleveland Clinic Foundation. Although many clinicians have abandoned the use of niacin in practice, there are many theoretical and trial...

It is no secret that various fasting programs show up in the news over and over. When I discuss diet with my patients, a large number of them skip breakfast and try and eat in a 6-8 hour window. Technically, this is not fasting but a form of "time restricted...

It is estimated that we are exposed to over 80,000 industrial chemicals with only a small fraction having been studied for health consequences. One family of chemicals that has been studied is the bisphenol family such as BPA and BPS, used since the 1950s. BPA and BPS  have been reported...

Prehypertension, defined as systolic blood pressure (SBP) of 120 to 139 mm Hg and/or diastolic BP (DBP) of 80 to 89 mm Hg, increases the risk of developing hypertension and other cardiovascular diseases. Early and effective intervention for patients with prehypertension is highly important. STUDY OBJECTIVE  To assess the efficacy of Tai...

The researchers who identified Nitric Oxide (NO) as a small molecule made by the endotherlial lining of arteries to promote blood flow and resist atherosclerosis won the Nobel Prize in Medicine in 1998. Despite that, NO rarely comes up in clinical care as it is hard to measure and no...

A large portion of the patients seen at the Kahn Center are interested in learning if they inherited the genetic capacity to produce Lipoprotein(a) or Lp(a) or "the sticky cholesterol". Others know they inherited it at a high level and seek guidance. As you know, I wrote a book on...

It is so frustrating that coronary artery calcium scoring (CACS) has been available for decades, is safe, painless, and inexpensive, and reveals the degree of silent coronary artery disease (CAD) but so few people have one of these scans. Primary care doctors are still not ordering them even though most...

Does anything that takes good actually promote health? I would answer yes as I love lentils, chickpeas, kidney beans, arugula and many other plant based goodies. But off the list is pepperoni pizza, hot dogs, croissants, and butter. The good news is that a new analysis in a prominent journal...

There are hundreds of research studies identifying the benefits of a whole food plant-based (WFPB) diet. The holy grail would be if a WFPB diet actually slowed or reversed aging. New science has been published that suggests this may be the case and in only 8 weeks. The research study...

I take a sleep history from all patients cared for at the Kahn Center and it is impressive how many patients have a habit of staying up to midnight, 1AM, or even later night after night, the classic night owl. Not for me, lights out by 10PM or earlier. Does...

I am reposting a recent interview from this site to share the questions and answers for this audience.  What do you get when you combine veganism, cardiology and prevention? You get a holistic cardiologist passionate about the health benefits of a plant-based, anti-ageing diet. Join us in learning more about...

Cardiovascular diseases (CVD) are the leading cause of death in the world with around 20 million deaths annually.  Diet plays a major role in the development and progression of these diseases. The timing of meals may also play an important role. So many people are skipping breakfast and not eating...

The easiest way to assess sleep is to measure how many hours of sleep were achieved but that may not be the only measure that matters. Menopause can be particularly disruptive for sleep for many women. In the American Heart Association's Life’s Essential 8 (LE8) the only measure of sleep...

Are you considering a health upgrade for 2024? Adopting a plant-based diet of whole foods may be your best choice. Need some convincing? Wondering what are benefits of a healthy plant-based (vegan) vs a healthy omnivorous diet among even for just 8-weeks?  A new study provides the answer and suggests...

I served as medical director of several large cardiac rehabilitation (CR) programs in Michigan and have a special place in my heart and practice for getting all qualifying patients into a CR program. When I can, I try to refer to an intensive CR program or ICR using the principles...

If you have heard it once, you have heart it a million times: whole plant food diets are the healthiest choice on the planet and for the planet. As Michael Greger, MD says, if all that whole food plant diets did was halt and reverse the #1 cause of death...

The approach to patients with established coronary artery disease (CAD)has been make progress including lifestyle, supplemental, and Rx approaches but more "tools" in the tool box are still needed. The explosion in overweight and obese heart patients is a major challenge. Semaglutide (knows as Wegovy for weight loss), a glucagon-like...

BACKGROUND You’ve heard of the Atkins, MED, vegn, Paleo. Keto, and DASH diets over the years but have you heard of the Portfolio Diet? A prior Kahn Center blog did discuss this diet pattern. Now, America’s most influential journal for heart health is exploring the benefits of the portfolio diet. ...

The potential implications of delaying or preventing memory issues and cognitive decline for the roughly 6.5 million Americans over 65 diagnosed with Alzheimer’s as of 2022, a figure expected to more than double by 2060, are huge. Diet plays a role. A popular diet is the Dietary Approaches to Stop...

For many patients with a high LDL-cholesterol and confirmed atherosclerosis (prior heart attack, stent, bypass surgery, carotid surgery, abdominal aneurysm high calcium score, abnormal coronary CT angiogram), lifestyle changes along with medications to lower the LDL-C are indicated. Statin medications are the most common prescription to lower LDL-C but they...

You would think we would know by now what is the optimal diet for health and longevity but the "food wars" are endless. One reason is that nutrition science is very complicated and randomized studies (like the Predimed and Cordioprev trials) are difficult and rare. Much of the science is...

TYPE 2 DIABETES MELLITUS IS A KILLER The prevalence of type 2 diabetes (DM2) is increasing rapidly, particularly among younger age groups. Estimates suggest that people with diabetes die, on average, 6 years earlier than people without diabetes.   A new large study aimed to provide reliable estimates of the...

Without a doubt, fitness, endurance, and exercise is a fundamental step in long-term health. A concept was introduced a few years ago called NEAT or non-exercise activity thermogenesis, or movement and fitness in daily life, not the gym, that matters for health. Climbing stairs, rather than the elevator, is one...

Globally, more than 1.9 billion adults are overweight (650 million with obesity). In Australia, where new research on weight loss diets was just completed, two in three people (approximately 12.5 million adults) are overweight or have obesity. Can nuts be part of a weight loss diet?  When it comes to...

A recent study found that about 50% of a random sample of adults in the USA had moderate to severe sleep apnea on sleep testing that was previously undiagnosed. This huge number is due in part to the rise in obesity. Some patients resist sleep studies and even more diagnosed...

One of the great debates for decades has been what nutrients cause atherosclerosis like coronary heart disease (CHD). The major players argued back and forth have been saturated fat, mainly from animal foods, versus dietary sugars. Most studies have shown both are a risk with saturated fats found in dairy,...

The landmark research of Nathan Pritkin, Dean Ornish, MD, Caldwell Esselstyn, MD, Joel Fuhrman, MD and others has demonstrated the potential to reverse atherosclerosis in heart arteries using diet and lifestyle. The goals of reversing atherosclerosis is not commonly mentioned in conventional medicine however. A wide range of pharmaceutical agents...

If you follow the headlines, messages to the public about the value of taking a daily aspirin have been very confusing. A series of studies in 2018 showed that in a healthy adult, a daily aspirin did not confer a measurable benefit to cardiovascular health.  Last year, the U.S. Preventive...

As my clinic is the called the Kahn Center for Cardiac Longevity, there is a focus on the science of healthspan and lifespan. Measuring and halting or reversing vascular (arterial) aging is a key feature of our daily practice at the clinic. Therefore, hew scientific studies that point to strategies...

A fundamental habit for optimal health, longevity, and freedom from heart diseased is regular physical activity. Walking is the most common natural fitness habit across the world, whether as part of an occupation or soley for the purpose of health goals. It is possible people might be discouraged from walking...

High doses of cholesterol lowering statin medications are strongly recommended in patients at very high risk (VHR) of atherosclerotic cardiovascular disease (ASCVD). However, concerns about statin-associated adverse effects result in underuse of this strategy in practice. At the Kahn Center, for years we have selected low dose combination therapy in...

Chronic diseases like coronary heart disease (CHD), diabetes mellitus type 2 (DM2), cancers, and dementia are associated with over 80% of all healthcare costs and are the dominant cause of morbidity and mortality in the United States (US). Lifestyle medicine has been proposed as a potential way to address the...

Did you know that 75% cases of cardiovascular disease, such as heart attack and stroke events, are preventable? Even the feared Alzheimer’s dementia is proving to be preventable and reversible with putting a healthy lifestyle at the center of attention. Poor blood supply to the heart is as avoidable as...

My hope is that in many decades my tombstone will say "he convinced the medical system to screen for early and silent heart disease". While we strive to identify asymptomatic breast, colon, uterine, and prostate cancer, after decades of availability of inexpensive and safe heart CT scans, very few patients...

The impact of long-term endurance sport participation (on top of a healthy lifestyle) on coronary atherosclerosis and acute cardiac events remains controversial.  Some reports in the last decade have indicated that endurance athletes may have more coronary calcification, perhaps from the repeated stress of long exercise sessions. A different composition...

The scientific support for the connection between GI health and systemic health of the heart and brain is growing rapidly. The GI tract begins in the mouth and oral health as a factor in overall health is well supported. More data is need. Although tooth loss and periodontitis have been...

Atrial fibrillation (AF) is a heart rhythm disorder that is linked to an increased risk of dementia, even in stroke-free patients. Many patients with atrial fibrillation take daily oral anticoagulant (OAC) medications like warfarin or direct-acting oral agents like Xarelto. Even with OAC medications, dementia is a risk.  The impact...

A healthy lifestyle, including a healthy diet has been associated with an improvement in cardiovascular risk factors. Although olive oil (OO) is a tradtional component of the Mediterranean diet, their is some controversy over whether OO is acceptable in patients with coronary heart disease (CHD). The aim of a new...

Nature holds many secrets for health. However, Western medicine often takes a “prescription pill for every ill” approach to chronic disease. The root causes of illness — which can include lifestyle, genetics, infections and environmental toxins — are often passed over. In my integrative cardiology training, I learned to appreciate...

Ambulatory blood pressure monitoring (ABPM) provides a more comprehensive assessment than clinic blood pressure, and has been reported to better predict health outcomes than clinic or home pressure. The Kahn Center is using ABPM patch that makes monitoring simple and comfortable. Does the extra information matter? STUDYThe study aimed to...

Coronary artery disease (CAD) is the number on killer of men and women. This is particulary true in patients with diabetes mellitus, a major risk for CAD. There is a long asymptomatic period for CAD when it is a silent disease so feeling good is not proof that there is...

Extracts of licorice root has been shown to reduce low-density lipoprotein (LDL)-cholesterol oxidation in mice and humans.  Licorice root is considered one of the world’s oldest herbal remedies and comes from the root of the licorice plant (Glycyrrhiza glabra). Native to Western Asia and Southern Europe, licorice has long been...

Hypertension, or high blood pressure, increases the risk of developing cardiovascular diseases like heart attacks and stroke. Diet is a modifiable factor that can be tailored to lower blood pressure, and therefore, research must be conducted to identify foods that would maximally benefit hypertensive patients. Large-scale studies such as the...

Atherosclerosis is the narrowing of arteries due to deposits of fat and cholesterol in what is called plaque, often called coronary heart disease (CHD). While young women do have heart attacks, in general, women develop CHD later in life than men and have heart attacks at an older age than...

Strategies to REVERSE coronary artery disease plaques are sorely needed. Evidence for over 40 years has demonstrated that low-fat plant diets, mind-body practices, and exercise like walking, medication, and some supplements like aged garlic can all contribute to heart plaque reversal.  More reversal therapies are needed howevere. Coronary atheroma volume...

For the first time, the American Heart Association (AHA) arranged a panel of experts who rated 10 popular diets based on their standards for heart health and just published their findings. The ten styles of diets included: DASH-style — describes an eating pattern that’s like the Dietary Approaches to Stop Hypertension (DASH)...

Data from around the world from 2017 estimated that roughly 462 million people worldwide had type 2 diabetes (DM2) and that by 2030, that number will rise to over 540 million people with the disease. DM2 is a disease in which the body becomes unable to regulate blood sugar levels...

Cardiovascular disease rates have not dropped significantly and are contributing to a drop in overall lifestpan in the United States. Better means to judge and improve cardiovascular health (CVH) are sorely needed. The American Heart Association (AHA) recently released an updated algorithm for evaluating CVH—Life’s Essential 8 (LE8) score. Researchers...

A high intake of salt raises blood pressure and the risk of cardiovascular disease. Previous studies have reported on the association between salt intake and carotid stenosis, but the association with coronary artery disease (CAD) has not been reported. STUDY PURPOSEThe present project was aimed at studying the association between...

Background:  Coronary atherosclerosis, also known as coronary artery disease (CAD) and coronary heart disease (CHD),  may develop at an early age and remain asymptomatic and hidden for many years.  It is still not known how common silent CAD is in a general population and how risky it is.  Study Design:...

Novel fasting interventions have gained scientific and public attention. Periodic fasting has emerged as a dietary modification promoting beneficial effects on metabolic syndrome and the 5 day Fasting Mimicking Diet (Prolon) has the most scientific support. The original randomized trial was in healthy volunteers. Now a "proof of concept" study...

Dietary modification is a cornerstone of cardiovascular disease (CVD) prevention. A Mediterranean (MED) diet has been associated with a lower risk of CVD but no systematic reviews have evaluated this relationship specifically in women. As CVD is the number 1 cause of death in women, any progress in the prevention...

Cholesterol lowering (LDL-C) through lifestyle, supplements and prescription medications is necessary in many patients with proven atherosclerosis like a prior heart attacks or a high coronary calcium score on CT imaging. Many patients cannot tolerate a statin prescription due to aching, liver enzyme rises, brain fog and other issues. A...

In 2011, researchers at the Cleveland Clinic led by Stanley Hazen, MD, Ph.D, published and elegant research study proposing that a metabolite called TMAO might be produced in the human body in part from meat and egg yolks and contribute to heart disease. From that single report, there is now...

A group called SHAPE proposed in 2007 that some patients are so low risk that they do not need Rx cholesterol lowering medications like statins even if the LDL-cholesterol (LDL-C) was quite high. They suggested that a heart coronary artery calcium score (CACS) of zero bu CT was an indicator...

The "food wars",  like my appearance on the Joe Rogan Experience #1175, often focus on the risks of higher fats and the type of fats, particular high saturated fat diets, for cardiovascular diseases (CVD). For decades, added sugar has been related to higher CVD rates. Even Ancel Keys, PhD, noted...

One of the hottest trends in health promotion and the media is intermittent fasting (IF), properly defined as not eating or eating very little (fasting mimicking diet FMD) for 24 hours or more. IF extends healthspan and lifespan in rodents, and has been associated with metabolic benefits in humans, yet...

Importance  There are genetic variants that are inherited at birth and are associated with significantly lower low-density lipoprotein cholesterol (LDL-C) concentrations for life. These genetic "experiments" permit asking the question whether a lifelong lower LDL-C lowers the risks of coronary heart disease (CHD) like heart attacks. I published data like...

Proton pump inhibitors (PPIs) are widely used drugs for gastric acid–related diseases and may affect the gut microbiome.
