Episode 493: The Top 3 Dietary Predictors of Cardiac Death Worldwide
Heart Doc VIP with Dr. Joel Kahn
This week, Dr. Kahn reviews new data from the Global Burden of Disease study analyzing the relationship between diet and death from heart disease. In 2023, an estimated 5.9 million deaths worldwide were linked to poor dietary choices, led by excessive sodium intake and insufficient consumption of fruit and whole grains. It’s a fascinating and important study with clear takeaways. Other topics include stents for angina, causes of sudden cardiac death, daytime napping and health outcomes, plastic-free diets, PCSK9 inhibitors vs. statins, calcium supplements, and the purity of fish oil samples....

Episode 492: Does the Shingles Vaccine Reduce Heart and Brain Disease?
Heart Doc VIP with Dr. Joel Kahn
This week, Dr. Kahn addresses a topic gaining attention in the media: whether taking the shingles vaccine (Shingrix in the USA) may reduce the risk of heart events and dementia. Multiple studies suggest this could be true, although no randomized trials have been performed to confirm it. Furthermore, most of these studies focus on a version of the vaccine that was discontinued in the U.S. in 2020 (Zostavax), making the assumption that Shingrix provides the same benefits somewhat speculative. This is a topic worth discussing with your primary care team. Other topics include controversies in...

Episode 491: Heart Disease in Masters Athletes: What to Do?
Heart Doc VIP with Dr. Joel Kahn
This week, Dr. Kahn dives into heart disease in “masters athletes,” highly active individuals over 35 who train and compete at a serious level. Despite their fitness, research shows they may face equal—or even higher—rates of cardiovascular issues like arrhythmias, coronary artery disease, and aortic dilation. A new consensus statement breaks down what to watch for and recommends advanced screening like EKGs, coronary calcium scans, and detailed blood work. Beyond that, Dr. Kahn shares insights from his own recent mitral valve surgery recovery and explores why common heart risk...

Bonus Episode: Why a CIMT Ultrasound Is a Must-Have Examination with Joseph Ence
Heart Doc VIP with Dr. Joel Kahn
What if a quick, painless ultrasound could reveal your true vascular age? In this bonus episode of Heart Doc VIP, host Dr. Joel Kahn sits down with Joseph Ence to discuss CIMT (carotid intima-media thickness)—a simple, non-invasive test used in over 5,000 research studies over the past 20+ years to measure plaque and thickness in the carotid arteries. Safe and radiation-free, this ultrasound provides valuable insight into your cardiovascular health by estimating your “vascular age.” They also explore how targeted interventions—like lifestyle changes, supplements, and...

Episode 487: The Role of Diet, Blood Pressure, and Hormones in Dementia
Heart Doc VIP with Dr. Joel Kahn
This week, Dr. Kahn breaks down new research on dementia risk, including the roles of high blood pressure and early menopause. He looks at conflicting studies on red meat and ApoE4, which pretty much sums up nutrition science: one study says yes, another says absolutely not. For now, limiting red meat—especially processed—is still the safest move. He also covers the risks of skipping breakfast, calcium CT scoring for elevated lipoprotein(a), tooth loss and heart disease, long-term clopidogrel use after stents, ultraprocessed foods, Repatha and statins, Cleerly AI scans, micro-exercise...
info_outlineThis week, Dr. Kahn dives into four new research papers on omega-3 fatty acids and their impact on heart and brain health. The discussion highlights several eye-opening findings, including reduced atrial fibrillation risk and improved cardiovascular outcomes in patients undergoing hemodialysis. Dr. Kahn also explains how omega-3 intake supports brain health and why the “right” dose depends on the specific condition being addressed. Food sources, fish oil, algae-based supplements, and ahiflower are compared as practical ways to reach optimal omega-3 levels.
Additional topics in this episode include newly approved AI software for early detection of heart disease, the role of statins in patients with type 2 diabetes, the science—and hype—around NAD+ boosters, and emerging data on Prolon fasting for Crohn’s disease. Dr. Kahn also reviews concerning research on heart rhythm risks associated with high-intensity endurance exercise in athletes over the age of 50.
As always, the episode blends cutting-edge research with real-world clinical insight to help clarify what actually matters for long-term heart health.

More About This Episode
This episode takes a deeper look at why omega-3 blood levels matter more than simply taking a supplement. Dr. Kahn reviews large population studies linking higher omega-3 levels to lower risks of atrial fibrillation, early-onset dementia, and major cardiovascular events, including in high-risk groups such as patients on hemodialysis. The key takeaway: testing omega-3 status and personalizing intake may be far more effective than a one-size-fits-all approach.
Beyond omega-3s, Dr. Kahn explores several timely and surprising topics, including AI-enhanced CT scan technology designed to detect silent heart disease without additional radiation, real-world data on statin benefits in patients with type 2 diabetes, and why costly NAD+ supplements may ultimately function as a form of vitamin B3. The episode also examines new evidence on fasting-mimicking diets for Crohn’s disease and potential heart rhythm risks in high-level endurance athletes over 50.
Throughout the discussion, Dr. Kahn emphasizes practical, evidence-based steps patients can review with their physicians, including omega-3 blood testing, coronary calcium scoring, and tailoring lifestyle and supplement strategies to individual risk factors.
