Can plant-forward dietary patterns protect the heart and remodel arteries through mechanisms that standard fasting ApoB measurements fail to fully capture?
Imagine you are sitting in a small, sterile doctor’s office. The air is cool, the paper on the exam table crinkles under you, and your heart is thumping against your ribs—not from exercise, but from fear. Your doctor looks at a scan of your chest and says the words no one wants to hear: "You have a blockage."
Most people think a heart attack is like a lightning strike. One minute you are fine, and the next, everything changes. But science shows that heart disease is not a sudden accident. It is more like a slow story that takes forty or fifty years to write.
For a long time, most doctors and patients believed that heart disease was a one-way street. Once your arteries started to clog up with plaque , the goal was simply to slow down the decline. We treated it like a rust problem on an old car—you can’t really get rid of the rust; you just try to paint over it or keep it from spreading too fast. It felt like an unstoppable force of aging.But what if heart disease wasn’t a life sentence? Imagine your arteries are like a garden hose .
For decades, doctors and scientists have been locked in a "Chicken and Egg" mystery. When someone has a heart attack, their arteries are filled with two specific things: fatty buildup (lipids) and signs of a "swelling" immune response (inflammation).
Atherosclerotic cardiovascular disease (ASCVD) remains the leading global cause of mortality despite major advances in acute care. Modern preventive cardiology increasingly recognizes apolipoprotein B (ApoB)–containing lipoproteins as the necessary and causal drivers of atherosclerosis.
Can LDL Be Too Low? What PCSK9 Inhibitors Mean for Brain Health
PCSK9 inhibitors are among the most powerful cholesterol-lowering treatments available. They can lower LDL (“bad cholesterol”) by 50–60% or more—and in some cases drive LDL below 20 mg/dL.
That’s an incredible tool for preventing heart attacks and strokes. But it also raises a fair question: If the brain needs cholesterol, could LDL get “too low” and increase the risk of Alzheimer’s or dementia?
Imagine a man named Sam. Sam is the kind of person we all want to be. He runs five miles every morning, he eats plenty of colorful vegetables, and he avoids junk food. When Sam went to his yearly check-up, his doctor had great news. The doctor looked at Sam’s blood test and said, "Your numbers are perfect! Your total cholesterol is low, and your LDL looks great. Your heart is in tip-top shape."
Many people live with a quiet fear. They believe that as they get older, their heart will naturally get weaker. They think that clogged arteries are a "one-way street." Most people imagine heart disease like a car rolling down a steep hill. They think the best they can do is press the brakes to slow the car down before it crashes. They hope that by being "mostly healthy," they can delay the worst from happening.
The management of coronary artery disease (CAD) has traditionally been viewed through the lens of “risk management.” In this paradigm, pharmacological interventions such as statins and procedural approaches such as Percutaneous Coronary Intervention (PCI) or Coronary Artery Bypass Grafting (CABG) are deployed to slow the expected progression of disease. However, these approaches primarily address late-stage manifestations—the “downstream” consequences—rather than the “upstream” cellular and molecular drivers of plaque formation and instability.
Can an elite athlete have heart disease? Short answer: yes. I’m a lifelong endurance cyclist—now 65 years old - with three national records and two world records. I once believed fitness was protection.
Short answer: yes. I’m a lifelong endurance cyclist—now 65 years old—with three national records and two world records. I once believed fitness was protection. But heart disease doesn’t care how fit you are. This is how I went from five blocked arteries to another world record—and what athletes can do to protect their hearts.
To truly settle the long-running "cold war" between Dr. Loren Cordain’s Paleo camp and Dr. T. Colin Campbell’s plant-based paradigm, we have to look past the slogans and focus on the biological mechanisms of disease. For decades, we’ve been told it’s a binary choice. But the research from late 2024 and 2025 has given us a far more interesting "middle way." One side holds the crown for heart health, while the other was right to sound the alarm about food quality all along.
Atherosclerosis is a chronic, progressive vascular condition traditionally managed by interventions aimed at slowing its advancement.1 The measurable reversal of this condition—defined as structural regression—is the highest therapeutic outcome in cardiovascular disease management.2 Regression is evidenced angiographically by an increase in Minimal Lumen Diameter (MLD) or a decrease in Percent Diameter Stenosis ( %DS ).
A Practical, Evidence-Based Q&A Inspired by the Ornish Debate
Introduction: Why This Question Won’t Go Away
Dean Ornish has claimed for decades that intensive lifestyle change—especially an almost-vegan, very low-fat diet—can not only prevent but actually reverse heart disease.
Imagine a world-class runner. This person races through marathons, eats what they believe is a "perfect" diet, and feels like they are in the best shape of their life. Then, without warning, they suffer a heart attack. This is the "fit but not immune" paradox. It is a secret fear for many active people.
Coronary atherosclerosis can regress under defined conditions. Serial intravascular ultrasound (IVUS) and coronary computed tomography angiography (CCTA) studies show that intensive low-density lipoprotein cholesterol (LDL-C) reduction via high-intensity statins, PCSK9 inhibitors, and, in selected settings, icosapent ethyl, can shrink plaque volume. Paradoxically, the arterial lumen often remains unchanged or may even narrow due to reverse or constrictive remodeling. Complementary lifestyle trials such as the Ornish study demonstrated angiographic regression driven primarily by improved endothelial and vasomotor function.
Training Didn’t Help. My name is Dr. Peter Megdal, and this is my story of curing heart disease. In 2010 I noticed a steep drop in my power output during races. Racing cyclists have power meters that are attached to our bikes so we can accurately measure how strong we are in training and competitions. I was 50 years old, and my coach and my friends all told me that this was because I was getting older, but I knew a 15% drop was pretty steep and not normal especially in just one or two years.
