Plaque reversal is one of the most debated topics in preventive cardiology, so in this video I react to Dr. Kevin Ham’s CAST protocol for plaque reversal: Causes, Adding Cures, Strengthening the Body, and Training the Mind and Body.

Overall, I think this is a thoughtful framework and I agree with much of it. But as a vascular surgeon who treats advanced atherosclerosis, I also add some nuance around what “plaque reversal” really means, what may be missing from this conversation, and where I’d want more granularity in a real-world cardiovascular prevention plan.

We talk about the causes of plaque buildup, metabolic health, lifestyle change, cardiovascular risk reduction, and the difference between improving risk factors versus actually changing plaque biology. I also share where I think protocols like this can be helpful—and where they risk oversimplifying atherosclerosis.

If you’re trying to understand plaque reversal, atherosclerosis, heart disease prevention, metabolic health, LDL, ApoB, inflammation, insulin resistance, and cardiovascular risk, this video will help you think more clearly about the problem.

Let me know in the comments: Do you think “plaque reversal” is a useful term, or does it create more confusion than clarity?
