Dr. Charles Mok explains how carotid intima-media thickness (CIMT) measures your cardiovascular age, which can be younger or older than your actual age. A younger cardiovascular age means low risk of heart attack or stroke over the next decade. He argues that standard blood markers like cholesterol and LDL are poor predictors and don't track real improvement.

If your CIMT shows that your cardiovascular age is much younger than you are, you're in pretty good shape. Keep doing what you're doing. You're not going to have a heart attack or stroke in the near future. When I mean near future, I mean years to a decade. If your CIMT age shows that you're older than average for your age, you're more likely to have a cardiovascular event in the future. But in general, if you were, let's say, 50 and you've got a cardiovascular age of 65, you're getting much closer to the heart attack than somebody at 50 who has cardiovascular age of 50. And we could do intervention. We send people to the local doctor that works on reversing cardiac age is actually very straightforward. How you reverse cardiovascular age. It's not going to be screened through cholesterol and lipids and triglycerides and ldl. Those are not very useful tests or good markers that you're going in the right direction if you're treating those markers. But it's not a good marker or predictor of cardiovascular disease.
