Episode notes

Heart disease doesn’t start when you’re older, it starts early, often without symptoms.

In this episode, I speak with Dr. Laurence Sperling, one of the world’s leading experts in preventive cardiology, to explore how to catch heart disease early and stop it in its tracks. We cover cholesterol, blood pressure, calcium scores, lifestyle, and more. This is one of the most practical, empowering episodes on heart health I’ve ever recorded.

What we cover:

Early detection and the true origins of atherosclerosis
How low your cholesterol and blood pressure should really be
Understanding ApoB, Lp(a), and genetic risk
When it’s worth getting a CT scan
Lifestyle and medical interventions that actually work
