Preventive cardiology, exercise, nutrition, stress, and longevity with Dr. Ross Walker

This podcast explores practical ways to protect your heart and support healthy aging. Dr. Paul Taylor talks with preventive cardiologist Dr. Ross Walker about the everyday habits that shape cardiovascular health, how to make sense of cholesterol and other risk markers, and where tests, medication, and supplements can help. Together, they cut through common health claims and discuss exercise, stress, diet, and emerging approaches to preventing heart disease.

The conversation focuses on practical prevention rather than late-stage treatment, with an emphasis on how much heart disease risk can be reduced before medication is considered. Ross explains what he thinks about cholesterol, coronary calcium scoring, statins, LP(a), MTHFR, and the future of cardiovascular medicine. It’s a wide-ranging, practical discussion for anyone interested in health span, not just lifespan.
