Dr Scott Murray – Is IVUS Plaque ‘Regression’ Just Measurement Noise?

Dr Scott Murray – Is IVUS Plaque ‘Regression’ Just Measurement Noise?

In this episode of The Feldman Protocol, how much does metabolic health shape cardiovascular risk beyond what standard lipid markers can reveal? Dave Feldman sits down with Scott Murray (MD), a UK-based interventional cardiologist, to explore plaque imaging and its limitations, the role of visceral and perivascular fat in heart disease, the lipid energy model and lean mass hyper-responders, cardiac fuel metabolism and heart failure with preserved ejection fraction, and the challenges of conducting and interpreting cardiovascular trials.
