EPISODE DESCRIPTION
Tom Dayspring is a world-renowned expert in clinical lipidology & a previous guest on The Drive. In this episode, Tom explores the foundations of atherosclerosis & why atherosclerotic cardiovascular disease (ASCVD) is the leading cause of death worldwide for both men & women. He examines how the disease develops from a pathological perspective & discusses key risk factors, including often-overlooked contributors such as insulin resistance & chronic kidney disease. He breaks down the complexities of cholesterol & lipoproteins with an in-depth discussion on the critical role of apolipoprotein B (apoB) in the development of atherosclerosis. He covers the importance of testing various biomarkers, the impact of nutrition on lipid levels, & the vital role of cholesterol in brain health, including how cholesterol is synthesized & managed in the brain, how it differs from cholesterol regulation in the rest of the body, & how pharmacological interventions can influence brain cholesterol metabolism.

EPISODE SUMMARY
In this episode of Peter Attia MD, featuring Peter Attia and Tom Dayspring, 334 - Cardiovascular disease, the number one killer: development, biomarkers, apoB, and more explores tom Dayspring and Peter Attia Explain ApoB, Lp(a), and Atherosclerosis Dayspring describes atherosclerosis as the deposition of cholesterol in the artery wall by apoB-containing particles, a process that begins in childhood or even in utero and takes decades to cause symptoms.
