Peter argues for the importance of paying attention to and understanding ASCVD given its ubiquity and inevitability. He goes into great detail about the development of atherosclerosis and how it can take hold at a very early age, the role of cholesterol, and the causal factors of ASCVD that determine prevention strategies. Additionally, he discusses the important metrics and biomarkers found in blood work, as well as diagnostic tests such as coronary artery calcium scores (CAC) and CT angiograms which help to determine the level of arterial damage present. Finally, Peter lays out the keys to understanding and interpreting calcium scores before wrapping up the conversation with his key takeaways regarding prevention.
