On this episode of Infinite Health, host and interventional cardiologist Dr. Arasi Maran dives deep into one of medicine's most debated and misunderstood topics: cholesterol. With the release of the 2026 American College of Cardiology and American Heart Association guidelines, the conversation has never been more relevant. Together, they unpack why cholesterol became the “villain” of heart health, explore the real science behind cholesterol’s role in the body, and reveal how public messaging, dietary trends, and blockbuster drugs simplified a complex issue into good versus bad numbers.

But there’s more to cholesterol than a single lab value. Dr. Arasi Maran discusses the nuances that matter, like the importance of LDL particle size, the hidden risk of lipoprotein(a), and why understanding your triglycerides could be a game-changer. Whether you’re a patient, a clinician, or just trying to make sense of your health data, this episode is full of actionable insights about lab interpretations, lifetime risk, new drug options, and how AI and emerging diagnostics are transforming the landscape of cardiovascular care.
