Summary
Heart disease kills one person every 40 seconds. That number hasn’t changed in 30 years. Dr. John Osborne, a preventive cardiologist with two doctorates and 29 years in practice, has spent his career on a single question: why do we screen for cancers that kill a few percent of us and do nothing for the disease that kills 40%? In this episode, Jeremy and Jason sit down with Dr. Osborne to get the real story on cardiac CT with AI — the imaging technology that can detect, quantify, and track arterial plaque at sub-millimeter resolution, years before symptoms appear. If you track your bloodwork, wear a fitness device, or consider yourself health-forward — this is the conversation that fills the gap nobody warned you about.Guest Link:https://clearcardio.com/Key Moments:00:00 — Dr. Osborne’s case for preventive cardiology: why heart disease is the most under-screened killer02:43 — How cardiac CT evolved from "iPhone 0.5" to the 2026-era AI-powered tool he uses today05:35 — Why he gave up stress tests and heart caths in 2005 and never looked back08:16 — What AI actually adds: seeing and quantifying plaque invisible to the human eye, down to 0.1 cubic millimeters10:13 — When insurance pays for cardiac CT — and when it doesn’t (the preventive gray zone)14:50 — The “cardiac colonoscopy” concept: the case for screening before symptoms, not after18:11 — Coronary artery calcium score: the accessible $100 starting point, and what it can and can’t tell you31:54 — Lifestyle essentials: the 50% of risk that’s modifiable regardless of genetics35:00 — Family history decoded: why your sibling’s heart history matters more than your parents’36:12 — Nicotine myth-busting: Dr. Osborne on the "health guru" nicotine fad and why he thinks it’s dangerous38:05 — Supplements under scrutiny: natokinase, fish oil, red yeast rice — what the actual RCT data says
