I've Seen Too Many Heart Attacks from THIS (Vascular Surgeon Explains)

About this video

In part one of an interview, vascular surgeon Dr. Lily Johnston explains her root-cause approach to arterial disease. She claims plaque is driven mainly by inflammation and oxidative stress damaging the artery lining, with excess blood sugar, diabetes and insulin resistance, and smoking as major sparks, and she estimates roughly 70 to 80 percent of cases involve modifiable lifestyle factors versus about 20 percent genetic predisposition. Johnston discusses testing options and the prices she quotes: a calcium score scan at about $90 to $150, carotid ultrasound thickness testing at $150 to $400, and coronary CT angiography at roughly $300 to $2,000. She also challenges, in her words, the idea that dietary cholesterol and saturated fat simply clog arteries, and closes with two actions: take a five-minute walk today and get your cardiovascular status checked.

Key takeaways

• The featured surgeon claims inflammation and oxidative stress, not fat alone, set off plaque formation
• Johnston says she uses extensive labs, including fasting insulin, inflammatory markers, ApoB, particle counts, and Lp(a), plus imaging
• Johnston gives price ranges for calcium scoring, carotid ultrasound, and coronary CT angiography as preventive tests
• Johnston claims many patients improve triglycerides, HDL, and blood pressure on a lower-carbohydrate, higher-fat approach
• Kane adds her own tip: focus on eating protein first so people naturally eat less sugar
