A viewer asks: “Dr. Bernard Lown, a Harvard cardiologist in the 1980s, criticized the rapid rise of surgical Coronary Artery Bypass Grafts (CABG), noting 20–40% were potentially avoidable, especially in stable angina, and many patients had uncertain survival benefit. He advocated medical therapy—nitrates, beta-blockers, lifestyle changes—for symptom control. How accurate is it to say that in 2026, evidence-based guidelines and trials have reduced avoidable CABG to <10% for high-risk, guideline-selected patients, and that for low-risk, stable patients, surgery rarely improves survival, and that beta-blockers, nitrates, ACE inhibitors, lifestyle changes are to be preferred?”109 views0 answers0 votes
