Dr KK Answers: Which is better coronary artery bypass surgery or angioplasty for angina relief?

A prospective quality of life sub study of the SYNTAX trial of patients with three vessel or left main coronary artery blockage compared the relief of angina after the bypass or angioplasty. At 12 months, both interventions were associated with substantial relief of angina, although there was a statistically significant lower angina frequency with bypass surgery.
