The natural history of angina and the influence of aortocoronary saphenous vein bypass grafting on the relief of symptoms and survival are reviewed. Indications and contraindications for coronary surgery and the complications and results of operation are discussed. Coronary artery surgery is occasionally indicated in situations other than angina, such as in selected cases of unstable angina, arrhythmias and acute myocardial infarction.
