title: The roles for coronary surgery and angioplasty in the management of patients with stable angina: evidence and decision making.
abstract: Evidence from the randomized studies of coronary surgery suggests that patients who benefit from surgery in terms of improved survival are those with left main stem stenosis, triple vessel coronary artery disease, impaired left ventricular function or higher angina class. Patients currently undergoing surgery are in general older, with more severe angina, more comorbidity and more extensive coronary disease as compared with the population randomized in the earlier studies. Angioplasty has been shown to improve symptoms and to reduce the need for surgery in certain patients. Recent changes in procedural techniques and adjunctive therapies have reduced the number of acute complications and the rate of restenosis. However, recent evidence suggests that some patients with mild angina (< class 2) or good exercise tolerance may not benefit as much from angioplasty as other patients with more severe angina.
