CABG = coronary artery bypass grafting; MT = medical therapy; PCI = percutaneous coronary intervention.

  • These included patients with any arrhythmia, untypical chest discomfort, or dyspnea on effort, and asymptomatic patients with any abnormal cardiac findings on mass examination, among others. Objective myocardial ischemia (substantial changes in ST-segment depression or T-wave inversion on a resting electrocardiogram, or inducible ischemia with either exercise or pharmacologic vasodilator stress) was found in all of these patients, after which coronary arteriography showed 1- or 2-vessel disease in each.
