Single (culprit) vessel disease in octogenarians with acute myocardial infarction and unstable angina.

It is generally thought that coronary artery disease (CAD) in octogenarians would involve multiple vessels. The purpose of the current study was to determine the relative importance of single vessel disease in octogenarians with acute myocardial infarction (AMI) and unstable angina and its outcome from a revascularization procedure such as percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass grafting (CABG). Our study included 70 patients (25 men, 45 women) aged 80 or older (mean, 84.
