Patients with chest pain and normal coronary angiograms have excellent long-term survival and are unlikely over the ensuing years to develop clinically significant atherosclerotic coronary artery disease. Specifically, of the 17 subjects with a previously normal coronary angiogram who had repeat angiography an average of almost 9 years later, 15 showed no appearance of coronary artery disease and 2 developed single-vessel coronary artery disease, 1 of whom had a myocardial infarction.
