The character of chest pain and results of exercise electrocardiograms were correlated with coronary cine-angiographic findings in 50 patients with suspected coronary artery disease. Twelve of 14 patients with typical angina and abnormal exercise electrocardiograms had occlusive disease shown by coronary arteriography. In ten of 13 patients with atypical angina and normal exercise electrocardiograms, no arterial disease was found. The predictive value of angina in conjunction with the exercise electrocardiogram diminished by about one-half in the remaining 23 patients in whom these two parameters varied in opposite directions. Guidelines for selection of patients with suspected coronary artery disease for coronary arteriography are identified.
