摘要

resent the clinical and angiographic features oftwo post-menopausal females who presented wiih anterior non-Q myocardial mfarction. The first patient had frequent episodes of post-infarct angina and coronary angiography reveakd isolated left main coronary ostial Stenosis; she was well and asymptomatic after coronary artery bypass surgery. The second patient had no post-mfarct angina with no inducible ischemia on maximal exercise stress testing, and routine coronary angiography revealed catheter tip left main coronary artery spasm after reversal of the "ostial Stenosis" by sublingual glyceryl trinitrate, and a minor plaque m the mid-left anterior descending artery.
