Abstract
A series of 295 coronary bypass patients who had early and late postoperative coronary angiography included 6 cases (2%) whose grafts had become occluded. These patients were followed up using functional classification and repeated exercise testing. In 3 patients the functional classification improved early after surgery (.ltoreq. 1 yr), with improved exercise capacity in 2. Two patients had perioperative myocardial infarction. During further follow-up (3-8 yr after surgery) only 1 patient who improved initially retained the improved capacity. There were 3 deaths. Some unsuccessfully revascularized patients exhibit initial improvement which is only exceptionally maintained over longer periods. The likely explanation for pain relief is perioperative myocardial infarction.
