Percutaneous transluminal coronary angioplasty after non-Q-wave infarction

Author and Disclosure Information

Abstract

Non-Q-wave infarction is associated with a significant incidence of infarction and death. We followed 52 patients who underwent percutaneous transluminal coronary angioplasty (PTCA) within three months of non-Q-wave myocardial infarction. Thirty-eight patients had single-vessel disease, 12 had double-vessel disease, and two had triple-vessel disease. A t follow-up at 28 ± 8 months, all patients were alive. Three suffered a recurrent myocardial infarction during the follow-up period. Nine underwent repeat angioplasty. Four patients had bypass surgery for recurrent symptoms. Only 25% of the patients had angina at follow-up, and all but two were in an improved functional class. PTCA may be used safely in the management of patients after non-Q-wave infarction and results in a favorable long-term prognosis.
