title: Percutaneous transluminal coronary angioplasty without thrombolytic therapy in acute myocardial infarction.
abstract: Percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial infarction (AMI) was performed in 42 patients (37 males, 5 females, average age 53 years). Recanalization of the stenosed or occluded infarction-related coronary artery was achieved within the first 14 to 50 min from the start of catheterization in 95% of cases. Three patients were transferred for emergency coronary bypass graft surgery (CABG) because of major multiple coronary lesions, immediately after angiographically successful PTCA. One of the patients died in cardiogenic shock. Four patients died between days 5 to 15 of hospitalization. Repeat coronary angiography was done in 27 of the 37 survivors at a mean interval of 2.5 months after AMI. Total reocclusion was found in 6 patients. The recanalized coronary artery had prevented its patency in 78% of the cases; restenosis was found in 5 patients, and was successfully dealt with renewed angioplasty in 3 patients. While the ejection fraction (EF) had remained largely unchanged, there was some improving tendency of left ventricular segmental kinetics, particularly in case of anterior wall infarction. PTCA without thrombolytic therapy seems to provide an effective and relatively prompt recanalizing procedure in the complex management of AMI.
