title: [PTCA in the acute state of myocardial infarct: hospital course of 785 consecutive patients].
abstract: Rapid reperfusion of the occluded coronary artery is essential for the reduction of mortality and complications of acute myocardial infarctions. Intravenous thrombolytic therapy using various thrombolytic substances has proven to be effective and easy to perform and has gained widespread acceptance for treatment of acute myocardial infarction. Because of several contraindications, as well as failure to achieve patency of the infarcted vessel in 25-30% of patients, severe bleeding complications, a time interval of 6 or more hours after suspected onset of myocardial infarction, and a high rate of recurrent ischemia, this treatment is currently limited to a small percentage of patients with acute myocardial infarction. Immediate percutaneous transluminal coronary angioplasty (PTCA) can be applied to nearly every patient presenting with acute myocardial infarction. Therefore, we offer immediate PTCA as the primary treatment to all of our patients presenting with acute myocardial infarction. Between January 1987 and December 1991, immediate PTCA was performed in 785 of 903 (87%) consecutive patients (aged 23-86 years, mean 61 +/- 10). 82% (640/785) of the patients were men. Anterior myocardial infarction was present in 372 patients (47%), inferior infarction in 413 patients (53%). 245 patients (31%) had 1-vessel disease, 221 patients (28%) two-vessel disease and 319 patients (41%) had three-vessel disease. 97 patients (12%) were in cardiogenic shock. In 675/785 patients (86%) the infarct related vessel was occluded (TIMI < or = 1). 86% of patients had a patent infarct related vessel (TIMI > or = 2) leaving the catheterization laboratory. The overall in-hospital mortality was 6.9% (54/785 patients), after exclusion of high-risk patients (age > 75 years, cardiogenic shock, PTCA under cardiopulmonary resuscitation) mortality decreased to 2.5%. Recurrent ischemia necessitated immediate repeat PTCA in 4.4% of the patients, in 8.1% of patients another elective PTCA was performed during hospitalization and 9.7% of patients were sent to surgery (4.0% on an emergency basis). 87% of all patients presenting with acute myocardial infarction could be treated successfully with immediate PTCA. With respect to the severely ill group of patients the primary success rate is high, the rate of reocclusion is low, and the overall mortality is extremely low. From our data, it is obvious that immediate PTCA compared to thrombolytic therapy is the superior treatment of myocardial infarction.
