[Reocclusion following successful thrombolytic therapy in acute myocardial infarct].

Following successful reperfusion of the previously occluded coronary artery in acute myocardial infarction, reocclusion remains an at least partially unsolved problem. The literature reports figures between 10 and 30%. In the present study, 130 out of 543 patients with successful thrombolysis by means of intracoronary streptokinase underwent a follow-up angiography at the 3rd day (106/130, 80%) and/or 6 months (76/130, 59%) after the acute intervention. During the observation period, neither PTCA nor bypass surgery were performed. Reocclusion could be documented in 5.5% of patients at the early stage, and in 25.0% half a year later. In more than 75% of patients, who presented with a reoccluded infarct related artery, clinical evidence of reinfarction had been recorded during the follow-up period.
