ABSTRACT

Objective To compare the clinical outcomes of immediate PTCA and elective PTCA on infarct related artery after spontaneous recanalization. Methods One hundred and eighteen patients with SR between January 1996 and March 2001 were enrolled. According to TIMI flow, the patients were divided into 2 study populations. The two study populations were divided into 2 groups according to immediate PTCA or elective PTCA, respectively. Results Mortality and reinfarction were similar between the 2 groups two weeks after heart attack. However, recurrent ischemic events were more frequent in elective PTCA group than in immediate PTCA group according to TIMI flow grade 2 (1/24 vs 4/12,P=0.034). Furthermore, heparin or low molecular weight heparin was prescribed more frequently in elective PTCA (4/24 vs 11/12, 3/45 vs 34/37,P
