Predictors of short term clinical and angiographic outcome after coronary angioplasty for acute myocardial infarction

Coronary angioplasty is an effective method to achieve myocardial reperfusion in acute myocardial infarction (AMI). We reviewed our experience in 132 patients (pts) who underwent percutaneous transluminal coronary angioplasty (PTCA) of a totally occluded infarct-related artery (IRA) within 24 h after the onset of symptoms (mean delay 10 +/- 7 h), in order to identify the predictors of primary success and of major complications. PTCA was successfully performed in 113 patients (86%). Failure without complications occurred in 12 patients (8.4%); untoward events (death and emergency CABG) occurred in seven patients (5.3%). Pts in the failure group were more likely to have cardiogenic shock (53 vs. 8.8%, P < .0005), longer time to reperfusion (15 +/- 6 vs. 9 +/- 6 h, P < .0005), lower ejection fraction (EF) (42 +/- 16 vs. 54 +/- 12%, P < .0005), multivessel disease (74 vs. 43%, P < .03), and a smaller IRA diameter (2.8 +/- 0.6 vs. 3.1 +/- 0.6 mm, P < .03). Sex, age, previous bypass surgery, previous thrombolytic treatment, IRA, and infarct location were similar in both groups. Absence of cardiogenic shock (P < .0001), decreasing time to reperfusion (P < .005) and increasing EF (P < .02) were independent predictors of successful PTCA...Continue Reading
