Abstract

This study evaluates the influence of early revascularization (with percutaneous transluminal coronary angioplasty (PTCA) and coronary surgery) on short- and long-term survival in patients with cardiogenic shock complicating acute myocardial infarction (AMI). In-hospital and 6-month survival were retrospectively determined on day 193 (65-270, median +/- 25th and 75th percentiles) in 87 patients who either underwent early invasive reperfusion (group A, n=60) or those who were treated conservatively (group B, n=27). In-hospital mortality was 37% in group A and 56% in group B (P=0.192). Six-month mortality was statistically lower in group A than in group B (30 patients (50%) compared with 25 patients (93%), P=0.005). Being a woman and older age were found to be factors increasing mortality. Lower mortality in the long term was strongly associated with revascularization (odds ratio=0.08, 95% confidence interval=1.54-109). PTCA was found to be an independent predictor of long-term survival (odds ratio= 0.22, 95% confidence interval=0.049-1.00, P=0.050), by multiple logistic regression. In conclusion, this study suggests that early revascularization improves long-term survival of patients with cardiogenic shock complicating AMI, even...Continue Reading
