Relation of mortality of primary angioplasty during acute myocardial infarction to door-to-thrombolysis in myocardial infarction (TIMI) time



Relation of mortality of primary angioplasty during acute myocardial infarction to door-to-thrombolysis in myocardial infarction (TIMI) time



American Journal of Cardiology 91(12): 1401-1405



For primary angioplasty of acute myocardial infarction (AMI), the relation of treatment benefit and time has been debated. The present study aimed to evaluate, in a single-center cohort of patients with ST-segment elevation AMI, which time intervals were carefully and consistently measured, and the relations among ischemic time, in-hospital delays, and in-hospital survival. We included 499 patients (mean age 59 years; 80% men) who underwent successful primary percutaneous transluminal coronary angioplasty (PTCA) for AMI admitted < or =6 hours after symptom onset. The population was divided into tertiles with respect to time between onset of symptoms and admission, onset of symptoms to Thrombolysis In Myocardial Infarction (TIMI) grade 3 flow, and time from admission to TIMI grade 3 flow. Univariate analysis followed by multiple logistic regression was performed using the variables linked to mortality in the univariate analysis to assess the relation between predictor variables and in-hospital mortality. The in-hospital mortality rate was 3.2%. There was no significant relation between the various tertiles of time intervals and in-hospital mortality. After linear logistic regression, only age (odds ratio [OR] 1.79 per 10 years), female gender (OR 3.56), and door-to-TIMI 3 time (OR 1.27 per 15 minutes) were independently correlated with in-hospital mortality.
