RESUMO
In 807 consecutive patients from the Chilean National Registry of Acute Myocardial Infarction we analyzed the resolution of chest pain and ST segment elevation over 50 percent within the first 90 min, abrupt CK rise within 8 h and T wave inversion in infarct related EKG leads within the first 24 h after thrombolysis. Global in-hospital mortality was 12.1 percent. Mortality of patients with the presence of 3 or 4 markers of coronary artery patency was 5.1 percent, in those with resolution of ST elevation and abrupt CK rise was 6.25 percent and in those with T wave inversion it was 3.9 percent (p<0.001). Multivariate analysis, adjusted by age, gender, risk factors, Killip class and infarct location showed that early T wave inversion was the better predictor of a low in-hospital mortality and its combination with other markers of coronary artery patency did not increase its prognostic power. Early CK rise and the presence of 3 out of 4 reperfusion criteria were also independent predictors of a low mortality. Non invasive markers of coronary artery patency are associated with a lower in-hospital mortality and may serve as surrogate end points in clinical trials
