Multivariate logistic regression analysis was used to identify clinical predictors at admission of in-hospital mortality among the 4 ECG patterns and variables associated (p < 0.05) with this outcome on univariate analysis. In ST-segment elevation myocardial infarction, STE-aVR is caused by transmural ischemia in the basal septum, often resulting from obstruction of the left main or the proximal left anterior descending coronary artery.
