From: Left ventricular global function index assessed by cardiovascular magnetic resonance for the prediction of cardiovascular events in ST-elevation myocardial infarction

  Univariate Stepwise multivariate

LVGFI < median 3.95 (2.03-7.67) <0.001 2.84 (1.34-6.00) 0.006
  1. CI = confidence interval, CK = creatine kinase, LV = left ventricular, LVGFI = left ventricular global function index, TIMI = Thrombolysis In Myocardial Infarction
  2. Myocardial salvage, IS and MO were not included in the Cox regression model as the main purpose of this study was to identify an independent predictive value of the LVGFI in comparison to the LVEF
