Predictors of MACE in univariate and multivariate Cox regression analysis
| Univariate | Stepwise multivariate | |||
|---|---|---|---|---|
| Variable | Hazard ratio (95 % CI) | P | Hazard ratio (95 % CI) | P |
| Smoker | 2.17 (1.14-4.13) | 0.02 | - | - |
| Number of diseased vessel | 1.34 (1.01-1.79) | 0.04 | - | - |
| Peak CK | 1.01 (1.00-1.02) | 0.03 | - | - |
| TIMI-risk score | 1.43 (1.27-1.58) | <0.001 | 1.35 (1.19-1.53) | <0.001 |
| LV ejection fraction < median | 3.18 (1.70-5.95) | <0.001 | - | - |
| LVGFI < median | 3.95 (2.03-7.67) | <0.001 | 2.84 (1.34-6.00) | 0.006 |
CI = confidence interval, CK = creatine kinase, LV = left ventricular, LVGFI = left ventricular global function index, TIMI = Thrombolysis In Myocardial Infarction
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
