Text: On the basis of 21 potential covariates fitted simultaneously, multivariable adjusted hazard ratios showed that age [hazard ratio 1. 03, 95 % confidence interval (CI) 1. 01-1. 07, P = 0. 01], chronic renal failure (hazard ratio 3. 21, 95 % CI 1. 02-10. 10, P = 0. 05), pre-PCI values of creatine kinase-myocardial band (CK-MB) (hazard ratio 1. 002, 95 % CI 1. 0002-1. 0054, P = 0. 04), intra-aortic balloon pump (hazard ratio 5. 88, 95 % CI 12. 33-14. 85, P = 0. 0002) and the presence of eptifibatide (hazard ratio 1. 85, 95 % CI 1. 04-3. 29, P = 0. 04) were significant risk factors whereas thrombolysis by tenecteplase (hazard ratio 0. 19, 95 % CI 0. 05-0. 69, P = 0. 01) was a significant protector.
