Independent Predictors of 3-Year Cardiac Mortality

Risk FactorHR (95% CI)p Value
Age (per 5 yrs)1.33 (1.21–1.45)<0.001
White blood cell count (per 109 cells/l)1.12 (1.07–1.18)<0.001
Serum creatinine (per 0.1 mg/dl)1.11 (1.06–1.16)<0.001
Killip class 2–42.28 (1.52–3.42)<0.001
PCI of the left main artery6.15 (2.26–16.76)<0.001
PCI of the left anterior descending artery1.65 (1.13–2.42)0.01
Diabetes, medically-treated1.58 (1.09–2.29)0.02
Hemoglobin (per g/dl)0.89 (0.79–1.00)0.04
Bivalirudin (vs. UFH+GPI)0.56 (0.40–0.80)0.001

Other variables in the model that were not significantly associated with cardiac mortality: current smoker, female sex, prior myocardial infarction, and number of vessels treated.

CI = confidence interval; GPI = glycoprotein IIb/IIIa inhibitor; HR = hazard ratio; PCI = percutaneous coronary intervention; UFH = unfractionated heparin.
