Table 2 Predictors of 1 and 3 year mortality by univariate Cox proportional hazard analysis.

From: The importance of left ventricular function for long-term outcome after primary percutaneous coronary intervention

1 year mortality   
Characteristics Hazard ratio (95% CI) p
Age, per 10 years increase 2.00 (1.35 – 2.97) 0.001
Previous MI 2.91 (1.16 – 7.28) 0.023
Previous PCI 9.58 (4.13 – 22.21) < 0.001
Max CK, per 500 U/l increase 1.01 (1.00 – 1.02) 0.050
Max CK-MB, per 50 U/l increase 1.09 (1.01 – 1.18) 0.039
LVEF, per 5 % decrease 1.47 (1.25 – 1.73) < 0.001
3 year mortality   
Characteristics Hazard ratio (95% CI) p
Age, per 10 years increase 1.63 (1.25 – 2.14) < 0.001
Previous MI 2.19 (1.06 – 4.52) 0.035
Previous PCI 5.16 (2.50 – 10.7) < 0.001
Previous CABG 3.27 (1.17 – 9.10) 0.024
Multi-vessel disease 1.50 (1.06 – 2.11) 0.021
Killip class, per class increase 1.73 (1.08 – 2.75) 0.022
Max CK, per 500 U/l increase 1.01 (1.00 – 1.02) 0.040
Max CK-MB, per 50 U/l increase 1.07 (1.01 – 1.14) 0.020
LVEF, per 5 % decrease 1.29 (1.15 – 1.46) < 0.001
  1. CABG = coronary artery bypass grafting
  2. CK = creatin kinase
  3. CK-MB = creatin kinase myoglobin binding
  4. LVEF = left ventricular ejection fraction
  5. MI = myocardial infarction
  6. PCI = percutaneous coronary intervention
