| Ethnicity (Asian) | White | 1.19 (1.09–1.30) | 1.33 (1.14–1.55) |
| Cardiogenic shock | No cardiogenic shock | 5.56 (4.40–7.04) | 4.31 (2.91–6.37) |
| Diabetic | Nondiabetic | 1.28 (1.17–1.40) | 1.36 (1.17–1.58) |
| Previous MI | No previous MI | 1.45 (1.32–1.60) | 1.30 (1.10–1.52) |
| Previous PCI | No previous PCI | 1.03 (0.94–1.12) | 1.05 (0.92–1.16) |
| Hypertension | No hypertension | 1.16 (1.05–1.28) | 1.03 (0.87–1.23) |

| eGFR<60 mL/min per 1.73 m2 | eGFR>60 | 3.19 (2.81–3.62) | 2.12 (1.70–2.65) |
| EF<35% | EF>35% | 2.19 (1.87–2.57) | 1.74 (1.43–2.11) |
| GP IIb/IIIa inhibitor use | No GP IIb/IIIa inhibitor use | 0.94 (0.80–1.04) | 0.96 (0.83–1.26) |
| Procedural success | Procedural failure | 0.83 (0.67–1.03) | 0.76 (0.60–0.89) |
| Access route (radial) | Femoral | 0.97 (0.87–1.13) | 0.93 (0.87–0.99) |
| Bypass‐graft intervention | Native‐vessel intervention | 1.38, 95% (1.08–1.81) | 1.33 (1.03–1.71) |
The overall sample size included 97.3% of the patients in this analysis. CABG indicates coronary artery bypass grafting; EF, ejection fraction; eGFR, estimated glomerular filtration rate; GP IIb/IIIa, glycoprotein IIb/IIIa; MI, myocardial infarction; and PCI, percutaneous coronary intervention.
