Multivariate analyses of predictors for cardiac mortality and MACE-free survival of patients with CTO.
| Variable | HR (95% CI) | P value |
|---|---|---|
| MACE | ||
| CTO-PCI successful | 0.58 (0.32–0.94) | <0.01 |
| Prior MI | 3.89 (1.95–7.84) | <0.05 |
| CKD | 3.51 (1.52–7.87) | <0.01 |
| LVEF (per-10% increment) | 0.94 (0.88–0.99) | <0.05 |
| Mortality | ||
| CTO-PCI successful | 0.35 (0.19–0.68) | <0.01 |
| Age | 1.08 (1.02–1.11) | <0.01 |
| Prior MI | 2.31 (0.73–7.35) | 0.16 |
| CKD | 7.18 (2.95–17.40) | <0.01 |
| LVEF (per-10% increment) | 0.87 (0.77–0.93) | <0.01 |
CI: confidence interval; HR: hazard ratio; CTO: chronic total occlusion; PCI: percutaneous coronary intervention; MI: myocardial infarction; CKD: chronic kidney disease; LVEF: left ventricular ejection fraction.
