Independent Predictors of POCO in Weighted Sample
| Adjusted HRa | 95% CI | P Value | |
|---|---|---|---|
| Non‐CKD group | |||
| Complete revascularization | 0.77 | 0.62 to 0.95 | 0.015 |
| Age (each 1 y) | 1.01 | 1.01 to 1.02 | 0.003 |
| Previous CVA | 1.87 | 1.27 to 2.76 | 0.002 |
| Previous PCI | 1.32 | 1.01 to 1.73 | 0.044 |
| Acute MI | 1.35 | 1.06 to 1.71 | 0.015 |
| Second‐generation stent | 0.69 | 0.57 to 0.85 | <0.001 |
| CKD group | |||
| Complete revascularization | 1.39 | 1.06 to 1.82 | 0.018 |
| Male | 1.41 | 1.08 to 1.84 | 0.013 |
| Hypertension | 1.48 | 1.08 to 2.03 | 0.014 |
| Acute MI | 2.80 | 2.09 to 3.76 | <0.001 |
| PCI to CTO lesion | 1.46 | 1.04 to 2.06 | 0.031 |
| Second‐generation stent | 0.68 | 0.51 to 0.92 | 0.011 |
The C‐index of the models were 0.618 (95% CI, 0.605%–0.631%) and 0.655 (95% CI, 0.638%–0.672%) for non‐CKD and CKD population, respectively. CI indicates confidence interval; CKD, chronic kidney disease; CTO, chronic total occlusion; CVA, cerebrovascular accident; HR, hazard ratio; IPTW, inverse probability of treatment weighting; MI, myocardial infarction; PCI, percutaneous coronary intervention; POCO, patient‐oriented composite outcomes; SYNTAX, Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery.
Adjusted HR was calculated using IPTW adjusted multivariate Cox regression analyses. The included covariables were complete revascularization, age, sex, hypertension, diabetes mellitus, smoking, previous CVA, previous peripheral vascular disease, dyslipidemia, previous MI, previous PCI, clinical diagnosis, type of inserted stent, SYNTAX score, PCI for left main coronary artery, bifurcation, ostial, CTO, and type B2/C lesion.
