Table 3. Clinical outcomes through to 1 year in the entire population, training population and validation population.
| Lesion-level outcomes | All lesions (N=2,392) | Training (N=1,778) | Validation (N=614) | Hazard ratio (95% CI) |
|---|---|---|---|---|
| Repeat PCI for recurrent DES-ISR | 402 (17.7) | 299 (17.7) | 103 (17.7) | 1.01 (0.79-1.25) |
| Definite stent thrombosis | 3 (0.1) | 2 (0.1) | 1 (0.2) | 1.47 (0.00-9734.2) |
| Patient-level outcomes | All patients (N=1,986) | Training (N=1,471) | Validation (N=515) | Hazard ratio (95% CI) |
| All-cause mortality | 90 (4.7) | 63 (4.5) | 27 (5.5) | 1.23 (0.79-1.93) |
| Myocardial infarction | 31 (1.6) | 24 (1.7) | 7 (1.4) | 0.83 (0.36-1.94) |
| Coronary artery bypass grafting | 18 (1.0) | 15 (1.1) | 3 (0.6) | 0.57 (0.17-1.98) |
| Data are number of events with Kaplan-Meier estimates for all-cause mortality (%) or cumulative incidence (%) after accounting for competing risk of death for all other events. The hazard ratio and 95% confidence interval (95% CI) reported is for the comparison between the training and validation populations. DES: drug-eluting stent; ISR: in-stent restenosis; PCI: percutaneous coronary intervention | ||||
