Table 4. Results of logistic regression analysis for repeat PCI for recurrent DES-ISR from 0 to 1 year after after the first reintervention for DES-ISR.
| Variable | Regression coefficient | p-value |
|---|---|---|
| Non-focal ISR at index PCI | 0.346 | 0.029 |
| Age | −0.007 | 0.297 |
| Hypercholesterolaemia | 0.161 | 0.310 |
| Smoking | 0.197 | 0.328 |
| Acute coronary syndrome | 0.054 | 0.736 |
| Multivessel disease | 0.259 | 0.401 |
| Left circumflex coronary artery | 0.288 | 0.048 |
| Vessel calcification | 0.359 | 0.020 |
| Ostial lesion | 0.378 | 0.169 |
| Bifurcation lesion | 0.143 | 0.333 |
| ISR severity >90% | 0.178 | 0.383 |
| Device diameter | −0.174 | 0.220 |
| Restenosis interval <6 months | 0.506 | 0.008 |
| Significant correlates are in bold. DES: drug-eluting stent; ISR: in-stent restenosis; PCI: percutaneous coronary intervention | ||
