| 2 vessels | 169 (55.0) | 303 (68.3) | 322 (76.4) | 217 (85.7) | 1011 (72.4) |
| 3 vessels | 130 (22.3) | 204 (19.6) | 177 (35.6) | 119 (49.6) | 630 (30.3) |
| 2 or 3 vessels | 299 (40.8) | 507 (48.7) | 499 (61.9) | 336 (72.9) | 1641 (56.2) |
| Left main artery | 80 (11.3) | 103 (5.8) | 104 (19.2) | 81 (14.8) | 368 (12.8) |
| Prior CABG | 43 (97.7) | 95 (91.6) | 118 (89.8) | 63 (96.8) | 319 (92.8) |
Note: CABG = coronary artery bypass graft, PCI = percutaneous coronary intervention.
