Comparison of perioperative lesion data between CABG and PCI groups after propensity score matching
| Procedural variables | CABG group (n = 406) | PCI group (n = 406) | Statistical values | P |
|---|---|---|---|---|
| Left main stenosis | 50 (12.3) | 51 (12.6) | 0.0130 | 0.9093 |
| Number of narrowed coronary arteries | 3.0 ± 0.7 | 3.0 ± 1.1 | 0.1780* | 0.8588 |
| 1 | 9 (2.2) | 43 (10.6) | <0.0001 | |

| ≥4 | 11 (24.9) | 140 (34.5) | ||
| Artery intervention | ||||
| LAD | 397 (97.8) | 349 (86.0) | 36.0000 | <0.0001 |
| Diagonal | 185 (45.6) | 123 (30.3) | 22.3488 | <0.0001 |

The data are shown as mean ± SD or n (%). *Compared by paired t-test; otherwise by McNemar’s test or Fisher’s exact test. CABG: Coronary artery bypass grafting; PCI: Percutaneous coronary intervention; LAD: Left anterior descending artery; LCX: Left circumflex; PDA: Posterior descending artery; PLA: Posterior left ventricle artery; RCA: Right coronary artery; SD: Standard deviation.
