OFDI analysis of the underlying plaque.
| OFDI characteristics of the plaque | Diseased LM (n = 32) |
| Fibrous plaque | 22 (68.7%) | Fibrocalcific plaque | 10 (31.3%) | Cholesterol crystals | 5 (15.6%) | Thrombus | 4 (12.5%) | Microchannels | 5 (15.6%) | Disappearance of media | 22 (68.7%) |
| OFDI quantitative analysis | Normal LM (n = 10) | Diseased LM (n = 32) |
| Intima thickness (mm) | 0.10 ± 0.02 | 0.53 ± 0.22 | Media thickness (mm) | 0.10 ± 0.02 | 0.14 ± 0.10 | Intima/media ratio | 1.0 ± 0.17 | 4.70 ± 2.51 |

CABG = coronary artery bypass graft; eGFR = estimated glomerular filtration rate; LA = lumen area; LAD = left anterior descending artery; LCX = left circumflex artery; LM = left main; OFDI = optical frequency domain imaging. diseased vs normal LM. |
