|
Diabetic recipients (n=19) | |
| One year post-transplant (25%) | RCA: mild irregularity |
| RCA: >80% stenosis; LAD: mild irregularity distally | |
| LAD: 50% stenosis distally | |
| Three years post-transplant (42%) | Diagonal artery: mild irregularity |
| RCA: mild irregularity | |
| LAD: mid/distal ectasia; CX: proximal ectasia | |
| RCA, LAD, CX: mild irregularities | |
| RCA: mild irregularity, and diffuse, severe narrowing and occlusion in the PD and PL; LAD: diffuse, severe narrowing distally with small branch occlusion; CX: occluded distally; obtuse marginal artey: ectasia proximally with midsegment 40% to 50% stenosis | |
|
Nondiabetic recipients (n=117) | |
| One year post-transplant (11%) | PL, RI: ectasia distally |

| LAD: 30% stenosis | |
| LAD: occluded distally with diffusely narrowed, occluded septal branches; CX: diffusely narrowed; Diagonal artery: diffusely diseased; RI: occluded proximally; Marginal artery: 80% to 90% stenosis | |
| RCA: diffuse, severe narrowing in branches; LAD: diffuse, severe narrowing distally; CX, diagonal artery: diffuse narrowing | |
| LAD: 30% ostial stenosis, diffuse mild irregularity | |
| RCA: 30% stenosis | |
| LAD, CX: diffuse, severe narrowing; PD: irregularity | |
| Three years post-transplant (13%) | RCA: diffuse irregularity, ectasia; LAD, CX: diffuse irregularity, multiple areas of ectasia |

Percentages in parentheses represent the percentage of abnormal angiograms. Results are organized as the individual results of abnormal angiograms in each category. CX Circumflex artery; LAD Left anterior descending artery; PD Posterior descending artery; PL Posterolateral artery; RCA Right coronary artery; RI Ramus intermedius
