Comparison of the parameter in three major coronary artery subgroups.
| Subgroup | Non-ISR/ISR | Peri-stent FAI (HU) | P -value |
|---|---|---|---|
| LAD stent | Non-ISR (n = 40) | −86.1 ± 6.0 | <0.001*** |
| ISR (n = 33) | −79.5 ± 5.8 | ||
| LCx stent | Non-ISR (n = 9) | −85.9 ± 6.0 | 0.003** |
| ISR (n = 11) | −75.7 ± 7.0 | ||
| RCA stent | Non-ISR (n = 16) | −90.9 ± 9.9 | <0.001*** |
| ISR (n = 8) | −75.2 ± 5.4 |
Values are given as mean ± SD (range) or n (%), “**”, “***” indicate significance at p < 0.01 and p < 0.001 respectively.
ISR, in-stent restenosis; FAI, fat attenuation index; LAD, left anterior descending coronary artery; LCx, left circumflex coronary artery; RCA, right coronary artery.
