Angiographic characteristics of the analyzed 274 coronary arterial segments.
| Control | DCB-Treated | Spastic | * p Value | |
|---|---|---|---|---|
| Reference vessel diameter, after nitrate (mm) | 3.12 ± 0.60 † | 2.72 ± 0.41 | 2.70 ± 0.48 | 0.718 |
| Diameter stenosis, after nitrate (%) | 12.72 ± 0.68 † | 24.21 ± 0.82 | 17.57 ± 1.00 | <0.001 |
| Minimal lumen diameter, baseline (mm) | 2.54 ± 0.57 † | 1.90 ± 0.42 | 1.94 ± 0.46 | 0.438 |
| Minimal lumen diameter, after ergonovine (mm) | 2.20 ± 0.57 † | 1.58 ± 0.41 | 1.37 ± 0.44 | <0.001 |
| Minimal lumen diameter, after nitrate (mm) | 2.73 ± 0.61 † | 2.06 ± 0.40 | 2.22 ± 0.47 | 0.003 |
Values are means ± standard deviation. * p value denotes the difference between DCB-treated vs. spastic segments. † Significantly different compared to both DCB-treated and spastic segments (p < 0.001). DCB: drug-coated balloon.
