Quantitative coronary angiography
| Group A (n = 80) | group B (n = 266) | p Value | |
|---|---|---|---|
| Data are mean (SD). Acute gain is defined as the difference in minimum lumen diameter before and after the intervention. Late loss is defined as the difference in minimum lumen diameter immediately after the intervention and at follow up. | |||
