Angiographic Characteristics and Method of Reperfusion
| Infarct-related vessel LAD/LCx/RCA | 48 (59%)/11 (14%)/22 (25%) |
| Diameter stenosis before intervention | 99 ± 3% |
| Diameter stenosis after intervention | 33 ± 18% |
| TIMI flow grade before intervention | |
| 0–1/2/3 | 59 (73%)/15 (19%)/7 (9%) |
| TIMI flow grade after intervention | |
| 2/3 | 2 (2%)/79 (98%) |
| Left ventricular ejection fraction* | 52 ± 15% |
| Method of reperfusion therapy | |
| Primary PTCA | 57 (70%) |
| Rescue PTCA | 14 (17%) |
| Delayed PTCA | 4 (5%) |
| Thrombolysis alone | 6 (7%) |
LAD = left anterior descending coronary artery; LC, = left circumflex coronary artery; PTCA = percutaneous transluminal coronary angioplasty; RCA = right coronary artery; TIMI = Thrombolysis in Myocardial Infarction trial.
↵* Left ventricular ejection fraction was measured by left ventriculography at one-month follow-up. Data are presented as the number (%) of patients or mean value = SD.
