1983年1月至1985年8月间,连续281例心绞痛患者接受经皮冠(状动)脉腔内成形术(PTCA)并获得成功(残留内径狭窄<50％),包括189例单支冠脉病变(内径狭窄>70％)患者和92例(单一明显心肌缺血区的)多支冠脉病变(1支内径狭窄>70％,另支内径狭窄>50％)患者。单支病变患者PTCA成功后,均视为完全再血管化。多支病变患者PTCA成功后:19例无一支残留内径狭窄≥50％,视为完全再血管化;73例未扩张成形的一支残留内径狭窄》50％,视为不完全再血管化。PTCA后,随访12±4(6～18)个月。多支病变组同单支病变组相比:临床改善者较少(81％对95％,p=0.001),心绞痛消失者较少
Between January 1983 and August 1985, 281 consecutive patients with angina underwent percutaneous transluminal coronary angioplasty (PTCA) with success (residual stenosis <50%), including 189 single coronary crowns Patients with arterial lesions (> 70% IDS) and 92 patients with multiple coronary lesions (> 70% ID diameter> 50% ID <50%) with a single myocardial infarction were identified. Patients with single-vessel disease after successful PTCA, are considered completely revascularization. After PTCA was successful in multi-vessel disease: none of the 19 patients had ≥50% residual stenosis, which was considered complete revascularization; and 73 patients with a residual stenosis of 50%, which were not expanded, were considered as incomplete revascularization. After PTCA, follow-up 12 ± 4 (6 ~ 18) months. In the multi-vessel disease group, compared with the single vessel disease group, there were fewer clinical improvements (81% vs 95%, p = 0.001) and fewer disappearances of angina pectoris
