作者(1983.1～1985.6)为平均年龄57(36～74)岁的71(男58、女13)例不稳定型心绞痛(UAP)患者于确诊(静息心绞痛>≥15min伴ST-T波改变,但无心肌坏死的酶学和心电图依据)后随即择期施行经皮冠(状动)脉腔内血管成形术(PTCA)。这类患者急性期经药物治疗后病情已趋稳定但是仍有持续性劳力型心绞痛,造影示与UAP有关的冠脉病变适宜于PTCA以及冠脉旁路移植(CABG)治疗。本组中:
The authors (1983.1 ~ 1985.6) included 71 patients (58 male and 13 female) with unstable angina (UAP) who had a mean age of 57 (36-74 years) who had been diagnosed with ST-T wave changes of resting angina> 15 min, But no evidence of myocardial necrosis based on enzymology and electrocardiogram) followed by percutaneous transluminal coronary angioplasty (PTCA). Patients with acute phase after drug treatment have stabilized but still have persistent angina pectoris, angiography showed UAP-related coronary lesions suitable for PTCA and coronary artery bypass graft (CABG) treatment. In this group:
