作者(1976.6～1980.9)对平均年龄52(25～69)岁的131(男115、女16)例在内科治疗下无症状或者仅有轻微(稳定型)心绞痛的冠心病患者进行试验,并继续观察平均44个月。凡有冠(状动)脉旁路手术史、近期(≤6个月)心肌梗塞史、静息心绞痛或左主干狭窄者已除外。冠脉造影示单支、双支和三支(内径)狭窄(≥50％)者分别有41例、42例和48例。停用心脏活性药物后,作放射性核素造影测定静息时左室射血分数(LVEF)和左室壁节段活动异常(WMA),并于症状限制性卧位蹬车试验结束前2分钟
The authors (1976.6 ~ 1980.9) tested 131 patients (115 men and 16 women) with mean age 52 (25-69) years with coronary heart disease asymptomatic or mild (stable) angina under medical treatment and continued Observed an average of 44 months. Where coronary artery bypass surgery history, recent (≤ 6 months) history of myocardial infarction, resting angina or left main stenosis who have been excluded. Coronary angiography showed 41 cases, 42 cases and 48 cases with single branch, double branch and three branches (internal diameter) stenosis (≥50%) respectively. After discontinuation of cardiorespiratory drugs, left ventricular ejection fraction (LVEF) and left ventricular wall motion abnormalities (WMA) at rest were measured by radionuclide imaging and 2 minutes before the end of the symptom-limited pedaling test
