32例冠状动脉粥样硬化性心脏病(冠心病)患者,平均年龄(58±12)岁,病损冠状动脉狭窄度(82±6)%。均于冠状动脉支架术前和术后30分钟～2小时,经UCG分别检测心室射血分数(ejectionfraction,EF)和心室肌收缩期增厚幅度(systolicthickening,百分比Th)。然后随机分为静脉注射α1受体
In 32 patients with coronary atherosclerotic heart disease (CHD), the mean age was (58 ± 12) years and the severity of coronary artery stenosis was 82 ± 6%. Before coronary artery stenting and 30 minutes to 2 hours after surgery, ventricular ejection fraction (EF) and systolic thickening (percentage Th) were measured by UCG. Then randomly divided into intravenous α1 receptor
