如何预防冠心病介入治疗后冠状动脉的再狭窄是当今的研究热点,本研究目的为评定卡维洛尔(Carvedilol)预防冠状动脉粥样斑块旋切术(DCA)后冠脉再狭窄效果。对象与方法研究对象为稳定性及不稳定性心绞痛符合DCA手术指征者。以下情况排除:有应用卡维洛尔反指征,即心动过缓心率低于50bpm、Ⅱ～Ⅲ度房室传导阻滞、阻塞性肺部疾病、胰岛素依赖性糖尿病者,以及未能坚持β受体阻滞剂
How to prevent restenosis of coronary artery after interventional treatment of coronary heart disease is a hot research topic nowadays. The purpose of this study is to evaluate the effect of Carvedilol on prevention of coronary restenosis after coronary atherosclerotic plaque biopsy (DCA). Subjects and methods of study for the stability and instability of angina pectoris consistent with indications for DCA surgery. The following conditions were excluded: the use of anti-cardivolol indications, ie bradycardia heart rate below 50bpm, Ⅱ ~ Ⅲ degree atrioventricular block, obstructive pulmonary disease, insulin-dependent diabetes, and failed to adhere to β Receptor blockers
