直接经皮冠状动脉介入治疗(primary percutaneous coro-nary intervention,PCI)是在急性心肌梗死(acute myocardial。infarction,AMI)病人不进行静脉溶栓而直接冠脉造影时,即刻开通梗塞相关血管(infarct-related artery,IRA)的一种治疗方法,其目标是减少坏死心肌范围,挽救存活心肌。与溶栓相比,直接 PCI 具有的优势是:1.较溶栓治疗的适应症广泛;2.可即刻了解冠脉解剖和左室功能;3.可了解冠脉病变特征,进行危险分层;4.快速开通梗塞相关动脉,恢复冠脉前向血流;5.再次心肌梗死、再次发生严重的心肌缺血和急性闭塞的发生率低;6.急、高危和重症的急性心肌梗死的存活率高,住院时间短,内脏出血较少。一临床资料本研究资料为我院2000年6月～2006年12月收住的
Direct percutaneous coronary intervention (PCI) is the immediate initiation of infarct-related blood vessels in patients undergoing acute myocardial infarction (AMI) without intravenous thrombolysis -related artery (IRA), a treatment that aims to reduce the area of necrotic myocardium and save the viable myocardium. Compared with thrombolysis, direct PCI has the following advantages: 1. Thrombolytic treatment of a wide range of indications; 2. Immediate understanding of coronary artery anatomy and left ventricular function; 3. Can understand the characteristics of coronary lesions, risk stratification ; 4. Rapid opening of infarct-related arteries and restoration of anterior coronary blood flow; 5. Recurrent myocardial infarction with a recurrence of severe myocardial ischemia and a low incidence of acute occlusion; 6. Acute, high-risk and severe acute myocardial infarction High survival rate, shorter hospital stay, less visceral bleeding. A clinical data of this study for our hospital in June 2000 ~ December 2006 admitted
