| 摘 要： | 目的:比较急性Q波性心肌梗死(QMI)和非Q波性心肌梗死(NQMI)患者临床和冠状动脉病变特征以及梗死相关区域存活心肌的情况,并随访观察其对心肌梗死晚期血运重建术后心功能的影响。方法:连续收集121例急性心肌梗死(AMI)患者,分为QMI组(79例)和NQMI组(42例)。详细记录和分析所有患者的病史资料。于AMI后2周左右行经皮冠状动脉介入治疗,术前采用小剂量多巴酚丁胺超声负荷试验,检查梗死相关区域存活心肌的情况,并且于术前和术后6个月时常规超声心动图检查左室功能和室壁节段性运动障碍情况。随访6个月内主要心血管事件的发生率。结果:AMI前有心绞痛发作史者和冠状动脉病变血管的数量在NQMI组明显多于QMI组(P<0.05),而梗死相关部位平均管腔残余狭窄以NQMI组明显小于QMI组(P<0.05)。NQMI组中86%的患者有存活心肌,明显高于QMI组(61%)(P<0.01)。术后6个月随访,2组左室射血分数较术前明显提高,左室舒张末期及收缩末期容积指数、室壁运动积分均较术前明显降低(分别为P<0.05和P<0.01),以NQMI组更明显。结论:与QMI相比,NQMI患者有较多的存活心肌;心肌梗死后晚期血运重... |

| Abstract: | Objective:To compare the clinical and angiographic distinctions as well as viable myocardium between Q wave and non-Q wave myocardial infarction,and its effect on left ventricular systolic function after late revascularization. Method:A total of 121 consecutive patients with acute myocardial infarction (AMI) were selected,and divided into the QMI group (n=79) and the NQMI group (n=42). The data of clinical manifestation and angiogram were analyzed. All patients received successful percutanous coronary angio... |
