摘　　要：目的：探讨原有的左心室肥厚对急性心肌梗死后左室重构的影响和作用。方法：对２６例前壁心肌梗死患者在入院后ｄ１、ｄ７、１个月和３个月时进行二维超声心动图检查，测量左室舒张末容积指数（ＬＶＥＤＶＩ）、收缩末期容积指数（ＬＶＥＳＶＩ）、射血分数（ＥＦ）、室间隔厚度（ＩＶＳ）、左室壁厚度（ＰＷ）。结果：无左室肥厚的９例患者在心梗后第一周发生了左室扩张，表现为ＬＶＥＤＶＩ、ＬＶＥＳＶＩ明显增加，无明显的左室扩张（Ｐ＜０．０５）。结论：原有左室肥厚对梗死后左室重构的发生发展产生重要的影响。Objective:In order to study the effect of left ventricular hypertrophy(LVH) on left ventricular remodelling after acute myocardial infarction(AMI).Methods:26 patients with anterior wall AMI were prospectively examined by serial echocardiography in the following seqnence: the first, seventh day, one and three months after being admitted in hospital. left ventricular enddiastolic volume index (LVEDVI), left ventricular endsystolic volume index (LVESVI), ejection fraction (EF), basal interventricular septum(ivs) and posterior wall thickness (PW) were measurd. According to their baseline LV thidckness patients were divided into group I (LVH) and groupⅡ (NLVH)(IVS+pw)=24±1 mm and 20±2 mm respectively). Results:Our study showed that at the end of 3 months, LVEDVI, LVESVI increased in GroupⅡ and didnt in Group Ⅰ (P<0.05) (LVEF). Conclusion:This suggested that baseline LVH is an important factor governing infarct expansion and LV after AMI remodeling.
