急性心肌梗死后早期左室形态变化的研究

Shape changes of left ventricle after acute myocardial infarction in early stage

目的 :探讨急性心肌梗死 (AMI)发病后 1～ 3周内左室形态、构型的动态变化。方法 :应用二维超声心动图 (2 - DE)对 32例 AMI患者分别于发病后第 1周、第 2周和第 3周连续测量并计算左室形态、构型的各项指标 ,对其结果进行对比分析 ,并与 33例正常人进行对照。结果 :32例 AMI患者中 ,14例 (44 % )发生左室重构(L VR) ,有明显的左室形态及构型变化 ,从 1周到 3周 AMI患者左室形态的变化呈进行性加重 ,以第 3周最为显著 ,且重构组的改变较非重构组为明显。结论 :AMI后左室形态、构型的改变与 AMI后早期 L

To discuss the shape,geometry changes of left ventricle (LV) within three weeks after acute myocardial infarction (AMI).Method:The indexes of LV shape,geometry were measured in 32 patients with AMI at 1 week,2 weeks and 3 weeks after the attack using two dimensional echocardiography (2 DE),and compared with 33 normal control cases.Result:Of all the 33 patients with AMI,14(44%) showed obvious shape and geometric changes in LV. The changes of LV were progressively worse from 1 week to 3 weeks after attack with the peak in 3 weeks,and the changes in remodeling group (n=14) were significant than that of non remodeling group (n=18).Conclusion:The LV changes were closely associated with early LV remodeling occurred after AMI.
