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 VR密切相关
Objective: To investigate the dynamic changes of left ventricular morphology and configuration within 1 to 3 weeks after onset of acute myocardial infarction (AMI). Methods: Two - dimensional echocardiography (2 - DE) was used to measure and calculate the left ventricular morphology and conformation in 32 patients with AMI at the first week, the second week and the third week respectively. Results were compared and analyzed with 33 normal subjects. Results: Among the 32 patients with AMI, left ventricular remodeling (LVR) occurred in 14 patients (44%) with obvious left ventricular morphology and conformational changes. The changes of LV morphology in AMI patients from 1 week to 3 weeks were progressive Aggravating, the third week is the most significant, and the remodeling group changes than non-remodeling group was obvious. Conclusion: The change of left ventricular morphology and configuration after AMI is closely related to the early post-AMI L VR
