高血压性心肌病与缺血性心肌病超声表现对比分析

Comparative analysis of hypertensive cardiomyopathy and ischemic cardiomyopathy by echocardiography

目的 :探索高血压性心肌病 (HC)与缺血性心肌病 (ICM)的超声鉴别方法。方法 :对比分析 30例 HC及2 0例 ICM超声资料。结果 :HC按不同分类表现为 :左室向心性肥厚的左室重量指数、左室相对壁厚均增加 ,并且左房扩张。左室离心性扩张型的左室重量指数增加。所有 HC患者均有不同程度的主动脉瓣或主动脉根部钙化。ICM左室大多数呈“圆拱门形”,心尖圆钝变薄 ,收缩期运动明显低平 ,节段性室壁运动障碍及主动脉增宽。结论 :超声心动图是鉴别 HC与 ICM患者的一种有价值的无创性检查手段。

Objective:To investigate the differential diagnosis of hypertensive cardiomyopathy(HC) and ischemic cardiomyopathy(ICM) by echocardiography.Method:Comparetive analysing the echocardiographic findings of 30 patients with HC and 20 patients with ICM.Result:HC might show left ventriculan (LV) centripetal or eccentric hypertrophy.In LV centripetal hypertraphy,the LV mass index (LVMI) and the relative LV wall thickness(RWT) were increased.The left atrium was also enlarged. In eccentric type of IV enlargement,the LVMI was increased. In all of HC,there were certain degree of aortic valve on aortic root calcification. In most of patient with ICM,the LV typically showed “spherical apex”,regional wall hypokinesis and dilated aorta.Conclusion:The results suggest that echocardiography is a valuable noninvasive technology in the differential diagnosis of HC and ICM.
