扩张性心肌病形成左心室血栓的相关因素分析

目的:通过超声心动图观察,探讨扩张性心肌病左心室血栓形成的相关因素。方法:根据超声心动图检查有、无左心室血栓,83例扩张性心肌病患者被分为A组(左室血栓组)和B组(左室无血栓组)。结果:左房内径、左室收缩期末内径、EF值、二尖瓣中等返流及主动脉瓣返流量在两组之间有显著差异(P<0.05~<0.01),而左室舒张末内径、室壁厚度及年龄、性别则无差异。结论:左室收缩功能的降低,左房内径的增大对左室血栓的形成有重要促进作用。而二尖瓣及主动脉瓣的中等量返流对左室血栓的形成有一定的对抗作用。

Analysis about some relational factor on formation of left ventricular thrombus in dilated cardiomyopathy

ve: To explore some relational factor on formation of left ventricular thrombus in dilated cardiomyopathy based on echocardiography observations. Methods: Eight-three patients with dilated cardiomyopathy were divided into A group (there is the ventricular thrombus) and B group (there is not the left ventricular thrombus) by the chest echocardiography examination. Results:There were statistical significance between two group in left artrial internal diameter (LA), left ventricular systolic internal diameter (LVDs), EF, the moderate quantity of the mitral and aortic regurgitation (P<0. 05~<0. 01). Conclusion: Some factor advance to formation of left ventricular thrombus such as the decrease of left ventricular systolic function, enlargement of left ventricular systolic internal diameter and left atrial internal diameter; contrary, some factor example the moderate regurgitation of mitral and aortic valve restrain its formation.
