【摘要】：目的研究左心室肌小梁增多伴发的心内结构及功能改变,初步探讨其发生的可能因素。方法筛选经胸超声心动图检查的左心室肌小梁增多成人患者,纳入其中在收缩末期胸骨旁左心室短轴切面观测量左心室非致密层心肌/致密层心肌(NC/C)2者120例。测量左心室舒张末期前后径(LVEDD)和左心室射血分数(LVEF),二维结合彩色多普勒(CDFI)观察肌小梁间有无深陷隐窝。结合临床资料及其他检查对病因进行分类。结果左心室肌小梁增多见于扩张型心肌病改变52例、心肌梗死13例、心瓣膜病28例、先天性心脏病12例以及无明确病因15例。其中,无明确病因组LVEDD、LVEF值与其他病因组比较,差异有统计学意义(P0.01)。有14例可见深陷隐窝,分别见于扩张型心肌病改变5例、先天性心脏病1例、无明确病因8例。左室肌小梁增多合并隐窝(14例)与单纯肌小梁增多(106例)比较,LVEDD(54.5±8.2vs 64.8±10.3)mm、LVEF(50.2±9.1vs 41.6±8.7)%,差异均有统计学意义(P0.01)。结论左心室肌小梁增多见于多种病因,不仅仅是左心室心肌致密化不全的特征性改变,亦可能是慢性心力衰竭进展过程中左心室重构的一种继发性改变。
[Abstract]:Objective to study the changes of cardiac structure and function in patients with left ventricular trabeculae (LVMC) and to explore the possible factors of its occurrence. Methods Transthoracic echocardiography was performed in adult patients with increased left ventricular trabeculae. One hundred and twenty cases were included in this study. The left ventricular noncompact layer myocardium / compact layer myocardium were measured on the short axis section of the left ventricular near the sternum and the left ventricular end diastolic diameter was measured by LVEDDD. And left ventricular ejection fraction (LVEF). Two dimensional color Doppler imaging (CDFI). The causes were classified by clinical data and other examinations. Results 52 cases of dilated cardiomyopathy were found in the increase of left ventricular trabeculae. There were 13 cases of myocardial infarction, 28 cases of cardiac valvular disease, 12 cases of congenital heart disease and 15 cases of no definite etiology. There were 14 cases with deep recess, 5 cases with dilated cardiomyopathy and 1 case with congenital heart disease. There were no definite etiology in 8 cases. 14 cases of left ventricular trabeculae with recess) were compared with 106 cases of simple muscle trabeculae. LVEDD(54.5 卤8.2 vs 64.8 卤10.3mm LVEDD(54.5 50.2 卤9.1 vs 41.6 卤8.7%. Conclusion the increase of left ventricular trabeculae is seen in many causes, not only the characteristic changes of left ventricular myocardial compaction insufficiency. It may also be a secondary change in left ventricular remodeling during the progression of chronic heart failure.
