Diagnostic Value of Two Dimensional and Color Doppler Echocardiography in Apical Hypertrophic Cardiomyopathy

目的 探讨二维彩色多普勒超声检查对心尖肥厚型心肌病 (AHCM )的临床价值。方法 应用二维彩色多普勒超声检查并诊断 3 0 1例肥厚型心肌病病人。结果 心尖肥厚型心肌病 5 8例 ,占 19.2 7% ;男多于女 ( 4∶1) ;年龄集中在中老年 ;多表现为室间隔心尖段和乳头肌水平以下左室游离壁肥厚 ,仅有 5例表现乳头肌水平以下右室游离壁肥厚 ;左房扩大 3 8例 ;二尖瓣返流 3 3例 ,主动脉瓣返流 2 1例 ,大部分为轻度返流 ;左室收缩功能正常 ,3 8例表现左室舒张功能减退。结论 二维彩色多普勒超声检查是诊断AHCM简便。

Objective To evaluate the clinical value of two dimensional and color Doppler echocardiography in the patients with apical hypertrophic cardiomyopathy (AHCM). Methods 301 cases of patients with hypertrophic cardiomyography (HCM) were examined by two dimensional and color Doppler echocardiography. Results 58 cases out of 301 HCM patients with AHCM were diagnosed. The detection rate was 19.27%. The male patients of AHCM were 4 times more than female (4:1). Most patients were middle-aged and old-aged people. Most of patients showed thickening of interventricular septum and left ventricular free wall under the papillary level. There were 38 cases with a enlarged left atrium, 33 cases with mitral regurgitation, 21 cases with aortic regurgitation and 38 cases with left ventricular diastolic dysfunction. All patients had a normal left ventricular systolic function. Conclusion The examination of two dimensional and color Doppler echocardiography was a simple and accurate diagnostic method of AHCM.
