摘　　要：目的探讨彩色多普勒(CDFI)与其他检查方法对心尖肥厚型心肌病(AHCM)的诊断价值。方法对31例AHCM患者的CDFI、磁共振检查(MRI、冠脉造影及左心室造影(CAG+LVG)、心电图(ECG)特点进行分析。结果31例均经CDFI检查,28例证实有心尖部心肌肥厚(厚度>15 mm),心尖最大室壁厚度/基底部最大室壁厚度≥1.3。9例进行了LVG,其中有4例显示左室舒张期末心尖部心肌肥厚,左心室舒张末期呈"黑桃"(spade-like)样改变。4例行了MRI检查,均可见心尖部不对称性肥厚。全部患者均合并有ECG异常改变(100%)。31例中有1例合并有右室心尖肥厚。结论CDFI为AHCM最理想的检测方法,如结合以上其他检查,则可进一步提高诊断准确性。Objective To evaluate the value of color doppler flow imaging （CDFI） in the diagnosis of apical hypertrophy cardiomyopathy （AHCM） and compare it with other diagnostic methods. Methods The CDFI and electrocardiogram （ECG） characteristics, MRI, coronary angiography and left ventricular angiography （ CAG ＋ LVG） results of 31 AHCM were retrospectively reviewed. Results In all 31 patients, CDFI showed left ventricular apex hypertrophy（ free wall of left ventricle and/or inter ventricular septum below the level of papillary muscle） in 28 cases （ the thickness ≥15 mm）, 9 cases carried on the left ventricle angiogrephy, including 4 cases in ventricle angiography have the apical ＂spade-like＂ changes.4 cases carried on MRI,all cases showed left ventricular apex hypertrophy. All the cases have abnormal ECG characteristics （ 100% ） ,1 ease complicated with apical hypertrophy of right ventricle. Conclusion CDFI is valuable in the diagnosis of AHCM. Combined with other diagnostic methods,the diagnostic sensitivity of AHCM could be improved.
