目的分析心尖肥厚型心肌病(AHCM)患者的超声心动图声像,探讨超声心动图诊断AHCM的价值。方法 AHCM组20例和健康对照组20例分别进行超声心动图检查,分析比较心尖部心肌厚度,左房径、左室径和左室射血分数等参数。结果与对照组相比,AHCM患者心尖部心肌显著增厚,左房径增大(P﹤0.05),左室径与射血分数与对照组相比差异无统计学意义。结论超声心动图是诊断AHCM准确、易行的无创方式。
Objective To analyze echocardiographic echocardiography in patients with apical hypertrophic cardiomyopathy (AHCM) and evaluate the value of echocardiography in the diagnosis of AHCM. Methods Echocardiography was performed in 20 cases of AHCM group and 20 cases of healthy control group. The parameters of atrial myocardial thickness, left atrium diameter, left ventricular diameter and left ventricular ejection fraction were analyzed. Results Compared with the control group, the apical myocardium in AHCM patients was significantly thicker and the left atrium diameter was increased (P <0.05). The left ventricular diameter and ejection fraction were not significantly different from those in the control group. Conclusion Echocardiography is an accurate and feasible noninvasive method to diagnose AHCM.
