肥厚性心肌病伴左室流出道梗阻可见于冠心病,然而其发病率不详,且是否为冠心病的继发病变抑或同时存在原发性心肌病亦仍不明确。本文旨在探讨非对称性室间隔增厚在冠心病患者中的发生率,以及这类病人中的非对称性室间隔增厚是否属于遗传性肥厚性心肌病。方法和结果:79例因胸痛或冠心病而入院的患者,其中74例造影显示冠状动脉管腔狭窄≥75％,5例为50～75％。79例中7例超声心动图检查显示室隔/游离后壁比值>1.3,符合非对称性室间隔增厚的诊断标
Hypertrophic cardiomyopathy with left ventricular outflow tract obstruction can be seen in coronary heart disease, but its incidence is unknown, and whether the secondary lesion of coronary heart disease or concurrent primary cardiomyopathy is still not clear. This article aims to investigate the incidence of asymmetric ventricular septal thickening in patients with coronary heart disease and whether asymmetric ventricular septal thickening in such patients is inherited hypertrophic cardiomyopathy. Methods and Results: Seventy-nine patients admitted to hospital for chest pain or coronary heart disease showed angiography of 74 cases with coronary stenosis ≥75% and five cases 50-75%. In 79 cases, echocardiography was performed in 7 cases and the ratio of ventricular septum / posterior wall was> 1.3, which was in line with the diagnostic criteria for asymmetric ventricular septal thickening
