摘　　要：目的探讨肥厚型心肌病(HCM)伴左心室心尖部室壁瘤(LVAA)的MRI对比延迟强化特征及其预后。方法选取2009年1月至2019年2月本院收治的HCM伴LVAA患者45例,均接受心脏MRI检查。结果其中30例有瘤壁MRI对比延迟强化(强化组),15例无瘤壁MRI对比延迟强化(无强化组)。强化组患者左心室质量为(105.54±45.54)g/m^(2),明显高于无强化组患者(P<0.05);两组患者性别、年龄、左心室舒张末期内径、左心室最大室壁厚度等比较差异无统计学意义(P>0.05);强化组患者发生不良心血管事件的时间为86.50个月,明显快于无强化患者的110.31个月(P<0.05);强化组患者不良心血管事件发生率为50.00%,明显高于无强化患者(P<0.05)。结论HCM伴LVAA患者MRI对比延迟强化有一定临床价值,对判断患者预后有一定帮助。Objective To investigate the delayed enhancement MR characteristics and prognosis of hypertrophic cardiomyopathy(HCM)with left ventricular apical aneurysm(LVAA).Methods Forty five patients with HCM and LVAA who were treated in our hospital from January 2009 to February 2019 were selected for cardiac MR examination.Results There were 30 patients with delayed enhancement of tumor wall MR contrast,15 patients without delayed enhancement of tumor wall MR contrast.The left ventricular mass of patients with tumor wall MR contrast delayed enhancement was(105.54±45.54)g/m^(2),which was significantly higher than that of patients without tumor wall MR contrast delayed enhancement(P<0.05).There were no significant difference in gender,age,end diastolic diameter of left ventricle,and the maximum wall thickness of left ventricle between patients with and without tumor wall MR contrast delayed enhancement(P>0.05);The time of adverse cardiovascular events in patients with delayed contrast enhancement of tumor wall MR was 86.50 months,significantly faster than 110.31 months in patients without delayed contrast enhancement of tumor wall MR(P<0.05);The incidence of adverse cardiovascular events in patients with delayed contrast enhancement of tumor wall MR was 50.00%,which was significantly higher than that in patients without delayed contrast enhancement of tumor wall MR(P<0.05).Conclusion MR contrast delayed enhancement of HCM with LVAA has certain clinical value,which is helpful to predict the prognosis of patients.
