【摘要】 扩张型心肌病(dilated cardiomyopathy，DCM)是以左心室或双心室扩张并伴有心脏收缩功能障碍为特征的心肌病。DCM患者的病死率高且预后差，但随着心脏磁共振成像(cardiac magnetic resonance imaging，CMR)技术的发展，其能更精确评估左心房体积、左心室体积、左心室舒张末期容积指数、左心室射血分数(left ventricular ejection fraction，LVEF)等心脏参数，早期诊断DCM，辅助治疗方案制订，有助于患者预后改善。此外，CMR因良好的软组织对比度和高空间分辨率等特点，在DCM患者的预后预测中极具优势。本文综述了CMR评估DCM患者预后的研究进展及价值。

    Value of Cardiac Magnetic Resonance Imaging in Evaluating the Prognosis of Dilated Cardiomyopathy/Saiyaremu Xierzhati， LI Jie. //Medical Innovation of China， 2025， 22(06)： -178

    [Abstract] Dilated cardiomyopathy (DCM) is a cardiomyopathy characterized by dilation of the left or both ventricles accompanied by systolic dysfunction. Patients with DCM have high mortality and poor prognosis， but with the development of cardiac magnetic resonance imaging (CMR) technology， it can more accurately evaluate left atrial volume， left ventricular volume， left ventricular end-diastolic volume index， left ventricular ejection fraction (LVEF) and other cardiac parameters， diagnose DCM early， assist in the formulation of treatment plans， and contribute to the improvement of patients' prognosis.
