研究目的:

1.主要目的:构建DMD患儿心肌病进展的纵向轨迹模型,识别关键转折点(如LGE出现、纵向应变异常、LVEF下降),并评估多模态影像学与实验室指标对于预测2-3年内发生心脏事件(LVEF<50%、心衰症状、心脏原因住院或死亡)的预测效能。 2.次要目的:① 比较不同CMR或LGE状态分组在基因型、激素治疗情况、NSAA评分、六分钟步行实验、实验室指标(CK、BNP、肌钙蛋白、尿蛋白)等方面的差异。 ② 分析心脏功能时间-变化曲线,划分临床阶段(如EF正常无LGE、EF正常伴LGE/应变异常、EF轻度下降、EF明显下降伴症状),探讨各阶段与年龄、基因型、运动功能(NSAA、6MWT)、实验室指标、药物治疗方案及时机的关联。 ③ 评估糖皮质激素与心肌药物联合治疗的时机与方案对远期预后的影响。  

Objectives of Study:

1. Primary Objectives:To construct a longitudinal trajectory model for the progression of cardiomyopathy in pediatric patients with Duchenne muscular dystrophy (DMD), identifying key transition points (e.g., the emergence of late gadolinium enhancement [LGE], abnormalities in longitudinal strain, and decline in left ventricular ejection fraction [LVEF]).To evaluate the predictive efficacy of multimodal imaging and laboratory indicators for forecasting cardiac events (defined as LVEF <50%, symptoms of heart failure, hospitalization due to cardiac causes, or death) within 2–3 years. 2. Secondary Objectives:(1). To compare differences in genotype, steroid treatment status, North Star Ambulatory Assessment (NSAA) scores, six-minute walk test (6MWT) results, and laboratory indicators (creatine kinase [CK], B-type natriuretic peptide [BNP], troponin, and urinary protein) among groups categorized by cardiac magnetic resonance (CMR) or LGE status.(2). To analyze time-varying curves of cardiac function, delineate clinical stages (e.g., normal EF without LGE, normal EF with LGE/strain abnormalities, mild EF decline, significant EF decline with symptoms), and explore the associations between these stages and factors such as age, genotype, motor function (NSAA, 6MWT), laboratory indicators, and the timing and regimen of pharmacological interventions.(3). To assess the impact of the timing and regimen of combined glucocorticoid and cardioprotective therapy on long-term prognosis.
