研究目的:

本项目旨在构建一个针对肥厚型心肌病(HCM)的、基于常规心脏磁共振(CMR)序列的多中心智能分析系统。通过深度挖掘多中心历史影像数据库,开发多模态特征自动提取与融合算法,实现对HCM心肌异常区域与模式的精准识别、疾病亚型鉴别诊断、个体化猝死及心力衰竭等风险分层预测以及标准化结构化报告生成的核心功能。项目将利用多中心长期随访数据,验证模型对HCM患者主要不良结局事件(如心源性猝死及其相关事件、心力衰竭、房颤等心律失常、脑卒中、心脏移植、死亡等)的预测效能,最终形成一套可集成于临床工作流的HCM专病智能决策支持工具  

Objectives of Study:

This project aims to develop a multicenter intelligent analysis system for hypertrophic cardiomyopathy (HCM) based on routine cardiac magnetic resonance (CMR) sequences. By deeply mining multicenter historical imaging databases and developing automated multi-modal feature extraction and fusion algorithms, the project will achieve precise identification of abnormal myocardial regions and patterns in HCM, differential diagnosis of disease subtypes, individualized risk stratification prediction for sudden cardiac death and heart failure, as well as the core function of generating standardized structured reports. The project will utilize multicenter long-term follow-up data to validate the predictive performance of the models for major adverse outcomes in HCM patients (such as sudden cardiac death and related events, heart failure, atrial fibrillation and other arrhythmias, stroke, heart transplantation, and all-cause death). Ultimately, it will form a set of HCM-specific intelligent decision support tools that can be integrated into clinical workflows.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.患者符合《2024 AHA/ACC 肥厚型心肌病管理指南》中关于HCM的诊断标准,即心脏磁共振(CMR)显示左心室任意节段舒张末期最大室壁厚度(MWT)≥15 mm,或有明确HCM家族史者≥13 mm,且排除了其他可能导致心肌肥厚的原因(如高血压、主动脉瓣狭窄等);

Inclusion criteria

1.Patients meet the diagnostic criteria for HCM according to the 2024 AHA/ACC Guideline for the Management of Hypertrophic Cardiomyopathy, i.e., cardiac magnetic resonance (CMR) shows maximum wall thickness (MWT) ≥15 mm in any left ventricular segment at end-diastole, or ≥13 mm in those with a clear family history of HCM, after excluding other causes of myocardial hypertrophy (e.g., hypertension, aortic stenosis);
2.Age between 18 and 80 years;
3.Patients have complete and traceable key diagnostic and treatment records in the research center's information system available for extraction and analysis;

排除标准:

1.存在未控制的高血压、合并中度及以上瓣膜性心脏病、先天性心脏病、心肌梗死或经影像学证实的心外膜冠状动脉显著狭窄;
2.确诊为肥厚型心肌病拟表型,如法布里病(Anderson-Fabry病)、Danon病、心脏淀粉样变等;
3.既往接受过室间隔减容治疗(包括外科室间隔切除术或酒精消融术);
4.存在CMR检查禁忌证(如非兼容起搏器/植入式心律转复除颤器[ICD]、严重幽闭恐惧症、严重肾功能不全[eGFR < 30 mL/min/1.73m2]等),或因严重心力衰竭无法耐受平卧检查;
5.CMR图像质量差(如运动伪影严重、无法进行心肌应变分析或晚期钆增强[LGE]定量评估),影响后续数据分析;
6.临床关键数据(如基础诊断依据、核心影像学参数[LVEF]、预后终点信息)严重缺失且无法追溯补充;

Exclusion criteria:

1.Uncontrolled hypertension, moderate or severe valvular heart disease, congenital heart disease, myocardial infarction, or angiographically confirmed significant epicardial coronary artery stenosis;
2.Confirmed diagnosis of HCM phenocopies, such as Anderson-Fabry disease, Danon disease, or cardiac amyloidosis;
3.Prior septal reduction therapy (including surgical septal myectomy or alcohol septal ablation);
4.Contraindications to CMR examination (e.g., incompatible pacemaker/implantable cardioverter-defibrillator [ICD], severe claustrophobia, severe renal insufficiency [eGFR < 30 mL/min/1.73m2]), or inability to tolerate supine examination due to severe heart failure;
5.Poor CMR image quality (e.g., severe motion artifacts, inability to perform myocardial strain analysis or late gadolinium enhancement [LGE] quantitative assessment) affecting subsequent data analysis;
6.Critical clinical data (e.g., basis for diagnosis, core imaging parameters [LVEF], prognostic endpoint information) are severely missing and cannot be supplemented retrospectively;
