Study design:

Sequential 

研究目的:

(1)构建首个整合多模态CMR定量参数(结构、功能、组织、微循环)和临床数据的TTS预后预测模型。 (2)通过SHAP框架解析模型,识别驱动高危预后的关键CMR特征组合,为病理机制研究提供新方向。 (3)经多中心验证证实模型普适性,形成可临床落地的TTS个体化风险分层工具。  

Objectives of Study:

(1) Construct the first TTS prognostic prediction model integrating multimodal CMR quantitative parameters (structural, functional, tissue, microcirculation) and clinical data. (2) Identify key CMR feature combinations driving high-risk prognosis through the SHAP framework parsing model, providing a new direction for pathomechanism research. (3) Confirm the generalizability of the model through multi-center validation, and form a clinically implementable individualized risk stratification tool for TTS.

Inclusion criteria

1.Transient left ventricular dysfunction characterized by apical ballooning or mid-ventricular, basal, or focal wall motion abnormalities, potentially involving the right ventricle; 2.Localized wall motion abnormalities typically extend beyond the distribution of a single epicardial vessel; 3.Emotional, physical, or combined triggering factors may precede TTS onset (non-essential); 4.Neurological disorders and pheochromocytoma may serve as precipitating factors for TTS; 5.New-onset ECG abnormalities: Moderate elevation of cardiac biomarkers (troponin and creatine kinase) in most cases; marked elevation of brain natriuretic peptide (BNP); 6.Severe coronary artery disease (CAD) is not incompatible with TTS;

排除标准:

1.合并由CMR证实的其他心脏疾病如肥厚型心肌病、心脏结节病、致心律失常性右室心肌病等; 2.年龄小于18岁; 3.中途随访中断或随访失联; 4.图像不完全或图像伪影影响后处理的患者; 5.肾功能不全的患者

Exclusion criteria:

1.Combination of other cardiac diseases confirmed by CMR such as hypertrophic cardiomyopathy, cardiac nodular disease, arrhythmogenic right ventricular cardiomyopathy, etc. 2.Age less than 18 years old; 3.Interruption of follow-up in the middle of the follow-up or loss of follow-up; 4.Patients with incomplete images or image artifacts affecting post-processing; 5. Patients with renal insufficiency.

测量指标:

Outcomes:

指标中文名:

不良心血管事件

指标类型:

主要指标

Outcome:

Adverse Cardiovascular Events

Type:

Primary indicator

测量时间点:

从基线CMR检查后开始,持续随访至少24个月

测量方法:

通过系统查阅医院的电子病历系统(包括住院记录、门诊记录、手术记录、死亡登记等)进行终点事件判定。对于病历信息不全的患者,将通过结构化电话随访进行补充。所有终点事件由不知晓患者基线CMR数据的临床研究协调员进行判定。

Measure time point of outcome:

Follow up for at least 24 months starting from baseline CMR examination

Measure method:

Determine the endpoint event by reviewing the hospital's electronic medical record system (including inpatient records, outpatient records, surgical records, death registration, etc.) through the system. For patients with incomplete medical records, supplementary information will be provided through structured telephone follow-up. All endpoint events were determined by clinical study coordinators who were unaware of the patient's baseline CMR data.

指标类型:

主要指标

Outcome:

Multimodal Quantitative CMR Parameters

Type:

Primary indicator

测量时间点:

基线(需在急性发作期2周内完成CMR检查)

测量方法:

使用3.0T心脏磁共振扫描仪进行标准化图像采集,所有图像由独立的核心实验室采用商用软件(如Circle cvi42)进行盲法后处理与分析,具体测量参数包括:1、结构与功能参数: 左心室射血分数(LVEF)、左心室舒张末期容积指数(LVEDVi)、左心室质量指数(LVMi);右心室射血分数(RVEF)。2、组织特征参数:水肿: Native T1值、T2值、T2-STIR高信号范围。纤维化: 细胞外

Measure time point of outcome:

Baseline (CMR examination must be completed within 2 weeks of acute exacerbation)

Measure method:

Standardized image acquisition was performed using a 3.0T cardiac magnetic resonance scanner, and all images were blindly processed and analyzed by an independent core laboratory using commercial software (such as Circle cvi42). Specific measurement parameters include: 1. Structural and functional parameters: left ventricular ejection fraction (LVEF), left ventricular end diastolic volume index (LVEDVi), left ventricular mass index (LVMi); Right ventricular ejection fraction (RVEF). 2.
