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. |

纳入标准: |
1.短暂性左心室功能障碍,特征为心尖气球样变或中心室、基底或局灶性室壁运动异常,可能涉及右心室; 2.局部室壁运动异常通常超出单个心外膜血管的分布范围; 3.情绪、身体或复合触发因素可能先于TTS发生(非必需); 4.神经系统疾病和嗜铬细胞瘤可作为TTS的诱因; 5.出现新的心电图异常:在大多数情况下,心脏生物标志物(肌钙蛋白和肌酸激酶)的水平适度升高;脑利钠肽(BNP)显著升高; 6.严重的冠状动脉疾病(CAD)与TTS并不矛盾; |
||||||||||||||||||||||
|
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. |
