Study design:

Cohort study 

研究目的:

利用4D flow CMR技术探索肥厚型心肌病(包括梗阻及非梗阻)患者左心室KE及血流组分参数变化特点,以ACC/AHA HCM 风险模型为参考,初步建立4D-flow技术在HCM患者中风险分层阈值,并对患者进行MACE事件随访,探索预测不良事件的血流动力学标志物。  

Objectives of Study:

Utilizing 4D flow CMR technology, this study investigates the characteristics of left ventricular kinetic energy (KE) and blood flow component parameters in patients with non-obstructive hypertrophic cardiomyopathy (HCM), including both obstructive and non-obstructive subtypes. Using the ACC/AHA HCM risk model as a reference, we aim to preliminarily establish risk stratification thresholds based on 4D-flow parameters in HCM patients. Follow-up for major adverse cardiac events (MACE) will be conducted to identify hemodynamic biomarkers predictive of adverse outcomes.
