Pulmonary arterial hypertension (PAH) has a subtle onset, rapid progression, and high mortality rate. Imaging evaluation is an important diagnostic and follow-up method for PAH patients. Right ventricular (RV) strain evaluation can identify early changes in RV function and predict the prognosis. Currently, various methods such as tissue Doppler imaging, velocity vector imaging, speckle tracking imaging, and cardiac magnetic resonance imaging can be used to evaluate RV strain in PAH patients. This article aims to summarize the research progress of RV strain imaging evaluation technology in PAH patients, in order to provide a basis for clinical diagnosis and follow-up of PAH patients.
肺动脉高压(PAH)起病隐匿,进展迅速,死亡率高。影像学评估是PAH患者重要的诊断及随访方法。右心室(RV)应变评估可识别RV功能的早期变化并预测预后。目前,组织多普勒成像、速度向量成像、斑点追踪成像及心脏磁共振成像等多种方法可用于评估PAH患者的RV应变。本文旨在总结PAH患者RV应变成像评估技术的研究进展,为PAH患者的临床诊断及随访提供依据。
