Synopsis

Keywords: Heart, Cardiovascular, Heart failureTo investigate the relationship correlation of cardiac magnetic resonance (CMR) feature tracking (FT)-derived right ventricular (RV) global longitudinal strain (RV-GLS) and RV global circumferential strain (RV-GCS) with mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) to explore the diagnostic value of RV strain parameters in advanced left heart failure patients with pulmonary hypertension (PH). Study findings included as following: (a) CMR-FT RV-GLS and RV-GCS were independent risk factors for PH in patients with end-stage left heart disease, among all CMR imaging parameters; (b) Both RV-GCS (AUC = 0.868) and RV-GLS (AUC = 0.873) were valuable in predicting PH.
