Multimodal Framework of Left Heart–Pulmonary Vascular Remodeling Underlying Right Ventricular Failure in PH-HFpEF
Background: Right ventricular (RV) dysfunction in pulmonary hypertension due to heart failure with preserved ejection fraction (PH-HFpEF) leads to adverse outcomes, yet the mechanisms underlying RV failure remain incompletely defined. We aimed to develop a multimodal framework integrating vascular mechanics and myocard...
