Prognostic Value of Right Ventricular Global Wasted Work in Precapillary Pulmonary Hypertension : A 3D Echocardiographic Study
AIM: Right ventricular (RV) function determines symptom burden and clinical outcomes in pulmonary hypertension (PH). Global wasted work (GWW) quantifies mechanical inefficiencies in RV performance associated with elevated afterload, but is inadequately characterized in precapillary PH. We assessed the association of GWW with echocardiographic indices of RV remodeling, RV-PA coupling and invasive h
