Global Wasted Work Identifies Decompensated Right Heart Failure and Predicts Outcomes in Precapillary Pulmonary Hypertension: A 3D Echocardiographic Study

AIM. Right ventricular (RV) function plays an important role in determining symptom burden and clinical outcomes in pulmonary hypertension (PH). Global Wasted Work (GWW) quantifies mechanical inefficiencies in RV performance associated with elevated a
