Diastolic Pressure Gradient Predicts Outcome in Patients With Heart Failure and Preserved Ejection Fraction

Approximately 50% of patients presenting with clinical signs of heart failure are diagnosed with heart failure with preserved ejection fraction (HFpEF) [(1)][1]. Pulmonary hypertension (PH) is a common feature of HFpEF and predicts poor outcome. According to the diastolic pressure gradient (DPG)
