Prognostic value of pulmonary hemodynamic variables in heart failure patients with reduced ejection fraction(HFrEF) and pulmonary hypertension

Objective To investigate the survival of different subgroups of pulmonary hypertension due to left heart disease(PH-LHD)in heart failure patients with reduced ejection fraction(HFrEF)and to detect possible hemodynamic variables associated with the prognosis of these patients.
