JCHF 2013;1:290-299 Survival of HFREF Patients With PH (A) Kaplan-Meier estimates of survival in patients with heart failure of reduced left ventricular ejection fraction (HFREF) relative to passive pulmonary hypertension (PH) and mixed PH as defined by pulmonary vascular resistance (PVR) < or ≥3.0 Wood units (WU) and no PH. (B) Kaplan-Meier estimates of survival in patients with HFREF relative to passive PH and mixed PH as defined by transpulmonary gradient (TPG) < and ≥12 mm Hg and no PH. Wayne L. Miller et al.
