Pulmonary hemodynamics in heart failure patients with reduced or preserved ejection fraction and pulmonary hypertension: Similarities and disparities

Our findings suggest that for similar levels of PAWP, pulmonary circulation may be stiffer in patients with HFpEF-PH than patients with HFrEF-PH, leading to higher DPGs. Nonetheless, PCa rather than DPG emerged as the stronger predictor of survival in both left-sided PH phenotypes.
