Pulmonary Hypertension Is Related to Peripheral Endothelial Dysfunction in Heart Failure With Preserved Ejection Fraction

Study Questions:

Peripheral endothelial dysfunction (PED) has been described in heart failure (HF) and in pulmonary arterial hypertension (PAH). Is PAH associated with PED and impaired collagen metabolism in patients with HF with preserved ejection fraction (HFpEF)?
