Right Ventricular Dysfunction in Lung Disease/Hypoxia-Associated Pulmonary Hypertension.

ABSTRACT:

Background

Limited data exist on right ventricular (RV) function in lung disease/hypoxia-associated pulmonary hypertension (PH). We aimed to clarify the presence, characteristics, and clinical significance of RV dysfunction in patients with lung disease/hypoxia-associated PH.

Methods

We analyzed data from 3 groups of patients: those with lung disease/hypoxia-associated PH, those without PH, and those with pulmonary arterial hypertension (PAH). RV volume was assessed using cardiac magnetic resonance imaging, and RV pressure data were obtained by right heart catheterization and analyzed using dedicated software and a single-beat method. We then evaluated RV contractility by end-systolic elastance (Ees), diastolic function by β and end-diastolic elastance, and RV-pulmonary arte
