متن کاملRight ventricular diastolic impairment in patients with pulmonary arterial hypertension.
BACKGROUND The role of right ventricular (RV) diastolic stiffness in pulmonary arterial hypertension (PAH) is not well established. Therefore, we investigated the presence and possible underlying mechanisms of RV diastolic stiffness in PAH patients. METHODS AND RESULTS Single-beat RV pressure-volume analyses were performed in 21 PAH patients and 7 control subjects to study RV diastolic stiffn...
