Right ventricular dysfunction in systemic sclerosis-associated pulmonary arterial hypertension.
BACKGROUND Systemic sclerosis–associated pulmonary artery hypertension (SScPAH) has a worse prognosis compared with idiopathic pulmonary arterial hypertension (IPAH), with a median survival of 3 years after diagnosis often caused by right ventricular (RV) failure. We tested whether SScPAH or systemic sclerosis–related pulmonary hypertension with interstitial lung disease imposes a greater pulmo...
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...

متن کاملClinical relevance of right ventricular diastolic stiffness in pulmonary hypertension.
Right ventricular (RV) diastolic stiffness is increased in pulmonary arterial hypertension (PAH) patients. We investigated whether RV diastolic stiffness is associated with clinical progression and assessed the contribution of RV wall thickness to RV systolic and diastolic stiffness. Using single-beat pressure-volume analyses, we determined RV end-systolic elastance (Ees), arterial elastance (E...
متن کاملLeft Ventricular Diastolic Dysfunction in Pediatric Pulmonary Hypertension.
Pulmonary hypertensive vascular disease (PHVD) is characterized by progressive narrowing of pulmonary arterioles, abnormally high pulmonary vascular resistance (PVR), right ventricular (RV) dysfunction, left ventricular (LV) compression, and death in ≈25% to 60% of patients with pulmonary arterial hypertension (PAH) 5 years after diagnosis. Meanwhile, consensus statements have been developed in...
