Sex-specific differences in echocardiographic parameters of risk stratification in pulmonary arterial hypertension.

Background: In healthy subjects, sex-differences in right heart function have already been detected for various echocardiographic parameters.

Research Question: The objective of the study was to investigate sex-differences in echocardiographic ESC/ERS risk stratification parameters and their impact on survival estimation in patients with pulmonary arterial hypertension (PAH).

Study Design And Methods: In this retrospective, cross-sectional study with a mean follow-up time of 3.

Long-term oxygen therapy in precapillary pulmonary hypertension - SOPHA study.

Current guidelines recommend oxygen (O) supplementation in patients with pulmonary hypertension (PH), despite scarce data on long-term O therapy (LTOT). The aim of this prospective, randomized, controlled trial was to investigate the effect of LTOT in patients with precapillary PH on exercise capacity, clinical parameters and hemodynamics. Patients with precapillary PH under stable therapy and O desaturations at rest and/or during exercise were randomized to receive LTOT (≥ 16 h/day) or no O (control group) for 12 weeks.

Association between right heart size and right ventricular output reserve in patients with pulmonary arterial hypertension.

Objectives: Right ventricular (RV) output reserve, defined as increase of cardiac output during exercise, is reduced in patients with pulmonary arterial hypertension (PAH). Aim of this study was to evaluate the association of right heart size measured by echocardiography and invasively measured RV function at rest and during exercise in PAH patients.

Methods: Adult PAH-patients who received routine haemodynamic assessment at rest and during exercise by right heart catheterisation and echocardiographic measurement of right heart size (right atrial (RA) and RV area) were included in this study.

Effect of ambrisentan in patients with systemic sclerosis and mild pulmonary arterial hypertension: long-term follow-up data from EDITA study.

Background: In the EDITA trial, patients with systemic sclerosis (SSc) and mild pulmonary vascular disease (PVD) treated with ambrisentan had a significant decline of pulmonary vascular resistance (PVR) but not of mean pulmonary arterial pressure (mPAP) vs. placebo after six months. The EDITA-ON study aimed to assess long-term effects of open label therapy with ambrisentan vs.

[General measures and management of pulmonary arterial hypertension].

Care of patients with pulmonary arterial hypertension (PAH) needs a multi-facetet concept and measures, including management of adverse reactions, right heart insufficiency as well as information on pregnancy, travels by air, psychosocial support, physical exercise training and prophylaxis by vaccination.Positive study results led to an higher recommendation of specialized exercise training in pulmonary hypertension. Also, the recommendation on iron substitution was amended according to the current evidence.
