We retrospectively evaluated the echocardiographic data of ambrisentan-treated patients with pulmonary arterial hypertension (PAH) (NCT01808313).Change from baseline in right ventricle (RV) systolic function, right heart structure, and pulmonary artery systolic pressure (PASP) prognosis to Weeks 12 and 24 was evaluated by echocardiography.In the overall population, the mean tissue Doppler-derived tricuspid lateral annular systolic velocity (S') increased by 0.6 cm/s at both Weeks 12 (p 0.001) and 24 (p = 0.004) and tricuspid annular plane systolic excursion increased by 0.13 cm at Week 12 and 0.15 cm at Week 24 (both p 0.001). A marked decrease in transverse and longitudinal RV and RA diameter at Weeks 12 and 24 was observed. A significant decrease in diastolic eccentricity index at both Weeks 12 (-0.1; p = 0.02) and 24 (-0.1; p = 0.001). The decrease in PASP from baseline was significant at both Weeks 12 (-9.5 mmHg; p0.001) and 24 (-7.6 mmHg; p0.001), while a decrease in the estimated right atrium pressure was found to be significant at Week 24 (-0.8mmHg; p = 0.01).Significant improvements in a number of RV echocardiographic parameters were observed at Weeks 12 and 24 after ambrisentan treatment in patients with PAH.
