Why the study?
Assessment of right atrial function may have prognostic value in pulmonary hypertension, but studies on this subject remain scarce.
Does two-dimensional Doppler echocardiography reveal differences in myocardial strain of the right atrium in patients with precapillary pulmonary hypertension compared to healthy controls?

This study aims to evaluate right atrial myocardial strain using echocardiography in patients with precapillary pulmonary hypertension, which may have prognostic value.

RA strain assessment may aid prognostication in precapillary PH; leaves open its clinical utility without further validation.
Background: Considering that the effect of right ventricular (RV) failure on the right atrium (RA) is an essential part of the pathophysiology of pulmonary hypertension (PH), the assessment of RA function seems to have prognostic value in the course of the disease, but there are still few studies on this subject. Objective: To evaluate myocardial strain of the RA in patients with precapillary PH. Methods: This is an observational, longitudinal, prospective study involving 36 patients with precapillary PH, in whom two-dimensional Doppler echocardiography was performed. A control group consisting of 26 healthy individuals was used.
