Incremental value of right atrial strain for early diagnosis of hemodynamic deterioration in pulmonary hypertension: a new noninvasive tool for a more comprehensive diagnostic paradigma

摘要

Aims Increased right atrial size is related to adverse prognosis in pulmonary hypertension. The potential incremental value of right atrial function assessment is still unclear. We tested the relationship between right atrial two-dimensional speckle-tracking echocardiography impairment and hemodynamic, functional and clinical deterioration in patients with pulmonary hypertension.
