Abstract

The aim of the current study was to evaluate the use of two‑dimensional strain echocardiography (2DS) in quantifying right ventricular (RV) function in patients with pulmonary arterial hypertension (PAH). A total of 41 patients with PAH and 40 healthy control patients were recruited to the study. 2DS was used to determine the strain (ε) and strain rate (SR) of basal, middle and apical segments of the RV free wall. The aforementioned indicators were compared with measurements of RV function taken by conventional ultrasound and right heart catheterization. The ε and SR of all segments of the right ventricular free wall were significantly lower in the PAH group, as compared with the control group (P<0.05). In the PAH group, the ε and SR of the middle and apical segments were significantly lower compared with basal segments (P<0.01). The SR of the apical segments were positively correlated with the area and diameter of the right ventricular. The ε of the apical segments were positively correlated with RV area, diameter and systolic function. The ε and SR of apical segments were positively correlated with pulmonary artery pressure and pulmonary vascular resistance measured by right heart catheterization. These findings indicated that 2DS can accurately evaluate RV longitudinal systolic function.
