Abstract Background The evaluation of right ventricular (RV) function is clinically important in pulmonary hypertension (PH) because of prognostic implications. Conventional echocardiography has been used to predict adverse outcomes in chronic PH, but there were certain limitations arising from the complexity of RV anatomy. We used strain rate imaging (SRI) to evaluate RV function in PH patients. Methods Study population consisted of 50 patients (mean age 46 ± 13 years; 39 females) with chronic PH who underwent echocardiography including SRI within 24 h of right heart catheterization. Mean value of peak systolic longitudinal strain obtained from basal and mid RV free wall were calculated. Reduced RV systolic contraction (fractional area change
