Objective To evaluate the right ventricular function with speckle tracking imaging(STI) and tissue Doppler imaging(TDI) in patients with systemic sclerosis(SSc).Methods Thirty-five patients with SSc(SSc group),and 40 healthy subjects(NOR group) were enrolled.Strain was performed using STI and TDI,the peak strain was calculated in the basal,middle and apical segments of right free wall.Results Compared with NOR group,peak strain parameters decreased in SSc group(P0.05).Strong correlation was found between strain calculated with STI and TDI(P0.01).Conclusion Right ventricular function decreases in patients with systemic scleroderma.STI and TDI may accurately evaluate right ventricular function.
