Abstract Objective: To assess the left ventricular systolic function using the longitudinal peak strain(S) and strain rate(Sr) with two-dimensional(2D) speckle tracking technique and evaluate its clinical value in patients with systemic lupus erythematosus(SLE). Methods: Thirty SLE patients and 32 control subjects underwent the examination of echocardiography. 2D images were recorded in apical four chamber, two chamber and apical long axis view from the left ventricle. The global peak S and Sr and the peak S and Sr of segments were obtained in the above views using 2D speckle tracking technique. Results: The Tei index was increased in SLE patients(P<0.001). The global peak S and Sr and the peak S and Sr of segments were decreased in SLE patients(P<0.05). Conclusions: The global and regional left ventricular longitudinal systolic function is weakened in patients with SLE. 2D Speckle tracking technique is an accurate way for assessing the left ventricular systolic function.
