Original Article Luo et al Right ventricular function by 2D-STE in SLE Arq Bras Cardiol. 2018; 111(1):75-81 Figure 1 – Longitudinal peak systolic strain (ε) curve was obtained in right ventricular free wall for basal, middle and apical segment by 2D-STE from the apical four‑chamber view. (A) group A; (B) group B (systemic lupus erythematosus – SLE, without pulmonary hypertension); (C) group C (SLE with mild pulmonary hypertension); (D) group D (SLE with moderate-to-severe pulmonary hypertension). Conclusion In conclusion, 2D-STE-derived strain and SR imaging could early detect the RV dysfunction in SLE patients with PH, especially in those with mild PH. This has an important value in guiding early therapy in clinical settings, improving the prognosis, and increasing the quality of life of SLE patients with PH.
