Value of speckle-tracking echocardiography changes in monitoring myocardial dysfunction during treatment of sepsis: potential prognostic implications

This study assessed STE at admission and during the treatment of patients with sepsis to evaluate its changes as a potential factor for predicting in-hospital outcome. This study included 26 patients with sepsis who underwent STE echocardiography on day 1 and 7 during treatment. Myocardial deformation of both ventricles was assessed using global longitudinal strain. The endpoint was in-hospital mortality. The mean age was 51.4  ± 18.3 years, and 54% were female. The average SOFA score at T0 was 8.6 ± 3.8 points and at day 7 was 4.9 ± 4.7 points. The left ventricular (LV) ejection fraction at baseline was 65.6 ± 9.1%, without changes in echocardiographic parameters during treatment. LV and RV longitudin al strain increased significantly in the patients who survived (− 18.8 ± 3.6 at D1 vs − 20.8 ± 2.5 at D7; p = 0.003; and − 21.3 ± 4.9 at D1 vs − 24.3 ± 5.8 at D7; p = 0.035, respectively), whereas strain values remained unchanged in those who died. After adjustment for the SOFA score, RV longitudinal strain at admission was associated with in-hospital mortality [adjusted odds ratio (OR) 0.760; 95% confidence interval (CI) 0.591–0.977; p − 0.033]. STE improved significantly after the first week of treatment in patients with sepsis who survived compared with those patients who died during hospitalization. RV strain at admission predicted in-hospital mortality. An improvement in STE during sepsis treatment appe...
