RESUMO
PURPOSE: High-dose steroid therapy (HDST) has frequent side-effects that appear at its cessation and depend on its dose. However, there is a lack of studies about the acute effects of HDST on cardiac function in adult patients. METHODS: We included in this study 30 patients who underwent HDST (intravenously at doses ranging from 250 to 1000 mg) and 30 healthy control subjects with similar demographic and clinical characteristics, between September and December 2016. Echocardiographic measurements were made before and during the first 3 hours after the end of treatment, and results were compared between patients and controls. RESULTS: There was no difference in baseline biochemical and echocardiographic characteristics between the patient and control groups. While left ventricular global longitudinal strain (LVGLS) and strain rate E were higher after treatment, no significant change was observed in conventional echocardiographic variables. CONCLUSIONS: LVGLS, but not conventional echocardiographic variables, showed an increase in cardiac systolic function at the acute phase of HDST.
