AFRICA CARDIOVASCULAR JOURNAL OF AFRICA • SAHS Biennial Congress 16-18 September 2022 54 Submission ID: 1359 Introduction Global Longitudinal Strain (GLS) is a new and sensitive ultrasound indicator of left ventricular (LV) systolic function. It can not only assess the evolution of LV systolic function if it is impaired, but also predict the risk of future events in this population. Thus, what is its place in the prognosis of moderately reduced ejection fraction heart failure (mrVEF). Methods This is a prospective study of 6 months of HF patients with LVEF (40%-50%). LMS was assessed by two-dimensional speckle-tracking software on echocardiography. We recorded any cardiovascular events requiring or not requiring hospitalization and reported on LMS and LVEF. Results Among the 102 patients with HFimpEF, the median absolute values of SGL and LVEF were 14.1% (12.5%-16.7%) and 44% (40%-50%) respectively. In the 6 months following the baseline echocardiogram any 1% increase in SGL on echocardiography was associated with a lower probability of the composite endpoint of: heart failure in 73%; atrial fibrillation in 25%; intra left ventricular thrombus in 2%. Conclusion In patients with HFimpEF, GLS is an important predictor of cardiovascular events.
