ABSTRACT
PURPOSE: While most coronavirus disease 2019 (COVID-19) cases are mild, the risk of heart dysfunction remains unknown. The objective of this observational study was to assess the impact of mild COVID-19 on heart function in a short-term follow-up using advanced echocardiography. METHODS: Our study cohort comprised patients diagnosed with COVID-19 who did not require hospitalization. Speckle tracking echocardiography (STE) was used to assess heart chambers function in the 31 recovered COVID-19 patients, and the results were compared with those of the control group (28 healthy participants). RESULTS: Left ventricular (LV) and right ventricular (RV) systolic function was assessed using standard and STE methods and was found to be normal and comparable in both groups (LV ejection fraction [p = 0.075], LV global longitudinal strain [p = 0.123], LV global radial strain [p = 0.630], LV global circumferential strain [p = 0.069], tricuspid annular plane systolic excursion [p = 0.417], tricuspid S' peak systolic velocity [p = 0.622], and RV free wall longitudinal strain [p = 0.749]). Similarly, atrial function was not impacted when assessed using advanced STE. CONCLUSIONS: The heart function of patients with mild COVID-19 symptoms, assessed using standard and advanced echocardiographic methods, was observed to be normal after a short-term follow-up.
