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.
