Abstract

Objective: Left atrial (LA) dysfunction is a crucial risk factor for cardiovascular events, and various pathologies may affect LA function. Coronavirus disease-2019 (COVID-19) is an ongoing global pandemic causing morbidity and mortality. In the present study, we aimed to evaluate LA functions in patients who recovered from COVID-19.

Methods: Sixty consecutive patients recovered from COVID-19 and 60 healthy individuals as a control group were included in the study. Blood samples and echocardiography measurements were obtained from each subject. The two groups were compared in terms of demographic and echocardiographic characteristics.

Results: In the COVİD-19 group, LA maximum volume (LAV) ( = 0.040), LA pre-A volume (LAVpre-A) ( = 0.014), and LA active emptying fraction ( = 0.027) were higher, while LA passive emptying fraction ( = 0.035) was lower. In addition, left ventricular ejection fraction ( = 0.006) and isovolumetric relaxation time ( = 0.008) were decreased in this group. Although LA volume index was higher in the COVID-19 group, it does not reach statistical significance.

Conclusion: LA functions may be impaired in patients recovered from COVID-19 infection.
