Cardiac Function in Uncomplicated COVID-19 Survivors: Correspondence

To the Editor,

We would like to share ideas on the publication “Evaluation of Cardiac Function in Uncomplicated COVID-19 Survivors by 2-Dimensional Speckle Tracking Imaging.”¹ Akbulut et al¹ noted that the study is valuable in putting forth the unaffected ventricular and atrial functions on long term in uncomplicated COVID-19 cases and may decrease the survivors’ anxiety and the number of unnecessary applications to cardiology clinics. We agree that COVID-19 can cause several health problems including cardiac problem.² The alteration of cardiac function in COVID-19 survivors is possible, and the present study showed good data. However, it is necessary to recognize the confounding effect. There might be a co-morbidity in the COVID-19 survivor which might occur before or after COVID-19 illness. Additionally, the effect of COVID-19 vaccination, which might be given prior to or after COVID-19 illness, should also be mentioned.
