Methods
This prospective study was conducted during Iran’s third COVID-19 wave in November 2020 among health care workers who were infected with COVID-19 but otherwise healthy. A total of 100 patients underwent echocardiographic examination six to eight weeks following recovery, an early follow-up. Six months after the COVID-19 diagnosis, as the late follow-up, 63 subjects underwent echocardiographic evaluations. Moreover, based on clinical and radiological evidence, individuals were categorized into two groups of non-severe and severe COVID-19.
