Sustained Impairment in Cardiopulmonary Exercise Capacity Testing in Patients after COVID-19: A Single Center Experience

<div>Physical capacity, O<sub>2</sub> pulse, V̇E, and peak V̇O<sub>2</sub>/kg at first and second CPET (in %). Analysis performed with Student’s <i>t</i>-test for related variables; mean value (±standard deviation). V̇E: respiratory minute volume and peak V̇O<sub>2</sub>/kg: body weight-indexed oxygen uptake.</div>
