Cardiopulmonary exercise test with stress echocardiography in COVID-19 survivors at 6 months follow-up

Although many studies suggest different degrees of myocardial and pulmonary injury during the acute infection and early follow-up 1–3,there is disagreement about cardio-pulmonary injury and functional impairment due to Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) during mid-term follow-up 4–8. We attempt to evaluate the cardiopulmonary function and assess the pulmonary and myocardial injury objectively in SARS-CoV-2 survivors.
