What are the cardiopulmonary exercise test (CPET) findings and longitudinal changes in young athletes with persistent symptoms following COVID-19 compared to healthy athletes?
CPET is a useful clinical tool to evaluate and track recovery in young athletes with persistent cardiopulmonary symptoms after COVID-19, who generally lack active inflammatory heart disease.
OBJECTIVES: Persistent or late-onset cardiopulmonary symptoms following COVID-19 may occur in athletes despite a benign initial course. We examined the yield of cardiac evaluation, including cardiopulmonary exercise testing (CPET), in athletes with cardiopulmonary symptoms after COVID-19, compared CPETs in these athletes and those without COVID-19 and evaluated longitudinal changes in CPET with improvement in symptoms. METHODS: This prospective cohort study evaluated young (18-35 years old) athletes referred for cardiopulmonary symptoms that were present>28 days from COVID-19 diagnosis. CPET findings in post-COVID athletes were compared with a matched reference group of healthy athletes without COVID-19. Post-COVID athletes underwent repeat CPET between 3 and 6 months after initial evaluation. RESULTS: and oxygen pulse, and reduction in resting and peak heart rate (all p<0.05). CONCLUSION: Despite a high burden of cardiopulmonary symptoms after COVID-19, no athlete had active inflammatory heart disease. CPET was clinically useful to reproduce symptoms with either normal testing or identification of abnormal spirometry as a potential therapeutic target. Improvement in post-COVID symptoms was accompanied by improvements in CPET parameters.
