Support for the Resumption of Training of High-level Athletes Post-epidemic COVID-19

An ECG at rest is performed for all participants at Day 0. A centralized reading is performed by one of the 6 expert cardiologists participating in the research.

In case of positive COVID-19 serology and/or positive COVID-19 RT-PCR and/or new ECG abnormality and/or positive questionnaire, a stress test is performed.

In case of positive COVID-19 serology and/or positive COVID-19 RT-PCR and/or new ECG abnormality and/or positive questionnaire, a Cardiac echocardiography is performed.

In case of positive COVID-19 serology and/or positive COVID-19 RT-PCR and/or new ECG abnormality and/or positive questionnaire, a Cardiac rhythm monitoring is performed.

To determine the rhythmic risk of athletes

"High resolution MRIs is performed on 200 athletes :~* 100 athletes without rhythmic abnormalities (50 individuals with positive COVID-19 status and 50 individuals with negative COVID-19 status)~* 100 athletes with rhythmic abnormalities (50 individuals with positive COVID-19 status and 50 individuals with negative COVID-19 status)"

"For all athletes included at the D0 inclusion visit, a centralized COVID-19 serology is performed to search for biomarkers associated with the occurrence of myocardial fibrosis: analysis of genetic determinants in relation to cardiac damage.~For athletes who have performed MRI: Search for biomarkers associated with the occurrence of myocardial fibrosis: analyses of low-grade inflammation markers (cytokine assay and fibrosis markers)."
