The present study aims at assessing long-term hemostatic profile of patients recovered from COVID-19 acute infection that remain asymptomatic (POST-COVID) versus patients with residual symptoms (LONG-COVID) through the employment of a commercially available new generation point-of-care viscoelastic device. The primary endpoint is based upon the hypothesis that patients with residual symptoms maintain an abnormal coagulation profile even after recovery from COVID-19.

Inclusion Criteria:

• age > 18 years;
• recovery from acute COVID-19 infection;
• COVID-19 pneumonia that required hospitalization in our Institution;
• discharge from the hospital minimum 3 months before the day of the visit;
• written consent to participate to the study.

Exclusion Criteria:

• none.

The list of the patients hospitalized in our Institution due to COVID-19 pneumonia (positive COVID-19 test and radiological pneumonia diagnosis) was retrieved. The patients were recruited through a phone contact, those who were reachable and agreed to participate received an appointment for the in-person study-related procedures at our Hospital. The eligible patient population was represented by subjects hospitalized at out Institution for COVID-19 infection between January 1, 2021, and July 31, 2022. The planned patient population was 100 patients. The final patient population comprised 102 subjects.

The original dataset supporting the findings of this study will be deposited in the public repository Zenodo after the publication of the paper and accessible upon a reasonable request to the Principal Investigator.
