Numerical but non-significant differences were also observed between both control groups, with the fully recovered patients presenting with higher heart rates and lower HRV than the uninfected subjects. The role of antiplatelet agents such as aspirin as an alternative (or in conjunction with anticoagulation agents) for thromboprophylaxis in COVID-19 has not yet been defined and is currently being investigated as a prolonged primary thromboprophylaxis strategy in those managed as outpatients (ACTIV4 (NCT04498273)).
