ABSTRACT
Background:
Aspirin at low doses has been reported to be a potential drug candidate to treat or prevent severe coronavirus disease 2019 (COVID-19).Objectives:
We aimed to explore whether low-dose aspirin used for primary cardiovascular prevention was associated with a lower risk of severe COVID-19.Method:
A large cohort of patients without known cardiovascular comorbidities was constructed from the entire French population registered in national health care databases. In total, 31.1 million patients aged ≥40 years, including 1.5 million reimbursed for low-dose aspirin at least at three time points during the 6 months before the epidemic, were followed until hospitalization with a COVID-19 diagnosis or intubation/death for hospitalized patients.Results:
Cox models adjusted for age and sex showed a positive association between low-dose aspirin and the risk of hospitalization (hazard ratio [HR], 1.33; 95% confidence interval (CI), 1.29-1.37]) or death/intubation (HR, 1.40 [95% CI, 1.33-1.47]). In fully adjusted models, associations were close to null (HR, 1.03 [95% CI, 1.00-1.06] and 1.04 [95% CI, 0.98-1.10], respectively).Conclusion:
There was no evidence for an effect of low-dose aspirin for primary cardiovascular prevention in reducing severe COVID-19.
