BACKGROUND: COVID-19 induces a pro-coagulant state with thrombotic events. This meta-analysis explores the efficacy and safety of antiplatelet-based therapy in COVID-19 patients through randomized controlled trials (RCTs).
MATERIALS AND METHODS: A systematic literature search until March 10, 2023, identified 7 RCTs involving 23,415 inpatients. Of these, 11,891 received antiplatelet-based treatment, and 11,524 received placebo/other drugs. Statistical analysis was performed using Review Manager 5.4.
RESULTS: The included trials involved patients with a mean age ranging from 54.3 to 62.0 years and a prevalence of hypertension ranging from 10.9 to 65.0% and coronary artery disease ranging from 3.2 to 32.7%. The pooled analysis showed no significant difference in overall mortality between groups (RR 1.0, 95% CI 0.99 - 1.01, p = 0.76). However, antiplatelet therapy significantly reduced major thrombotic events (RR 0.86, 95% CI 0.75 - 0.99, p = 0.04). Conversely, it increased major bleeding risks (RR 1.62, 95% CI 1.24 - 2.12, p = 0.0005). There was no significant difference in the incidence of invasive mechanical ventilation and respiratory death.
CONCLUSION: Antiplatelet therapy does not confer mortality benefit in COVID-19 patients but lowers major thrombotic events while increasing major bleeding risks. Ongoing large RCTs will provide more information on the therapeutic value of this therapy.
