Cardiovascular Adverse Events Associated with Tumor Necrosis Factor-Alpha Inhibitors: A Real-World Pharmacovigilance Analysis.

aimEvidence regarding the association between various tumor necrosis factor-α (TNF-α) inhibitors and cardiovascular adverse events (AEs) is both limited and contradictory.

methodsA retrospective pharmacovigilance study was conducted using the FDA Adverse Event Reporting System (FAERS) database. Cardiovascular AEs associated with TNF-α inhibitors (adalimumab, infliximab, etanercept, golimumab, and certolizumab) were evaluated using a disproportionality analysis. To reduce potential confounders, adjusted ROR and subgroup analyses were performed.

resultsAfter excluding duplicates, 9,817 cardiovascular reports were associated with the five TNF-α inhibitors. Only adalimumab had positive signals for myocardial infarction (ROR=1.58, 95%CI=1.51-1.64) and arterial thrombosis (ROR=1.54, 95%CI=1.49-1.58). The remaining four TNF-α inhibitors did not show a risk association with any type of cardiovascular event. Further analyses of specific indication subgroups and after adjusting for any confounding factors demonstrated that adalimumab was still significantly associated with cardiovascular events, especially in patients with psoriasis (adjusted ROR=2.16, 95%CI=1.95-2.39).

conclusionsThis study revealed that adalimumab was the only TNF-α inhibitor associated with an elevated risk of thrombotic cardiovascular AEs, whereas the other four TNF-α inhibitors did not show any risk effect. However, given the limitations of such pharmacovigilance studies, it is necessary to validate these findings in prospective studies in the future.
