Direct Oral #Anticoagulants in Atrial Fibrillation Patients with Concomitant #Hyperthyroidism

Patients with hyperthyroidism were excluded from randomized clinical trials of direct oral anticoagulants(DOACs) for stroke prevention in patients with non-valvular atrial fibrillation (NVAF)..

After PSSW, DOAC had a comparable risk of ischemic stroke/systemic embolism (IS/SE) and a lower risk of major bleeding (hazard ratio (HR):0.65; [95% confidential interval (CI):0.44-0.96]; P=0.0295) than warfarin among patients with hyperthyroidism. There were comparable risks of IS/SE and major bleeding between those patients with and without hyperthyroidism. However, patients taking warfarin with hyperthyroidism had a lower risk of IS/SE than those without hyperthyroidism (HR:0.61; [95%CI:0.43-0.86]; P=0.0050).

Conclusion

Among NVAF Asian patients with concomitant hyperthyroidism, DOACs may be an effective and safer alternative to warfarin. Thromboprophylaxis with DOACs may be considered for such patients, and it is important to validate this finding in further prospective study
