Use of non-vitamin K oral anticoagulants in people with atrial fibrillation and diabetes mellitus.

AIMS

To examine the efficacy and safety of non-vitamin K oral anticoagulants in people with both atrial fibrillation and diabetes mellitus.

METHODS

We reviewed efficacy and safety data from the warfarin-controlled phase III non-vitamin K oral anticoagulants trials (ARISTOTLE, RE-LY, ROCKET-AF, ENGAGE AF-TIMI 48) and their post hoc analyses with regard to diabetes status. We also reviewed the updated literature regarding this population.

RESULTS

At baseline 20-40% of the participants in the phase III non-vitamin K oral anticoagulants trials had diabetes mellitus at baseline. This population, in comparison with those without diabetes, was more likely to have other comorbidities, such as hypertension and coronary artery disease; thus, their cardiovascular risk was higher. Participants with diabetes had higher rates of stroke and systemic embolism than participants without diabetes. This risk was decreased using non-vitamin K oral anticoagulants, with no significant interaction by diabetic status or the specific drug used. Overall, compared with warfarin, non-vitamin K oral anticoagulants were safe and reduced the incidence of major bleeding in people with atrial fibrillation and diabetes, although the results varied with the different non-vitamin K oral anticoagulants.

CONCLUSIONS

The efficacy and safety of non-vitamin K oral anticoagulants compared with warfarin generally extend to participants with diabetes mellitus, although dedicated randomized trials or real-world data are lacking.
