New-generation oral anticoagulants (NOACs) are now preferred as a first-line treatment in the management of atrial fibrillation for prevention of thromboembolic complications. Mean platelet volume (MPV), one of the indicators of increased platelet activity, is also associated with an increased stroke risk in atrial fibrillation patients. The aim of this study was to evaluate changes in MPV, platelet distribution width (PDW) and plateletcrit following use of NOACs. The study included 116 patients with non-valvular atrial fibrillation without previous NOAC use. Complete blood counts, biochemical analyses and echocardiography were performed for all patients. No significant differences were observed in MPV or other platelet indices at 6 months compared to baseline. Our results indicate that MPV and other platelet indices are not affected by NOAC use in non-valvular atrial fibrillation patients.
