Predictors of Warfarin Time in Therapeutic Range after Continuous‐Flow Left Ventricular Assist Device

Abstract

Patients with a continuous‐flow left ventricular assist device (CF‐LVAD) require anticoagulation with a vitamin K antagonist to prevent thromboembolic events. Fluctuations in the international normalized ratio are associated with both increased thrombotic and bleeding episodes. To date, risk factors for low time in therapeutic range (TTR) among ambulatory patients with a CF‐LVAD have not been explored.
