  • Data are scarce on the effect of amiodarone on warfarin sensitivity and related outcomes after placement of a left ventricular assist device (VAD). This retrospective study compared 30-day outcomes between patients on amiodarone vs no amiodarone after VAD implant. After exclusions, 220 patients received amiodarone and 136 patients did not. Com-pared to the no amiodarone group, the amiodarone group had a higher warfarin dosing index (0.53 [0.39, 0.79] vs 0.46 [0.34, 0.63]; P = 0.003), incidence of INR > 4 (40.5 vs 23.5%; P = 0.001), incidence of bleeding (24.1 vs 14%; P = 0.021), and use of INR reversal agents (14.5 vs 2.9%, P < 0.001). Amiodarone was associated with bleeding (OR, 1.95; 95% CI, 1.10-3.47; P = 0.022), but not after adjusting for age, estimated glomerular filtration rate, and platelet count (OR, 1.67; 95% CI, 0.92-3.03; P = 0.089). After VAD implant, amiodarone was associated with increased warfarin sensitivity and administration of INR rever-sal agents.
