Vitamin K Supplementation in Patients on Hemodialysis

Summary

The purpose of this study is to determine whether vitamin K supplementation will improve anticoagulation control in patients on hemodialysis taking warfarin for atrial fibrillation. Patients who participate will receive vitamin K1 three times a week on dialysis days for a period of four months. INR levels collected during this period will be compared to the four month period prior to receiving the vitamin K1 to determine if vitamin K improves the standard deviation of INRs and time in therapeutic range.
