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.
