|October 1, 1984
Abstract:
A 35-year-old woman was receiving warfarin sodium therapy for a prosthetic aortic valve. She sustained a myocardial infarction five weeks after beginning a diet of lettuce, broccoli, and turnip greens to lose weight. Excess dietary vitamin K can cause life-threatening consequences in patients on warfarin treatment.
