I have thrombocytosis.can i continue to eat foods high in vitamin k?if so, will i be at risk for cva or mi?

Yes: Vitamin k merely keeps your clotting factors normal. This is a whole different division from the platelet department, and in fact interfering with these doesn't protect about the problems that thrombocytosis may cause. Your physician can manage your thrombocythosis -- i'm guessing you have essential thrombocythemia -- often the best treatment is "do nothing." best wishes.
