Vitamin K antagonists’ risks and benefits in the oldest patients


Use of vitamin K antagonists in patients aged 90 years or older was associated with a slight increase in the risk of bleeding compared with patients in their 70s. The risk of thrombosis was higher in patients in their 90s and 80s compared with those in their 70s, according to results of a matched cohort study published online in JAMA Internal Medicine.
