One in 20 ischemic strokes occurs soon after withdrawal of antithrombotic agents, warn researchers. They report that 5.2% of all stroke patients in a single year had an antithrombotic or antiplatelet agent withdrawn within the previous 60 days. Many went on to have strokes within 7 days of withdrawal.
"Physicians need to be aware of the risks associated with stoppage of antithrombotic medications in patients who are planning to undergo a medical or dental procedure where there is risk of bleeding," lead investigator Joseph Broderick, MD, from the University of Cincinnati told Medscape Medical News.
