A blood pressure medication can cut the risk of stroke in people who have atrial fibrillation, a type of irregular heartbeat that can cause blood clots to form, researchers conclude.Researchers reporting Thursday in the journal Stroke found that use of the antihypertensive drug perindropil -- an ACE inihibitor -- improved patients’ health even if they were already taking anticoagulants to keep their blood thin.The study followed 476 patients with atrial fibrillation. Risk of a major stroke decreased 41 percent in patients who already were on anticoagulants, and 34 percent in patients who were not.
