New blood thinner shows promise


WATERLOO (KWWL) -- A new study shows promising results for a blood thinner called Rivaroxaban.  The study shows it was as successful as Coumadin (another blood thinner) at treating strokes in people with a common heart rhythm, known as Atrial Fibrillation.

Rivaroxaban was tested against a generic version of Coumadin in more than 14,000 people with Atrial Fibrillation.  That's the most common heart rhythm problem in America. It occurs when the upper parts of the heart quiver instead of beating normally. This raises the risk of clots that can cause a stroke.

Johnson & Johnson and Bayer Healthcare plan to seek federal approval to sell the drug later this year. Doctors gave results of the study Monday at a heart conference in Chicago.
