New Israeli research suggests Plavix, a blood thinner often used in place of the troublesome clot buster Coumadin, doesn’t work in many of the heart patients it’s designed to help.While Plavix doesn’t appear to actually harm patients, about a quarter of those studied failed to respond to it, according to the small study. But the fact that Plavix (clopidogrel) still works much of the time indicates that it remains a good weapon for doctors to use, said cardiologist Dr. Stephen Wiviott, who co-wrote a commentary about the findings in the June 7 online issue of Circulation.
