African-Americans Have Higher Risk for Blood Clots After Receiving Drug-Coated Stent

African-American race is among the risk factors for developing dangerous blood clots after receiving a drug-coated stent.
Despite taking anti-clotting medications as directed, African-Americans had more than double the rate of clotting compared to other races.
African-American race is a distinct risk factor for developing life-threatening blood clots after receiving a drug-coated stent, according to research reported in Circulation: Journal of the American Heart Association.
African-American race was the strongest predictor of clotting that occurs more than 30 days after implantation, researchers said.
For the study, researchers examined data on 7,236 patients who had stents, coated with clot-prevention drugs, implanted to prop open narrowing arteries. The drug-coated stents, also called drug-eluting stents, were implanted between mid-2003 and the end of 2008.
Even after considering other known risk factors — such as diabetes, hypertension and kidney problems — researchers found that African-Americans still experienced a higher rate of thrombosis or clotting.
The bottom line is this is not just because this population is sicker or less compliant, but there is something else there that needs to be explored,” said Ron Waksman, M.D., the study’s lead author. Read the rest of this entry »
