Study: Extended anti-clotting therapy cut heart attacks after stent
Patients who took two anti-clotting drugs for 30 months after undergoing a heart stent placement significantly cut their risk of heart attacks and blood clots in the stent compared with patients receiving the dual therapy for the standard 12 months, a clinical trial showed. In this five-year study of nearly 10,000 patients who had received drug-coated stents in an artery clearing procedure, the rate of heart attacks was 2.1 percent for those who received dual anti-clotting therapy for 30 months. The rate was 4.1 percent for those who got aspirin and a placebo after 12 months of dual therapy, researchers reported. That translated to 20 fewer heart attacks per 1,000 patients treated.
