VIENNA, Sept 4 (Reuters) - Patients given drug-coated stents after an acute heart attack are nearly five times more likely to die six months to two years later than those with bare metal forms of the arterial scaffolding, research showed on Tuesday.The finding, from a two-year analysis of 2,300 patients in 14 countries, fuels the debate over the safety of so-called drug-eluting stents, made by the likes of Boston Scientific (BSX.N: Quote, Profile, Research) and Johnson & Johnson (JNJ.N: Quote, Profile, Research).
