Choice to use drug-eluting stents has little relation to patients' probable benefit

A new study found that using drug-eluting stents has little relation to patients' predicted risk of restenosis. Reducing unnecessary usage could significantly cut US health costs and prevent complications. The authors suggest incorporating assessment of restenosis risk into regular practice for better-informed decisions.
