Fewer deaths with drug stents than bare metal: study

"Drug-coated stents implanted into clogged heart arteries are associated with a significantly lower risk of death than bare-metal versions, researchers at the Cleveland Clinic said on Monday. Use of stents coated with drugs to prevent scar tissue from reclogging arteries cleared of plaque has fallen as much as 50 percent in recent years due to concerns the tiny wire-mesh tubes can cause blood clots long after they are implanted" - Reuters
