Drug-Coated Stents Help Patients at Highest Risk of Repeat Procedures
Much controversy has developed in recent months about the safety and potential complications of drug-eluting heart stents increasing the risk of possible fatal blood clots, even years after an angioplasty procedure. However, a new study led by investigators from Ontario’s Institute for Clinical Evaluative Sciences (ICES) and McMaster University’s Program for Assessment of Technologies in Health, tells a different story.
Described in the October 4, 2007 issue of New England Journal of Medicine, the study found that drug-eluting stents were most effective in reducing the need for repeat angioplasty procedures or bypass surgery in angioplasty patients at the “highest risk” for a renarrowing of the artery around the stent, without significantly increasing the rate of death or risk of heart attack. Lead author, ICES Senior Scientist Dr. Jack Tu says, “This is good news, reassuring patients and cardiologists about the...
