NEW YORK  - For patients with several blockages in their coronary arteries, mortality rates are lower when they undergo bypass grafting rather than having the new generation of drug-eluting stents inserted, a study shows.

MONDAY, Dec. 4 (HealthDay News) -- Heart patients with drug-eluting stents implanted to keep their arteries open were found to have a much higher risk of sudden death than those getting bare metal stents if they stopped taking the blood thinner Plavix, a new Swiss study reports.

GAITHERSBURG, Maryland  - A U.S. advisory panel heard evidence on Thursday about risks of drug-coated stents, the tiny mesh tubes used to prop open arteries in millions of heart patients.

The two manufacturers of drug-coated stents used to prop open the arteries of about 3 million people in the U.S. say the devices' benefits outweigh their risks, even though patients could face a small but significant risk of blood clots.

November 8, 2004 -- Stents, the tiny mesh tubes placed at the site of just-cleared blockages in heart arteries, help reduce the need for more artery-clearing procedures, but have no impact on long-term survival of patients, new research report said

The most exhaustive studies yet published on drug-coated stents show that the widely used heart devices are no better at preventing heart attacks and death than the older, cheaper devices they replaced, and in some cases may be slightly worse.

Drug-coated stents may carry a delayed risk of potentially dangerous blood clots, according to a new report.

Patients given drug-coated stents after an acute heart attack are nearly 5 percent more likely to die a year or more later than those with bare metal forms of the arterial scaffolding, new research showed on Tuesday.

One of the nation's leading   cardiologists is calling for a sweeping study that evaluates   the risks of potentially fatal blood clots related to widely   used heart devices that treat blocked heart arteries.

Drug-coated stents that prop open the arteries of about 3 million people in the U.S. don't increase the risk of heart attack or death when used as labeled but may put patients at risk for blood clots, health advisers said Thursday.

A panel recommended that doctors and patients be given stronger warnings about the dangers associated with the use of drug-coated stents.

Drug-eluting stents are safe and   effective for use in patients who had severe heart attacks, but   the potential risk of blood clots needed more study before the   devices could be recommended for all heart attack patients,   according to an editorial in a major medical journal.
