Doctors Rethink Widespread Use of Heart Stents - NYT[ Link ]
But now stent sales are falling and some doctors are rethinking their faith in the devices, driven by emerging evidence that the newest and most common type — drug-coated stents — can sometimes cause potentially fatal blood clots months or even years after they are implanted.
The Food and Drug Administration said yesterday that it would hold hearings in early December to consider whether to issue new stent safety guidelines.
The evidence indicates that overuse of stents may be leading to thousands of heart attacks and deaths each year, whether because stents are being used in relatively mild cases where drugs should be prescribed instead, or because patients are receiving drug-coated versions where simpler, cheaper bare-metal devices might work just as well.
There is no question that stents have saved countless lives in the short term by preventing impending heart attacks or opening arteries while an attack is being treated. But neither type of stent, no matter how much better it may make a patient feel, has been shown in rigorous clinical trials to improve long-term survival compared with other forms of treatment.

The new evidence has added to a long-simmering debate over whether doctors have been too quick to prescribe stenting — whether because drugs would work as well for healthier patients or because bypass surgery might help the sickest ones live longer.
