Risk of Blood Clots Leads to Continuing Drop in Use of Drug-Coated Stents

Article in the Wall Street Journal -- Market Share Slips for Drug-Coated Stents, by Keith J. Winstein.  Here's an excerpt:

The market share for drug-coated coronary stents slipped to 70.1% in February, marking the sixth straight month of decline, according to a survey by a market-research firm that surveys U.S. hospitals.

Doctors continued to pare back their usage in favor of plain, bare-metal stents over fears that the drug-coated variety can cause blood clots in some patients.

Last month, doctors in the U.S. used a drug-coated stent in only 72.5% of their procedures, according to Millennium Research Group, a Toronto research firm that surveys 140 U.S. catheterization labs where stenting procedures are typically performed. The share of stent procedures differs from the share of stents used because doctors often implant more than one stent at a time.

The share of procedures that use coated stents was the lowest since the stents were introduced in 2003 and 2004, and down from highs near 90% in early 2006.
