Article in the Wall Street Journal -- Stent Implants Declined in April: Doctors Attribute Drop To Study Showing Drugs May Have Similar Benefits, by Keith J. Winstein. Here's an excerpt:
The number of coronary stents implanted in the U.S. dropped sharply in April, according to a leading market researcher, in what doctors said was an unusually quick response to a study showing the devices provided little advantage over drug therapy in some patients.
The new figures are the latest evidence that the tiny scaffolds used to prop open arteries are no longer a powerful growth engine for the medical industry. Americans spent at least $14 billion on coronary-stent procedures last year, including surgical and hospital fees. World-wide sales of the devices totaled about $6 billion.
Doctors performed about 71,200 stentings in April, according to estimates from Millennium Research Group, a Toronto firm that surveys about 140 U.S. hospitals. That was down more than 10% from March and down more than 15% from a year earlier.
Boston Scientific Corp., one of the three main stent makers, said it believed that the effect would be temporary. Abbott Laboratories, of Abbott Park, Ill., said it hadn't seen a decline in its own market data, and Johnson & Johnson, based in New Brunswick, N.J., declined to comment on the new figures.
