Ties Between Medical Device Industry, Stent Doctors Questioned

The New York Times reports that heart doctors and makers of medical devices meeting for their annual Transcatheter Cardiovascular Therapeutics convention were made aware that two senators are asking tough questions about financial ties between the doctors and the companies.
The Times says lawmarkers Charles E. Grassley, Republican of Iowa, and Herb Kohl, Democrat of Wisconsin, sent a letter asking the nonprofit group that sponsors the conference, the Cardiovascular Research Foundation, for information about its financial relationships with device manufacturers and drug producers. The senators also sent a letter to Columbia University, which has an affiliation with the Cardiovascular Research Foundation. Two well-known researchers at Columbia, Dr. Martin B. Leon and Dr. Gregg W. Stone, are involved with the foundation; Dr. Leon is its former chairman and Dr. Stone its current one.
In their letter to the foundation, the lawmakers also took note of a comment in an article published last November in The New York Times. In the article, a researcher, Dr. Jeffrey W. Moses, who serves on the board of the Cardiovascular Research Foundation, said that the safety of heart stents “is not the big issue any more.”
The senators wrote: “As you are no doubt aware, there are divergent scientific opinions concerning such products, the safety and efficacy of which are a matter of dispute among cardiologists.”
The letter to the Cardiovascular Research Foundation asked the group to disclose all financing it had received since 2003 from the five device manufacturers named in the letter and also to provide documentation of any payments and benefits the foundation had provided to 22 researchers including Dr. Stone, Dr. Leon and Dr. Moses. The lawmakers asked Columbia to provide information about the disclosures those researchers had made to the institution about their income from industry sources.
At the same conference on Thursday, researchers released results of a new study indicating that a drug-coated stent called Endeavor, made by Medtronic, was linked to more heart attacks and deadly blood clots than the Cypher stent made by Johnson & Johnson.
