Stent Failure: How Much of the Problem Is Caused by Doctors? (2/2)

So far, researchers have mostly investigated the stents themselves and how they are made. But now attention is turning also to the way they are being used. The question is how much of the problem of stent failure may be the result of stents not being put in right. Or maybe they are not being expanded enough to fit firmly in the artery.

One recent study found that stents were incorrectly placed in almost seventy percent of the patients in that study.

Now a heart research organization hopes to solve the mystery. The Cardiovascular Research Foundation is a big supporter of the use of drug-treated stents. The foundation is going to carry out a large study. Spokeswoman Irma Damhuis says it will involve eleven thousand patients at ten centers in the United States and two in Germany. A heart doctor with the foundation will be one of the lead investigators.

Researchers will examine how doctors implant and expand stents and how the methods they use might affect outcomes. The study will deal especially with serious artery blockages that have been found a year or more after a stent was put in place.
