Drug-Eluting Stents Help Save Lives Five Years Out

A drug-eluting stent (DES), a mesh tube that can help prop open arteries after they are widened by balloon angioplasty, is more helpful than a bare-metal stent in preventing death and heart attacks for up to five years, according to a new study. Drug-eluting stents release medication that helps prevent arteries from re-closing.

A survival analysis of more than 6,500 patients treated between April 1, 2004 and the end of 2008 revealed that cumulative death rate for the patients who received DES was 12.85 percent, or “significantly lower” than 14.14 percent in the bare-metal stent group. A sub-analysis of those who died showed that cardiac death was the cause for nearly half of the bare-metal stent patients versus just over one-third of the DES patients.

In addition, just 5.17 percent of the DES patients had heart attacks, or myocardial infarction (MI), compared to 5.83 percent of those with bare-metal stents.

The study was conducted by researchers led by Tamir Bental, MD, of Rabin Medical Center in Israel. The article appears in the September issue of Catheterization and Cardiovascular Interventions.

Question for comment: Have you or someone you know had a drug-eluting stent for five years or more?
