“That is a polymer which degrades into water and carbon dioxide during a period of six to nine months after the drug has been released and renders the stent surface more closely to a bare-metal stent," he said.
A year later, the researchers found those who got the drug-eluting stent had fewer heart problems than those who received the bare-metal variety.
“The occurrence of new heart attacks within that treated segment was slower with the biodegradable polymer as compared to the bare-metal stent, and it reduces the incidences of serious cardiovascular events by more than 50 percent," said Windecker.
Dr. Windecker says these newest drug-eluting stents made with polymers that dissolve are better than other medicated stents made with polymers that don't dissolve.
Ideally, a layer of cells that lines the artery will grow over the stent, making it, in a sense, part of the body.
The study was published in the Journal of the American Medical Association.
