Doctors say diabetics with several clogged heart arteries fare better with bypass surgery instead of having stents placed to open up blood vessels.
Doctors compared the treatments in a study of 1,900 diabetics and looked five years later to see how many had suffered a heart attack, stroke or died.
Only 19 percent of the bypass group had as opposed to 27 percent of those who received stents.
The results are in the New England Journal of Medicine.
