Angioplasty More Dangerous for Patients with Diabetes

The results of new research shows that people with diabetes have a higher chance of death after undergoing angioplasty.

Eric Van Belle, MD, PhD, of the University of Lille in France explained that fatality could be avoided by inserting a wire or stent in the artery during surgery to keep it from closing.

The research, published in the March 6 issue of Circulation: The Journal of the American Heart Association, indicated that angioplasty, or surgery of the arteries, has a higher chance of leading to death in diabetic patients. The fatal reaction takes place, they say, when the arteries become re-blocked after the surgery—a condition called restenosis.

The French researchers followed over 500 people with diabetes who underwent an angioplasty operation. In the cases when partial or complete (occlusive) restenosis took place six months after the procedure, there was a higher incidence of death.

“This is the first study to show that occlusive restenosis has a clinical relevance, and is one of the strongest predicators of [death after angioplasty] in the diabetic population,” Van Belle wrote in a statement from the America Heart Association.

Van Belle added, “This study indicates that [people with diabetes] should be treated differently from the general population, and may lead to new therapies to target re-blocking, or restenosis, in that group.”
