Diabetes increases mortality after bypass

Reported by Susan Aldridge, PhD, medical journalist

A study shows that people with type 2 diabetes are more at risk of dying after they have a heart bypass.
When someone has blocked arteries, there are two options - angioplasty or a bypass. Both are effective but the latter is often preferred in severe heart disease and among those with type 2 diabetes. But researchers at the Bethesda Family Residency Program in Cincinnati, Ohio, now sound a note of caution.

They studied nearly 7,000 patients undergoing heart bypass, of whom one third had type 2 diabetes. In the month following the surgery, mortality among the diabetic patients was 3.9 per cent, compared to just 2.6 per cent among those who did not have diabetes.

After taking other risk factors into account, those with diabetes had a 67 per cent higher mortality risk after their heart operation. What is more, the diabetic patients also had more kidney and wound problems and a longer hospital stay. The researchers think that increased blood sugar may be the factor that worsens the outlook for diabetic patients after surgery.
