Patients with controlled postoperative blood sugar

All heart surgery patients get their blood sugar checked after surgery. Any patient who has high blood sugar after heart surgery has a greater chance of getting an infection. This measure tells how often the blood sugar of heart surgery patients was kept under good control in the days right after their surgery.

Why is it important?

Even if heart surgery patients do not have diabetes, keeping their blood sugar under good control after surgery lowers the risk of infection and other problems. "Under good control" means their blood sugar should be 200 mg/dL or less when checked first thing in the morning.
