Medium-term glycemic control in diabetics before coronary bypass surgery.

ABSTRACT

The aim of this study was to determine the association between preoperative medium-term (60-90 days) glycemic control, as reflected by glycosylated hemoglobin levels (HbA1c), and the incidence of major complications (mediastinitis, perioperative infarction, heart failure, stroke and kidney failure dialysis) and mortality in diabetic patients undergoing elective coronary artery by-pass graft surgery (CABG). This study suggests that aggressive glycemic control three months before surgery, achieving HbA1c=7% improvement results with less postoperative morbidity and mortality.
