Long-term Mortality in Diabetics Undergoing Major Surgery

Diabetes mellitus is an important risk factor for arteriosclerosis in general and for coronary artery disease. Patients with CAD have a worse prognosis if they have diabetes mellitus. But it is not known whether the treatment of Dm has an influence on mortality or morbidity. In face of the high number of patients with Dm and the therapeutic consequences this prospective study wants to compare short-time and long-time morbidity in Patients with Dm undergoing major non-vascular surgery. Inclusion criteria are medically treated Dm (insulin or oral antidiabetics) and major non cardiac surgery. The "normal" perioperative treatment of the study is not changed by the study itself.
