[Advanced myocardial ischemia in patients with diabetes mellitus--early results of surgical treatment].

In this restrospetive study, data on 272 coronary artery disease patients with concomitant diabetes mellitus treated between 12/1997 and 12/2002 were analyzed. Eighty patients inderwent complete arterial revascularization (DM-ART), whereas 192 patients underwent coronary revascularization using arterial-venous grafts (DN-NEART). The following preoperative data and risk factors were analyzed: arterial hypertension, hyperlipoproteinemia, number of vessels involved, left coronary artery stenosis, unstable angina, previous myocardial infarction (MI), previous cardiac surgery, EuroScore. During a 30-day postoperative period, the following complications were analyzed: bleeding, perioperative MI, wound infection, sternal dehiscence, neurologic dysfunction, mortality. DM-ART patients had a higher rate of hyperlipoproteinemia (p=0.004). Difference was only found for the occurrence of perioperative MI in DM-NEART group (p<0.001). Total arterial revascularization without cardiopulmonary bypass is a reliable and safe choice in patients with concomitant diabetes mellitus irrespective of its type. Definitive conclusions can only be made after five- or ten-year evaluation of postoperative mirbidity and mortality.
