Metabolic syndrome was defined and operationalized when three or more of the following were present for the patient: abdominal obesity ("waist circumference, >102 cm [>40 inches] in men or >88 cm [>35 inches] in women"); glucose intolerance; hypertension; or high density lipoprotein cholesterol (p. 469). These definitions are integral for providing inclusion criteria for the study and for evaluating the data based on gender.
Research Design The research design used for the investigation was a retrospective observational study which was carried out in the cardiac department of Winchester Medical Center in Virginia. Specifically medical record reviews were used as a principle tool for evaluating patient status at the time of surgery and the outcomes which resulted following CABG. All patients undergoing CABG had their charts reviewed to determine if they met the criteria for metabolic syndrome. The period for the inclusion of patients in the study was from January 1, 2005 through June 30, 2006. Patients were excluded from the study if they met any of the following criteria: under the age of 18, receiving valve replacement with CABG, were dependent on dialysis or had concomitant procedures such as "transmyocardial revascularization, carotid endarterectomy, atrial ablation surgery, or repair of an abdominal aortic aneurysm" (p. 470).
