Diabetic Patients with Cardiovascular Disease Show More Metabolic Syndrome than Nondiabetic Patients: Multicentric Study in the Northeast of Brazil.

Diabetes mellitus (DM) is associated with a higher prevalence of metabolic syndrome (MS) and cardiovascular mortality. However, few Brazilian studies evaluated MS in diabetic individuals with cardiovascular disease (CVD). Nevertheless, the objective of this study was to compare the prevalence of MS in cardiac patients with and without DM. Cross-sectional study of BALANCE Program Trial with patients with CVD, ≥45 years old, who had been attending specialized ambulatories on cardiovascular health, in eight states in the Northeast of Brazil. The components of MS were evaluated by following the criteria of National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) and Joint Interim Statement (JIS). In addition, there were investigated different indexes of abdominal obesity, variables related to lifestyle, and food intake. The statistical analysis included descriptive statistics and the Student's -test, Mann-Whitney, and chi-squared tests for the comparison of groups. There were significant values of  < 0.05. Six hundred forty-seven individuals were evaluated with average (standard deviation) age of 63.1 (9.3) years, being 50.5% females and 40.3% diabetic patients. When the groups of patients who were diabetic and the nondiabetic ones, the first showed higher percentage of obesity (38.5% vs. 23.2%,  < 0.001), of high waist circumference (84.8% vs. 71.9%;  < 0.001), higher waist-height ratio [0.6 (0.6-0.7) vs. 0.6 (0.5-0.6);  < 0.001], conicity index [1.35 (1.29-1.39) vs. 1.32 (1.27-1.38);  = 0.004], and prevalence of MS, because of the criteria of NCEP ATP III (98.8% vs. 80.4%;  < 0.001), as well as the criteria of JIS (99.2% vs. 89.3%;  < 0.001). The component of higher frequency was high blood pressure and/or hypertension (95.0%), followed by hypertriglyceridemia (93.0%). There were no differences regarding age, lifestyle, and food intake. Diabetic individuals with CVD showed more prevalence of MS and more abdominal obesity than nondiabetic individuals. ClinicalTrials.gov ID: NCT01620398.
