OBJECTIVES: To assess the differences in the parameters that are metabolically related to cardiovascular diseases after weight loss in obese people with coronary artery diseases (CADs).

METHODS: This study was conducted on 184 patients who were diagnosed with CADs in Istanbul University Cardiology Institute Hospital, Istanbul, Turkey. The levels of leptin, fibrinogen, homocysteine, high-sensitivity C-reactive protein (hs-CRP), triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol (LDL-C), fasting blood glucose and insulin, glycated hemoglobin, and uric acid of the obese patients who were put on calorie restricted diet were evaluated retrospectively and compared before and after weight loss. For comparison, non-obese control patients were also studied. Student's t-test and Chi-square test were used for the statistical analysis. Results: Levels of homocysteine, glycated hemoglobin, and leptin were significantly higher in the obese patients than in the non-obese patients. Diabetic obese patients with CADs lost (11.1%) and non-diabetic obese patients with CADs lost (10.5%) of their body weight in 6 months. The levels of cholesterol, LDL-C, and fibrinogen were significantly improved in both groups. Conclusion: The obese patients lost weight after being on calorie-restricted diets and showed significant improvement in the levels of cholesterol, LDL-C, fibrinogen. There was no significant difference in the levels of homocysteine, hs-CRP, and leptin before and after weight loss in both diabetic and non-diabetic obese patients.
