ABSTRACT
BACKGROUND AND AIM: One of the main causes of mortality among obese patients is cardiovascular disease (CVD). Carotid intima-media thickness (CIMT) is an independent predictor for atherosclerosis and risk of CVD, and has been demonstrated to be related with obesity. This study aimed to evaluate the effect of substantial weight loss after bariatric surgery on CIMT.
METHODS: This prospective study was performed on patients with morbid obesity and standard indications for bariatric surgery in a tertiary referral center in Iran. The mean CIMT values were assessed using B-mode ultrasonography before and 6 months after bariatric surgery.
RESULTS: A total of 32 patients (25 females, 7 males) with a mean age of 38.18 ± 1.18 years were enrolled. Body mass index (BMI) was significantly reduced from 43.66 ± 6.44 to 29.01 ± 2.56 kg/m2 during 6 months following surgery (p: 0.001). The mean CIMT values at 6 months after surgery were significantly lower than the baseline (0.53 ± 0.06 vs. 0.50 ± 0.08; p: 0.001). Along with a significant hypertension and metabolic syndrome remission, we observed considerable reduction in FBS (p: 0.019), cholesterol (p: 0.061), triglycerides (p: 0.001), and insulin levels (p: 0.001). Besides, liver stiffness was significantly decreased after surgery (6.15 ± 0.82 vs. 5.26 ± 0.83; p: 0.001). There was no statistically significant correlation between changes in quantitative variables and changes in CIMT.
CONCLUSION: Bariatric surgery results in significant reduction in CIMT, metabolic syndrome factors, and liver stiffness in patients with morbid obesity.
