therapeutic approach for severely obese patients. Carotid intima-media thickness (CIMT) and brachial artery flow-mediated dilation (FMD)provide important prognostic information beyond traditional CV risk factors. This study aimed to examine the effect of bariatric surgery-inducedweight loss on CIMT and brachial artery FMD in morbidly obese patients.Methods: A total of 23 morbidly obese patients (40.4±5.6 years, 13 females) were examined before and after BS for 1 year with 3-month periods.CIMT, FMD, body composition, and metabolic parameters were determined.Results: All the patients exhibited significant weight loss following BS (p<0.001). Carotid intima-media thickness reduction was not significantfrom baseline to 6 months (p=0.069), but at 9 months (p=0.004), it became significant. Similarly, the difference between the preoperative and6-month FMD assessments was not significant (p=0.057), but at 9 months (p<0.001), it became significant.Conclusion: Our study reveals that weight loss following BS causes improvements in CV risk factors, which is evident after 9 months of surgery.(Anatol J Cardiol 2020; 23: 218-22)
