Description

This study was designed to assess the effects of bariatric weight loss surgery on structural, functional, and inflammatory markers of coronary atherosclerosis. Obesity is a worldwide epidemic and an independent risk factor for coronary atherosclerosis. It remains unclear whether surgically induced weight loss reduces cardiovascular risk. This prospective study enrolled 50 consecutive subjects with morbid obesity who underwent Roux-en-Y gastric bypass surgery (GBS) after failed attempts at medical weight loss. Subjects were recruited through a comprehensive weight loss center affiliated with an academic tertiary care hospital. All subjects had body mass indexes \textgreater or =40 kg/m(2) or body mass indexes of 35 to 40 kg/m(2) with \textgreater or =2 co-morbid obesity-related conditions. Markers of coronary atherosclerosis, including brachial artery flow-mediated dilation, carotid intima-media thickness, and high-sensitivity C-reactive protein, were measured before GBS and 6, 12, and 24 months after GBS. There were statistically significant improvements in all measured markers of coronary atherosclerosis after GBS. The mean body mass index decreased from 47 to 29.5 kg/m(2) at 24 months (p \textless0.001), the mean carotid intima-media thickness regressed from 0.84 to 0.50 mm at 24 months (p \textless0.001), mean flow-mediated dilation improved from 6.0% to 14.9% at 24 months (p \textless0.05), and mean high-sensitivity C-reactive protein decreased from 1.23 to 0.65 mg/dl at 6 months (p \textless0.001) and to 0.35 mg/dl at 24 months (p \textless0.001). In conclusion, GBS results in significant improvements in inflammatory, structural, and functional markers of coronary atherosclerosis.
