AimTo investigate whether Roux-en-Y gastric bypass surgery (RYGB) – an in vivo model for normalisation of hyperglycaemia – improves carotid intima-media thickness (IMT) in patients with type 2 diabetes (T2D)/impaired glucose tolerance (IGT) and normal glucose tolerance (NGT).MethodsObservational prospective study, 34 obese patients (T2D (n = 14)/IGT (n = 4), and NGT (n = 16)) were investigated before and six and 12 months after RYGB.ResultsMean carotid IMT was significantly reduced 12 months after RYGB in patients with T2D/IGT (− 0.041 mm (95% CI − 0.069; − 0.012, p = 0.005)) but not in patients with NGT (− 0.010 mm (− 0.039; 0.020, p = 0.52)). The between-group difference was not significant (p = 0.13). Twelve months after RYGB, patients with respectively T2D/IGT and NGT demonstrated changes in weight: − 29.9 kg, p < 0.001/− 30.6 kg, p < 0.001, HbA1c: − 0.7%, p < 0.001/− 0.1%, p = 0.33, systolic blood pressure: − 2 mmHg, p = 0.68/− 10 mmHg, p = 0.01 and diastolic blood pressure: − 8 mmHg, p = 0.003/− 11 mmHg, p < 0.001. 80% of T2D patients terminated antihyperglycaemic medication.ConclusionMean carotid IMT was significantly reduced 12 months after RYGB in patients with T2D/IGT which provides evidence to support that the earliest atherosclerotic changes in the arterial wall are reversible. Although numerically different from the changes observed in patients with NGT, the between-group difference was not statistically significant.
