ABSTRACT
PURPOSE:
The aim of the present study was to investigate the effect of intensive antidiabetic therapy on vascular indices in type 2 diabetes mellitus (T2DM) patients.METHODS:
Poorly controlled T2DM patients (n = 62, mean age 64 years, T2DM duration 14 years, HbA1c ≥ 7.5%) were studied at baseline and following intensive treatment to achieve optimal glycemic control. Brachial artery flow-mediated dilation, carotid-femoral pulse wave velocity, central augmentation index, large and small (C2) artery compliance, carotid intima-media thickness (cIMT), and ankle-brachial index were assessed at baseline and follow-up.RESULTS:
HbA1c decreased from 8.8% (8.1, 10.1) (median, interquartile range-IQ) to 7.4% (6.9, 7.8), p < 0.001. Triglycerides and high-sensitivity C-reactive protein levels were decreased by ~ 10% and 50%, respectively (p < 0.05). Maximum cIMT and C2 increased at follow-up (0.97 ± 0.25 to 1.03 ± 0.27 mm and 3.3 (2.7, 4.2) to 4.2 (3.2, 5.4) ml/mmHg × 10, respectively, p < 0.05). In subgroup analysis, the observed changes in vascular indices were not affected by diabetes duration, presence of cardiovascular disease, or insulin treatment.CONCLUSION:
In patients with long-standing T2DM, short-term aggressive glycemic control was associated with an improvement of microvascular function (C2) and deterioration of carotid atherosclerosis (IMT) without any effect on the elastic properties of large arteries.Palavras-chave
