Plasma copeptin and markers of arterial disorder in patients with type 2 diabetes, a cross-sectional study

• Objectives There is currently limited understanding of the relationship between copeptin, the midregional portion of proadrenomedullin (MRproADM) and the midregional fragment of the N-terminal of proatrial natriuretic peptide (MRproANP), and arterial disorders. Toe brachial index (TBI) and aortic pulse wave velocity (aPWV) are established parameters for detecting arterial disorders. This study evaluated whether copeptin, MRproADM, and MRproANP were associated with TBI and aPWV in patients with type 2 diabetes with no history of cardiovascular disease (CVD).Methods In the CARDIPP study, a cross-sectional analysis of 519 patients with type 2 diabetes aged 55–65 years with no history of CVD at baseline, had complete data on copeptin, MRproADM, MRproANP, TBI, and aPWV was performed. Linear regression analysis was used to investigate the associations between conventional CVD risk factors, copeptin, MRproADM, MRproANP, TBI, and aPWV.Results Copeptin was associated with TBI (β–0.0020, CI–0.0035– (–0.0005), p = 0.010) and aPWV (β 0.023, CI 0.002–0.044, p = 0.035). These associations were independent of age, sex, diabetes duration, mean 24-hour ambulatory systolic blood pressure, glycated hemoglobin A1c, total cholesterol, estimated glomerular filtration rate, body mass index, and active smoking.Conclusions Plasma copeptin may be a helpful surrogate for identifying individuals at higher risk for arterial disorders.
