ABSTRACT
Purpose To explore the application of vascular echo tracking technology in early stage vascular lesions of type 2 diabetes mellitus combined with proteinuria with normal intima and medial membrane of femoral artery,in order to provide evidence for early clinical intervention and to reduce complications of diabetes patients.Materials and Methods Fifty-two patients with type 2 diabetes mellitus diagnosed in Longgang Central Hospital from March 2015 to July 2016 were selected,20in proteinuria group and 32 in group without proteinuria.30 patients at the same stage with normal physical examination results were selected as control group.Vascular echo-tracking technology was used to check femoral arterial elasticity on both sides of the examinee,including stiffness parameter (β),pressure-strain elasticity modulus (Ep),arterial compliance (AC),augmentation index (AI) and one-point pulse wave velocity (PWVβ).Results ① Ep,β and PWVβ of femoral artery in diabetes patients were higher than those in control group,and AC was lower than that in control group.The differences was of statistical significance (P＜0.05).There was no statistical difference in AI between the two groups (P＞0.05).② Ep,β and PWVβ of femoral artery for patients in proteinuria group were higher than those in group without proteinuria and AC was also lower.The difference was of statistical significance (P＜0.05).There was no statistical difference in AI between the two groups (P＞0.05).③ After judgment and analysis,AC and diastolic blood pressure were of statistical significance for judgment,and sensitivity was 92.3％ and specificity 100.0％ when adopting its function to diagnose diabetes femoral arterial elasticity.Conclusion Vascular echo-tracking technology can accurately assess femoral elasticity for diabetes patients and is of great significance in early preventive treatment of diseases.The appearance ofproteinuria indicates that vascular elasticity function decreases dramatically.
