摘要: 目的观察新诊断糖尿病合并H型高血压患者不同部分血管的受损情况。方法选取新诊断2型糖尿病(T2DM)患者379例,根据是否合并H型高血压分为单纯T2DM组159例、T2DM+H型高血压组110例及T2DM+非H型高血压110例。采用超声心动图检测左心室结构,计算左心室质量指数(LVMI);彩色多普勒超声仪检测颈动脉,测量颈动脉内中膜厚度(carotid artery intimamedia thickness, CIMT)或颈动脉粥样硬化斑块形成情况。收集晨尿,计算尿微量白蛋白/肌酐比值(UAlb/UCr),并计算内生肌酐清除率(CCr)。结果①T2DM+H型高血压组和T2DM+非H型高血压组收缩压(SBP)、舒张压(DBP)及同型半胱氨酸(Hcy)水平均较单纯T2DM组升高,高密度脂蛋白胆固醇(HDLC)较单纯T2DM组降低。T2DM+H型高血压组Hcy水平高于T2DM+非H型高血压组,HDLC低于T2DM+非H型高血压组(P<0.05或<0.01);②T2DM+H型高血压组和T2DM+非H型高血压组LVEF<50%、脑损害、颈动脉增厚发生率高于单纯T2DM组,T2DM+H型高血压组左心室肥厚和肾功能损害发生率高于单纯T2DM组(P<0.05或<0.01);③T2DM+H型高血压组和T2DM+非H型高血压组LVMI、UAlb/UCr及CIMT水平均较单纯T2DM组升高,LVEF水平较单纯T2DM组降低(P<0.05或<0.01),T2DM+H型高血压组LVMI、CCr、UAlb/UCr及CIMT水平较T2DM+非H型高血压组升高,LVEF水平较单纯T2DM组降低(P<0.05)。结论糖尿病患者在新诊断时,不同部位的血管即已经存在损伤,合并H型高血压的新诊断糖尿病患者血管损伤更严重。

Abstract: ObjectiveTo observe different vascular injuries  in diabetic patients with Htype hypertension.  MethodsA total of 379 patients with newly diagnosed T2DM were divided into three group according to whether with Htype hypertension: T2DM+Htype hypertension group (n=110), T2DM+nonHtype hypertension group (n=110) and T2DM group (n=159). The left ventricular structure, CIMT or with carotid atherosclerotic plaque formation were tested by ultrasonic cardiogram and color flow Doppler sonography. The LVMI, UAlb/UCr and CCr were counted. Results①The levels of SBP, DBP and Hcy in T2DM+Htype hypertension group and T2DM+nonHtype hypertension group were higher than those in T2DM group, HDLC was lower than that in T2DM group. Hcy level was higher in T2DM+Htype hypertension group than in T2DM+nonHtype hypertension group, and HDLC was significantly lower (P<0.05 or P<0.01); ②Compared with T2DM group, the rates of LVEF<50%, brian damage and IMT in T2DM+Htype hypertension group and T2DM+nonHtype hypertension group were significantly increased (P<0.05 or P<0.01), incidence of LVH and impaired renal function in T2DM+Htype hypertension were significantly increased (P<0.05 or P<0.01). The levels of LVMI, UAlb/UCr and CIMT in T2DM+Htype hypertension group and T2DM+nonHtype hypertension group were significantly higher than those in T2DM group, but the LVEF was significantly lower (P<0.05 or P<0.01), the levels of LVMI, CCr, UAlb/UCr and CIMT were significantly higher in T2DM+Htype hypertension group than those in T2DM+nonHtype hypertension group, and LVEF level was significantly lower (P<0.05).  ConclusionWhen patients are newly diagnosed with diabetes, vascular injury in different parts has formed, and Htype hypertension will aggravate the damage degree.
