摘    要:目的:评价高血压合并颈动脉斑块患者的内皮功能的变化并探讨可能的影响因素。方法选取2011年1月至2012年1月在我院就诊的高血压合并颈动脉斑块患者71例,同期选取来我院体检的健康者20例作为正常对照组。以血流介导的内皮依赖性血管舒张功能( FMD)和硝酸甘油引起的非内皮依赖性血管舒张功能(NMD)作为内皮功能的检测指标。另外检测入选人群的内中膜厚度(IMT)、尿微量白蛋白、血清肌肝(Cr)、尿酸(UA)、血糖(Glu)、血脂、超敏C反应蛋白(hs-CRP)等生化指标,并计算尿白蛋白排泄率( UAER )、内生肌酐清除率( Ccr )。结果(1)两组间 FMD、NMD、IMT、收缩压( SBP )、舒张压(DBP)、Cr、UA、Glu、总胆固醇(TC)、低密度脂蛋白(LDL)、hs-CRP、UAER的对数(LgUAER)差异均有统计学意义( P<0.05)。(2)△FMD%与 SBP ( r =-0.442, P =0.000)、IMT ( r =-0.217, P =0.040)、Glu ( r =-0.356,P=0.001)、TC ( r=-0.381, P=0.000)、LDL ( r=-0.267, P=0.011)、hs-CRP ( r=-0.234, P=0.026)、LgUAER(r=-0.596,P =0.000)呈负相关;△NMD%与年龄(r =-0.207,P =0.049)、SBP(r =-0.271,P=0.009)、IMT(r=-0.296,P=0.004)、Glu(r=-0.220,P=0.036)、LgUAER(r=-0.311,P=0.003)呈负相关。(3)多元线性回归分析 FMD 的主要危险因素是 UAER、TC (调整的 R2=0.329, P =0.027);NMD的主要危险因素是UAER、年龄(调整的R2=0.076,P=0.044)。结论高血压合并颈动脉斑块患者的内皮功能减低,UAER、TC、年龄是其内皮功能障碍的主要危险因素。

Abstract:Objective To evaluate the changes of endothelial function in patients with hypertension and carotid plaques ,and to investigate its influencing factors .Methods This study included 71 hypertensive patients with carotid plaques and 20 healthy people as normal control in our hospital from 2011 to 2012 .Endothelial function was assessed by flow-mediated dilation ( FMD) and nitroglycerin-mediated dilation ( NMD) in the brachial artery by ultrasonography.At mean time, the intima-media thickness ( IMT), microalbuminuria, creatinine ( Cr), uric acid ( UA) , glucose ( Glu ) , blood lipid and hypersensitive C reactive protein ( hs-CRP ) were evaluated .The urinary albumin excretion rates ( UAER) and the creatinine clearance rate ( Ccr ) were calculated .Results ( 1 ) There were significant differences between the two groups in the FMD ,NMD,IMT,systolic blood pressure(SBP),diastolic blood pressure(DBP),Cr,UA,Glu,total cholesterol(TC),low density lipoprotein(LDL),hs-CRP,LgUAER(P<0.05). (2)The△FMD% showed a negative correlation with SBP (r =-0.442,P =0.000),IMT(r =-0.217,P =0.040),Glu(r=-0.356,P=0.001),TC(r=-0.381,P=0.000),LDL(r=-0.267,P=0.011),hs-CRP(r=-0.234 ,P=0.026 ) and LgUAER ( r=-0.596 ,P=0.000 ).The△NMD%showed a negative correlation with age (r=-0.207,P=0.049),SBP(r=-0.271,P=0.009),IMT(r=-0.296,P=0.004),Glu(r=-0.220,P=0.036) and LgUAER(r=-0.311,P=0.003).(3)Multiple regression analysis showed that UAER and TC were the independent determinants of the FMD (adjusted R2 =0.329,P=0.027),and that UAER and the age were the independent determinants of the NMD(adjusted R2 =0.076,P=0.044).Conclusion The endothelial function is impaired in the hypertensive patients with carotid plaques .The UAER,TC and age are the main risk factors of the endothelial function .
