肾小叶间动脉阻力指数变化在高血压患者中的临床意义

摘要

Objective:To investigate the changes of renal interlobular arterial resistive index (RI) in patients with primary hypertension,and research what renal arterial RI means at patients with hypertension.Methods:115 cases of primary hypertensive patients were selected.Renal arterial RI were detected in all cases by Color Doppler Flow Imaging.Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured on the same day of examination.Pulse pressure (PP),Mean pressure(MBP) was calculated.Blood urea nitrogen (BUN),serum creatinine (Scr) etc were measured in all Patients.Results:Renal interlobular arterial RI in hypertension patients showed that renal arterial RI positively correlated with Hypertension time,SBP,PP,age Ccr and negative correlated with DBP.No correlated with MBP BUM and Scr.Conclusion:Primary hypertensive patient's renal interlobular arterial RI correlated with Hypertension time,SBP DBP PP AGE Ccr,Renal interlobular arterial RI can reflect the state of arteriosclerosis in the body.%目的:分析原发性高血压患者小叶间肾动脉阻力指数(resistive index,RI)与临床指标的相关性,研究肾动脉阻力指数对高血压患者临床意义.方法:选择原发性高血压患者115例.用彩色多普勒超声仪测量肾小叶间动脉的RI,彩超检查的当天测量收缩压(SBP)和舒张压(DBP),计算脉压(PP)、平均血压(MBP);检测血清尿素氮(BUN)、血清肌酐(Scr)、血清尿酸(UA),估算内生肌酐清除率(Ccr);分析小叶间肾动脉RI与临床指标的相关性.结果:高血压患者小叶间肾动脉RI与Ccr、SBP、DBP、PP、年龄、高血压发病时间均有相关性.高血压分级、平均血压、BUN、Scr、UA与小叶间肾动脉RI无相关性.结论:原发性高血压患者的小叶间肾动脉RI与Ccr、SBP、DBP、PP、年龄、高血压发病时间相关,可以间接反映高血压对肾动脉的影响及全身动脉硬化的状况.
