【摘要】 目的：观察肾性高血压与原发性高血压患者动态血压情况及节律变化。方法：采用美国无创性便携式动态血压监测仪，测试时间８～９ Ａｍ 至次日８～９ Ａｍ，测量间隔为３０ ｍｉｎ。结果：两组患者的２４ ｈ ＳＢＰ、２４ ｈ ＤＢＰ、ｄ ＳＢＰ、ｄ ＤＢＰ及血压负荷无明显差异（ Ｐ＞ ０．０５）。肾性高血压组ｎ ＳＢＰ、ｎ ＤＢＰ显著高于原发性高血压组（Ｐ＜ ０．００１），原发性高血压组夜间ｎ ＳＢＰ、ｎ ＤＢＰ均低于白昼血压（ Ｐ值均＜ ０．０１），肾性高血压组的夜间ｎ ＳＢＰ、ｎＤＢＰ与白昼血压无明显差异（Ｐ＞ ０．０５）。肾性高血压组ＳＢＰ、ＤＢＰ夜间下降百分率＜１０％ 者，明显高于原发性高血压组（分别为４８％ 、６０％ 及３０％ 、２２．５％ ，Ｐ＜ ０．０５） 。结论：原发性高血压患者的动态血压存在着昼夜节律，肾性高血压患者节律性消失。更多还原

【Abstract】 Observe the BP condition and the rhythm change of renal hypertension patient and essential hypertension patient.Methods:By taking no-wounded ambulatory BP monitoring.The testing time is from 8～9 Am.The testing interval is 30 minutes.Results:From the value of the 24 h SBP ,the d SBP and Bp load there is no distinct difference between the two groups(P>0.05).The ralue of n and n DBP among the renal hypertension patient is greatly higher than that of the essential hypertension group(P均<0.001).Among the essential hypertension patient group the value of n SBP and n DBP are both lower than of the daytime(P均<0.01).Among the renal hypertension patients the n SBP and n DBP has no difference from that of the daytime(P均>0.05).The number of the renal hypertension patients whose decreasing percent of SBP and DBP during the night time is less than 10% is greatly higher than that of the essential hypertension patient group (each value is 48%,60%and 30% 22.5%,P<0.05).Conclusion :The ambulatory BP of essential hypertension patient has its diumal and nocturnal rhythm,that is the nocturnal BP is lower than diumal BP and this rhythm disappears among the renal hypertesion pationt is in high level in most time of a day.更多还原
