551例中老年女性5分钟内多次测血压结果的分析

Analysis on Result of Reiterative Measuring Blood Pressure in Five Minutes for 551 Cases of Female Midlife and Old Folks

目的探讨女性中老年人短时间内血压变化的情况及临床意义。方法对551例门诊测量血压的女性中老年人,采用调查形式在5 min内测量3次,作有关分析。结果中年组平均BP 141.6/79.5 mm Hg;老年组平均BP143.6/75.4 mm Hg。第3次比第1次SBP下降人数占68.0%,升高占25.4%,总变化率为93.4%;DBP下降占58.8%,升高占19.1%,总变化率为77.9%。SBP、DBP波动值最高为22 mm Hg,5 min内SBP及DBP变化以下降为主;中老年组SBP及老年组DBP平均压差均大于5 mm Hg。中年、老年平均压差及SBP、DBP升高下降变化率差异无统计学意义(P>0.05)。压差>5 mm Hg中年高血压组与老年非高血压组的SBP下降率对比差异有统计学意义(t=2.094,P<0.05)。结论在SBP、DBP压差升高>5 mm Hg的人群,中老年女性短时间内自身调节血压的功能存在着一定变化空间,是给予药物康复时须考虑的因素。

Objective To explore the blood pressure change in short time and the clinic meaning in female midlife and old folks. Methods The blood pressure of 551 outpatients of female midlife and old folks was measured three-time in five minutes.

SBP and DBP wave cost tiptop was 22 mm Hg. SBP and DBP change gave priority to drop in five minute. The average pressure difference of SBP in midlife and old folks group and DBP in old folks group all exceeded 5 mm Hg. There was no significantly difference in the average pressure difference and change rate between the midlife group and old folks group （ P 〉 0.05 ）. The difference was obviously in SBP decrease scale between the hypertension midlife group and non-hypertension old folks group with the 5 mm Hg pressure difference （ P 〈 0.05 ）.
