老年人群臂间血压差异研究

The detection of inter-arm blood pressure difference of elderly people

目的探讨老年人群臂间血压差异（IAD）范围及其异常构成比发生情况。方法随机选取于本院门诊及健康体检中心就诊者1566例,采用双臂同步自动血压测量仪（欧姆龙HEM-7220型）记录血压数值并计算IAD,包括臂间收缩压差异（s IAD）、臂间舒张压差异（d IAD）。分别按照年龄（〈60岁、60~80岁,〉80岁）及IAD水平（IAD≤5 mm Hg、5 mm Hg10 mm Hg）分组,比较不同人群异常IAD构成比。结果 1 5 mm Hg10 mm Hg：〉80岁组d IAD构成比高达12.3%。2不同性别异常IAD构成比中s IAD比较差异无显著性,而d IAD则以女性增高较为明显。3 5 mm Hg10 mm Hg：d IAD构成比仍以有高血压者为高。结论老年人群存在较高的IAD异常构成比,在女性、高血压人群异常d IAD构成比也较高,临床工作中应引起高度重视。

Objective To provide baseline data of the inter-arm blood pressure difference（IAD） among elderly people. Method 1566 cases who visited the outpatient clinic and inpatient department of our hospital were examined. Simultaneous BP measurements were obtained used the Omron HEM-7220 BP monitor in both arms. Three BP recordings were obtained in each arm and then IAD was calculated. IAD included s IAD（systolic inter-arm difference） and d IAD（diastolic inter-arm difference）. The constituent ratios were compared between subjects who were divided into groups of age（ 60 years, 60 ~ 80 years, 80 years） and IAD ≤ 5 mm Hg、5 ~ 10 mm Hg and 10 mm Hg. Result 1 The constituent ratios of IAD 5 ~ 10 mm Hg and 10 mm Hg in older cases were higher mainly reflected in d IAD. 2 Of IAD 5 ~ 10 mm Hg and 10 mm Hg in femal the constituent ratios were higher（20.1%, 4.8% respectively） in d IAD compared with those of male（16.9%, 2.0% respectively）. 3 Participants with hypertensives had a higher constituent ratios of d IAD compared with those of normotensives. Conclusion There are considerable differences in inter-arm diastolic blood pressure associated with femal or hypertension and so emphasizes concerning to its importance of clinically significant.
