老年人体位性血压变化与动脉粥样硬化的关系分析

Analysis on the Relationship between Postural Blood Pressure and Atherosclerosis in the Elderly

目的研究老年人体位性血压变化与动脉粥样硬化的关系。方法按照随机分配的原则,抽取2017年1—12月在郑州人民医院治疗的99例老年患者,按照体位性血压变化情况进行分组:A组52例,正常;B组29例,体位性低血压;C组18例,体位性高血压。99例患者均进行四肢血流多普勒超声检测。分析A组、B组和C组患者体位性血压变化与动脉粥样硬化指标踝臂指数(ABI)、肱踝脉搏波传导速度(baPWV)的关系。结果相较于A组,B组两侧ABI值明显降低(P<0.05);A组、B组和C组两侧baPWV比较,差异无统计学意义(P>0.05);相较于B组,C组ABI低值比例较低(P<0.05)。结论动脉粥样硬化是老年人体性位低血压发生的危险因素之一,ABI低值与体位性低血压发生具有一定的相关性,但与体位性高血压则无明显相关性。

OBJECTIVE To study the relationship between postural blood pressure and atherosclerosis in the elderly. METHODS According to the principle of random distribution, 99 elderly patients treated in target hospital from January 2017 to December 2017 were selected. According to the changes of postural blood pressure, 52 cases in group A were normal;29 cases in group B were postural hypotension;18 cases in group C were postural hypertension. The relationship between postural blood pressure changes and atherosclerosis index, ankle-brachial index( ABI)and brachial-ankle pulse wave velocity(baPWV)was analyzed in group A, group B and group C. RESULTS Compared with group A, the ABI values on both sides of group B were significantly lower(P<0.05). There was no significant difference in baPWV between groups A, B and C(P>0.05). Compared with group B, the proportion of low ABI in group C was lower(P<0.05). CONCLUSION Atherosclerosis was one of the risk factors of postural hypotension in the elderly. The low ABI value was correlated with postural hypotension, but not with postural hypertension.
