80岁及以上高血压患者血压与心脑事件和季节性变化研究
Relationship of seasonal variation of blood pressure with incidences of cardiovascular and cerebrovascular events in patients aged 80 years and over
目的 观察80岁及以上老年高血压患者血压和心脑血管事件的季节性变化. 方法监测67例年龄80~92岁的高血压患者2年间的家庭自测血压、诊室测血压和每季度1次的24 h时动态血压,记录期间发生的心脑血管事件. 结果高血压患者夏季的收缩压、舒张压最低(P<0.01).冬季的收缩压最高(P<0.01),冬季舒张压高于夏季(P<0.01).春季和秋季的收缩压、舒张压差异无统计学意义.心脑血管事件的发病率在夏季和冬季明显高于春季和秋季(P<0.05).发生心血管事件的相关因素为:季节(OR=1.525,P=0.001)、体质指数(OR=1.145,P=0.018)、心功能(OR=2.037,P=0.01),发生缺血性脑血管事件的相关因素为季节(OR=1. 604,P=0.001)、脑血管病史(OR=1.598,P=0.034)、诊室测收缩压(OR=0.960,P=0.013)、动态血压的舒张压(OR=0.936,P=0.008). 结论 80岁及以上老人通过3种方式测得的血压结果显示,夏季的收缩压、舒张压为全年最低;冬季的收缩压全年最高,舒张压高于夏季;春季和秋季的血压水平无明显差异.心脑血管事件的发生率在冬季和夏季明显高于春季和秋季.
更多Objective To investigate the effect of seasonal variation of blood pressure (BP) on the incidence of cardiovascular and cerebrovascular events in the elderly aged 80 years and over.Methods The 67 patients (aged 80-86 years) with essential hypertension were enrolled, the BP were measured at home, in consulting room, and by 24-h ambulatory BP monitor in every season for 2 years. The incidences of cardiovascular and cerebrovascular events were recorded in the meantime.Results Both systolic BP (SBP) and diastolic BP (DBP) were lower in summer than in any other season (P<0. 01 ). SBP was higher in winter than in any other season. (P<0.01), DBP was higher in winter than in summer(P<0. 01). There were no significant differences in SBP and DBP between spring and autumn. The incidence of cardiovascular and cerebrovascular events were higher in winter and summer than in spring and autumn (P<0.05). The season (OR= 1. 525, P=0. 001), BMI (OR =1.145, P=0.018) and heart function (OR= 2. 037, P=0.01) were related to the incidence of cardiovascular events. And the season (OR = 1. 604, P= 0. 001 ), history of cerebrovascular disease (OR= 1. 598, P=0. 034), office-measured SBP (OR=0.960, P=0.013) and ambulatory DBP (OR =0. 936, P = 0. 008) were related to the incidence of cerebrovascular events.Conclusions The blood pressure measured by three methods in the elderly aged 80 and over shows that both SBP and DBP are at the lowest in summer; SBP is at the highest in winter, DBP is higher in winter than in summer. There are no significant differences in BP between spring and autumn. The incidences of cardiovascular and cerebrovascular events are significantly higher in winter and summer than in spring and autumn.
