摘要
目的观察中老年高血压患者夜间收缩血压异常下降的杓类型和脉压指数对靶器官损伤的影响。方法动态血压监测158例,以夜间收缩压下降不同幅度分为极度杓型(ED)、杓型(D)、非杓型(ND)和逆杓型(RD)4组;以24 h平均脉压计算脉压指数(PPI),并以脉压指数≥0.40为基数。结果 4组杓类型中ED 4例,D 42例,ND 77例,RD 35例;4组脑损伤发生率依次为ED>RD>ND>D;心肌肥厚和冠心病的发生率RD较他组高。PPI≥0.40者77例TOD远较<0.39值81例者高(P<0.01),RD组PPI≥0.40者24例,TOD20例,发生率91.67%。结论 ABPM RD患者PPI≥0.40是TOD的重要指标。
Objective To study clinical effect of the nocturnal systolic Blood Pressure Fall pattern and pulse pressure index on targeted organ damage in elderly patients with hypertension.Methods The 24-hour ambulatory blood pressure was monitored for the 158 cases of elderly patients with hypertension.All patients were divided into 4 groups by their nocturnal systolic Blood pressure Fall ED,D,ND,RD.24-hour pulse pressure was also used to measure pulse pressure index（PPI,the base of PPI is ≥0.04）.Results The number of the dipper pattern in four groups were 4,42,77and 35,respectivelly.The occurrence rate of the cerebral damage from high to low were ED,RD,ND and D.The rate of left ventricular hypertrophy and CHD in RD group was higher than other groups.The occurrence rate of TOD was significantly higher in 77 cases of PPI ≥0.40 than 81 cases of PPI0.39（P0.01）.24 cases of PPI≥0.40 and 20 cases cured TOD in RD groups,the occurrence rate was 91.67%.Conclusion ABPM PPI≥0.40 has a satisfactory value for predicting the incidence of TOD in patients with RD.
