摘　　要：目的:探讨老年原发性高血压患者血压变异性与病情之间的关系。方法:采用无创性全自动血压监测仪对139例老年原发性高血压患者24h动态血压监测,然后计算每例患者血压变异系数并结合临床资料进行统计学分析。结果:老年原发性高血压患者非杓形发生率(69.8%)较杓形者明显增加(χ2=43.53,P<0.01),非杓形者伴随较高的靶器官损害(targetorgandamage,TOD)及脑卒中的发生(67%和33%)(χ2=4.64,P<0.05;χ2=18.00,P<0.01)。TOD和伴随临床情况发生率与24h收缩血压变异系数、24h舒张血压变异系数呈正相关(r=0.220,0.179,P<0.01)。结论:血压变异形态和系数可以作为老年原发性高血压患者病情判断、预后评估的重要参考指标。AIM: To evaluate the relationship between blood pressure variability (BPV) and the state of the illness in aged patients with essential hypertension(EH).METHODS: Noninvasive automatic blood pressure recorder was used to carry out 24 hour ambulatory blood pressure monitoring (ABPM) in 139 aged patients with EH, then blood pressure variable coefficient (BPVC) was calculated and the results were combined with the clinical data for statistical analysis.RESULTS: ①The incidence rate of non ladle type(69.8%) was increased obviously as compared with that of ladle type in aged patients with EH(χ2=43.53,P< 0.01), and the incidence of target organ damage(TOD, 67%) and stroke (33%) in the patients with non ladle type was higher(χ2=4.64, P< 0.05;χ2=18.00, P< 0.01). The TOD and accompany clinical condition (ACC) were positively correlated with the 24 hour systolic and diastolic BPVC(r=0.220, 0.179, P< 0.01).CONCLUSION: It is possible that blood variable shape and BPVC serve as the important reference indices to decide the state of the illness and estimate the prognosis in aged EH patients.
