【摘要】 目的 :探讨老年高血压病患者血压变异性与靶器官损害及年龄的关系。方法 :对 478例老年高血压病人及 2 2 9例非高血压者进行了 2 4小时动态血压监测 ,以测得的血压标准差作为血压变异性指标。结果 :高血压病患者的 2 4小时血压变异性大于非高血压者 (P<0 .0 5 ) ;高血压病人中靶器官损害者的 2 4小时血压变异性大于无损害者的 (P<0 .0 5 ) ;各年龄组间的血压变异性无明显差别。结论 :老年高血压病人 2 4小时血压变异性增加 ,靶器官损害者的 2 4小时血压变异性更高。更多还原

【Abstract】 Objective:To investigate the relationship among blood pressure variability(BPV) and target organ damage,age in elderly hypertensive patients.Methods:Four hundred and seventy-eight elderly hypertensive patients and 229 non-hypertensive patients were undergone 24 hours ambulatory blood pressure monitoring(ABPM). The BPV was determined by standard deviation from mean blood pressure during 24 hours.Results:BPV in elderly hypertensive patients was higher than that in non-hypertensive patients( P <0.05).BPV in hypertensive patients with target organ damage was higher than that in those without target organ damage( P <0.05).There was no significant difference in BPV among three age groups in both hypertensive and non-hypertensive patients.Conclusion:BPV of elderly patients with hypertensiveis increscent.The BPV of hypertensive patients with target organ damage is higher.更多还原
