摘　　要：目的探讨收缩压和舒张压水平对高龄老年人死亡率的影响。方法选取2013年4月至6月间80岁以上驻沈地区军队离退休干部年度体检者666例,对其血压及生存状况进行为期43个月的随访。结果666例80岁以上高龄老人中,高血压患者521例,占78. 2%,在43个月随访期间高血压组死亡率21. 9%,非高血压组死亡率13. 8%,两组之间差异有统计学意义(P <0. 05)。高血压组平均血压137/71 mmHg,收缩压(SBP)≥140 mmHg组与SBP <140 mmHg组在死亡率方面差异无统计学意义(P> 0. 05)。高血压组患者根据舒张压(DBP)不同进行分组后发现DBP> 70 mmHg组死亡率为15. 9%,60 mmHg <DBP≤70 mmHg组死亡率为21. 1%,DBP≤60 mmHg组,死亡率高达43. 8%,差异有统计学意义(P <0. 05)。结论高血压明显增加80岁以上高龄老人死亡风险,高龄老年高血压患者更应关注其舒张压水平,尤其是DBP≤60 mmHg的低舒张压的高血压患者,死亡风险明显增高。Objective To investigate the effect of systolic blood pressure and diastolic blood pressure on the mortality in elderly patients over 80 years old. Methods A total of 666 retired military officers aged 80 and over were examined in our hospital from April 2013 to June. They were followed up for 43 months. Results 666 elderly over 80 years old,521 people with hypertension,78.2%. The mortality rate of hypertension group was 21.9% during the 43 month follow-up, and 13.8 % in non hypertensive group. There were significant differences between the two groups （P 〈 0.05 ）. There was no significant difference in mortaliU between hypertension group 137/71 mm Hg and SBP 〉 140 mm Hg group and SBP 〈 140 mm Hg group（P 〉 0.05）. The patients in the hypertension group were grouped according to the DBP difference. The mortality of DBP 〉70 mm Hg group was 15.9% ,the mortality of 60 mm Hg 〈 DBP 〈70 mm Hg group was 21. 1% , DBP 〈 60mm Hg group and the mortality rate was 43.8%. The difference was significant（ P 〈 0.05 ）. Conclusion Hypertension increase significantly the risk of death for older people over 80 years. The diastolic blood pressure level should be paid more attention in elderly hypertensive patients, especially in patients with low dias- tolic pressure of DBP ≤60 mm Hg and the risk of death also is increased significantly.
