老年男性高血压临床特点及与脉压指数的相关性研究

目的：探讨老年男性高血压的临床特点及与脉压指数的相关性。方法：按年龄的不同将男性高血压患者分为中年组（15例）和老年组（16例）,计算脉压指数,并做24小时动态血压和临床特点分析。结果：老年组脉压指数、24小时平均脉压差明显大于中年组（P〈0.01）,中年组24小时平均舒张压、24小时平均动脉压明显大于老年组（P〈0.05或P〈0.01）,中年组及老年组脉压指数与24小时脉压差有相关性（分别为r=0.515、P〈0.05,r=0.501、P〈0.05）,脉压指数≥0.4组靶器官损害明显大于脉压指数〈0.4组（P〈0.01）。结论：老年男性高血压患者以收缩压增高、脉压增大为主,反映老年男性高血压患者血管硬化明显,脉压指数是评价血管硬化的较好指标;对脉压指数≥0.4的患者应尽快平稳降压,使血压达标。

Clinical characteristics of elderly male patients with hypertension and its correlation with pulse pressure index

Objective：To explore the clinical characteristics of elderly male patients with hypertension and its correlation with pulse pressure index. Methods：According to the age, male patients with hypertension were divided into the middle - aged group（ 15 eases） and the elderly group （ 16 cases） ,calculated pulse pressure index, analyzed 24 hours ambulatory blood pressure and clinical characteristics. Results：The elderly group of pulse pressure index and 24 hours average pulse pressure difference was larger than the middle - aged group （ P 〈 0.01 ）, the middle - age group of 24 hour average diastolic blood pressure and mean arterial pressure was significantly greater than the elderly group （ P 〈 0.05 or P 〈 0.01 ）, two groups of pulse pressure index and 24 hours pulse pressure difference were related （r = 0.515, P 〈 0.05;r = 0. 501, P 〈 0.05 ） ,pulse pressure index in 90.4 group of target organ damage was significantly greater than pulse pressure index in 〈 0.4 group （P 〈 0.01 ）. Conclusion：Elderlymale patients with hypertension mainly represents elevated systolic blood pressure, pulse pressure increase, it reflects the vascular sclerosis significantly in elderly hypertensive patients, pulse pressure index is a good indicator of the evaluation of vascular sclerosis;pulse pressure index in patients of ≥0.4 should be smooth step - down the blood pressure.
