老年高血压患者102例脉压差与相关因素的分析

Pulse pressure difference and its relevant factors in the elderly with hypertension： report of 102 cases

目的了解老年高血压患者的脉压差情况及相关因素。方法于2013年5月～6月入户调查第二军医大学附属长海医院保障的军队离休干部老年高血压患者102例，测量血压、心率、身高、体质量等参数，调查一般情况、生活习惯等相关情况，并使用SPSS19．0进行数据处理与统计分析。结果调查老年高血压病患者102例，年龄78～92岁（84．65±3．14岁），脉压差40～92（62．86±10．01）mmHg，单因素分析示年龄、体质量指数（BMI）、腹型肥胖、高血压病程、高血压危险分层、降压药服用时间均与脉压差相关（P〈0．05），多元逐步回归分析示高血压危险分层、高血压病程、年龄、BMI与脉压差相关（P〈O．001）。结论高血压危险分层、高血压病程、年龄、BMI是老年高血压患者脉压差的主要影响因素。

Objective To describe the profile of pulse pressure difference and its relevant factors in the elderly with hypertensive patients. Methods From May to June 2013, a household survey was carried out for retired military cadres with hypertension who were under the health support system of our hospital. Their blood pressure, heart rate, height and body mass index （BMI） were measured and calculated, and their general information, living styles and other relevant information were collected. The SPSS 19.0 software was used to process and analyze the data. Results Among the 102 elderly hypertensive patients enrolled in this study, their age ranged from 78 to 92 （84.6 ～ 3.14） years, and their pulse pressure difference ranged from 40 to 92 （62.86 ～ 10.01）mmHg. Univariate analysis showed that age, BMI, abdominal obesity, hypertension course, hypertension risk stratification, and duration of taking antihypertensives were significantly correlated with pulse pressure difference （P 〈 0.05）. Multiple stepwise regression analysis indicated that hypertension risk stratification, hypertension course, age and BMI were related to pulse pressure difference （P 〈 0.001）. Conclusion For the elderly hypertensive patients, the hypertension risk stratification, hypertension course, age and BMI are the main impact factors on pulse pressure difference.
