目的探讨男性中老年人群短时间内血压变化情况及临床意义。方法对门诊656例测量血压的男性中老年人采用调查形式在5 m in内测量3次,作有关分析。结果中年组BP平均143.9/84.3 mm Hg;老年组BP平均146.0/76.9 mm Hg;第3次比第1次SBP下降人数占64.6%,升高占22.7%,总的变化率为87.3%;DBP下降占52.0%,升高占17.2%,总的变化率为69.2%。SBP、DBP的数值波动最高分别为38、30 mm Hg,5 m in内SBP及DBP变化以下降为主;中老年组SBP及老年组DBP平均压差均大于5 mm Hg。中年、老年人群DBP持平率对比(t=3.544,P<0.001)和DBP升高变化率对比(t=2.550,P<0.05),差异有统计学意义。压差>5 mm Hg的中年组与老年组DBP升高率相比(t=2.208,P<0.05)和DBP下降率相比(t=2.702,P<0.01),差异有统计学意义。结论中老年男性短时间内自身调节血压的功能存在着一定变化空间,中年人群血管舒张收缩变化空间较大,是给予药物康复时须考虑的因素。
Objective To investigate the short-term changes of blood pressure and its clinical significance in middle-aged and elderly men. Methods A total of 656 middle-aged and elderly people who measured blood pressure in the outpatient department were surveyed 3 times within 5 mins of the questionnaire for the analysis. Results The median BP was 143.9 / 84.3 mm Hg in the middle-aged group, BP was 146.0 / 76.9 mm Hg in the elderly group, 64.6% was the third SBP decrease and 22.7% higher than the first SBP. The total change rate was 87.3%. DBP decreased 52.0%, increased 17.2%, the overall rate of change was 69.2%. SBP and DBP had the highest values of 38 and 30 mm Hg, respectively. The changes of SBP and DBP within 5 mins were mainly in the decline. The average pressure difference of SBP and DBP in the middle-aged and elderly patients was more than 5 mm Hg. Compared with the rate of change of DBP (t = 2.550, P <0.05), the difference of DBP between middle age group and elderly group was statistically significant (t = 3.544, P <0.001). The difference in DBP increase rate (t = 2.208, P <0.05) and DBP decrease rate (t = 2.702, P <0.01) in the middle-aged group with pressure difference> 5 mm Hg was statistically significant. Conclusions Middle-aged and old men have a certain space for self-regulation of blood pressure within a short period of time. Middle-aged people have ample space for vasodilation and contraction, which is a factor that must be considered when giving drugs rehabilitation.
