236例老年人,C组50例,HT组90例,DM组96例,DM-A组40例,DM-B组56例,其中诊室血压漏诊11例(19.6%);使用TM-2421动态血压仪(A&D)监测记录24小时ABP。结果:C与HT组的大多数ABP昼夜变化呈“勺型”模式,DM-A和DM-B组则多数为“浅勺型”模式,反勺型比率明显增加,其中SBP反勺型比率比C组显著增加(P<0.05);HT组的反勺型比率与C组比较也有增加,但无统计学显著差异(P(0.05)。DM-A组夜间PP均值明显高于对照组(P<0.05);DM-B组全部ABP参数均明显高于C和DM-A组(P<0.01),并且,DBP均值(24小时、白天)、白天DBP负荷明显低于HT组(P<0.01或0.05)。HT组全部ABP参数均明显高于C和DM-A组(P<0.01)。结论:老年糖尿病患者ABP昼夜变化模式发生明显改变,并且在合并高血压之前部分夜间ABP指标已出现明显异常。
236 patients were elderly, 50 patients in group C, 90 patients in HT group, 96 patients in DM group, 40 patients in DM-A group and 56 patients in DM-B group. Among them, 11 patients (19.6% Blood Pressure Monitor (A & D) Monitor records 24-hour ABP. Results: The diurnal changes of most ABP in C and HT groups showed a pattern of “spoon”, while in DM-A and DM-B groups, most of them were in “shallow spoon” pattern, (P <0.05), while the reverse scooping ratio in HT group also increased compared with C group, but there was no significant difference (P (0.05)). The average PP value of night in DM-A group was significantly higher than that in C group (P <0.05). All ABP parameters in DM-B group were significantly higher than those in C and DM-A groups (P <0.01). DBP mean (24 hours, daytime) (P <0.01 or 0.05) .All ABP parameters in the HT group were significantly higher than those in the C and DM-A groups (P <0.01) .Conclusion: The diurnal pattern of ABP in elderly patients with diabetes mellitus was significantly changed, Nighttime ABP indicators have shown significant abnormalities.
