摘　　要：目的:比较肱动脉袖带血压与中心动脉血压的差异性,并探讨两者间差异的可能影响因素及机制。方法:选择住院行诊断性冠脉造影患者128例,平均(60.87±9.36)岁。术前测量脉搏波传导速度(PWV),容量顺应性(C1),振荡顺应性(C2),术中记录升主动脉压力(中心动脉血压,CAP),并同步测量肱动脉袖带血压。结果:(1)根据中心动脉与肱动脉袖带收缩压(SBP)差异程度分为3组:相符组(两者相差≤4mmHg)21例(16.40%),高估组(后者高于前者,差值>4mmHg)14例(10.94%),低估组(后者低于前者,差值>4mm-Hg)93例(72.66%);(2)低估组人群传统心血管危险因素多,多为老年,高血压、冠心病较多(P<0.05);(3)低估组PWV明显增快(P<0.05);(4)低估组C2明显降低(P<0.05)。结论:中老年人肱动脉袖带血压大多数低于中心动脉压,中心动脉硬化可能与之有关。Objective： To analyze the differences between brachial artery pressure and central aortic pressure, and to investigate the factors and possible mechanisms of brachial blood pressure overestimate or underestimate central aortic pressure. Methods.. A total of 128 patients [aged （60. 87±9. 36）] were enrolled. Central aortic pressure was invasively determined by catheterization and brachial artery pressure was non-invasively determined by sphygmomanometer simultaneously. The volume compliance （C1） and shock compliance （C2） were detected by HDI CV Profilor DO- 2020 and pulse wave velocity （PWV） was detected by BP--203RPEII （VP--1000）. Results： （1） The patients with SBP of brachial systolic blood pressure agree to central aortic pressure （difference≤4 mmHg） were 21 cases （16.40 %）, brachial systolic blood pressure overestimates central aortic pressure SBP （difference〉4mmHg） were 14 cases （10. 94%）, brachial systolic blood pressure underestimates central aortic pressure （ difference〉4 mmHg） were 93 cases （72.66%）; （2） Patients in underestimated group had more traditional cardiovascular risk factors： elderly , hypertension and coronary heart disease, etc. （P〈0.05） ; （3） PWV was faster in underestimated group （P〈0. 05） ; （4） C2 was lower in underestimated group （P〈0. 05）. Conclusion： （1） The majority patients are with braehial systolic blood pressure underestimates central aortic pressure in middle aged and aged patients; （2） Aortic arteriosclerosis are correlated with peripheral SBP underestimates central SBP.
