目的探讨指端脉搏波分析技术检测动脉顺应性的可行性。方法2004年9至10月,采用整群抽样方法,抽取415例成人(农村195人、城市220人,男132人、女283人),平均年龄(47.23±13.85)岁,用Pu lsetrace指端脉搏波测量仪测定动脉硬化指数,重复测量3次,取平均值。结果每例样本的3次硬化指数检测波动范围在4.65%以内(s=0.050),重复检测结果的相关系数达到0.937,与大动脉脉搏波传导速度的相关性为0.629。城乡、男女之间硬化指数的差异无统计学意义。硬化指数与收缩压和年龄的相关性最好,二者的决定系数达到0.613。20~29岁、30~39岁、40~49岁、50~59岁和≥60岁组的硬化指数均值分别为7.35、8.84、10.41、10.95和12.01 m/s,组间差异有统计学意义。结论收缩压和年龄是动脉顺应性的主要影响因素。指端脉搏波分析技术在流行病学研究中具有较好的可行性和推广使用价值。
Objective To explore the feasibility of using finger-tip pulse wave analysis to detect arterial compliance. METHODS: From September to October 2004, 415 adults (195 rural residents, 220 urban residents, 132 males and 283 females) were sampled by cluster sampling with a mean age of 47.23 ± 13.85 years old. Pulse wave measuring instrument for measuring arteriosclerosis index, repeated measurements 3 times, take the average. Results The detection range of the three sclerosis indices in each sample was within 4.65% (s = 0.050), the correlation coefficient of the repeated test results was 0.937, and the correlation with the aortic pulse wave velocity was 0.629. The difference of sclerosis index between urban and rural areas and between men and women was not statistically significant. Sclerotic index and systolic blood pressure and age of the correlation between the best, the two coefficient of determination of 0.613.20 to 29 years old, 30 to 39 years old, 40 to 49 years old, 50 to 59 years old and ≥ 60 years old group sclerosis index mean Were 7.35,8.84,10.41,10.95 and 12.01 m / s, the difference between the groups was statistically significant. Conclusion Systolic blood pressure and age are the main influencing factors of arterial compliance. Fingertip pulse wave analysis technology in epidemiological studies has a good feasibility and promote the use of value.
