正常人心踝动脉硬化指数与吸烟的相关性：539例分析

Correlation between smoking and cardio-ankle vascular index in 539 normal cases

目的观察吸烟因素与动脉硬化的相关性。方法将539例31-65岁的健康男性分为吸烟组与不吸烟组。采用无创伤肢体动脉硬化检测仪分别检测两组的心踝动脉硬化指数（CAVI）。结果吸烟组CAVI阳性率显著高于不吸烟组（21．7％vs5．3％；P=0．000）。按5岁进行年龄分组，每个年龄段吸烟组CAVI值均高于同年龄段不吸烟组。（P〈0．05）。按每日吸烟量分组，吸烟量大CAVI值偏高，且差异均有统计学意义（P〈0．05）。按年龄分组，烟龄长者CAVI值增高，但差异无统计学意义（P〉0．05）。按吸烟指数分组结果显示，CAVI测量值随吸烟指数的增大而增大。结论CAVI与吸烟具有相关性。

Objective To investigate the association between smoking and coronary atherosclerosis. Methods Totally, 539 healthy male volunteers aged between 31 to 65 years were divided into smoking and non-smoking group and their cardio-ankle vascular index （CAVI） were examined using VaseraVS-1000 vascular screening device. Results CAVI positivity rate was significantly higher in smoking group than in non-smoking group （21.7% vs 5.3%; P = 0.000）. By 5-year age grouping, CAVI values of smoking group were all higher than those of the same age non-smoking group（P 〈 0.05）. When grouping according to daily smoking amount, we found that the larger daily smoking amount was correlated with higher CAVI, and there were significant differences between groups（P 〈 0.05）. When grouping according to the smoking history, CAVI increased in long time smoking group but no significant difference was found（P 〉 0.05）. Grouping according to smoking index, CAVI increased with the smoking index. Conclusion CAVI is correlated with smoking.
