正常人心踝动脉硬化指数与吸烟的相关性: 539例分析

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。

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

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.
