吸烟与颈动脉粥样硬化的相关性

Correlation between smoking and carotid arteriosclerosis

目的探讨吸烟与颈动脉粥样硬化之间的关系。方法以我院体检中心体检者为研究对象，根据吸烟指数分为不吸烟、少量吸烟、中等量吸烟、大量吸烟4组，均进行颈动脉彩色多普勒超声检查，将观察所得数据进行经数据统计处理。结果颈动脉粥样硬化程度随吸烟指数的增加而加重（X^2=24.953，P=0．015）。颈动脉粥样硬化的严重程度与吸烟量及吸烟年限呈正相关（r=0．249，P〈0．01）。结论充分认识吸烟的危害性，将戒烟作为脑卒中尤其是脑梗死的预防措施之一。

Objective To explore the relationship between smoking and carotid Arteriosclerosis. Methods Smokers in the outpatients for medical examination in our hospital were selected as study subjects who were divide into four groups by smoking index：non-smokers,slight smoking group, moderate smoking group and heavy smoking group. All patients were tested with carotid arteriosclerosis via colour doppler uhrasonography. The statistical method was used to analyse data and get to conclusion（ X^2 = 24. 953 ,P = 0. 015 ）. The severity of carotid arteriosclerosis was positively correlated with smoking duration and pack（ r = 0.249 ,P 〈0.01）. Results The degrees of carotid arteriosclerosis became more severe with increase of the smoking index. Conclusion Smoking is harmful sotoquitsmoking should be one of the preventive measures of cerebral stroke especially cerebral infareeion.
