蒙古族与汉族冠状动脉钙化斑块分布与积分比较

The comparison of the distribution and score of calcification of coronary artery between mongolian and han population

目的分析蒙古族与汉族冠状动脉钙化斑块分布与积分的异同。方法收集242例蒙古族和488例汉族冠心病患者行冠状动脉钙化积分检查的资料，分析二者冠状动脉钙化的分布及钙化积分情况，对二者结果行统计学分析比较。结果蒙古族与汉族冠状动脉钙化的分布均以前降支为主。蒙古族双支病变的发生率较汉族高（P〈O．05）。两个民族相比，相同性别钙化积分方面比较差异无统计学意义（P〉O．05）。60～69岁、≥70岁年龄段患者的LAD的钙化积分有统计学意义（P〈O．05）。结论蒙古族双支病变相对多，老年组钙化积分高于汉族。

Objective To analyze the difference of the distribution and score of coronary arterial calcification between Mongolian and Han population. Methods The clinical data of 242 Mongolian population and 488 Han population with cor onary heart disease, who had calcification score, were included in the study and were evaluated. Results The prevalence of calcification was observed in LAD, double coronary arterial lesions were found higher in Mongolian population （ P 〈 0.05）. No statistical difference of the score of the coronary arterial calcification was found between the two groups with homogeneity （ P 〉0.05）. The score of the coronary arterial calcification of LAD was higher in Mongolian population than that in Hans （aged 60～69 years or ≥70 years）. Conclusion Double coronary arterial lesions are dominant in Mongolian population,the score of the coronary arterial calcification is higher than that in Han in the old age.
