中国男性的冠状动脉钙化检测及其意义

目的 :因冠状动脉钙化是冠状动脉粥样硬化的标志之一。故深入研究中国男性冠状动脉钙化的检出率。方法 :共调查 73 8例男性 ,按年龄分成 6组 :<2 9岁、 3 0～ 3 9岁、 40～ 49岁、 5 0～ 5 9岁、 6 0～6 9岁、 >70岁。另按症状分成三个亚组 :冠心病组、无冠心病组、混合组。有不典型胸痛 ,但无证据表明其为典型心绞痛。结果 :男性患者随着年龄增加 ,其冠状动脉钙化检出率显著增加 ;无症状男性 ,随着年龄的增加 ,其冠状动脉钙化的积分增加 ;男女性别间钙化发生率有显著差异。结论 :电子束 CT是有价值的检测冠脉钙化的有用方法 ,中国人男女性别间冠状动脉钙化检出率有显著差异。

Detection of Prevalence of Coronary Artery Calcium in Male in Chinese

Objective: In situ coronary artery calcium is a specific marker for coronary atherome. The study is to investigated the coronary artery calcium in male in Chinese. Methods: Included 738 males in Chinese for electron beam screening, which was divided six groups on age: <29, 30～30, 40～49, 50～59, 60～69, >70 years; and into three subgroup: group with CAD; group without CAD; group with atypical chest pain, but there are insufficient information to judge the chest pain as angina. Results: The prevalence of CAC in male increased significantly with increased age; there is a large increase of score of CAC in asymptomatic male. Conclusion: The noninvasive detection of CAC by EBCT has certain prognostic and predictive value for coronary artery disease and there is a marked difference in the prevalence of coronary artery calcium between male and female.
