主动脉弓钙化与冠心病不同临床类型的相关性

The Relationships between Calcification of Aortic Arch and Clinical Classification of Coronary Artery Dsease

目的探讨胸部X线片检查发现的主动脉弓钙化与冠心病的不同临床表现类型的相关性。方法回顾分析2006年7月2008年2月期间经冠状动脉造影证实的冠心病患者的临床资料,对比分析胸部平片所见的主动脉弓钙化情况与冠心病不同临床类型的相互关系。结果 116例经冠状动脉造影证实的冠心病患者纳入研究。其中,稳定型心绞痛40例,急性冠脉综合征76例(不稳定型心绞痛21例、非ST段抬高心肌梗死38例、ST段抬高心肌梗死17例)。40例稳定型心绞痛患者中,有主动脉弓钙化者21例,占52.5%;76例急性冠脉综合征患者中,有主动脉弓钙化者22例,占28.9%。与急性冠脉综合征相比,更多的稳定型心绞痛患者合并有主动脉弓钙化(χ2=6.232,P=0.013)。结论在不同的冠心病临床类型,主动脉弓钙化更易在稳定型心绞痛患者中发现。

Objective To investigate the relationships between calcification of aortic arch and different clinical classification of coronary artery disease.Methods The clinical data of patients with coronary artery diease who diagnosed by arteriography from July 2006 to February 2008,were retrospectively analyzed.The X-ray data on calcification of aortic arch and clinical characteristics of patients with coronary artery disease confirmed by coronary angiography were analyzed.The relationship between coronary calcification of aortic arch which showed by X-ray and different clinical classification of coronary artery disease were comparatively analyzed.Results Among the total of 116 patients,40 stable angina and 76 acute coronary syndrome were included,and 21（52.5%）and 22（28.9%）patients with calcification of aortic arch were observed respectively.In comparison to patients with acute coronary syndrome,more stable angina patients were complicated with calcification of aortic arch（χ^2 =6.232,P=0.013）.Conclusion It is more likely to document calcification of aortic arch in patients with stable angina.
