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 correlation between aortic arch calcification and different clinical manifestations of coronary heart disease found on chest radiography. Methods The clinical data of patients with coronary heart disease confirmed by coronary angiography between July 2006 and February 2008 were analyzed retrospectively. The relationship between aortic arch calcification and different clinical types of coronary heart disease was analyzed. Results One hundred and sixteen patients with coronary heart disease confirmed by coronary angiography were included in the study. Among them, 40 cases had stable angina pectoris, 76 cases had acute coronary syndrome (unstable angina pectoris 21 cases, 38 cases with non-ST elevation myocardial infarction and 17 cases ST-segment elevation myocardial infarction). Forty patients with stable angina pectoris had 21 cases of aortic arch calcification, accounting for 52.5%. Among 76 patients with acute coronary syndrome, 22 cases had aortic arch calcification, accounting for 28.9%. Comparing with acute coronary syndrome, more patients with stable angina complicated with aortic arch calcification (χ2 = 6.232, P = 0.013). Conclusion In different clinical types of coronary heart disease, aortic arch calcification is more likely to be found in patients with stable angina.
