目的探讨成人冠状动脉起源异常(AOCA)类型及其发生率。方法对2000年10月~2006年10月在我院行冠状动脉造影(1 520例)检出的26例存在AOCA患者资料,以及国内2006年10月以前发表的有关成人AOCA研究的8篇文献资料进行综合分析。结果9组资料冠状动脉造影总例数48 158例,检出AOCA 439例,检出率0.91%。右冠状动脉起源异常发生率0.55%(267例),明显高于左冠状动脉0.36%(174例),差异有统计学意义(P<0.01)。右冠状动脉起源于左冠窦为最常见类型,占41.5%(182例);其次为前降支和回旋支独立开口,占26.0%(114例)。结论我国成人AOCA多见于右冠状动脉,其中具有潜在临床危险的右冠状动脉起源于左冠窦为最常见类型,提示加强国人AOCA研究具有重要临床意义。
Objective To investigate the types of adult coronary artery (AOCA) and its incidence. Methods The data of 26 patients with AOCA detected by coronary angiography (1520 cases) in our hospital from October 2000 to October 2006 were collected, and 8 articles about AOCA in adults published before October 2006 Data for a comprehensive analysis. Results There were 48 158 cases of coronary angiography in 9 groups, and 439 cases of AOCA were detected, the detection rate was 0.91%. The incidence of right coronary artery abnormalities was 0.55% (267 cases), which was significantly higher than that of the left coronary artery (0.36%, 174 cases). The difference was statistically significant (P <0.01). Right coronary artery originated in the left coronary sinus is the most common type, accounting for 41.5% (182 cases); followed by the anterior descending branch and the circumflex artery independent opening, accounting for 26.0% (114 cases). Conclusion AOCA is more common in the right coronary arteries in our country. The most common type of right coronary artery originated from the left coronary artery is potential clinical risk. It suggests that it is of great clinical significance to enhance AOCA in Chinese.
