128层螺旋CT冠状动脉成像冠状动脉斑块成分与性别的关系

目的探讨128层螺旋CT冠状动脉成像冠状动脉斑块成分与性别的关系。方法2012年1月-12月选取行128层螺旋CT冠状动脉成像检查并发现冠状动脉粥样斑块的患者143例，根据年龄分为A组（≤50岁，n=37）和B组（〉50岁，n=106）。结果A组男29例，共发现斑块70处，其中纤维斑块30处，混合斑块17处，软斑块11处，钙化斑块12处；女8例，共发现斑块13处，其中纤维斑块7处，混合斑块2处，软斑块2处，钙化斑块2处；男性与女性间斑块成分构成差异无统计学意义（Х^2=0．664，P〉0．05）。B组男56例，共发现斑块116处，其中混合斑块48处，纤维斑块40处，软斑块及钙化斑块各14处；女50例，共发现斑块90处，其中混合斑块36处，纤维斑块22处，软斑块及钙化斑块16处；男性与女性间斑块成分构成差异无统计学意义（Х^2=3．708，P〉0．05）。结论冠状动脉粥样斑块成分，男性及女性不存在性别优势。

Correlation between Coronary Artery Plaque Composition and the Gender via 128-slice Spiral CT Coronary Artery Imaging

Objective To explore the correlation between coronary artery plaque composition and the gender via 128-slice spiral CT coronary angiography （128-SCTCA）. Methods Between January and December 2012, 143 patients with coronary artery plaque diagnosed by 128-SCTCA were selected. The patients were divided into group A （no more than 50 years old, n=37） and group B （over 50 years old, n=106）. Results There were 29 male patients in group A, with 70 plaques including 30 fibrous plaques, 17 mixed plaques, 11 soft plaques, 12 calcified plaques; and the other 8 female patients had 13 plaques including 7 fibrous plaques, 2 mixed plaques, 2 soft plaques, and 2 calcified plaques. In group B, 56 male patients had 116 plaques, including 48 mixed plaques, 40 fibrous plaques, 14 soft plaques and 14 calcified plaques; the other 50 female patients had 90 plaques, including 36 mixed plaques, 22 fibrous plaques, and 16 soft plaques and calcified plaques. The differences of the plaque composition between males and females were not significant both in group A （Х^2=0.664, P 〉 0.05） and group B （2＂2=3.708, P 〉 0.05）. Conclusion There is no obvious correlation between gender and coronary plaque composition.
