摘　　要：目的探讨CT脂肪衰减指数(FAI)应用于冠状动脉不同分支的影响因素。方法回顾性选取冠状动脉病变并进行CT血管成像(CTA)的患者48例,将冠状动脉不同分支根据有无斑块分组,采用SPSS统计学软件进行差异性分析。最终将左前降支(LAD)、左回旋支(LCX)和右冠状动脉(RCA)FAI值可能的影响因素[年龄、性别、体质量指数(BMI)、吸烟史、糖尿病史、高血脂、高血压]进行多元线性回归分析。结果当冠状动脉斑块存在时,FAI值在LAD有显著差异性(P<0.05),而在LCX、RCA无统计学差异。同时,BMI为冠心病患者LAD FAI值的影响因素(P<0.05)。结论FAI应用于冠心病患者时,应考虑斑块、BMI对LAD FAI值的影响。Objective To investigate the influence factors of CT fat attenuation index(FAI)applied to different coronary artery branches.Methods Forty-eight patients with coronary artery lesions who underwent computed tomography angiography(CTA)were retrospectively selected,and the different branches of coronary artery were grouped according to the presence or absence of plaque.SPSS statistical software was performed to difference analysis.The possible influence factors[age,gender,body mass index(BMI),history of smoking,history of diabetes,hyperlipidemia,hypertension]on the FAI values of the left anterior descending artery(LAD),left circumflex artery(LCX),and right coronary artery(RCA)were finally analyzed in a multivariate linear regression analysis.Results When coronary plaque was present,there was significantly different in FAI value of LAD(P<0.05),while there was no statistically significant difference in LCX and RCA.Meanwhile,BMI was an influential factor in the LAD FAI values in patients with coronary heart disease(P<0.05).Conclusion When FAI is applied to patients with coronary heart disease,the effect of plaque and BMI on the LAD FAI value should be considered.
