[摘 要] 目的:探讨冠状动脉周围脂肪衰减指数(fat attenuation index,FAI)及斑块定量特征与脑白质高信号(white matter hy⁃
perintensity,WMH)的相关性。方法:回顾性搜集 2021 年 1 月—2022 年 12 月 407 例患者的临床、冠状动脉 CT 血管成像(coro⁃
nary computed tomography angiography,CCTA)及头颅磁共振成像(magnetic resonance imaging,MRI)资料。采用 Fazekas 评分评
估WMH严重程度,并将其分为轻度WMH组(Fazekas评分0~2分)和中重度WMH组(Fazekas评分3~6分),比较两组患者的临
床资料、FAI及斑块定量参数,寻找中重度WMH 的独立影响因素。结果:FAI和斑块定量参数在两组患者间的差异有统计学
意义(P < 0.05)。多因素 Logistic 回归结果显示,年龄(OR=1.116,95%CI:1.074~1.160,P < 0.001)、冠心病(OR=2.737,95%CI:
1.270~6.017,P=0.010)、斑块负荷(OR=4.142,95%CI:1.228~13.977,P=0.022)及 FAI>-70.1 HU(OR= 5.089,95%CI:1.899~
13.640,P=0.001)是中重度WMH的独立影响因素。结论:年龄大、患有冠心病、斑块负荷大、FAI>-70.1 HU的患者更容易发生
中重度WMH,为冠脉粥样硬化和WMH的联合管理提供了理论依据。

[Abstract] Objective:To explore the correlation between the fat attenuation index(FAI)and plaque quantification parameters with
brain white matter hyperintensities(WMH). Methods:A retrospective collection of clinical,coronary computed tomography
angiography(CCTA)and brain magnetic resonance imaging(MRI)data of 407 patients from January 2021 and December 2022 was
conducted. The severity of WMH was assessed using the Fazekas score,dividing patients into mild WMH group(Fazekas score 0⁃2)
and moderate to severe WMH group(Fazekas score 3-6). Clinical data,FAI,and plaque quantification parameters of the two groups
were compared to identify independent risk factors for moderate to severe WMH. Results:There were statistically significant
differences in FAI and plaque quantification parameters between the two groups(P < 0.05). The results of multivariable logistic
regression showed that age(OR=1.116,95%CI:1.074-1.160,P < 0.001),coronary artery disease(OR=2.737,95%CI:1.270-6.017,P=
0.010),plaque burden(OR=4.142,95%CI:1.228-13.977,P=0.022),and FAI >-70.1 HU(OR=5.089,95%CI:1.899-13.640,P=
0.001)were independent influencing factors for moderate to severe WMH. Conclusion:Older age,presence of coronary artery disease,
higher plaque burden,and FAI>-70.1 HU are associated with a higher likelihood of developing moderate to severe WMH,providing a
theoretical basis for the joint management of coronary atherosclerosis and WMH.
