Abstract：
UNASSIGNED: Coronary artery disease can be quantified by measuring the fat attenuation index (FAI).
UNASSIGNED: To explore the correlations between FAI, high-risk plaque and the degree of coronary artery stenosis.
UNASSIGNED: The clinical data of patients with coronary atherosclerosis who underwent a coronary computed tomography (CT) angiography examination between July 2020 and June 2023 were selected for retrospective analysis. These patients were classified into a high-risk plaque group and non-high-risk plaque group according to the presence of CT high-risk plaque. The diagnostic value of FAI and FAI combined with the degree of stenosis was evaluated for CT high-risk plaque.
UNASSIGNED: Differences in age, body mass index, smoking history, FAI and the degree of stenosis between the two groups were statistically significant (all P< 0.05). The results of a binary logistic regression analysis revealed that FAI (odds ratio (OR): 1.131, 95% confidence interval (CI): 1.101-1.173, P< 0.001) and the degree of stenosis (OR: 1.021, 95% CI: 1.012-1.107, P< 0.001) were risk factors for high-risk plaque.
UNASSIGNED: The FAI can be used to monitor the inflammation level of the coronary artery; the higher the FAI is, the higher the risk of plaque and degree of stenosis.

摘要：
■可以通过测量脂肪衰减指数（FAI）来量化冠状动脉疾病。
■为了探索FAI之间的相关性，高危斑块和冠状动脉狭窄程度。
■选择在2020年7月至2023年6月期间接受冠状动脉计算机断层扫描（CT）血管造影检查的冠状动脉粥样硬化患者的临床资料进行回顾性分析。根据CT高危斑块的存在将这些患者分为高危斑块组和非高危斑块组。评价FAI及FAI结合狭窄程度对CT高危斑块的诊断价值。
■年龄差异，身体质量指数,吸烟史,两组FAI、狭窄程度差异均有统计学意义(均P<0.05)。二元Logistic回归分析结果显示，FAI（比值比（OR）：1.131，95％置信区间（CI）：1.101-1.173，P<0.001）和狭窄程度（OR：1.021，95％CI：1.012-1.107，P<0.001）是高危斑块的危险因素。
■FAI可用于监测冠状动脉的炎症水平；FAI越高，斑块和狭窄程度的风险越高。
