目的
2
探究冠状动脉周围脂肪衰减指数(fat attenuation index,FAI)和纤维斑块指数(fibrous plaque index,FPI)对急性冠状动脉综合征(acute coronary syndrome, ACS)患者预后的预测价值。
方法
2
采用回顾性队列研究设计,纳入于2021年3月至2023年7月在陆军军医大学第一附属医院心内科及重庆医科大学附属永川医院心内科接受冠状动脉介入治疗(percutaneous coronary intervention,PCI)的334例ACS患者,所有患者行冠状动脉CT血管成像(coronary computed tomography angiography,CCTA)检查,测量FAI和FPI值。对ACS患者跟踪随访,根据术后1年主要不良心血管事件(major adverse cardiovascular events, MACE)的发生情况,将ACS患者分为MACE组(
n
=108)和非MACE组(
n
=226)。检测并比较2组的基线资料、CCTA数据以及实验室检查数据,采用多因素Logistic回归分析FAI和FPI与ACS患者预后的关系,并绘制受试者工作特征(receiver operating caracteristic, ROC)曲线评估其预测效能。
结果
2
334例ACS患者中,108例(32.34%)发生MACE。与非MACE组(226例)比较,MACE组糖尿病患病率(72.22%
vs
31.86%)、左主干病变比例(18.52%
vs
7.08%)显著升高,而手术成功率(79.63%

冠状动脉FAI和FPI可作为ACS患者预后的独立预测指标,其数值变化与斑块稳定性及炎症状态密切相关。
Objective To explore the predictive value of fat attenuation index (FAI) and fibrous plaque index (FPI) for the prognosis of patients with acute coronary syndrome (ACS). Methods A retrospective cohort study was conducted on 334 ACS patients undergoing percutaneous coronary intervention (PCI) in the First Affiliated Hospital of Army Military Medical University and Yongchuan Hospital of Chongqing Medical University from March 2021 to July 2023. All patients received coronary computed tomography angiography (CCTA) to measure FAI and FPI. According to the occurrence of major adverse cardiovascular events (MACE) with 1 year of follow-up, they were divided into MACE group (n=108) and non-MACE group (
n
=226). The baseline data, CCTA data and results of laboratory tests were collected and compared between the 2 groups. Multivariate logistic regression analysis was used to analyze the relationship of FAI and FPI with the prognosis of ACS patients, and ROC curve was drawn to evaluate its predictive efficiency. Results Among the 334 ACS patients, 108 (32.34%) experienced MACE. When compared with the non-MACE group, the MACE group exhibited significantly larger proportions of diabetes (72.22%
vs
31.86%) and left main coronary artery disease (18.52%
vs
7.08%), but lower success rate of operation (79.63%
vs
93.81%,
P
<
0.05). Radiologic results showed that the proportion of severe stenosis (20.37%
vs
10.62%), FAI (-80.12±6.41 HU
vs
-72.34±7.09 HU) and FPI (0.58±0.41
vs
0.26±0.12) were obviously increased in the MACE group than the non-MACE group (
P
<
0.05). Laboratory tests indicated that there were statistical differences between the 2 grou
ps in high-density lipoprotein-cholesterol (HDL-C, 1.20±0.15
vs
1.09±0.16 mmol/L), miR-126 (0.91±0.12
vs
0.96±0.15) and SST2 (38.45±5.67
vs
34.30±4.89 ng/mL,
P
<
0.05). Multivariate Logistic regression analysis revealed that FAI (
OR
=1.200, 95%
CI
: 1.136~1.268), FPI (
OR
=63.157, 95%
CI
: 14.126~282.374), moderate stenosis (
OR
=1.332, 95%
CI
: 1.024~1.859), severe stenosis (
OR
=1.480, 95%
CI
: 1.074~2.039), miR-126 (
OR
=0.007, 95%
CI
: 0.001~0.077), and sST2 (
OR
=1.192, 95%
CI
: 1.113~1.277) were independent predictors of MACE (
P
<
0.05). ROC curve analysis displayed that stenosis degree (AUC=0.622, 95%
CI
: 0.561~0.683,
P
=0.001), FAI (AUC=0.790, 95%
CI
: 0.741~0.839,
P
=0.001) and FPI (AUC=0.700,95%
CI
:0.638~0.761,
P
=0.001), miR-126(AUC=0.646, 95%
CI
:0.584~0.707,
P
=0.001), sST2 (AUC=0.700,95%
CI
: 0.638~0.761,
P
=0.001) had certain predictive values for ACS prognosis. Conclusion Coronary FAI and FPI can be used as independent prognostic indicators of ACS patients, and their numerical changes are closely related to plaque stability and inflammatory state.
