Value of Peripheral Coronary Fat CT Attenuation Index Combined with CT-FFR in Predicting MACE Events in Patients with Acute Coronary Syndrome
Objective To investigate and analyze the value of peripheral coronary fat CT attenuation index combined with CT-FFR in predicting MACE events in patients with acute coronary syndrome.Methods We selected 162 ACS patients who underwent PCI surgery in our hospital from January 2020 to July 2022,and divided them into MACE group(37 cases)and non-MACE group(125 cases)according to whether MACE occurred 1 year after surgery.The clinical data of patients in the two groups were recorded,and FAI and CT-FFR were examined,multifactorial logistic regression analysis was performed,and ROC curves were used to analyse the predictive value of FAI and CT-FFR on the occurrence of MACE after PCI in ACS patients.Results FAI was significantly higher in patients in the MACE group than in those in the non-MACE group(P＜0.05),and CT-FFR was significantly lower in patients in the MACE group than in those in the non-MACE group(P＜0.05).CT-FFR,FAI,age,and the straight number of vascular lesions entered into the regression model(P＜0.05),and were the independent risk factors affecting the occurrence of MACE after PCI in patients with ACS.ROC curve was used to analyse the predictive value of FAI and CT-FFR for MACE after PCI in patients with ACS,and the results showed that the area under the curve of FAI was 0.695,the area under the curve of CT-FFR was 0.771,and the area under the curve of FAI combined with CT-FFR was 0.943.Condusion The CT attenuation index of peripheral coronary fat combined with CT blood flow reserve fraction has a good predictive value for the occurrence of MACE in patients with coronary syndrome after PCI.Improving the relevant examination and evaluation before surgery is of great significance for the timely adoption of effective preventive and therapeutic countermeasures for high-risk patients,and for improving the clinical prognosis of patients.
