Impact Of CT-FFR Guided Intraoperative Strategy For Percutaneous Coronary Intervention (PCI) On Patient Prognosis

OBJECTIVE: To analyze the correlation between the value of CT flow reserve fraction(CT-FFR)and the choice of PCI strategy in patients with coronary heart disease.METHODS: Patients who underwent percutaneous coronary intervention between April1,2021 and September 31,2021 were included.Images of coronary CTA were uploaded to the software processing center of CT-FFR.With 0.8 as the threshold value,CT-FFR≤0.8 and the patients who finally received interventional therapy for this vessel during the operation and CT-FFR> were selected.0.8 And the patients who received drug optimization treatment after coronary angiography were classified as the experimental group,and the patients who did not receive CT-FFR examination and were only judged by the naked eye were classified as the control group.Clinical data of the two groups were compared,and patients in the two groups were followed up for at least 1 year.The primary endpoint of follow-up was the unplanned readmission rate of the two groups.According to the causes of readmission,the patients were divided into MACE events and non-MACE events,and the readmission rate and the incidence of MACE events were analyzed for differences between the two groups during follow-up.RESULTS: 1.There was no significant difference in the incidence of MACE between the experimental group and the control group(P=0.755).2.Comparison of baseline data between the control group and the experimental group: the proportion of positive surgical results in the experimental group was higher than that in the control group(P<0.05,P=0.038)2.Comparison of readmission rate between control group and experimental group: The readmission rate of control group was higher than that of experimental group(P<0.05,P=0.044)CONCLUSION:1.CT-FFR value consistent with PCI strategy selection could not reduce the incidence of MACE events within 1 year;2.Patients who underwent coronary CTA examination had higher positive rate of coronary intervention.3.CT-FFR values consistent with PCI intraoperative strategies can reduce the readmission rate of patients within 1 year and improve the prognosis of patients.
