冠状动脉CT血管成像血管储备分数对冠心病不良心脏事件的预测价值分析

Analysis of the predictive value of coronary CT angiography vascular reserve fraction for adverse cardiac events in coronary artery disease

目的:探讨预测冠心病不良心脏事件(MACE)中采用冠状动脉CT血管成像血管储备分数的价值。方法:本研究将2022年3月—2023年4月济宁市第一人民医院行冠状动脉CT血管成像的冠心病患者80例作为研究对象,根据是否发生MACE分为MACE组31例和无MACE组49例。比较两组一般资料及冠状动脉血管储备分数,并采用Logistic回归分析将冠状动脉血管储备分数对MACE的预测价值的相关性分析。结果:两组一般资料比较,差异无统计学意义(P> 0.05);MACE组冠状动脉血管储备分数值比无MACE组低,差异有统计学意义(P<0.05);经多因素Logistic回归分析显示,冠状动脉血管储备分数是影响冠心病患者MACE发生的独立危险因素。结论:通过比较有无MACE患者的一般资料以及冠状动脉血管储备分数,发现患者的基础疾病、年龄性别、等信息对MACE的影响较小,而通过多因素Logistic回归分析发现MACE的独立危险因素包含冠状动脉血管储备分数值,表明冠状动脉CT血管成像血管储备分数对MACE具有预测价值。

Objective To investigate the value of using coronary CT angiography vascular reserve fraction in the prediction of coronary heart disease major cardiovascular adverse event(MACE).Methods 80 coronary heart disease patients who underwent coronary CT angiography in the First People's Hospital of Jining City from March 2022 to April 2023 were taken as the study subjects,and they were divided into 31 cases in the MACE group and 49 cases in the no-MACE group according to whether or not MACE occurred.The general information and coronary vascular reserve score of the two groups were compared,and the correlation of the predictive value of coronary vascular reserve score on MACE was analyzed by logistic regression analysis.Results Comparing the general information of the two groups,there was statistically non significant(P> 0.05);the value of coronary vascular reserve score in the MACE group was lower than that in the group without MACE,and the difference was statistically significant(P <0.05);the multivariate logistic regression analysis showed that the value of coronary vascular reserve score was an independent risk factor affecting the occurrence of MACE in patients with coronary heart disease.Conclusion By comparing the general information of patients with and without MACE and the coronary vascular reserve score,it was found that the patients' underlying diseases,age and gender,and other information had less influence on MACE,while the independent risk factors of MACE were found to include the value of coronary vascular reserve score by multivariate logistic regression analysis,which indicated that coronary CT angiography vascular reserve score had a predictive value for MACE,suggests that coronary CT angiography vascular reserve score has a predictive value for MACE.
