摘要: 目的:通过建立冠状动脉慢性完全闭塞(CTO)患者完全血运重建的多重危险因素回归模型,分析冠状动脉CT血管成像(CCTA)及CT-RECTOR评分对CTO的预测价值。方法:连续入选2019年1月—2019年9月于我科住院并符合纳入标准的对象197例,其中CCTA组72例、对照组125例。收集患者人口学特征、临床资料及影像学资料,建立完全血运重建患者的多因素Logistic回归模型并评价其预测价值。结果:两组介入成功率分别为88.9%、76.8%。CCTA组累计射线照射时间为28.0(22.5,34.8)min、累计照射剂量为2510(1228,3450)mGY,均低于对照组(均P＜0.05)。构建多重危险因素回归模型,结果显示CCTA为CTO患者完全血运重建的保护性因素,其OR值为0.351。CT-RECTOR评分预测CTO介入成功的受试者工作特征曲线下面积为0.742。结论:CCTA及CT-RECTOR评分对CTO完全血运重建具有预测价值。

Abstract: Objective: To establish the multiple risk factors models for patients with chronic total occlusion(CTO) and then quantitatively analyze the predictive value of Coronary Computed Tomography Angiography(CCTA) and CT-RECTOR score. Method: A total of 197 CTO inpatients were enrolled consecutively from January 2019 to September 2019. And they were divided into 2 groups of CCTA(n=72), and control(n=125). All demographic clinical data and angiography were collected by the physicians. Result: The successful rates of two groups were 88.9% and 76.8%, respectively. The total time was 28.0(22.5, 34.8) and dose of irradiated exposure was 2510(1228, 3450), which were lower in CCTA group than control group(all P＜0.05). Besides, CCTA was independent protected factor, which OR was 0.351(P＜0.05). In addition, the area under the receiver operating characteristic curve(ROC-AUC) of CT-RECTOR score was 0.742.Conclusion: CCTA and CT-RECTOR indicated the predictable value of CTO complete revascularization. -
