摘要

目的:分析弥散性冠状动脉病变(diffused coronary artery disease,DCAD)患者冠状动脉内膜剥脱术(coronary endarterectomy,CE)后发生围术期心肌梗死(perioperative myocardial infarction,PMI)的危险因素并构建预测模型.方法:回顾性选择2021年8月至2023年8月山东第一医科大学附属职业病医院收治的350例行CE治疗的DCAD患者临床资料作为研究对象,以简单随机抽样法分为建模组与验证组(7∶3).并根据患者术后48h内PMI发生情况进行分组,将发生PMI患者临床资料纳入PMI组,将未发生PMI患者临床资料纳入无PMI组.采用二元Logistics 回归分析造成DCAD患者CE术后PMI发生的危险因素并构建列线图,以验证组数据对列线图模型进行外部验证.结果:建模组发生 PMI64 例(26.1％),验证组发生 PMI25 例(23.8％)(x2=0.207,P=0.649);PMI组Syntax评分、LVEDD、hs-CRP水平及合并糖尿病患者占比高于无PMI组,LVEF、肌酐清除率低于无PMI组(P＜0.05);Syntax评分、LVEDD、hs-CRP高水平,合并糖尿病是DCAD患者CE术后PMI发生的危险因素(OR＞1,P＜0.05),LVEF、肌酐清除率高水平是患者术后PMI发生的保护因素(OR＜1,P＜0.05);建模组 AUC 为 0.960(95％CI:0.928～0.992,P＜0.001),验证组 AUC 为 0.953(95％CI:0.917～0.988,P＜0.001).结论:Syntax评分、LVEDD、hs-CRP、合并糖尿病、LVEF、肌酐清除率高水平是DCAD患者CE术后PMI发生的独立因素,根据其构建模型预测效能较好.

Abstract

Objective:To analyze the risk factors of myocardial infarction(PMI)after coronary endarterectomy(CE)in patients with diffuse coronary artery disease(DCAD)and to construct a predictive model.Methods:A retrospective study was conducted to select the clinical data of 350 patients with DCAD who underwent CE treatment in Shandong Provincial Medical College/First Affiliated Hospital of Shandong Provincial Medical College from August 2021 to August 2023 as the research objects.They were divided into modeling group and verification group(7∶3 ratio)by simple random sampling method.The clinical data of patients with PMI were included in the PMI group,and the clinical data of patients without PMI were included in the non-PMI group.Baseline data of patients were collected.Binary logistic regression analysis was used to analyze the risk factors of PMI after CE in DCAD patients and construct a nomogram to verify the nomogram model.Results:PMI occurred in 64 cases(26.1％)in the modeling group and 25 cases(23.8％)in the validation group(x2=0.207,P=0.649);The Syntax score,LVEDD,hs-CRP level and proportion of patients with diabetes mellitus in the PMI group were higher than those in the non-PMI group,while LVEF and creatinine clearance rate were lower than those in the non-PMI group(P＜0.05);The high levels of Syntax score,LVEDD,hs-CRP and diabetes mellitus were the risk factors of PMI after CE in DCAD patients(OR＞1,P＜0.05),and high levels of LVEF and creatinine clearance rate were protective factors for PMI after patients(OR＜1,P＜0.05);The AUC of the modeling group was 0.960(95％CI:0.928-0.992,P＜0.001),and the AUC of the validation group was 0.953(95％CI:0.917-0.988,P＜0.001).Conclusion:Syntax score,LVEDD,hs-CRP,diabetes mellitus,LVEF and high creatinine clearance rate are independent factors for PMI after CE in DCAD patients,and the prediction efficiency of the model constructed according to them is better.
