摘要
目的:探究冠状动脉(冠脉)造影衍生的微循环阻力指数(AMR)对ST段抬高型心肌梗死(STEMI)患者经皮冠脉介入治疗(PCI)后心室重构的预测价值。方法:回顾性纳入2019年4月至2023年1月于首都医科大学附属北京安贞医院接受PCI的STEMI患者168例。患者分别于PCI术后3~7 d和3个月时接受急性期与恢复期心脏磁共振成像(CMR)检查。恢复期左心室舒张末期容积较急性期增加20%及以上认为发生心室重构,据此将入选患者分为心室重构组(n=49)与无心室重构组(n=119)。比较两组患者的基线临床特征、AMR值及CMR指标。采用Pearson相关性分析评估AMR和急性期CMR显示的微血管阻塞(MVO)范围的相关性。采用Logistic回归分析和受试者工作特征(ROC)曲线评估AMR对STEMI患者PCI术后心室重构的预测价值。结果:168例患者的平均年龄为(56.4±11.4)岁,男性139例(82.7%)。AMR值与急性期CMR显示的MVO范围呈正相关(r=0.42,P<0.01)。心室重构组的AMR值高于无心室重构组[3.00(2.56,3.52)mmHg·s/cm vs.2.48(2.20,2.74)mmHg·s/cm,1 mmHg=0.133 kPa,P<0.01]。多因素Logistic回归分析显示,AMR是STEMI患者PCI术后心室重构的独立预测因素,AMR值每增加0.2 mmHg·s/cm,心室重构风险增加45.1%(OR=1.451,95%CI:1.228~1.714,P<0.01)。AMR预测心室重构的曲线下面积(AUC)为0.769。结论:AMR与MVO范围呈正相关,是STEMI患者PCI术后心室重构的独立预测因素。
Objectives:To explore the correlation between angiography-derived microcirculatory resistance(AMR)and microvascular obstruction(MVO)extent,and AMR’s predictive value for ventricular remodeling in patients with ST-segment elevation myocardial infarction(STEMI)post-primary percutaneous coronary intervention(PCI).Methods:This retrospective study included STEMI patients who underwent PCI at Beijing Anzhen Hospital from April 2019 to January 2023.Patients underwent acute and follow-up cardiac magnetic resonance(CMR)examinations 3-7 days and 3 months post-PCI.Ventricular remodeling was defined as a 20%or more increase in left ventricular end-diastolic volume at follow-up.Patients were divided into ventricular remodeling and non-ventricular remodeling groups.Baseline clinical characteristics,AMR values and CMR indices of both groups were compared.Pearson's correlation coefficient was used to explore the correlation between AMR and MVO extent on CMR.Logistic regression and receiver operating characteristic curve analysis were employed to evaluate the predictive performance of AMR for ventricular remodeling.Results:A total of 168 STEMI patients([56.4±11.4]years,139[82.7%]males)were included,with 49(29.2%)in the ventricular remodeling group and 119(70.8%)in the non-ventricular remodeling group.AMR was positively correlated with MVO extent on CMR(r=0.42,P<0.01).Compared to the non-ventricular remodeling group,patients in the ventricular remodeling group exhibited a higher AMR value(3.00[2.56,3.52]mmHg∙s/cm vs.2.48[2.20,2.74]mmHg∙s/cm,1 mmHg=0.133 kPa,P<0.01).Multivariate logistic analysis showed that AMR was independently associated with ventricular remodeling post-PCI in STEMI patients.For every 0.2 mmHg·s/cm increase in AMR,the risk for ventricular remodeling increased 45.1%(adjusted OR=1.451,95%CI:1.228-1.714,P<0.01).Area under the curve of AMR for predicting ventricular remodeling was 0.769.Conclusions:AMR is positively correlated with MVO extent and is an independent predictor for ventricular remodeling in STEMI patients post-PCI.
