摘要:

目的 探讨急性心肌梗死冠状动脉介入手术后心肌微循环灌注障碍的影响因素及与乳酸关系。方法 选取2019年2月至2020年7月我院收治的急性心肌梗死冠状动脉介入手术患者132例,根据术后TIMI心肌组织灌注分级(TMPG)分为两组,即观察组56例,TMPG 0~2级,心肌微循环灌注不良;对照组76例,TMPG 3级,心肌微循环灌注良好。对比两组各项资料,经二元Logistic回归分析影响因素。运用ROC曲线分析乳酸预测效能, Pearson法分析乳酸与心肌微循环灌注状态以及冠状动脉血流(Thrombolysis in myocardial infarction, TIMI)分级、症状-至首次医疗接触(FMC to heparin, FMC)时间、FMC至肝素给予(first medical contact time, FMC-H)时间、不良心血管事件(MACEs)、糖尿病病史、冠状动脉慢血流、高血压病史、吸烟史相关性。结果 FMC-H>4 h、症状-FMC>4 h、TIMI血流0级~2级、有MACEs、有糖尿病病史、冠状动脉慢血流、有高血压病史、有吸烟史是影响患者发生心肌微循环灌注障碍的独立因子(P<0.05)。乳酸预测心肌微循环灌注情况的准确率为93.94%,灵敏度91.10%,特异度96.10%。观察组乳酸水平高于对照组,FMC-H时间、症状-FMC时间长于对照组,TIMI血流低于对照组(P<0.05)。心肌微循环灌注状态与乳酸呈负相关性;乳酸与FMC-H时间、症状-FMC时间呈正相关性,与TIMI血流、MACEs、糖尿病病史、冠状动脉慢血流、高血压病史、吸烟史呈负相关性。结论 MACEs、FMC-H时间、FMC时间、TIMI分级以及慢性疾病、吸烟史均是影响急性心肌梗死冠状动脉介入手术患者发生心肌微循环灌注障碍的因素,故需加以预防、干预,从而减轻心肌缺血-再灌注损伤。而乳酸可作为预测心肌微循环灌注状态有效指标。

Abstract:

Objective To explore the influencing factors of myocardial microcirculation perfusion(MMP) disorder after percutaneous coronary intervention(PCI) in acute myocardial infarction(AMI) and its relationship with lactic acid. Methods Totally 132 patients undergoing PCI for AMI admitted to our hospital between February 2019 and July 2020 were selected, they were divided into the observation group (TMPG 0-2, poor MMP; n=56) and the control group (TMPG 3, good MMP; n=76) according to TIMI myocardial perfusion grading (TMPG), the data of two groups were collected, and binary logistic regression were used to analyze the influencing factors. ROC curve, lactic acid prediction, and Pearson method were used to analyze the correlation between lactic acid and the data, such as MMP, thrombolysis in myocardial infarction(TIMI), symptoms-to the first medical contact(FMC), FMC to heparin(FMC-H) administration, mojor adverse cardiovascular events(MACEs), history of diabetes, chronic slow flow(CSF), history of hypertension, history of smoking. Results The occurrence of MMP disorders in patients FMC-H>4 h, symptom-FMC>4 h, TIMI blood flow grade 0-2, MACEs, history of diabetes, CSF, history of hypertension, history of smoking were all independent factors that affected the occurrence of MMP disorders in patients(P<0.05). The accuracy, sensitivity and the specificity in predicting MMP by lactic acid was 93.94%, 91.10%, 96.10%, respectively. The lactic acid in observation group was higher than in the control group, FMC-H time and symptom-FMC time were longer than in the control group, and TIMI blood flow was lower than in the control group (P<0.05). The level of lactic acid was positively correlated with FMC-H time, symptom-FMC time, and negatively correlated with MMP, TIMI blood flow, MACEs, history of diabetes, CSF, history of hypertension, and smoking history. Conclusion MACEs, FMC-H time, FMC time, TIMI grade, chronic disease, and smoking history are all factors that affect MMP in patients undergoing PCI for AMI. Therefore, prevention and intervention are needed to reduce myocardial ischemia and reperfusion injury. Lactic acid can be used as an effective indicator to predict myocardial microcirculation perfusion status.
