摘要: 目的 探讨左室舒张末压(LVEDP)联合踝臂指数(ABI)对急性心肌梗死(AMI)经皮冠状动脉介入治疗(PCI)无复流及预后的预测价值。 方法 将我院2017~2018年收治的280例AMI病人作为研究对象,均行PCI治疗,根据术中复流发生情况分为正常组、无复流组。比较2组病人的临床资料、LVEDP、ABI等,采用Logistic 回归分析无复流发生的危险因素。PCI术后随访1年,记录主要不良心血管事件(MACE),比较2组病人MACE发生情况,采用ROC曲线分析LVEDP联合ABI对预后的预测价值。 结果 无复流组病人的LVEDP、Killip分级为Ⅲ~Ⅳ级人数占比、肌酸激酶同工酶峰值、BNP水平均明显高于正常组(P<0.05),LVEF、ABI明显低于正常组(P<0.01)。Logistic回归分析显示,心功能Killip分级、LVEDP、ABI、BNP水平是AMI病人PCI术中发生无复流的独立危险因素(P<0.05)。随访1年,正常组全因死亡率(4.33% 比 11.11%)以及总MACE发生率(16.83 % 比 34.72%)明显低于无复流组,差异有统计学意义(P<0.05)。LVEDP和ABI联合预测MACE的AUC为0.875(95%CI:0.819~0.931),明显高于LVEDP、ABI单独预测(P<0.05)。 结论 LVEDP和ABI是AMI病人PCI术中发生无复流的独立危险因素,两者联合检测对于病人预后预测具有潜在应用价值。

Abstract: Objective To explore the predictive value of left ventricular end diastolic pressure (LVEDP) combined with ankle-brachial index (ABI) on no-reflow and prognosis in the elderly patients receiving percutaneous coronary intervention (PCI) for acute myocardial infarction(AMI). Methods A total of 280 patients with AMI admitted in our hospital from January 2017 to December 2018 were divided into normal group and no-reflow group according to the occurrence of reflow during the operation. The clinical data, the levels of LVEDP and ABI were compared between the two groups, and Logistic regression was used to analyze the risk factors of no-reflow. The patients were followed up for one year after PCI, and the incidence of major adverse cardiovascular events (MACE) was recorded and compared. The prediction value of LVEDP and ABI was analyzed by receiver operating characteristic (ROC) curve. Results The levels of LVEDP and B-type natriuretic peptide (BNP), the proportion of Killip grades Ⅲ-Ⅳ, the peak of creatine kinase isoenzyme in no-reflow group were significantly higher than those in normal group (P<0.05), and the levels of left ventricular ejection fraction (LVEF) and ABI were significantly lower than those in normal group (P<0.001). Logistic regression analysis showed that Killip classification of cardiac function, LVEDP, BNP and ABI were independent risk factors of no-reflow during PCI (P<0.05). After 1 year of follow-up, all-cause mortality (4.33% vs 11.11%) and total MACE incidence rate (16.83% vs 34.72%) in normal group were significantly lower than those in no-reflow group (P<0.05). The area under the ROC curve (AUC) of LVEDP combined with ABI predicting MACE was significantly higher than LVEDP and ABI alone (P<0.05). Conclusions LVEDP and ABI are the independent risk factors for no-reflow of AMI through PCI intervention. The combined detection shows potential application value for the prognosis prediction.
