摘要:
目的 探究射血分数保留型心衰(heart failure with preserved ejection fraction,HFpEF)患者中血清微小核糖核酸-125b-5p(microRNA-125b-5p,miR-125b-5p)、心功能相关指标与心肌损伤的相关性分析。 方法 本研究为横断面研究,选取2023年12月至2025年4月期间于衡水市人民医院接受治疗的225例HFpEF患者,按照美国纽约心脏病学会(New York Heart Association,NYHA)心功能分级将HFpEF患者分为60例Ⅳ级组、98例Ⅲ级组、67例Ⅱ级组。对比各组miR-125b-5p、心功能、心肌损伤相关指标水平。对患者随访12个月,记录患者心血管不良事件(Major adverse cardiovascular events,MACEs)的发生情况,根据MACEs发生情况分为MACEs组(67例)、非MACEs组(158例)。收集各组患者临床资料,比较患者血清miR-125b-5p、心功能、心肌损伤指标水平;Pearson相关分析miR-125b-5p、心功能相关指标与心肌损伤的关系;多因素Logistic回归分析HFpEF患者发生MACEs的风险因素;用受试者工作特征(receiver operating characteristic ,ROC)曲线评估miR-125b-5p、心功能指标对HFpEF患者心血管不良事件的预测价值。 结果 与Ⅱ级相比,Ⅲ级、Ⅳ级组LVEF、miR-125b-5p水平下降,心肌肌钙蛋白 I(cardiac troponin I,cTnI)、N 末端 B 型利钠肽原(N-terminal pro-B-type natriuretic peptide,NT-proBNP)、心室舒张末期内径(left ventricular end diastolic diameter,LVEDD)、左心室质量指数(left ventricular mass index,LVMI)水平和T1 mapping、细胞外容积分数(extracellular volume fraction,ECV)值均上升;与Ⅲ级相比,Ⅳ级组miR-125b-5p、左室射血分数(left ventricular ejection fraction,LVEF)下降,cTnI、NT-proBNP、LVEDD、LVMI水平与T1 mapping、ECV值上升(P < 0.05)。行Logistic回归分析发现,在调整了混杂因素后,LVEF、HDL-C、红细胞比容、cTnI、NT-proBNP、miR-125b-5p均是影响HFpEF患者MACEs发生的影响因素;Pearson相关分析,cTnI、NT-proBNP、T1 mapping、ECV值与LVEF、miR-125b-5p呈负相关,与LVMI、LVEDD呈正相关(P < 0.05)。ROC曲线显示LVEF、LVMI、LVEDD、miR-125b-5p联合检测对MACEs发生的AUC值、敏感度及准确度均高于单一指标检测(P < 0.05)。 结论 HFpEF患者血清 miR-125b-5p水平降低、心功能指标异常,并与心肌损伤之间有关联性,miR-125b-5p、心功能指标联合检测对患者MACEs发生有较高的预测价值。 Abstract:Objective To investigate the correlation between serum microRNA-125b-5p (miR-125b-5p), cardiac function indexes and myocardial injury in patients with heart failure with preserved ejection fraction (HFpEF), and their predictive value for major adverse cardiovascular events (MACEs). Methods A total of 225 patients with HFpEF treated in Hengshui People’s Hospital from December 2023 to April 2025 were selected. According to New York Heart Association (NYHA) cardiac function classification, they were divided into class Ⅱ group (67 cases), class Ⅲ group (98 cases) and class Ⅳ group (60 cases). Serum miR-125b-5p, cardiac troponin I (cTnI), N-terminal pro-B-type natriuretic peptide (NT-proBNP), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), left ventricular mass index (LVMI), T1 mapping and extracellular volume fraction (ECV) were detected in each group. All patients were followed up for 12 months, and the occurrence of MACEs was recorded. The patients were divided into MACEs group (67 cases) and non-MACEs group (158 cases). Collect clinical data from patients in each group and compare levels of serum miR-125b-5p, cardiac function, and markers of myocardial injury; Pearson correlation analysis of the relationship between miR-125b-5p, cardiac function-related indicators, and myocardial injury; Multivariate logistic regression analysis was performed to identify risk factors for MACE in patients with HFpEF; receiver operating characteristic (ROC) curves were used to evaluate the predictive value of miR-125b-5p and cardiac function indices for cardiovascular adverse events in patients with HFpEF. Results Compared with the Class II group, the Class III and IV groups showed decreased LVEF and miR-125b-5p levels, as well as elevated levels of cardiac troponin I (cTnI), N-terminal pro-B-type natriuretic peptide (N-terminal pro-B-type natriuretic peptide, NT-proBNP), left ventricular end-diastolic diameter (LVEDD), and left ventricular mass index (LVMI), while T1 mapping and extracellular volume fraction (ECV) values were all elevated; Compared with the Grade III group, the Grade IV group showed decreased levels of miR-125b-5p and left ventricular ejection fraction (LVEF), as well as increased levels of cTnI, NT-proBNP, LVEDD, and LVMI, along with elevated T1 mapping and ECV values (P < 0.05). Logistic regression analysis revealed that, after adjusting for confounding factors, LVEF, HDL-C, hematocrit, cTnI, NT-proBNP, and miR-125b-5p were all risk factors for the occurrence of MACE in patients with HFpEF; Pearson correlation analysis revealed that cTnI, NT-proBNP, T1 mapping, and ECV were negatively correlated with LVEF and miR-125b-5p, and positively correlated with LVMI and LVEDD (P < 0.05). The ROC curve showed that the combined assessment of LVEF, LVMI, LVEDD, and miR-125b-5p had higher AUC values, sensitivity, and accuracy for predicting the occurrence of MACEs than any single parameter (P < 0.05). Conclusion Patients with HFpEF have reduced serum miR-125b-5p levels and abnormal cardiac function parameters, which are associated with myocardial injury; combined testing of miR-125b-5p and cardiac function parameters has high predictive value for the occurrence of MACE in these patients. -
