结果 与对照组相比,事件组年龄、收缩压、UACR、NT-proBNP的基线水平较高,血钠与左室射血分数较低,差异均有统计学意义(P<0.05)不同程度白蛋白尿组的NYHA分级,血肌酐、血钠、NT-proBNP水平及HF再入院率比较,差异均有统计学意义(P<0.05)其中与正常白蛋白尿组相比,微量白蛋白尿组和大量白蛋白尿组的肌酐、NT-proBNP水平和HF再入院率均较高,差异均有统计学意义(P<0.05)UACR与收缩压、舒张压、NYHA分级、血肌酐、血尿酸呈正相关,与血钠、左室射血分数呈负相关(P<0.05),多因素Logistic回归分析结果显示,年龄、UACR与NT-proBNP是HFpEF患者出院后3个月复发HHF的独立预测因素,受试者操作特征(receiver operator characteristic,ROC)曲线分析显示年龄、UACR、NT-proBNP及联合预测短期HHF再发的曲线下面积分别为0.718、0.757、0.857、0.868结论 UACR与NT-proBNP是HFpEF患者3个月再次发生HHF事件的独立危险因素,两者联合有更高的预测价值[Key] 射血分数保留的心力衰竭;尿白蛋白/尿肌酐;N末端B型利钠肽原;再入院[] R541.6+1 [] A [DOI] 10.3969/j.issn.1673-9701.2023.17.011Value of urine albumin-to-creatinine ratio and NT-proBNP on short-term readmission of heart failure patients with preserved ejection fractionLIU Panfei, ZHANG XiaohongDepartment of Cardiology, the Third Affiliated Hospital of Anhui Medical University (the First Peoples Hospital of Hefei), Hefei 230061, Anhui, China[Abstract] Objective To investigate the predictive value of baseline urinary albumin-to-creatinine ratio (UACR) and N-terminal pro-brain natriuretic peptide (NT-proBNP) for recurrence of hospitalization for heart failure (HHF) 3 months after discharge in patients with heart failure with preserved ejection fraction (HFpEF). Methods A total of 227 patients with HFpEF hospitalized in the third Affiliated Hospital of Anhui Medical University from January 2021 to March 2022 were selected and divided into event group (n=48) and control group (n=162) according to whether HHF recurred within 3 months after discharge. Baseline UACR and NT-proBNP were measured. The differences of general data between the two groups were compared. On the basis of the level of urinary albumin excretion, patients were divided into a normal albuminuria group (n=102), a micro albuminuria group (n=86) and a massive albuminuria group (n=22) and the clinical data of the three groups were compared, and the risk factors of short-term heart failure readmission in HFpEF patients were analyzed by Logistic regression. Results Compared to the control group, the event group had higher baseline levels of age, systolic blood pressure, UACR, NT-proBNP and lower blood sodium and left ventricular ejection fraction, all with statistically significant differences (P<0.05). Compared to the different levels of albuminuria groups, NYHA classification, blood creatinine, blood sodium, NT-proBNP levels and HF readmission rates were all statistically significant (P<0.05). Among them, creatinine, NT-proBNP levels and HF readmission rates were higher in the microalbuminuria and massive albuminuria groups compared to the normal albuminuria group, and the differences were statistically significant (P<0.05). UACR was positively correlated with systolic blood pressure, diastolic blood pressure, NYHA classification, blood creatinine, and blood uric acid, and negatively correlated with blood sodium and left ventricular ejection fraction (P<0.05). Multi-factor Logistic regression analysis showed that age, UACR and NT-proBNP were independent predictors of HHF recurrence 3 months after discharge in patients with HFpEF. Receiver operator characteristic (ROC) curve analysis showed that the area under the curve for age, UACR, NT-proBNP and combined prediction of short-term HHF recurrence was 0.718, 0.757, 0.857 and 0.868, respectively. Conclusion UACR and NT-proBNP are independent risk factors for recurrence of HHF in patients with HFpEF at 3 months, and the combination of UACR and NT-proBNP has higher predictive value.[Key words] Heart failure with preserved ejection fraction; Urine albumin-to-creatinine ratio; N-terminal pro-brain natriuretic peptide; Readmission射血分数保留的心力衰竭(heart failure with preserved ejection fraction,HFpEF)是一种由多种病因发展而来的具有重叠病理生理机制的异质性疾病。
