摘　　要：目的探讨射血分数降低的急性心力衰竭患者血清钠离子对病情严重程度及预后的评估价值。方法选取2020年1月至2022年1月聊城市第三人民医院收治的120例射血分数降低的急性心力衰竭患者为研究对象,其中男性73例,女性47例,年龄62~81(69.17±4.36)岁。所有患者均进行血清钠离子水平检测和心功能检查,比较不同心功能分级患者的血清钠离子水平和左心室射血分数(LVEF),分析血清钠离子与心功能分级、LVEF的相关性。随访所有患者6个月,以全因死亡或不良心血管事件为观察终点分为预后不良组和预后良好组,比较两组临床特征,并采用logistic回归分析预后影响因素。结果Ⅱ级、Ⅲ级、Ⅳ级心功能患者的血清钠离子水平分别为(128.64±8.34)mmol/L、(117.34±10.05)mmol/L、(104.13±10.56)mmol/L,差异均有统计学意义(均P<0.05)。Ⅱ级、Ⅲ级、Ⅳ级心功能患者的LVEF分别为(39.46±3.73)%、(33.19±5.58)%、(28.69±5.21)%,差异均有统计学意义(均P<0.05)。相关性分析结果显示,血清钠离子与心功能分级呈负相关(r=-0.644,P<0.05),与LVEF呈正相关(r=0.395,P<0.05)。随访所有患者6个月,以全因死亡或不良心血管事件为观察终点,预后不良一共37例,预后良好一共83例。单因素分析结果显示,预后不良组和预后良好组患者年龄、心功能分级、LVEF、高血压、糖尿病、钠离子水平、服用利尿剂比较,差异均有统计学意义(均P<0.05)。logistic回归分析显示,校正年龄、心功能分级、LVEF、高血压、糖尿病后,两组患者血清钠离子水平差异仍有统计学意义(OR=0.589,95%CI 0.264~0.903,P<0.05)。绘制受试者工作特征曲线分析显示,钠离子对急性心力衰竭患者预后具有显著的预测价值(曲线下面积=0.822,95%CI 0.744~0.899)。结论血清钠离子水平可作为评估射血分数降低的急性心力衰竭患者病情严重程度和预后的有效指标。Objective To explore the value of serum sodium ion in evaluating the severity and prognosis of patients with acute heart failure and decreased ejection fraction.Methods From January 2020 to January 2022,120 patients with acute heart failure and decreased ejection fraction treated in Liaocheng Third People's Hospital were selected as the study objects,including 73 males and 47 females.They were 62-81(69.17±4.36)years old.All the patients'serum sodium level and cardiac function were detected.The serum sodium levels and left ventricular ejection fractions(LVEF)of the patients with different concentric function grades were compared.The correlations between serum sodium level and cardiac function grades and LVEF were analyzed.All the patients were followed up for six months,and were divided into a poor prognosis group and a good prognosis group;all-cause death or adverse cardiovascular events were set as the observation endpoint.The clinical characteristics of the two groups were compared.The prognostic factors were analyzed by logistic regression.Results The levels of serum sodium in the patients with gradeⅡ,Ⅲ,andⅣcardiac function were(128.64±8.34)mmol/L,(117.34±10.05)mmol/L,and(104.13±10.56)mmol/L,respectively,with statistical differences(all P<0.05).The LVEF of the patients with gradeⅡ,Ⅲ,andⅣcardiac function were(39.46±3.73)%,(33.19±5.58)%,and(28.69±5.21)%,respectively,with statistical differences(all P<0.05).The results of correlation analysis showed that serum sodium was negatively correlated with cardiac function grading(r=-0.644,P<0.05),and positively with LVEF(r=0.395,P<0.05).All the patients were followed up for 6 months;all-cause death or adverse cardiovascular events were set as the end point;37 patients had poor prognosis and 83 patients had good prognosis.The results of univariate analysis showed that there were statistical differences in age,cardiac function grade,LVEF,hypertension,diabetes,sodium ion level,and diuretics between the poor prognosis group and the good prognosis group(all
