摘要:

目的 探讨C反应蛋白(CRP)/前白蛋白(PA)比值与急性心力衰竭(AHF)患者预后之间的相关性。方法 选取2018年1月—2020年1月上海中医药大学附属市中医医院急性左心心力衰竭患者79例。收集所有患者入院时的临床资料和实验室检测结果,对所有患者进行随访,随访截止时间为2021年1月,随访终点事件为全因死亡。采用受试者工作特征(ROC)曲线确定CRP/PA比值判断AHF患者死亡的最佳临界值。采用Pearson相关分析评估CRP与PA之间的相关性。采用Kaplan-Meier生存曲线和Log-rank χ2检验分析AHF患者的生存情况。采用Cox比例风险模型评估AHF患者全因死亡的危险因素。结果 Pearson相关分析结果显示,CRP与PA呈负相关(r=-0.37,P=0.001)。ROC曲线分析结果显示,CRP/PA比值判断AHF患者死亡的曲线下面积为0.74,最佳临界值为0.119 9。将所有AHF患者按最佳临界值分为CRP/PA比值≤0.119 9组(36例)和CRP/PA比值>0.119 9组(43例)。Kaplan-Meier生存曲线分析结果显示,CRP/PA比值≤0.119 9组生存率显著高于CRP/PA比值>0.119 9组(Log-rank χ2=22.27,P<0.001)。Cox回归分析结果显示,校正年龄、性别、左心室射血分数(LVEF)、血清肌酐(SCr)、B型钠尿肽(BNP)、糖尿病史、舒张压、总胆红素(TB)、白蛋白(Alb)后,CRP/PA比值>0.119 9的AHF患者死亡风险比CRP/PA比值≤0.119 9的AHF患者高9.03倍[风险比(HR)=9.03,95%可信区间(CI)为2.88~28.29]。结论 高CRP/PA比值与AHF患者全因死亡密切相关。CRP/PA比值可能有助于AHF患者的危险分层。

Abstract:

Objective To investigate the correlations between the ratio of C-reactive protein(CRP) to prealbumin(PA) and the prognosis of patients with acute heart failure(AHF). Methods A total of 79 patients with AHF treated at the Affiliated Hospital of Traditional Chinese Medicine of Shanghai University of Traditional Chinese Medicine were enrolled retrospectively. The clinical data and laboratory determination results at admission were collected. All the patients were followed with an end date of January 2021 and a primary outcome of all-cause mortality. The optimal cut-off value of CRP/PA to predict AHF patient mortality was determined by receiver operating characteristic(ROC) curve. Pearson correlation analysis was used to determine the correlation between CRP and PA. Patient survival was evaluated by Kaplan-Meier survival curve and Log-rank χ2 test. Risk factors for all-cause mortality were identified by Cox proportional hazard ratio. Results Pearson correlation analysis showed that CRP was negatively correlated with PA(r=-0.37,P=0.001). The results of ROC curve analysis showed that the area under curve of CRP/PA to predict AHF mortality was 0.74 with an optimal cut-off value of 0.119 9. The patients were classified into CRP/PA ≤0.119 9 group(36 cases) and CRP/PA >0.119 9 group(43 cases) according to the optimal cut-off value. Kaplan-Meier survival curve analysis showed that the survival rate of CRP/PA ≤0.119 9 group was higher than that of CRP/PA >0.119 9 group(Log-rank χ2=22.27,P<0.001). Cox regression analysis showed that after adjusting for age,sex,left ventricular ejection fraction(LVEF),serum creatinine(SCr),B-type natriuretic peptide(BNP),history of diabetes mellitus,diastolic blood pressure,total bilirubin(TB) and albumin(Alb),patients with CRP/PA >0.119 9 had a 9.03-fold increased risk of mortality than those with CRP/PA ≤0.119 9 [hazard ratio(HR)=9.03,95% confidence interval(CI) 2.88-28.29]. Conclusions High CRP/PA is related to all-cause mortality in patients with AHF,and it is helpful for risk stratification.
