2、=54)例;选取56 例同期本院心功能体检健康者作为正常组。所有入选者均进行血清NT-proBNP及PaO,检测,分析临床意义。结果:高危组血清NT-proBNP水平最高,其次低危组,正常组最低;高危组PaO2水平最低,其次低危组,正常组最高,差异均有统计学意义(P0.05)。绘制受试者工作特征曲线(ROC曲线)结果显示,血浆NT-proBNP、Pa O,水平对诊断慢性心力衰竭均有理想的诊断效能,曲线下面积(AUC)=0.900、0.880。结论:慢性心力衰竭患者血清NT-proBNP水平呈高表达,PaO,降低,且随着病情加重而不断加剧,可为临床初步确诊慢性心力衰竭提供参考依据。【关键词】慢性

4、ctive:To study the clinical significance of serum N-terminal B-type natriuretic peptide precursor(NT-proBNP)and ateral blood oxygen partial pressure(PaO,)in patients with chronic heart failure.Methods:A total of107 patients with chronic heart failure admitted to our hospital from April 2018 to Novem
5、ber 2019 were selected.Accordingto the NYHA cardiac function classification,26 patients of Grade I and 27 patients of Grade II were included in the low riskgroup(n=53),25 patients of Grade Iland 29 patients of GradelVwere included in the high risk group(n=54),and 56healthy people who had cardiac fun
6、ction examination in our hospital at the same time were selected as the normal group.The levels of NT-proBNP and PaO,in serum were detected in all the participants,and their expression levels andsignificance were analyzed.Results:The serum NT-proBNP level in high-risk group was the highest,followed
7、by low-riskgroup,and the normal group was the lowest.The PaO,in high-risk group was the lowest,followed by low-risk group,andthe normal group was the highest,with a statistical significant difference(P0.05)。低危组和高危组纳入标准:符合2 0 18 年制定的中国心力衰竭诊断和治疗指南2 0 18 41中慢性心力衰竭的诊断标准者;入组前未服用相关药物者;患者或其家属充分了解该研究,且遵循自愿原

11、弊端,纳人样本数量较少、属于单中心研究、未对患者预后进行随访跟踪,希望未来在血清 NT-proBNP 及 PaO,检测与慢性心衰患者的相关性研究中展开大样本、多中心的深入探讨,对本次研究结果加以佐证。综上所述,慢性心衰患者血清NT-proBNP水平呈高表达,PaO,水平低,且随着病情加重而不断加剧,可为临床初步确诊慢性心衰提供参考依据。参考文献1戎成振,卢家忠,王洪巨.慢性心力衰竭患者血浆copeptin、NT-p r o BNP表达变化的意义.山东医药,2018;8(1):49-51.2黄晓莉,郝君锋.慢性心力衰竭患者心功能及血浆copeptin和NT-proBNP检测及临床意义.海南医学,
