摘要
目的 探讨充血性心力衰竭（CHF）患者血清脑钠肽（BNP）和肌钙蛋白Ⅰ（cTnI）水平与其心功能的相关性.方法 采用电化学发光免疫分析法测定75例CHF患者（观察组）和健康体检正常者30例（对照组）血清BNP和cTnI水平,观察两组BNP和cTnl水平差异及与心功能分级的相关性.结果 观察组BNP和cTnI水平分别为（1 132.4 ±220.5）ng/L、（825.3 ±186.2）ng/L,均明显高于对照组的（38.2 ±16.0）ng/L、（26.9 ±12.7）ng/L（t=3.897、4.127,均P＜0.05）.观察组不同心功能分级之问的BNP和cTnI水平差异均有统计学意义（F=4.765、5.876,均P＜0.05）;随着心功能分级的增加,BNP和cTnI水平均显著升高,经直线相关性分析,BNP和cTnI水平与心功能分级之间均呈显著正相关（r=0.853、0.647,均P＜0.05）.结论 CHF患者血清BNP和cTnI水平均显著升高,而且与心功能分级密切相关,可作这CHF严重程度的评价指标.
Objective To investigate the relations between BNP and cTnI leveh in patients with CHF and cardiac function.Methods 75 patients with CHF were selected as observation group and another 30 healthy people were selected as control group.BNP and cTnI levels were detected by electrochemiluminescence immunoassay and the data were analyzed.Results BNP and cTnI of observation group were significantly higher than control group,the difference was statistically significant（t=3.897,4.127,all P＜0.05）;comparison of BNP and cTnI levels in different classification of cardiac function of observation group had significant difference（F=4.765,5.876,allP＜0.05）;Linear corrlation analysis showed that：BNP and cTnI both positively correlated to classification of cardiac function（r=0.853,0.647,all P＜0.05）,BNP and cTnI increased significantly with the increase of cardiac function classification.Conclusion BNP and cTnI increased significantly in patients with CHF and closely related with cardiac function.they were ideal index to evaluate the CHF severity and had a good clinical value to judge the status and function of heart in patients with CHF.
