脑钠肽、肌钙蛋白I、超敏C反应蛋白诊断急性心肌梗死的价值分析

Diagnostic Value of Brain Natriuretic Peptide,Troponin I and Hypersensitive C-Reactive Protein for Acute Myocardial Infarction

目的:探讨脑钠肽(BNP)、心肌肌钙蛋白I(cTnI)、超敏C反应蛋白(hs-CRP)诊断急性心肌梗死(AMI)的价值。方法:选取2021年1月—2023年1月济宁市泗水县人民医院收治的160例AMI患者作为研究对象,抽取患者清晨空腹静脉血,检测BNP、cTnI、hs-CRP水平。以临床综合诊断结果为“金标准”,比较BNP、cTnI、hs-CRP及联合检测诊断AMI的灵敏度、特异度。结果:联合检测诊断AMI的灵敏度、特异度高于BNP、cTnI、hs-CRP单独检测,差异有统计学意义(P<0.05)。结论:BNP、cTnI、hs-CRP联合检测诊断AMI的灵敏度、特异度较高,具有较高的应用价值。

Objective:To investigate the value of brain natriuretic peptide(BNP),cardiac troponin I(cTnI),and hypersensitive C-reactive protein(hs-CRP)in the diagnosis of acute myocardial infarction(AMI).Methods:A total of 160 patients with AMI treated in Sishui County People's Hospital of Jining City from January 2021 to January 2023 were selected as the study subjects.Fasting venous blood was extracted in the morning.The levels of BNP,cTnI and hs-CRP were detected.Clinical comprehensive diagnosis results were used as the“golden standard”to compare the sensitivity and specificity of BNP,cTnI,hs-CRP and combined detection in the diagnosis of AMI.Results:The sensitivity and specificity of the combined detection were higher than those of single detection of BNP,cTnI and hs-CRP,with statistically significant differences(P<0.05).Conclusion:The combined detection of BNP,cTnI,and hs-CRP has a higher sensitivity and specificity in the diagnosis of AMI,and has high application value.
