RESUMO
Objective To investigate the clinical significance of troponin I and N-terminal pro-brain natriuretic peptide detection in the diagnosis of acute myocardial infarction(AMI).Methods The troponin I and N-terminal pro-brain natriuretic peptide(NT-proBNP)were detected in 89 AMI patients(AMI group)and in 102 non-AMI patients(non-AMI group).Results The troponin I and NT-proBNP levels in AMI group were significant higher than those in non-AMI group,and the difference was statistically sig-nificant(P <0.05).Meanwhile,the combined detection of troponin I and NT-proBNP could increase the sensitivity and specificity of AMI′s early diagnosis to 88.8% and 93.1%.Conclusion Early and rapid detection of troponin I and NT-proBNP could significant-ly improve the early diagnosis of acute myocardial infarction in sensitivity and specificity.
