The impact of combined testing of creatine kinase-MB,myoglobin,and cardiac troponin I on the diagnostic efficiency for myocardial infarction patients
Objective To analyze the impact of combined testing of creatine kinase-MB(CK-MB),myoglobin(MYO),and cardiac troponin I(cTnI)on the diagnostic efficiency for patients with myocardial infarction.Methods From January to May 2024,97 patients with chest pain suspected of myocardial infarction were selected in our hospital.All patients underwent CK-MB,MYO,and cTnI tests,with coronary angiography results as the gold standard.The diagnostic efficiency of CK-MB,MYO,and cTnI was compared both individually and in combination.Results Among the 97 patients with chest pain,84 had acute myocardial infarction,and 13 had unstable angina.The sensitivity(96.43%),specificity(92.31%),and accuracy(95.88%)of the combined tests were higher than those of individual tests.Conclusion In the diagnosis of myocardial infarction,the combined use of biomarkers such as CK-MB,MYO,and cTnI significantly enhances diagnostic accuracy and efficiency.This provides more comprehensive and reliable information for clinical decision-making and is worth promoting and applying.
