The value of Copeptin, myocardial fatty acid-binding protein and myocardial markers in the early diagnosis of acute myocardial infarction.

Abstract

OBJECTIVE:

To evaluate and detect the value of Copeptin, myocardial fatty acid binding protein (H-FABP) and myocardial markers in the early diagnosis of acute myocardial infarction (AMI).

METHOD:

A retrospective analysis was carried out in 153 patients with chest pain who came to Xianyang Hospital of Yan'an University from August 2019 to April 2022, of whom 87 patients were finally diagnosed with AMI. Cardiac troponin I (cTnI), Copeptin, and H-FABP levels were measured immediately at the patient's visit. Receiver operating characteristic (ROC) curve was drawn to evaluate and compare the value of Copeptin, H-FABP and cTnI in early diagnosis of AMI and their joint effect in improving the accuracy of early diagnosis of AMI.

RESULTS:

(1) The levels of Copeptin, H-FABP and cTnI in AMI patients were evidently higher than those in non-AMI patients with chest pain. (2) The diagnostic sensitivity and specificity of Copeptin were 82.89% and 64.37%, respectively. Those of cTnI were 78.95% and 64.37% respectively, and those of H-FABP were 85.53% and 75.86%, respectively. The AUC size under the ROC curve was H-FABP > hopeptin > cTnI. (3) Joint detection of Copeptin, H-FABP and cTnI was better than mono-detection in early diagnosis of AMI.

CONCLUSION:

H-FABP has high accuracy in detecting early AMI, which is better than cTnI and Copeptin, but the joint detection of the three is of the highest value.
