The Diagnostic Value of Serum GDF15 and hs-CTnT in Elderly Patients with Acute Myocardial Infarction

Objective. To analyze the diagnostic value of serum growth differentiation factor 15 (GDFl5) and high-sensitivity troponin T (hs-cTnT) in elderly acute myocardial infarction (AMI). Methods. A retrospective analysis of 165 patients with acute chest pain admitted to the Department of Cardiology in our hospital from January to December 2020, Among them, 76 AMI patients (AMI group), 89 non-AMI patients (non-AMI group), and 80 healthy people were selected as the control group during the same period. Compare the three groups of serum GDF15, hs-CTnT levels, and left ventricular ejection fraction (LVEF) parallel correlation analysis, and draw the receiver operating curve (ROC) of serum GDF15 and hs-CTnT levels to diagnose AMI. Results. The serum GDF15 and hs-CTnT levels of the AMI group were significantly higher than those of the non-AMI group and the control group, and the difference was statistically significant (p
