title: Troponin-T as a serum marker for myocardial infarction.
abstract: We report here our experience with serum troponin T (TnT), measured with the sandwich immunoassay introduced by Boehringer Mannheim as a marker for myocardial infarction. We assayed TnT in serial serum samples from 30 patients with time courses of serum CK, CK-MB, AST, and LD that we consider typical of acute myocardial infarction (MI). In every patient but one, TnT rose in parallel with both CK-MB and AST, but remained elevated significantly longer. The ratios of the elevations of the different markers varied from patient to patient with marked variation in the ratio of TnT to CK-MB. There appeared to be a significant association between the magnitude of that ratio with the level of ALT.
