Abstract

We studied a possible effect of the extent of the acute phase response after acute myocardial infarction on the cumulative release of troponin T. The height of the acute phase response might influence the cumulative release of troponin T, bound to the myofibrillar structures of the heart, in a different way compared to the free cytoplasmic cardiac marker hydroxybutyrate dehydrogenase (EC 1.1.1.27). To investigate this, the cumulative amount of C-reactive protein in plasma, i.e. the quantified acute phase response, was related to the cumulative plasma release of hydroxybutyrate dehydrogenase (an established method for infarct sizing) on the one hand and to that of troponin T on the other hand.

The study was performed in patients receiving (n=16) and in patients not receiving (n=6) thrombolytic therapy. Cumulative protein release was calculated using a two-compartment model for circulating proteins.

Conclusions: The cumulative amount of plasma C-reactive protein is significantly higher in the patients not receiving thrombolytic therapy, as is in accordance with earlier studies. The cumulative amount of troponin T released is significantly related to the cumulated concentration of C-reactive protein, especially in patients not receiving thrombolytic therapy. The intensity of the acute phase response, estimated from cumulative plasma C-reactive protein response, has no effect on the relative proportions of troponin T and hydroxybutyrate dehydrogenase released into plasma.
