Transition from CK-MB to troponin did not improve the 1 year mortality of non-ST elevation acute coronary syndromes.
To examine the hypothesis that transition from creatine kinase MB subunits (CK-MB) to troponin as a more sensitive biomarker of myocardial necrosis reduced the 1 year mortality of non-ST elevation acute coronary syndrome (ACS) patients. ⋯ Transition to troponin as a diagnostic marker of MI led to an increase in the incidence of non-ST elevation MI. This transition was not associated with a decrease in the 1 year non-ST elevation ACS mortality rate.
