Utilization of Biochemical Markers in Acute Coronary

of cardiac markers in coronary artery diseases were published in July 1999 (1). Since production of this initial document, numerous published studies and presented data have added significantly to the knowledge base for biochemical markers of cardiac injury. This increased knowledge has substantially expanded the scope of rec-ommendations for biochemical marker utilization since the 1999 document, and in particular has required the inclusion of recommendations regarding biochemical markers that extend beyond myocardial necrosis. Toward addressing these advances and their impact on biochem-ical marker utilization in clinical practice, the NACB appointed a chair and members of an LMPG committee that was charged with revising and extending the earlier recommendations by establishing modern guidelines fo
