AACC Announces Webinar 'CK-MB: Re-Evaluating Its Role In The Clinical Lab

Washington, DC - April 12, 2011        The American Association for Clinical Chemistry (AACC) announces a webinar CK-MB: Re-evaluating its Role in the Clinical Lab to be held on May 3, 2011 at 2:00pm Eastern. The webinar will last 60 minutes.

In 2000, the European Society of Cardiology (ESC) and the American College of Cardiology (ACC) issued a consensus document which redefined myocardial infarction (MI). Prior to this redefinition, the MI label was reserved for individuals who had a major occlusive cardiac event, but the redefinition said that any amount of myocardial necrosis—even if caused by non-occlusive ischemia—should be diagnosed as an infarct. Furthermore, the joint document explicitly stated that increased concentrations of cardiac biomarkers, particularly troponin, are diagnostic for MI in the clinical setting of acute ischemia. The guidelines emphasized the role of troponin, and in fact set up troponin as the new gold standard for diagnosing AMI. The question asked in thousands of clinical laboratories was what to do with the old gold standard, CK-MB.  More than a decade since the landmark ESC/ACC recommendations, the question remains.

Most labs have now uncoupled CK-MB from their cardiac panels in favor of troponin, but the occasional request still comes in. How are labs handling CK-MB these days?  Are there settings where CK-MB may be warranted as part of the cardiac/MI panel? Does CK-MB still have a valid role in interventional cardiology?  The webinar’s expert panel - Robert H. Christenson, PhD, DABCC, FACB, Director of Clinical Chemistry Laboratories & Professor of Pathology and Medical and Research Technology, University of Maryland Medical Center in Baltimore, MD, and Robert L. Jesse, MD, PhD, Chief Consultant – Cardiology, Department of Veterans’ Affairs in Washington, DC - will address these and other questions.

AACC invites journalists reporting on the diagnosis of heart disease to attend this important and timely webinar. For a complimentary press registration, complete and submit a Press Registration Form. For more information about the webinar or AACC, contact Peter Patterson on either of the above phone numbers or at ppatterson@aacc.org.
