Each year in the US alone, over one million individuals are diagnosed with an acute myocardial infarction (AMI) and approximately one half of these have had an AMI in the past. However, as many as 1 - 5% of patients with an AMI are misdiagnosed in the emergency department and are discharged. Rapid diagnosis of acute myocardial infarction is vital and laboratory testing that is sensitive and specific is essential. Upon completion of this course, you will be able to identify the characteristics of an optimal cardiac biomarker and discuss the laboratory tests that are most useful for rapid diagnosis and monitoring of ischemic heart disease and heart failure.

Objectives

  • Describe the role of cardiac biomarkers, the characteristics of a good marker of cardiac disease, and the use of cardiac biomarkers today.
  • Explain atherosclerosis as an inflammatory process.
  • Compare and contrast the cardiac biomarkers cTnI and cTnT.
  • Discuss the utilization of CK-MB, myoglobin, and CK-isoform measurement in diagnosis of an acute myocardial infarction.
  • Describe the formation of BNP and NT-proBNP and their role as markers of congestive heart failure.
  • Interpret the measurement results of cardiac biomarker assays in the diagnosis of an acute myocardial infarction and congestive heart failure.
  • Explain the role of cardiac biomarkers in risk stratification of those with heart disease.
