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.
