Abstract:
Cardiac troponin (cTn) is a cardiomyocyte-specific protein detectable in the blood stream upon cardiac injury and is the recommended biochemical marker to diagnose myocardial infarction (MI). In the emergency department (ED), troponin levels in patient blood samples are quantified using commercially available assays. Troponin testing plays a vital role in the differentiation of MI from alternate causes of acute coronary syndrome (ACS). Patients presenting in the ED with chest pain, referred pain, nausea, vomiting, dyspnea or other symptoms of ACS require a troponin measurement. This measurement allows differentiation between unstable angina (UA) and non-ST segment elevation MI (NSTEMI) if electrocardiogram (ECG) has ruled out ST segment elevation MI (STEMI). Commercially available troponin tests are specific to either troponin T or troponin I and are high sensitivity or conventionally sensitive. Guidelines suggest that optimal use of these different troponin assays is critical for timely diagnosis of life threatening cardiac conditions in patients presenting with symptoms of ACS. The purpose of this report is to retrieve and review the existing guidelines on optimal use of the available cardiac troponin assays for evaluation of patients presenting ACS symptoms in the emergency department.
