The VIDAS® Acute Coronary Syndrome (ACS) panel offers three complementary tests for the assessment of myocardial injury1, 2. In combination with clinical examination and an electrocardiogram, they enable timely and accurate evaluation of patients for optimal care. Performed on the instruments of the VIDAS® family, these assays are particularly suitable for emergency testing.
Cardiac Troponin I (cTnI) is the preferred biomarker of cardiac necrosis due to its specificity for myocardial tissue damage2. A rapid increase of cTnl levels (within 3 to 6 hours after the onset of chest pain) and the fact they remain elevated for 4 to 7 days5 give cTnI high diagnostic value for myocardial infarction.
The protein concentration of the MB isoenzyme of human creatine kinase (CK-MB) is recommended for the diagnosis of myocardial infarction when cardiac troponin assays are not available5. CK-MB also increases rapidly after infarction. Due to its shorter half-life, it can be used as a marker for re-infarction.
Myoglobin is one of the first markers of myocardial damage to be measured after the onset of myocardial infarction. For patients presenting within 6 hours of the onset of symptoms, it may be considered in addition to cardiac troponin for early rule-out5.
