Cardiac markers are biomarkers measured to evaluate heart function. They can be useful in the early prediction or diagnosis of disease. [1] Although they are often discussed in the context of myocardial infarction, other conditions can lead to an elevation in cardiac marker level. [2] [3]
The CPK-MB test (creatine phosphokinase-MB), also known as CK-MB test, is a cardiac marker [3] used to assist diagnoses of an acute myocardial infarction, myocardial ischemia, or myocarditis. It measures the blood level of CK-MB (creatine kinase myocardial band), the bound combination of two variants (isoenzymes CKM and CKB ) of the enzyme ...
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...
Elevated troponin levels are prognostically important in many of the conditions in which they are used for diagnosis. [36] In a community-based cohort study indicating the importance of silent cardiac damage, troponin I has been shown to predict mortality and first coronary heart disease event in men free from cardiovascular disease at baseline ...
The level of the troponin, as well as a change over time, are useful in measuring and diagnosing or excluding myocardial infarctions, and the diagnostic accuracy of troponin testing is improving over time. [72] One high-sensitivity cardiac troponin can rule out a heart attack as long as the ECG is normal. [83] [84]
Acute coronary syndrome is subdivided in three scenarios depending primarily on the presence of electrocardiogram (ECG) changes and blood test results (a change in cardiac biomarkers such as troponin levels): [4] ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), or unstable angina. [5]
Individuals who develop cardiac chest pain are generally treated empirically as an "acute coronary syndrome", and are immediately tested for elevations in their blood levels of enzymes such as creatine kinase isoenzymes or troponin that are markers for cardiac damage.
Cardiac enzymes are usually negative and are moderate at worst, and cardiac catheterization usually shows absence of significant coronary artery disease. [ 1 ] The diagnosis is made by the pathognomonic wall motion abnormalities, in which the base of the left ventricle is contracting normally or is hyperkinetic while the remainder of the left ...
