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 ...
In particular, acute myocardial infarction in the distribution of the circumflex artery is likely to produce a nondiagnostic ECG. [10] The use of additional ECG leads like right-sided leads V3R and V4R and posterior leads V7, V8, and V9 may improve sensitivity for right ventricular and posterior myocardial infarction.

A myocardial infarction (2) has occurred with blockage of a branch of the left coronary artery (1). A myocardial infarction, according to current consensus, is defined by elevated cardiac biomarkers with a rising or falling trend and at least one of the following: [82] Symptoms relating to ischemia
Troponin I is not entirely specific for myocardial damage secondary to infarction. Other causes of raised troponin I include chronic kidney failure, heart failure, subarachnoid haemorrhage and pulmonary embolus. [9] [10] In veterinary medicine, increased cTnI has been noted from myocardial damage after ionophore toxicity in cattle. [11]
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] and cardiac troponin I (cTnI), [6] [7] both of which are also markers for injury to the muscular layer of the heart. Therefore, it is imperative to also rule out acute myocardial infarction in the face of these biomarkers. The elevation of these substances may occur when inflammation of the heart's muscular layer in addition to acute ...
