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 ...
Cardiac markers are used for the diagnosis and risk stratification of patients with chest pain and suspected acute coronary syndrome and for management and prognosis in patients with diseases like acute heart failure. Most of the early markers identified were enzymes, and as a result, the term "cardiac enzymes" is sometimes used. However, not ...
Among patients with HIV, myocarditis is the most common cardiac pathological finding at autopsy, with a prevalence of 50% or more. [59] Myocarditis is the third most common cause of death among young adults with a cumulative incidence rate globally of 1.5 cases per 100,000 persons annually. [57]
Eosinophilic myocarditis is often viewed as a disorder that has three progressive stages. The first stage of eosinophilic myocarditis involves acute inflammation and cardiac cell necrosis (i.e. areas of dead cells); it is dominated by symptoms characterized as the acute coronary syndrome such as angina, heart attack and/or congestive heart failure.
Viral-induced dilated cardiomyopathy can be characterized using different methods. A 2011 study showed in coxsackievirus infected heart proteome, increased levels of fibrotic extracellular matrix proteins and reduced amounts of energy-producing enzymes can be observed suggesting they could be characteristic in enteroviral cardiomyopathy.

Now, the markers most widely used in detection of MI are MB subtype of the enzyme creatine kinase and cardiac troponins T and I as they are more specific for myocardial injury. The cardiac troponins T and I which are released within 4–6 hours of an attack of MI and remain elevated for up to 2 weeks, have nearly complete tissue specificity and ...
A person who recently had a myocardial infarction has areas of damaged heart muscle and elevated cardiac troponin levels in the blood. [15] This can also occur in people with coronary vasospasm, a type of myocardial infarction involving severe constriction of the cardiac blood vessels. After a myocardial infarction troponins may remain high for ...
A review that considered berberine’s effects on heart health found some studies supporting this claim, but due high risk of bias, the researchers recommended more clinical trials be performed.
