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.
After a heart attack a number of different cardiac biomarkers can be measured to determine exactly when an attack occurred and how severe it was. A biomarker can be a traceable substance that is introduced into an organism as a means to examine organ function or other aspects of health. [7]
In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."
Clinical Advantages of Critical Diagnostics' Cardiac Biomarker ST2 Featured In YouTube Video Study shows ST2 combined with troponin to be superior to Roche's NT-proBNP for risk stratification of ...
Cardiac stress testing is used to determine to assess cardiac function and to disclose evidence of exertion-related cardiac hypoxia. Radionuclide testing using thallium or technetium can be used to demonstrate areas of perfusion abnormalities. With a maximal stress test the level of exercise is increased until the person's heart rate will not ...

Previous WHO criteria [7] formulated in 1979 put less emphasis on cardiac biomarkers; according to these, a patient is diagnosed with myocardial infarction if two (probable) or three (definite) of the following criteria are satisfied: Clinical history of ischaemic type chest pain lasting for more than 20 minutes; Changes in serial ECG tracings
The ST2 cardiac biomarker (also known as soluble interleukin 1 receptor-like 1) is a protein biomarker of cardiac stress encoded by the IL1RL1 gene. ST2 signals the presence and severity of adverse cardiac remodeling and tissue fibrosis, which occurs in response to myocardial infarction, acute coronary syndrome, or worsening heart failure.
