Cardiac Markers
What is meant by cardiac markers?
Cardiac markers are measurable biochemical substances in the bloodstream that evaluate heart function.
They have high diagnostic sensitivity and can be useful in the diagnosis, evaluation and monitoring of heart diseases.
What do cardiac markers indicate?
The measurement of cardiac markers in the patient’s blood can indicate myocardial damage or cardiovascular system dysfunctions.
The specific diagnostic tests evaluate the risk of serious cardiovascular diseases, such as coronary heart disease, myocardial infarction, ischemic stroke, or heart failure.
What biomarkers do blood tests for heart disease include?
Blood tests for heart diseases include the measurement of the following biomarkers:
- Troponins T and I (TnT / TnI): Biomarkers of high sensitivity and specificity for myocardial lesions.
- Creatine kinase-MB (CK-MB): Sensitive biomarker of myocardial necrosis.
- Natriuretic peptides (BNP and pro-BNP): Prognostic markers in heart failure and markers for the evaluation of symptoms of cardiac etiology.
- Myoglobin: Complementary biomarker of low specialty, but high sensitivity, for the diagnosis of acute myocardial infarction.
- Homocysteine (Hcy): Independent risk biomarker for coronary cerebral and peripheral vascular diseases.
- High-sensitivity C-reactive protein (hs-CRP): Complementary biomarker of high sensitivity for inflammations, which can be used as a risk indicator for coronary heart disease.
- Fibrinogen: Coagulation factor responsible for normal blood clotting. It acts as a risk indicator for blood clot formation.
- Lipoprotein-associated phospholipase A2 (PLAC test): Biomarker for inflammation in the blood vessels, which is linked to an increase of plaque in the arteries.

Frequently Asked Questions
Troponin is a protein found in myocardial tissue. It is released into the bloodstream in the event of acute myocardial infarction.
Its measurement indicates whether a patient with suspicious symptoms is likely to have had a heart attack. The specific test is especially useful in cases where the electrocardiogram is not diagnostic.
Furthermore, a troponin increase happens when there is inflammation and/or necrosis of the myocardium (myocarditis, cardiomyopathy, heart failure).
