Cardiac markers are usually measured in blood serum and their concentrations can help doctors assess the severity of heart problems and choose the best treatment strategy. An increase in these markers in the blood can indicate acute or chronic cardiovascular disease, allowing for a quick and accurate diagnosis. Here are some important cardiac markers:

Troponin:

Troponin is one of the most important markers of heart damage. It is a protein found in the heart muscle. When heart cells are damaged, troponin is released into the blood. Troponin tests are very sensitive and specific for heart attacks.

BNP (Brain Natriuretic Peptide) and NT-proBNP:

BNP is produced by the heart, especially when the heart muscle is overloaded, as is the case with heart failure. The measurement of BNP or NT-proBNP in the blood can indicate heart failure.

D-dimer:

D-dimer is a marker for activation of the coagulation system and may indicate thrombosis or embolism. In some cases, heart attacks can be associated with thrombosis.
