Cardiac troponin I (cTnI) is the most specific and sensitive biomarker in the diagnosis of myocardial injury and necrosis. CTnI increased at 412 h and maintained at 410 d after myocardial injury. CTnI entered the blood stream with irreversible ischemia my

Creatine kinase (CK) is a dimer enzyme with four different forms: mitochondrial isoenzyme and cytosolic isoenzyme CK-MM (muscle type), CK-BB (brain type) and CK-MB. The value of CK-MB in serum is an important index to diagnose myocardial ischemia

Myoglobin is a kind of protein existing in the cytoplasm of myocardium and skeletal muscle. It transports oxygen to muscle cells and can also serve as an oxygen storage capsule. The molecular weight of myoglobin is 17.8kd, so it can enter the blood circul

N-terminal brain natriuretic peptide precursor (NT-proBNP) is an inactive N-terminal fragment of BNP prohormone (proBNP) after division, which is mainly secreted by the left ventricle when cardiomyocytes are subjected to increased volume load and pressure

D-Dimer is a specific degradation product of fibrin monomer crosslinked by activator XIII and then hydrolyzed by plasmin. It is a specific marker of fibrinolysis process.Among fibrinolytic protein degradation products, only D-dimer cross-linked fragments

Myeloperoxidase (MPO) is a heme-cofactor-containing leukocyte enzyme secreted by neutrophils, monocytes, and macrophages of certain tissues, which is activated and releases MPO when subjected to inflammation or oxidative stress.

Heart-type fatty acid binding protein (H-FABP) is a small molecule protein with a molecular weight of 1400015000, which is specifically present in the cytoplasm of cardiomyocytes and is abundant in content, because cardiomyocytes are highly sensitive to i
