Cardiac biomarkers for early diagnosis of acute myocardial infarction: a literature review

Abstract

Acute Myocardial Infarction (AMI) known as heart attack is one of the main cardiovascular pathologies in Brazil, being caused by genetic and environmental factors. Aiming at the diagnosis in the first symptoms of the disease, biomarkers have become a useful tool. Present a literature review to identify cardiac biomarkers used in the diagnosis of Acute Myocardial Infarction. This is a literature review using the descriptors "Cardiac Biomarkers", "Diagnosis" AND "Acute Myocardial Infarction" in the VHL, LILACS, PubMed and SCIELO databases. Enzymes are responsible for biological reactions, they together with proteins are used as markers for aim investigation. Creatine kinase fraction MB (CK-MB), Troponins, Myoglobin and Lactate dehydrogenase (LDH) can be cited. In view of the presented, it is identified that the use of cardiac biomarkers is indispensable for the early diagnosis of the first hours of myocardial lesions.
