Marcadores bioquímicos do infarto agudo do miocárdio

Abstract

The acute myocardial infarction is nowadays, the main cause for cardiovascular pathologies. Developed by genetic, alimentary and behavioral factors, the AMI leads to the obstruction of the coronary blood-flow, which can lead the patient to have complications and even to die. Through the studies based on significant bibliographies, we attempted to comprehend what are the fundamental biochemical markers for the diagnosis, their changes and the main areas affected in the suggested pathologic case. The identification by electrocardiogram and the dosage of the biomarkers as: Myoglobin, CK-Total, CK-MB and Troponin is essential, being a biochemical expression of the fiber lesion, together with them, the Lactate Dehydrogenase, B-type natriuretic peptide and the reactice C protein act in the prognosis, providing a prevention for future cases. In the carried research, it is noticeable the importance of the markers and how they act in a particular region, jointly with the ECG to support the diagnosis, however it is not possible to specify the type and the dimension of the injured area, then a better investigation by the medical staff is required.
