[Diagnostic and prognostic biomarkers in acute coronary syndrome]

Acute myocardial infarction (AMI) is an important cause of mortality and morbidity worldwide. Early diagnostics of this disease helps in the appropriate treatment of patients. Great attention is paid to the diagnostic and risk stratification of patients according to circulating biomarkers. There are a lot of scientific publications describing this topic. The aim of this article is to provide a comprehensive overview of the most important and most examined biomarkers in acute coronary syndrome. Meanwhile troponin takes a fundamental place for AMI diagnostic (mostly the high-sensitive methods) in preference to MB-fraction of creatine kinase and myoglobin. The connection to a higher sudden death risk, reinfarcts and heart failure occurring was also proved by many other biomarkers. The most important of them are the natriuretic peptides, the C-reactive protein, the heart fatty acid binding protein, the pregnancy-associated plasma protein-A, CD146, cystatin C, NGAL, copeptin, MR-proadrenomedullin, and the growth differentiation factor-15. More prospective randomized studies are needed for the further use of these other biomarkers in clinical practice.Key words: acute coronary syndrome - biomarkers.
