Abstract
Objective: To analyze the most effective and requested cardiac biomarkers for the diagnosis of AMI. Methods: This is a bibliographical review, which used articles and scientific research in a database such as Scielo, Lilacs and other virtual libraries. The inclusion criteria adopted were publications that had access to the text in its entirety; that the abstract is related to the proposed objective; publications in all languages; and whose year of publication does not exceed 12 years. Results: Of the 15 publications used, 12 are literature review, 1 case study, 1 clinical trial and 1 cross-sectional study. The publications used concluded the use of biomarkers as an efficient practice in the diagnosis and prognosis of cardiovascular diseases. Conclusion: Given the specificity, sensitivity and profile of release in the bloodstream, it was concluded that Myoglobin and the MB fraction of creatine kinase (CK-MB) have low specificity for are present in both the skeletal musculature and cardiac musculature but are considered sensitive. Differently from cardiac and I cardiac troponins, which show greater specificity for the heart and high clinical sensitivity.
