Myocardial injury due to covid-19 expressed through biomarkers and echocardiographic parameters: an integrative review of the literature

The high risk of cardiovascular complications during and after infection with SARS-CoV-2, a virus that causes COVID-19, is well documented in the world literature. Through cardiac changes, the role of echocardiography and biomarkers of myocardial injury is exalted as useful tools that can affect the morbidity and mortality of these patients. For a better understanding of the subject, an integrative review was performed from bibliographic data arranged in indexed databases. The objective of this study was to answer the following question: What is the role of biomarkers, conventional echocardiography and the Speckle Tracking analysis by the occurrence of myocardial injury caused by the SARS-CoV-2 virus? We concluded with the analysis of 10 studies eligible for the review that there is an intimate relationship between troponin and brainnatriureticpeptide with echocardiographic findings of myocardial injury by COVID-19. Moreover, these biomarkers were easy and widely available for screening patients eligible for echocardiography. Therefore, more studies are necessary to assess the validity and consolidation of this simple screening method that can predict cardiovascular complications in advance, often fatal.
