Role Of Cardiac Biomarkers In Covid-19: What Recent Investigations Tell Us?

Purpose of review: Although the respiratory system is the main target of severe acute respiratory syn-drome coronavirus 2 (SARS-CoV-2), it is evident from recent data that other systems, especially cardiovascular and hematological, are also significantly affected. In fact, in severe form, COVID-19 causes a systemic illness with widespread inflammation and cytokine flood, resulting in severe cardiovascular injury. Therefore, we reviewed cardiac injury biomarkers' role in various cardiovascu-lar complications of COVID 19 in recent studies. Recent findings: Cardiac injury biomarkers were elevated in most of the complicated cases of COVID-19, and their elevation is directly proportional to the worst outcome. Evaluation of cardiac biomarkers with markers of other organ damage gives a more reliable tool for case fatalities and future outcome. Summary: Significant association of cardiac biomarkers in COVID-19 cases helps disease management and prognosis, especially in severely ill patients. (Curr Probl Cardiol 2021;46:100842.)
