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 syndrome 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 cardiovascular 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.
