Abstract

The novel coronavirus SARS-CoV-2 causes the disease COVID-19, a severe acute respiratory syndrome. COVID-19 is now a global pandemic and public health emergency due to rapid human-to-human transmission. The impact is far-reaching, with enforced social distancing and isolation, detrimental effects on individual physical activity and mental wellbeing, education in the young and economic impact to business. Whilst most COVID-19 patients demonstrate mild-to-moderate symptoms, those with severe disease progression are at a higher risk of mortality. As more is learnt about this novel disease, it is becoming evident that comorbid cardiovascular disease is associated with a greater severity and increased mortality. Many patients positive for COVID-19 demonstrate increased concentrations of cardiac troponin, creating confusion in clinical interpretation. While myocardial infarction is associated with acute infectious respiratory disease, the majority of COVID-19 patients demonstrate stable cTn rather than the dynamically changing values indicative of an acute coronary syndrome. Although full understanding of the mechanism of cTn release in COVID-19 is currently lacking, this mini-review assesses the limited published literature with a view to offering insight to pathophysiological mechanisms and reported treatment regimens.
