Recent data suggest that SARS-CoV-2 could be a possible aetiological agent for myocarditis in the current pandemic.1 Although we have some understanding of its respiratory manifestations, limited data are available regarding the involvement of the heart with this virus.Myocarditis secondary to SARS-CoV-2 has been reported as one of the causes of increased mortality.1 The European Society of Cardiology (ESC) states ‘in the absence of vaccines or curative medical treatment, SARS-CoV-2 exerts an unprecedented global impact on public health and healthcare delivery’.2 In this article, we outline the pathophysiology, clinical manifestations, investigations and some of the treatment modalities that have been used so far for the management of SARS-CoV-2-related myocarditis. We also suggest areas for further research.Multiple case reports have described SARS-CoV-2-related myocarditis.3–5 However; there are no randomised controlled trials or meta-analysis on this subject.Proposed mechanisms for injury to the myocardium include binding of SARS-CoV-2 spike protein to ACE 2 which facilitates virus entry into the target cells,6 immune-related myocardial inflammation and direct injury to the myocardium caused by hypoxemia.7 Furthermore, it has also been suggested that IL-6 plays an integral role in activation of helper T cells, which in turn release inflammatory cytokines ultimately resulting in myocardial inflammation and damage.8 Age distribution and clinical presentation of SARS-CoV-2-related myocarditis is variable. Clinical manifestations can be as mild as fatigue and shortness of breath to devastating … ER -
