Myocarditis and related complications of SARS-CoV-2 infection

Background Myocarditis and pericarditis are associated with a wide range of presentations and have received renewed interest because of the association with SARS-CoV-2 infection. Some of these complications have also been reported with the mRNA vaccines used for preventing the infection, which has caused widespread anxiety and uncertainty in the community. Objective The aim of this article is to summarise an approach to the clinical problem of myocarditis and treatment/management of patients with myocarditis in the community. This article also discusses SARS-CoV-2 infection and vaccines. Discussion Myocarditis and pericarditis need to be considered as a differential, especially in all adolescents or young adults presenting with acute chest pain, shortness of breath or palpitations. Other serious causes of chest pain – such as acute myocardial infarction, pulmonary embolism, aortic dissection and pneumothorax – also need to be excluded. Initial electrocardiography, troponin and C-reactive protein tests are recommended, and cardiology advice should be sought for all suspected cases
