Acute Myocarditis Following the Third Dose of SARS-CoV-2 Vaccine; A Case Report

Abstract BackgroundCOVID-19 pandemic has led to the development and use of the SARS-CoV-2 vaccine. In this study, we report a case with a history of multiple sclerosis that experienced acute Myocarditis following the third dose of the SARS-CoV-2 vaccine. Case presentation A 20-year-old man with a history of multiple sclerosis was admitted to the hospital to visit due to recent retrosternal chest pain four days after the third dose of SARS-COV-2 vaccine (AstraZeneca vaccine). Initial electrocardiogram showed ST-Segment elevation in the inferior limb and precordial leads. However, Echocardiography was normal without any wall motion abnormality. Cardiac Magnetic Resonance (CMR) confirmed acute myocarditis. After treatment and monitoring, Echocardiography, cardiac troponin, CBC, ESR, and CRP were normal, without any symptoms two weeks later. ConclusionsConsequently, vaccine-associated myocardial damage should be considered in the differential diagnosis in patients who have recently been vaccinated against COVID-19. Individuals with chest pain should be monitored regardless of their age and encouraged to perform relevant tests and at least an electrocardiogram.
