Cardiovascular Events After Coronavirus Disease 2019 Vaccinations: Hypersensitivity Myocarditis After Coronavirus Disease 2019 Vaccines, Diagnostic and Long-term Considerations

Abstract

To the Editor, Myocarditis is an inflammatory condition of the myocardium with absence of acute or chronic coronary artery disease. The correct terminology and distinction between myocarditis brought on by vaccinations, medications, or other substances are still up for debate. There are various forms of myocarditis 1 according to causative, histological, and clinicopathological criteria. In the interesting report published in the Anatolian Journal of Cardiology, 2 the author described a 65-yearold Russian patient who had an almost asymptomatic coronavirus disease 2019 (COVID-19) infection and a year later was vaccinated with Gam-COVID-Vac vaccination. He then experienced symptoms consistent with asthenia, dyspnea, cardiac arrhythmia, limb numbness, and herpes zoster. The author emphasized the need to be aware of potential late side effects from COVID-19 vaccinations, including cardiovascular issues.
