Purpose COVID 19 has also been associated with myocardial inflammation and subsequent myocardial injury 2. The development and emergency approval of novel mRNA vaccines to combat this disease has also brought about its own set of challenges. As more and more people are vaccinated, cases of adverse events likewise continue to grow. One of the most worrisome COVID 19 vaccine related side effects  involves the cardiovascular system, with myocarditis having been documented in adolescents and young adults after receiving mRNA vaccines4....
Read more Methods and materials This is a single-center retrospective study of adult patients from The Medical City who underwent cardiac magnetic resonance imaging with findings compatible with myocarditis from March 2017 to March 2022.The sample size of 76 was divided into 45 COVID 19-related myocarditis cases and 31 cases of myocarditis from other causes. The cases of myocarditis from other causes were obtained from the pre-COVID period between March 2017 to March 2020 and the cases from COVID 19 related myocarditis were from the...
Read more Results Out of the study population of 76 patients, 45 were COVID 19-related myocarditis cases and the other 31 were cases of myocarditis from other causes. The median age of all patients was 42 (35 – 56.5) or approximately 42 years old. More than half were male patients and 40.8% were females.There was a significant difference between the cardiac magnetic resonance imaging findings in patients diagnosed with COVID 19-related myocarditis and myocarditis from other causes (P<0.05). COVID19-related cases showed statistically higher late gadolinium...
Read more Conclusion A higher percentage of patients with COVID 19-related myocarditis presented with the two main cardiac MR imaging findings for myocarditis based on the Revised Lake Louis Criteria, qualified by late gadolinium enhancement and myocardial edema. These two are markers for myocardial injury, with the presence of both giving strong evidence of myocardial inflammation. However, this study also shows that these patients exhibit significantly better cardiac functions as compared to myocarditis from other causes. Patients with COVID 19-related myocarditis exhibit higher ejection...
