Myocardial Injury and Outcomes Following COVID-19 Vaccination (MYOVAX Study)

Coronavirus disease 2019 (COVID-19) vaccination frequently leads to minor side effects that may be more intense after the second dose, including fatigue and pain. However, there are emerging reports of more serious side effects in a minority of patients including myocarditis. Given the recent introduction of COVID-19 vaccination, there is limited understanding of: (i) prevalence and pattern of myocardial injury post vaccination, (ii) the risk factors for myocardial injury and adverse cardiac events post vaccination, and (iii) imaging and blood biomarkers for early recognition of patients at risk of adverse outcomes. This study will address the above-mentioned knowledge gaps by focusing on patients who have received at least one dose of a COVID-19 vaccine. The study will focus on cardiac blood and imaging biomarkers to facilitate early recognition of patients at risk for myocardial injury after COVID-19 vaccination. Ultimately, the intention is to identify patients at risk, reduce adverse events, and determine the need for longer-term follow-up in patients with myocardial injury after vaccination.
