Acute Myocardial Injury Following COVID-19 Vaccination

Dear Editor,

We would like to share ideas on “Acute Myocardial Injury Following COVID-19 Vaccination: A Case Report and Review of Current Evidence from Vaccine Adverse Events Reporting System Database. ¹ ” Deb et al mentioned that “Review of the Vaccine Adverse Events Reporting System (VAERS) in the Centers for Disease Control and Prevention . . .. . .. . . be vigilant about the possibility of new adverse events. ¹ ” The myocardial injury following vaccination is sporadically reported and it might be underreported since self-limitation is possible. ² Regarding the reported elderly case, ¹ there are many possible underlying pathomechanism. Deb et al noted that it was a result of an acute immune response but there is no data on immune change or pathological autoimmunity. In this case, there might be an underlying cardiovascular condition and the given vaccine might induce thrombohemostasis alteration. In a previous report, the COVID-19 vaccination can result in increased blood viscosity which might be an important leading cause of myocardial disease. ³
