Background: The incidence of acute myocarditis as a sub-acute side effect after vaccination with an mRNA- based vaccine against Coronavirus Disease 2019 (COVID-19) in elderly patients with cardiac dysfunction is unknown. This study assessed adverse cardiac events following vaccination. Methods: This observational study evaluated all- cause mortality and deterioration of heart failure in 100 Japanese patients who underwent vaccination with an mRNA-based vaccine against COVID-19. Heart failure status was assessed using the Brain Natriuretic Peptide (BNP) ratio, for which the BNP or N Terminal (NT)-pro BNP values were divided by their Upper Normal Limits (UNL). Deterioration was assessed based on changes in the BNP ratio; values (i.e., post-BNP levels minus pre-BNP levels) ≥ 10-fold higher than the UNL denoted significant increment. .. Read More»
