“Cardiovascular effects were found in 29.24% of patients, ranging from tachycardia, palpitation, and myopericarditis.

Article: Myopericarditis was confirmed in one patient after vaccination. Two patients had suspected pericarditis and four patients had suspected subclinical myocarditis. Conclusion: Cardiovascular effects in adolescents after BNT162b2 mRNA COVID-19 vaccination included tachycardia, palpitation, and myocarditis. The clinical presentation of myopericarditis after vaccination was usually mild, with all cases fully recovering within 14 days.
The perpetual contrarian chimes in to spout his brilliance…
The study also concludes that "the incidence of COVID-19-associated cardiac injury or myocarditis is much higher, estimated to be 100 times higher than mRNA COVID-19-related myocarditis [24,25]. Moreover, mRNA vaccine-related myocarditis is characterized by overall mild presentation and favorable outcomes."
Also, the study did not utilize control groups such as one or more groups of similar size, age, demographics, and medical history, including control groups who were unvaccinated/Covid negative and/or unvaccinated/Covid positive. I would also like to know incidence of cardiovascular events following vaccinations.
