Key result
COVID-19 vaccines are associated with rare cardiovascular complications such as myocarditis and thrombotic events, but the overall benefits of vaccination outweigh these risks.
Why the study?
Unheralded cardiac arrest in previously healthy young people months or years after COVID-19 vaccination highlighted an urgent need for risk stratification.
What are the cardiovascular complications associated with COVID-19 vaccines in the general population?
What are the cardiovascular complications associated with COVID-19 vaccines in the general population?
Cardiovascular complications from COVID-19 vaccines are rare, and the benefit of lower mortality from COVID-19 infection takes precedence over these undesired adverse events.
Highlights a potential mechanism for late sudden cardiac arrest post-vaccination; leaves open the.
Unheralded cardiac arrest among previously healthy young people without antecedent illness, months or years after coronavirus disease 2019 (COVID-19) vaccination, highlights the urgent need for risk stratification. The most likely underlying pathophysiology is subclinical myopericarditis and reentrant ventricular tachycardia or spontaneous ventricular fibrillation that is commonly precipitated after a surge in catecholamines during exercise or the waking hours of terminal sleep. Small patches of inflammation and/or edema can be missed on cardiac imaging and autopsy, and the heart can appear grossly normal. This paper reviews evidence linking COVID-19 vaccines to cardiac arrest where unfortunately the majority of victims have had no antecedent clinical evaluation. We propose a comprehensive strategy for evaluating cardiovascular risk post-vaccination, incorporating detailed patient history, antibody testing, and cardiac diagnostics in the best attempt to detect abnormalities before sudden cardiac death. This approach aims to identify individuals at higher risk of cardiac events after COVID-19 vaccination and guide appropriate clinical management. It is prudent for each primary care physician to have a pre-established plan when addressing this issue in their practice.

McCullough et al. (2025) conducted a review in Cardiovascular complications following COVID-19 vaccination. COVID-19 vaccines was evaluated on Incidence of cardiovascular adverse events. COVID-19 vaccines are associated with rare cardiovascular complications such as myocarditis and thrombotic events, but the overall benefits of vaccination outweigh these risks.
