Summary What is already known about this topic?
Studies have found an increased risk for cardiac complications after SARS-CoV-2 infection and mRNA COVID-19 vaccination, but few have compared these risks.
What is added by this report?
Data from 40 health care systems participating in a large network found that the risk for cardiac complications was significantly higher after SARS-CoV-2 infection than after mRNA COVID-19 vaccination for both males and females in all age groups.
What are the implications for public health practice? These findings support continued use of recommended mRNA COVID-19 vaccines among all eligible persons aged ≥5 years.
