Methods
We studied a large prospective US Medicare population over an 8-month
period starting April 1 2020 to determine their effects on potential new
COVID-19 cases and subsequently, the incidence of new onset AF. The
co-morbid history was gathered for two-year period prior to the start of
the study and consisted of common cardiovascular and non-cardiovascular
multi-morbidities. The Medicare population consisted of individuals aged
65 years and above and a smaller percentage with disability in the equal
to or above the age of 18 years.
