Retrospective cohort study examines AMI incidence and mortality during and after COVID-19 in Medicare beneficiaries, suggesting varying impacts by urbanicity.
In this retrospective cohort study of fee-for-service Medicare beneficiaries, the incidence of AMI decreased during and after the pandemic. Beneficiaries experienced greater in-hospital and 90-day mortality during the pandemic. After the pandemic, in-hospital and 90-day mortality returned to baseline among micropolitan and rural beneficiaries and was lower than baseline among urban beneficiaries.
