Authors' conclusion

In a high-income European country with a fully implemented pPCI strategy, 1-year mortality in pPCI-treated patients with STEMI decreased substantially between 2003 and 2018. Approximately three-quarters of the absolute mortality reduction occurred within the first 30 days after pPCI.
