Dear Readers, Authors and Reviewers,

Thank you for your interest in Kardiologia Polska (Polish Heart Journal). Kardiologia Polska changes the publisher since May 2021. Due to the necessity to transfer the journal’s archive to the website managed by the new publisher — Via Medica, technical problems may occur for a few days. Due to the ongoing reconstruction of the website, readers who want to read full articles should go to the Archive tab and find the issue in a given year.
We apologize for any temporary inconvenience.
