New Year's greeting and overview of World Journal of Cardiology in 2021

On behalf of the Editorial Office of World Journal of Cardiology (WJC), we extend our sincere gratitude to our authors, readers, Editorial Board members, and peer reviewers, thanking each and every one for their contributions to WJC in 2020 and with wishes for a Happy New Year. It was the collective support of all authors, Editorial Board members, peer reviewers and staff of the Editorial Office that allowed the Baishideng Publishing Group Inc. to carry out successfully the complete peer review, editing and publishing processes for WJC in 2020. We have now analyzed the metric data of WJC's manuscripts that were submitted and published in 2020, the peer review of manuscripts in 2020, the invited manuscripts for 2021 and the Editorial Board members’ composition and activities. As a global academic journal in cardiology, the findings from such will facilitate greater productivity and more efficient collaborative efforts to raise the academic rank of WJC in 2021. We enthusiastically anticipate WJC’s contributions to promote further cardiology research sharing and exchange in 2021.
