The Editor-in-Chief, on behalf of the Hypertension Research Editorial Board, greatly appreciates the generous support from peer reviewers. A total of 454 reviewers kindly reviewed the manuscripts submitted from January to December 2021. In appreciation of their valuable contributions, we have selected the 20 Best Reviewers of 2021. These individuals were elected simply based on the number of reviews that they completed. The number beside the reviewer’s name indicates the number of reviews of original submissions that the reviewer completed.

We express our sincere gratitude to all reviewers for their continuous support to Hypertension Research.
