Peer Review Process and Criteria

This section provides a brief overview of the peer review process at The Heart Matrix (THM)


1. Review criteria


Manuscripts are evaluated according to the following criteria: 


  • the material is original and timely

  • the manuscript is written clearly and in accordance with the guidelines for authors

  • appropriate study methods have been used

  • the data are valid

  • the conclusions are reasonable and well supported by the data

  • the information contained in the manuscript is important, topical, and medically relevant.


2. Peer review mode


THM uses single-blind peer review, which means the identity of the peer reviewer is kept confidential, but the author’s identity is made known to the reviewer.


Normally, every manuscript is reviewed by at least two reviewers. However, sometimes the opinions of more reviewers are sought. Peer reviewers are selected based on their expertise and ability to provide high quality, constructive, and fair reviews. For research manuscripts, the editors may, in addition, seek the opinion of a statistical reviewer.


The existence of a manuscript under review should not be revealed to anyone other than the peer reviewers and editorial staff. Peer reviewers are required to maintain confidentiality in relation to the manuscripts they review and must not divulge any information about a specific manuscript or its content to any third party without prior permission from the journal’s editors.


Information from submitted manuscripts may be systematically collected and analyzed to help improve the quality of the editorial or peer-review processes. Identifying information remains confidential. Final decisions regarding the publication of manuscripts are made by the Editorial Office.


3. Provenance and peer review


THM is committed to transparency. Commissioned articles or articles that undergo rapid communication (fast-track review) will be published with a description of their provenance (i.e., commission or reasons for rapid communication) and how the review was organized (i.e., with or without external peer review). For articles published without external peer review (usually non-research articles, e.g., editorials, interviews, or other editorial materials), the reviews are completed directly by the editors.


4. Transparent peer review


With a commitment to openness and accountability, and to increase the level of transparency throughout our peer review process, THM has implemented a transparent peer review process.


5. Online review system


To ensure the most convenient and efficient peer review process possible, our peer reviews are conducted electronically via the Editorial Manager submission system,  which can be accessed through the journal’s website (

  • Assigned Editors pass the submitted manuscript to the Editor-in-Chief.

  • Depending on the topic of the submitted manuscript, the Editor-in-Chief passes the article to the Section Editors or an Editorial Board member with related expertise.

  • The assigned Section Editors/Editorial Board members with related expertise review the manuscript or recommend external reviewers to the Editorial Office. A literature search may be conducted to identify appropriate external experts.

  • External experts review the manuscript.

  • The external experts make recommendations.

  • The recommendations are sent to the Editor-in-Chief, along with a review from the assigned Section Editor and member of the Editorial Board.

  • The Editor-in-Chief makes a decision on the manuscript, for which there are four options: accept, minor revision, major revision, or reject.



Generally, all research articles, reviews and clinical case-based articles should undergo the standard peer review process, as outlined above. However, if an article is approved for the Rapid Communication Pathway, it will undergo a rapid review process, facilitated by previous peer review comments and revisions obtained after rejection from another esteemed journal. In such cases, there will be a “Provenance and Peer Review” statement in the footnote of the article.


To assure impartial decision-making and to avoid any potential conflicts of interest, authors with a position in the journal’s editorial team will be excluded from any editorial handling of their manuscript (including reviewing, editing, and the final decision). Articles from the Editor-in-Chief will be assigned to a Section Editor or, in cases where the Section Editor is not available, to an Editorial Board Member with related expertise. After the review comments have been received from external reviewers, the manuscript will be returned to the Section Editor or Editorial Board Member to make a final decision.


Note: Original Articles are listed as priority
