Aim and editorial policy

Arquivos Brasileiros de Cardiologia (Arq Bras Cardiol), the journal of the Brazilian Society of Cardiology, publishes articles on cardiovascular topics, after review by its Editorial Board. Arquivos Brasileiros de Cardiologia is a monthly publication, indexed in the Cumulated Index Medicus, National Library of Medicine, Bethesda, Maryland, USA. By submitting a manuscript, the authors are indicating that the work has not been published, simultaneously submitted, or accepted for publication by any other journal. All authors must have read and approved the manuscript and be able to defend its contents. When a manuscript is accepted for publication, it becomes the sole property of the Brazilian Society of Cardiology, and no part of it may be used without written permission from the Society.

Only those manuscripts prepared in strict accordance with the rules specified below will be referred to the Editorial Board.


Preparation of originals


1. The Brazilian Archives of Cardiology (Arq Bras Cardiol) is a monthly publication of the Brazilian Society of Cardiology, indexed in the Cumulated Index Medicus of the National Library of Medicine and the MEDLINE, EMBASE, LILACS, Scopus and SciELO databases, with PubMed (United States National Library of Medicine) citation in English and Portuguese.

2. By submitting a manuscript, the authors must certify that the work has not been previously published or is being considered for publication elsewhere. All scientific contributions are reviewed by the Editor-in-Chief, the Editorial Advisor, Associate Editors and the Members of the Editorial Board. Only articles that strictly comply with the specified guidelines will be sent to reviewers. Manuscripts will also undergo statistical review, as necessary. Acceptance is contingent upon originality, significance and scientific contribution to knowledge in the field.

3. Sections

3.1. Editorial: All Editorials are written by invitation. Spontaneously submitted editorials will not be accepted.

3.2. Letter to the Editor: correspondence of scientific content related to articles published in the previous two months will be evaluated for publication. The authors of the quoted original article will be invited to respond.

3.3. Original Articles: the journal accepts all kinds of original research in the cardiovascular field, including research in humans and experimental research.

3.4. Review Articles: editors invite authors to write most reviews. However, high-quality review articles, by authors or groups with a history of publications in the field are welcome. Only articles written by authors with a broad academic curriculum or publication experience will be accepted, as verified by the Lattes system (CNPQ), Pubmed or SCIELO. Occasionally, spontaneously submitted reviews may be reclassified as "Clinical Update" and published on the journal's web site (see below). 3.5. Brief Communication: original experiences, of which relevance to the theme justifies the presentation of initial data from small series or partial data from clinical trials, will be accepted for review.

3.6. Anatomo-Clinical Correlation: presentation of a clinical case and discussion of topics of interest related to clinical, laboratory and anatomopathological content. 3.7. Clinical-Radiographic Correlation: presentation of a congenital heart disease case, emphasizing the importance of radiographic and/or clinical elements for subsequent correlation with other tests, which will confirm the diagnosis, thus justifying the conduct.

3.8. Clinical Update: this section aims to focus on themes of clinical interest, but with more limited impact potential. High-quality articles, performed by authors or groups with a history of publications in the area will be accepted for review.

3.9. Case Report: cases that include original descriptions of clinical observations or that represent originality of a diagnosis or treatment, or depict uncommon situations in clinical practice, and deserve greater understanding and attention from cardiologists will be accepted for review.

3.10. Cardiovascular Image: clinical or basic research images, or of complementary examinations that depict interesting aspects of imaging methods, clarify cardiovascular disease mechanisms and highlight relevant points of physiopathology, diagnosis, or treatment will be considered for publication.

3.11. Point of View: it presents the authors’ position or opinion on a specific scientific topic. This position or opinion should be adequately substantiated in literature or on their personal experience, aspects that will be the basis for the opinion to be given.

15.11. Statistical guidelines

15.11.1. The appropriate use of statistical methods, as well as their correct description, is of utmost importance to have your article published at the Brazilian Archives of Cardiology (Arquivos Brasileiros de Cardiologia). Thus, the following general guidelines are presented to the authors on the information that must be provided in the article regarding the statistical analysis (for details, please read the statistical guidelines of the European Heart Journal).

1) About the sample:

  • Provide details on both the population of interest and the procedures used to define the study sample.

2) In the Methods section, create a subsection exclusively dedicated to the description of the statistical analysis performed in the study, including:

  • Presentation of continuous and/ or categorical variables: for continuous variables with normal distribution, mean and standard deviation should be used, whereas median and interquartile ranges should be used with those with non-normal distribution. As for categorical variables, they must be depicted as absolute numbers and percentages, with the respective confidence intervals;
  • Description of the statistical methods used. When using more complex statistical methods, a literature reference must be provided for such methods;
  • As a rule, statistical tests should always be two-sided, instead of one-sided;
  • Level of statistical significance used; and
  • Specification of the software used in the statistical analysis and its respective version.

3) Regarding the presentation of results after the statistical analysis:

  • The main results should always be described with their respective confidence intervals;
  • Do not repeat in the manuscript body data that have already been depicted in tables and figures;
  • Rather than having very large tables, use charts alternatively to facilitate reading and understanding of the content;
  • At the tables, even if the p value is non-significant, provide its respective value instead of "NS" (e.g., p = 0.29 instead of NS).
