Authors who are not native speakers of English are strongly encouraged to use professional language-editing services prior to submission. The journal does not provide translation services. Manuscripts written in poor English will be rejected without peer review.

Plagiarism detection

All manuscripts submitted to Kardiol Pol are checked for plagiarism using Similarity Check, a service enabling the editors to screen published and submitted content for originality by providing access to the iThenticate software. Cases of suspected scientific misconduct, including plagiarism and duplicate publications, are handled according to the Committee on Publication Ethics’ Core Practices, as outlined in this flowchart (for Polish version, click here).

SUBMISSION OF MANUSCRIPTS

All manuscripts should be submitted via electronic submission system at https://ojs.kardiologiapolska.pl/kp.

First-time users must click “Register” on the navigation menu at the top of the screen and enter the required information. The system will send an automatic e-mail to the user with the username and password. Detailed guidelines are available at the editorial system site.

The author will be asked to provide information about the manuscript and attach files containing the text and any figures and tables. The system will create a PDF from the data submitted, which is the format in which the manuscript will be made available to the editors and referees during the peer-review process.

The manuscript text, references, tables, and figure legends should be prepared in a single file. Papers should be submitted as Microsoft Word documents.

Any appendices must be supplied separately and will be published as online-only supplementary data. Please use the word “Supplementary” for any references to appendices in the manuscript, e.g. Supplementary Table S1, Supplementary Appendix S2.

Tables should be included in the manuscript file and must appear at the end of the text on separate sheets (and not embedded in the text). Tables should be created using the Microsoft Word table function.

Figures should be submitted as separate files. They should be in high resolution and in one of the following formats: .tiff, .gif, or .jpg.

For selected article types, the author will be required to enter the abstract and keywords during the submission process. These may be copied and pasted from the manuscript document but must still appear in the manuscript itself.

The authors may provide the full names and e-mail addresses of two preferred referees to whom their manuscript may be sent for peer review. The names should be entered in the “Enter Comments” section during electronic manuscript submission. The authors may also provide the names of non-preferred referees and ask for their exclusion from the peer review process.

On submission, the authors should specify the category for which their manuscript is intended.

Articles should be limited to 4000 words (excluding abstract but including references and table and figure legends), up to eight figures or tables, and up to 50 references. Authors should include one unstructured paragraph on a separate page, outlining the key novel findings with their potential relevance to clinical practice or pathophysiology of cardiovascular diseases, intended for non-specialists in cardiology. The paragraph should come under the heading “What’s New?” following the title page and should have no more than 150 words.

Reviews: This category contains comprehensive reviews that summarise and critically evaluate current research in the field and identify future implications. Review articles will be solicited by the editor-in-chief. However, unsolicited reviews will be considered if they are submitted by experts in the field with a strong track record of publications indexed in PubMed. A presubmission enquiry should contain the title of the manuscript, abstract, and a list of publications for each individual author. Reviews should not exceed 5000 words (excluding abstract but including references and table and figure legends), 10 figures or tables, and 100 references.

MANUSCRIPT PREPARATION

Text

The manuscript should be typed double spaced using 2.5-cm margins all around with right margins unjustified. The Times New Roman font (12 pt) should be used in the whole manuscript, including references, tables, and figure legends, and the Symbol font for Greek or special characters. Abbreviations should be used only if necessary and if they appear at least three times in the manuscript. Please avoid providing the same data in the text and tables.

All original articles should contain the following sections: Title Page, Structured Abstract and Keywords, Introduction, Methods, Results, Discussion, Acknowledgements, References, Appendix, Tables, and Figure legends. References, figures, and tables should be numbered in the order in which they are cited in the text. The abstract (maximum 250 words) should be structured using the following headings: Background, Aims, Methods, Results, and Conclusions, followed by a list of three to five keywords. All abbreviations used in the abstract should be spelled out at first mention in the text. The number of abbreviations should be restricted to a minimum.

Generic names should be used for drugs and instruments whenever possible. The statistical analysis section is required in all original articles and short communications. Power calculation should be presented whenever necessary.

Review articles should contain the following sections: Title Page, Unstructured Abstract and Keywords, the main body of the manuscript divided preferably into sections with subtitles, Acknowledgements, References, Appendix, Tables, and Figure legends. References, figures, and tables should be numbered in the order in which they are cited in the text. Generic names should be used for drugs and instruments whenever possible.

Short communications should contain the following sections: Title Page, Introduction, Methods, Results and Discussion (combined), Acknowledgements, References, Appendix, Table, and Figure legend.

Title page

The title page should contain: (a) title, (b) name(s) of authors, (c) affiliations of all authors, (d) brief title (up to six words), (e) name of the corresponding author to whom proofs should be sent, with complete postal address, telephone and fax numbers, and e-mail, (f) conflict of interest statement.

Acknowledgements

Acknowledgements, including any support in the form of grants, equipment, or drugs, should be provided at the end of the text before References.

References

References should be identified in the text by Arabic numerals in square brackets and numbered in the order cited. They should be typed double spaced on sheets separate from the text. The modified Vancouver style should be used. Complete information should be given for each reference, including title of article, abbreviated journal title, and inclusive page numbers (in full range). If a journal is not listed in the PubMed database, its full title should be given. The first three authors should be listed, followed by et al. If a work has four authors, all names should be listed.

A few examples of articles in the proper reference style are presented below:

Feldman T, Kar S, Elmariah S, et al. EVEREST II Investigators. Randomised comparison of percutaneous repair and surgery for mitral regurgitation: five-year results of EVEREST II. J Am Coll Cardiol. 2015; 66(25): 2844–2854, doi: 10.1016/j.jacc.2015.10.018.

Marijon E, Mirabel M, Celermajer D, et al. Rheumatic heart disease. Lancet. 2012; 379(9819): 953–964, doi: 10.1016/s0140- 6736(11)61171-9.

Personal communications, manuscript in preparation, and other unpublished data that cannot be found in available databases should not be cited in the reference list but should be mentioned in the text in parentheses; the main author’s name should be provided. For articles published in languages other than English, the English translation of the title should be given, included in square brackets.

Figures

All illustrations should be referred to as figures and should be numbered in a single sequence in the order in which they are mentioned in the text. Abbreviations in figures or legends should be kept to a minimum and spelled out to make figures self-explanatory.

Submitted figures should be in high resolution and in one of the following formats: .tiff, .gif, or .jpg. The resolution required for publication is 600 dpi or more.

There is no charge for colour figures in Kardiol Pol. However, colour figures may be printed as black-and-white images unless the colour has a significant meaning and should be retained for the proper interpretation of the presented data/findings. The decision is at the discretion of the editors in consultation with the authors. The colour will be retained in the online version of the article and in supplementary materials. The colour of charts and graphs will be adapted to the journal’s style by the production team.

Tables

Tables should be typed on separate sheets in the text, with the table number (in Arabic numerals) and title above and any explanatory notes below the table. All abbreviations in tables should be spelled out in a table footnote and arranged in an alphabetical order. If the abbreviations in tables appear in two or more tables, they should be presented below the second table using a phrase: “Abbreviations: see Table 1.” Then additional abbreviations should be presented if they were absent in previous tables.

Supplementary data

Supporting material that is not essential for inclusion in the full text of the manuscript but would nevertheless benefit the reader can be made available by the publisher as online-only content, linked to the online manuscript. The material should contain data that are additional or complementary and directly relevant to the article content, for example detailed methods, extended data analysis, or additional figures.

Supplementary text and figures must be prepared as required for the full text and submitted at the same time as the main manuscript for peer review. They cannot be altered or replaced after the paper has been accepted for publication. Please indicate clearly the material intended as Supplementary data upon submission. The Supplementary data should be referred to in the main manuscript, for example by citing consecutively supplemental tables and figures.

Units of measure

Laboratory values should be expressed using SI units (e.g. mmol/L). Blood pressure should be given in millimeters of mercury and body temperature in degrees Celsius. If conventional units are used, relevant SI conversion factors should be given in parentheses only at first mention and in table footnotes (e.g. “Conversion factors to SI units are as follows: for glucose [in mg/dL] – 0.0551, …”).

EXPERIMENTAL ETHICS AND REPORTING

Studies should comply with the Declaration of Helsinki, and the research protocol must be approved by the locally appointed Ethics Committee. Informed consent must be obtained from the subjects (or their legally authorised representative). The data regarding this issue must be stated in the Methods section of the manuscript. In the case of animal experimentation, authors should also obtain ethical and/or legal approval prior to conducting the research.

Clinical trials

Randomised clinical trials should be reported according to the Consolidated Standards of Reporting Trials (CONSORT) guidelines. All clinical trials, in particular those involving pharmaceuticals, devices, or aspects relating to nutrition, should be registered prospectively in publicly accessible databases (such as www.clinicaltrials.gov and www.clinicaltrialsregister.eu), and the paper should include registration numbers and the name of the register.

Informed patient consent

Authors should observe high standards with respect to publication ethics as set out by the Committee on Publication Ethics (COPE) and International Committee of Medical Journal Editors (ICMJE) recommendations for reporting about patients. Patients have a right to privacy that should not be infringed without prior informed consent.

Identifying information should not be published in written descriptions, photographs, and pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) has given written informed consent for publication. Informed consent for this purpose requires the patient be presented in the manuscript.

Identifying details should be omitted if they are not essential, but patient data should never be altered or falsified to attain anonymity.

The editor-in-chief reserves the right to reject papers for which the ethical aspects may raise doubts. For any queries regarding consent, please contact the editorial office.

FUNDING

In order to meet funding requirements, authors are required to name their funding sources, or state if there are none, during the submission process.

Details of all funding sources for the work in question should be given in the 'Acknowledgements' section. The following rules should be followed:

  • The sentence should begin: ‘This work was supported by…’
  • The full official funding agency name should be given, i.e. ‘National Institutes of Health’ not ‘NIH'. Grant numbers should be complete and accurate and provided in brackets as follows: ‘[grant number ABX CDXXXXXX]’.
  • Multiple grant numbers should be separated by a comma as follows: ‘[grant numbers ABX CDXXXXXX, EFX GHXXXXXX]’.
  • Agencies should be separated by a semi-colon (plus ‘and’ before the last funding agency).
  • Where individuals need to be specified for certain sources of funding the following text should be added after the relevant agency or grant number ‘to [author initials]’.

USE OF COPYRIGHTED MATERIAL

If illustrations or tables used in the manuscript come from other papers or published sources, written permission must be obtained from the owner of copyright, usually a publisher or author, and a credit line giving the source should be added to the legend. In the case of short quotations, it is sufficient to add a bibliographic credit. Permission letters for reproduced text or illustrations must accompany the manuscript. The inability to obtain permission should be clearly stated.

PROOFS

PDF proofs will be e-mailed to the corresponding author. The accepted manuscript will be edited by in-house editors to ensure consistency with the journal formatting style and sufficient level of English. It is the responsibility of the corresponding author to check proofs carefully, in particular, to check typesetting, editing, and completeness and correctness of the text, tables, and figures. Major alterations (other than corrections of typesetting errors) instigated by the author at proof stage are not allowed. Proofs should be returned to the publisher within three working days of receipt. Proofs are also read by the editor-in-chief, who reserves the right of final decision. Requests to publish corrections of errors after the manuscript has been published should be sent to the editorial office at kardiologiapolska@ptkardio.pl.
