    Your Paper Your Way

    We now differentiate between the requirements for new and revised submissions. You may choose to submit your manuscript as a single Word or PDF file to be used in the refereeing process. Only when your paper is at the revision stage, will you be requested to put your paper in to a 'correct format' for acceptance and provide the items required for the publication of your article.
    To find out more, please visit the Preparation section below.

    Information for Authors

    All articles except letters to the editor and supplements must be submitted online at http://ees.elsevier.com/ahj. The American Heart Journal no longer accepts submissions by mail. Letters to the editor must be submitted directly to Rebecca L. Hines, Managing Editor, at AHJ@dm.duke.edu. Supplement proposals must be submitted to Craig Smith at C.Smith@Elsevier.com. The Journal will consider for publication suitable articles on topics pertaining to the broad discipline of cardiovascular disease. Our goal is to provide the reader with primary investigation, scholarly review, and opinion concerning the practice of cardiovascular medicine. We especially encourage submission of 3 types of reports that are not frequently seen in cardiovascular journals: negative clinical studies, reports on study designs, and studies involving the organization of medical care. (For more information, see "What We Publish in the American Heart Journal and Why," by Daniel B. Mark, MD, MPH, [Am Heart J 2007;154:1-2].) The Journal does not accept individual case reports or original articles involving bench laboratory or animal research. All communications relating to the editorial management of the Journal should be sent to Rebecca L. Hines, Managing Editor, at AHJ@dm.duke.edu.

    Editorial policies. Statements and opinions expressed in the Journal are those of the author(s) and not necessarily those of the Editor(s) or publisher, and the Editor(s) and publisher disclaim any responsibility or liability for such material. Neither the Editor(s) nor the publisher guarantees, warrants, or endorses any product or service advertised in this publication; neither do they guarantee any claim made by the manufacturer of such product or service. In accordance with the Copyright Act of 1976, which became effective January 1, 1978, the following statement signed by all authors must accompany each manuscript accepted for publication: "The undersigned author(s) transfer all copyright ownership of the manuscript [title of article] to Elsevier Inc., in the event the work is published. The undersigned warrant(s) that the article is original, does not infringe upon any copyright or other proprietary right of any third party, is not under consideration by another journal, and has not been published previously." When a manuscript is accepted for publication, the Copyright Release Form will be issued to authors from the publisher.

    Review. All articles are pre-screened by the Editors and Associate Editors. Papers felt not to be competitive for publication or papers not consistent with the editorial priorities of the American Heart Journal will be returned to the authors without review within 4 weeks of submission. All other articles are reviewed by external referees. Acceptance is based on significance, originality, and validity of the material. If the article is accepted for publication, editorial revisions may be made to aid clarity and understanding without altering the meaning.

    Sections. The following sections are established features of the Journal. To ensure that the manuscript is considered for one of the following sections, the name of the intended section should appear at the top of the title page.

    Clinical Investigations. Original, in-depth clinical investigations. Word limit is 5000 and includes title page, abstract, tables, figures, and references.

    Curriculum in Cardiology. Concise, comprehensive, contemporary articles presenting core, updated information necessary for the continuing medical education of the modern clinical cardiologist. Maximum number of references is 50; word limit is 7500 and includes title page, abstract, tables, figures, and references.

    Conflict of interest

    All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. If there are no conflicts of interest then please state this: 'Conflicts of interest: none'. See also http://www.elsevier.com/conflictsofinterest. Further information and an example of a Conflict of Interest form can be found at: http://help.elsevier.com/app/answers/detail/a_id/286/p/7923.

    Contributors

    Each author is required to declare his or her individual contribution to the article: all authors must have materially participated in the research and/or article preparation, so roles for all authors should be described. The statement that all authors have approved the final article should be true and included in the disclosure.

    Registration of randomized clinical trials. Any manuscript submitted to the Journal that concerns the design or results of a randomized clinical trial must include the registration site (such as www.clinicaltrials.gov) and the registration number in the Methods section.

    Funding body agreements and policies

    Elsevier has established agreements and developed policies to allow authors whose articles appear in journals published by Elsevier, to comply with potential manuscript archiving requirements as specified as conditions of their grant awards. To learn more about existing agreements and policies please visit http://www.elsevier.com/fundingbodies.

    Open access. This journal offers you the option of making your article freely available via the ScienceDirect platform. To prevent any conflict of interest, you can make this choice only after receiving notification that your article has been accepted for publication. The fee of $3,000 excludes taxes and other potential author fees such as color charges. In some cases, institutions and funding bodies have entered into agreement with Elsevier to meet these fees on behalf of their authors. Details of these agreements are available at http://www.elsevier.com/fundingbodies. Authors of accepted articles who wish to take advantage of this option should complete and submit the order form (available at http://www.elsevier.com/locate/openaccessform.pdf). Whatever access option you choose, you retain many rights as an author, including the right to post a revised personal version of your article on your own website. More information can be found here: http://www.elsevier.com/authorsrights.

    The open access publication fee for this journal is $3,000, excluding taxes. Learn more about Elsevier's pricing policy: http://www.elsevier.com/openaccesspricing.

    Human research. Authors should identify that informed consent was obtained when applicable. The manuscript should also include the notation that the study was approved by the institutional committee on human research. Photographs of identifiable persons must be accompanied by signed releases showing informed consent. These should be included at the time of manuscript submission.

    Submission

    Our online submission system guides you stepwise through the process of entering your article details and uploading your files. The system converts your article files to a single PDF file used in the peer-review process. Editable files (e.g., Word, LaTeX) are required to typeset your article for final publication. All correspondence, including notification of the Editor's decision and requests for revision, is sent by e-mail.

    Submit your article
    Please submit your article via http://ees.elsevier.com/ahj.

    Preparation of manuscripts. Only original manuscripts will be considered for publication. Correct preparation of the manuscript by the authors will expedite the review and publication procedures. Please note the following requirements. Following the instructions for online submission at http://ees.elsevier.com/ahj, the article, including all tables, should be formatted in Microsoft Word. The use of appropriate subheadings throughout the body of the text (Methods, Results, and Discussion sections) is required. Figures and illustrations must also be submitted electronically as separate files. File specifications are listed below in "Illustrations, figures, and legends."

    NEW SUBMISSIONS

    Submission to this journal proceeds totally online and you will be guided stepwise through the creation and uploading of your files. The system automatically converts your files to a single PDF file, which is used in the peer-review process.
    As part of the Your Paper Your Way service, you may choose to submit your manuscript as a single file to be used in the refereeing process. This can be a PDF file or a Word document, in any format or lay-out that can be used by referees to evaluate your manuscript. It should contain high enough quality figures for refereeing. If you prefer to do so, you may still provide all or some of the source files at the initial submission. Please note that individual figure files larger than 10 MB must be uploaded separately.

    References

    There are no strict requirements on reference formatting at submission. References can be in any style or format as long as the style is consistent. Where applicable, author(s) name(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter and the pagination must be present. Use of DOI is highly encouraged. The reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage. Note that missing data will be highlighted at proof stage for the author to correct.

    Formatting requirements

    There are no strict formatting requirements but all manuscripts must contain the essential elements needed to convey your manuscript, for example Abstract, Keywords, Introduction, Materials and Methods, Results, Conclusions, Artwork and Tables with Captions.
    If your article includes any Videos and/or other Supplementary material, this should be included in your initial submission for peer review purposes.
    Divide the article into clearly defined sections.

    Figures and tables embedded in text
    Please ensure the figures and the tables included in the single file are placed next to the relevant text in the manuscript, rather than at the bottom or the top of the file.

    REVISED SUBMISSIONS

    Use of word processing software
    Regardless of the file format of the original submission, at revision you must provide us with an editable file of the entire article. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier: http://www.elsevier.com/guidepublication). See also the section on Electronic artwork.
    To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.

    Style. Manuscripts must conform to acceptable English usage. Standard abbreviations should be used consistently throughout the article. Abbreviations should be spelled out the first time they appear in the text and followed in parentheses by the abbreviation. Consult the latest editions of Scientific Style and Format by the Council of Biology Editors, The Chicago Manual of Style by The University of Chicago Press, or the AMA's Manual of Style, 9th edition, for current usage.

    Pagination. Begin numbering with the title page as page 1, the structured abstract page as page 2, and continue throughout the references, figure legends, and tables. Place page numbers on each page.

    Title page. The title page should be typed double-spaced and should include the title, authors' full names, highest earned academic degrees, institutional affiliations and location, and a short, abbreviated title of 40 characters or fewer. Designate one author (provide address, business telephone and fax numbers, and e-mail address) to receive correspondence, galley proofs, and reprint requests. This journal publishes author-accepted manuscripts online; therefore, do not include in the manuscript any information such as home telephone number that you do not wish to be made publicly available.

    Structured abstract. Each article must include a structured abstract of no more than 250 words. Use the following headings for sections of the abstract: Background, Methods, Results, Conclusions. The abstract may not contain data not presented in the manuscript. For review articles and trial designs, in place of a structured abstract, please provide a summary abstract paragraph (maximum word count 250 words). If abstract subheadings are not appropriate, they may be omitted.

    Graphical abstract

    Although a graphical abstract is optional, its use is encouraged as it draws more attention to the online article. The graphical abstract should summarize the contents of the article in a concise, pictorial form designed to capture the attention of a wide readership. Graphical abstracts should be submitted as a separate file in the online submission system. Image size: Please provide an image with a minimum of 531 × 1328 pixels (h × w) or proportionally more. The image should be readable at a size of 5 × 13 cm using a regular screen resolution of 96 dpi. Preferred file types: TIFF, EPS, PDF or MS Office files. See http://www.elsevier.com/graphicalabstracts for examples.
    Authors can make use of Elsevier's Illustration and Enhancement service to ensure the best presentation of their images and in accordance with all technical requirements: Illustration Service.

    Highlights

    Highlights are mandatory for this journal. They consist of a short collection of bullet points that convey the core findings of the article and should be submitted in a separate editable file in the online submission system. Please use 'Highlights' in the file name and include 3 to 5 bullet points (maximum 85 characters, including spaces, per bullet point). See http://www.elsevier.com/highlights for examples.

    Acknowledgements

    Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).

    Footnotes

    Footnotes should be used sparingly. Number them consecutively throughout the article. Many wordprocessors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.

    Artwork

    Electronic artwork
    General points
    • Make sure you use uniform lettering and sizing of your original artwork.
    • Preferred fonts: Arial (or Helvetica), Times New Roman (or Times), Symbol, Courier.
    • Number the illustrations according to their sequence in the text.
    • Use a logical naming convention for your artwork files.
    • Indicate per figure if it is a single, 1.5 or 2-column fitting image.
    • For Word submissions only, you may still provide figures and their captions, and tables within a single file at the revision stage.
    • Please note that individual figure files larger than 10 MB must be provided in separate source files.
    A detailed guide on electronic artwork is available on our website:
    http://www.elsevier.com/artworkinstructions.
    You are urged to visit this site; some excerpts from the detailed information are given here.
    Formats
    Regardless of the application used, when your electronic artwork is finalized, please 'save as' or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
    EPS (or PDF): Vector drawings. Embed the font or save the text as 'graphics'.
    TIFF (or JPG): Color or grayscale photographs (halftones): always use a minimum of 300 dpi.
    TIFF (or JPG): Bitmapped line drawings: use a minimum of 1000 dpi.
    TIFF (or JPG): Combinations bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is required.
    Please do not:
    • Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); the resolution is too low.
    • Supply files that are too low in resolution.
    • Submit graphics that are disproportionately large for the content.

    Color artwork
    Please make sure that artwork files are in an acceptable format (TIFF (or JPEG), EPS (or PDF), or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color on the Web (e.g., ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in color in the printed version. For color reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article. Please indicate your preference for color: in print or on the Web only. For further information on the preparation of electronic artwork, please see http://www.elsevier.com/artworkinstructions.
    Please note: Because of technical complications that can arise by converting color figures to 'gray scale' (for the printed version should you not opt for color in print) please submit in addition usable black and white versions of all the color illustrations.

    If a figure has been taken from previously copyrighted material, the legend must give full credit to the original source and letters of permission must be submitted with the manuscript. Articles appear in both the print and online versions of the Journal, and wording of the letter should specify permission in both forms of media. Failure to get electronic permission rights may result in the images not appearing in the online version.

    Figure captions
    Ensure that each illustration has a caption. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

    Tables. Tables should be self-explanatory and numbered in Roman numerals in the order of their mention in the text. Provide a brief title for each. Type each double-spaced on a separate page. Abbreviations should be defined in a double-spaced footnote at the end of the table. If any material in a table or a table itself has been taken from previously copyrighted material, a double-spaced footnote must give full credit to the original source and permission of the copyright holder must be obtained. Include letters of permission at the time of manuscript submission.

    Footnotes that require symbols must use those that are appropriate for the Journal. The accepted symbols, in the order in which they should appear within the table and within the footnotes, are: *, †, ‡, §, ||, ¶, #, **, ††, etc.

    Reference formatting
    There are no strict requirements on reference formatting at submission. References can be in any style or format as long as the style is consistent. Where applicable, author(s) name(s), journal title/book title, chapter title/article title, year of publication, volume number/book chapter and the pagination must be present. Use of DOI is highly encouraged. The reference style used by the journal will be applied to the accepted article by Elsevier at the proof stage. Note that missing data will be highlighted at proof stage for the author to correct. If you do wish to format the references yourself they should be arranged according to the following examples:

    Reference style
    References. The reference list must be numbered serially in the order in which the references appear in the text and typed double-spaced on separate sheets. Reference format should conform to the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" (Ann Intern Med 1997;126:36-47 or http://www.icmje.org ). Reference citations to periodicals should include, in the following order: names of the first 3 authors (and et al as necessary to signify any additional authors), title, journal, year, volume, and pages; for example, Hope RR, Scherlag BJ, Lazzara R. Excitation of ischemic myocardium: altered properties of conduction, refractoriness, and excitability. Am Heart J 1980;99:753-65. Journal abbreviations must follow the style used in Cumulated Index Medicus. Book references should include, in the following order: names of the first 3 authors, chapter title, editor(s), book title, volume (if any), edition (if any), city, publisher, year, and inclusive pages of citation (if any); for example, Sherry S. Detection of thrombi. In: Strauss HE, Pitt B, James AE, editors. Cardiovascular nuclear medicine. St. Louis: Mosby; 1974. p. 273-85. Unpublished data and personal communications may be cited in the text but not as references. Authors are responsible for the accuracy of references.

    AudioSlides

    The journal encourages authors to create an AudioSlides presentation with their published article. AudioSlides are brief, webinar-style presentations that are shown next to the online article on ScienceDirect. This gives authors the opportunity to summarize their research in their own words and to help readers understand what the paper is about. More information and examples are available at http://www.elsevier.com/audioslides. Authors of this journal will automatically receive an invitation e-mail to create an AudioSlides presentation after acceptance of their paper.

    Submission checklist

    The following list will be useful during the final checking of an article prior to sending it to the journal for review. Please consult this Guide for Authors for further details of any item.
    Ensure that the following items are present:
    One author has been designated as the corresponding author with contact details:
    • E-mail address
    • Full postal address
    • Telephone
    All necessary files have been uploaded, and contain:
    • Keywords
    • All figure captions
    • All tables (including title, description, footnotes)
    Further considerations
    • Manuscript has been 'spell-checked' and 'grammar-checked'
    • All references mentioned in the Reference list are cited in the text, and vice versa
    • Permission has been obtained for use of copyrighted material from other sources (including the Web)
    • Color figures are clearly marked as being intended for color reproduction on the Web (free of charge) and in print, or to be reproduced in color on the Web (free of charge) and in black-and-white in print
    • If only color on the Web is required, black-and-white versions of the figures are also supplied for printing purposes
    For any further information please visit our customer support site at http://support.elsevier.com.

    Online proof correction

    Corresponding authors will receive an e-mail with a link to our online proofing system, allowing annotation and correction of proofs online. The environment is similar to MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors.
    If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF.
    We will do everything possible to get your article published quickly and accurately. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor.It is important to ensure that all corrections are sent back to us in one communication. Please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.

    Once an article is published online as an Article in Press, no further corrections can be made to the article, except as an erratum or corrigendum, and then only at the Editor's discretion to correct a scientific error.

    Reprints. Single reprints must be obtained from the author. Reprint order forms will be sent to authors along with their galley pages.
