    The Journal of the American College of Cardiology (JACC) publishes peer­reviewed articles on all aspects of cardiovascular disease, including original clinical studies, experimental investigations with clear clinical relevance, state-of-the-art papers,and viewpoints. In general, case reports will not be considered for publication.

    General guidelines for submission of Original Research Papers

    Because of the printed page limitations, the Editors require that manuscripts not exceed 4,500 words (including references and figure legends). Note that if you are asked to revise your paper an alternate word limit may be specified by the Editors. Illustrations and tables should be limited to those necessary to highlight key data. Please provide gender-specific data, when appropriate, in describing outcomes of epidemiologic analyses or clinical trials; or specifically state that no gender-based differences were present.

    For original research dealing with genetic associations authors should refer to the following article: Ginsburg GS, Shah SH, McCarthy JJ. Taking cardiovascular genetic association studies to the next level. J Am Coll Cardiol 2007;50:930–2.

    The manuscript should be arranged as follows: 1) title page; 2) structured abstract and key words; 3) abbreviations list; 4) text; 5) acknowledgments (if applicable); 6) references; 7) figure titles and legends; and 8) tables. Page numbering should begin with the title page.

    Other paper categories

    The following information should be noted for these paper types:

    State-of-the-Art Papers. The Editors will consider both invited and uninvited review articles. Such manuscripts must adhere to preferred length guidelines and require an unstructured abstract of no more than 250 words. Authors should detail in their cover letters how their submission differs from existing reviews on the subject.

    Expedited Publications. Manuscripts in this category should report important original findings of high-potential clinical impact or research significance. They can be either a full-length paper or a short report presenting early findings. Authors must apply for expedited publication consideration in their cover letter at the time of submission. The Editors commit to a decision regarding suitability for expedited publication processing within 5 days, and an initial decision within 14 days. Those manuscripts not deemed appropriate for the expedited publication track will be eligible for consideration according to the standard review process. Print publication of an expedited publication will be accomplished within 6 weeks of receiving the approved galley proofs. Online publication will occur within 10 days of receiving the approved galley prints.

    Editorials and Viewpoints. Succinct opinion pieces will also be considered. These papers should have a brief unstructured abstract.

    Editorial Comments. The editors invite all Editorial Comments published in the Journal.

    Letters to the Editor. A limited number of letters will be published. They should not exceed 500 words and should focus on a specific article that has appeared in JACC. Letters must be submitted within 3 weeks of the print issue date of the article. No original data may be included. Type letters double-spaced and include the cited article as a reference. Provide a title page that includes authors’ names and institutional affiliations and a complete address for correspondence. These can be submitted online at Replies will generally be solicited by the Editors.

    Research Correspondence. Research Correspondence papers are original research articles of a focused nature. These papers are limited to a total of 1,000 words including references (no more than 5), and to one figure or table. These papers do not need an abstract.

    Images in Cardiology. The editors will consider original, high quality images showing novel or “classic” findings for publication, subject to editing and revision. The image(s) should not contain any material published elsewhere. Motion studies (i.e., videos) are encouraged. All videos must be linked to figures or panels of a figure(s). Submissions should be accompanied by a cover letter as well as a concise description of no more than 150 words including text and references. Please see the Video Requirements section elsewhere in the Instructions for Authors for details on video specifications. At the discretion of the Editors, images may appear in either the print or electronic version of JACC or both.

    Contact details for submission
    Please do not send hard copy manuscript submissions. If the manuscript absolutely cannot be submitted online, mail a disk containing all files to: Anthony N. DeMaria, MD, MACC, Editor-in- Chief, Journal of the American College of Cardiology, 3655 Nobel Drive, Suite 630, San Diego, CA 92122. Tel: [+1] [858] 558-3411; Fax: [+1] [858] 558-3148. This disk must include files for the cover letter, manuscript, tables, and figures. If supplementary materials such as ‘‘in press’’ references are included, these files must also be on the disk.


    Studies should be in compliance with human studies committees and animal welfare regulations of the authors’ institutions and Food and Drug Administration guidelines.

    Human and animal rights

    Human studies must be performed with the subjects’ written informed consent. Authors must provide the details of this procedure and indicate that the institutional committee on human research has approved the study protocol. If radiation is used in a research procedure, the radiation exposure must be specified in the Methods.

    Studies on patients or volunteers require ethics committee approval and informed consent, which should be documented in your paper. Patients have a right to privacy. Therefore, identifying information, including patients’ images, names, initials, or hospital numbers, should not be included in videos, recordings, written descriptions, photographs,and pedigrees unless the information is essential for scientific purposes and you have obtained written informed consent for publication in print and electronic form from the patient (or parent, guardian or next of kin where applicable). If such consent is made subject to any conditions, theeditorial office must be made aware of all such conditions.

    Animal investigation must conform to the ‘‘Position of the American Heart Association on Research Animal Use,’’ adopted by the AHA on November 11, 1984. If equivalent guidelines are used, they should be indicated. The AHA position includes: 1) animal care and use by qualified individuals, supervised by veterinarians, and all facilities and transportation must comply with current legal requirements and guidelines; 2) research involving animals should be done only when alternative methods to yield needed information are not possible; 3) anesthesia must be used in all surgical interventions, all unnecessary suffering should be avoided and research must be terminated if unnecessary pain or fear results; and 4) animal facilities must meet the standards of the American Association for Accreditation of Laboratory Animal Care (AAALAC).

    Relationship With Industry Policy

    The Editors require authors to disclose any relationship with industry and financial associations from within the past 2 years that might pose a conflict of interest in connection with the submitted article in both the cover letter and on the title page. All sources of funding for the work should be acknowledged on the title page, as should all institutional affiliations of the authors (including corporate appointments). Other associations, such as consultancies, stock ownership, or other equity interests or patent-licensing arrangements, should be disclosed to the Editors in the cover letter at the time of submission. If no relationship with industry exists, please state this in the cover letter and on the title page. Relationship with industry guidelines apply to authors of all the following: Original Research Papers, State-of-the-Art Papers, Expedited Reviews, Editorials and Viewpoints, Research Correspondence, and Editorial Comments.

    ALL FORMS ARE NOW SIGNED AND SUBMITTED ELECTRONICALLY. Once a manuscript is accepted, the authors will be sent links to complete electronic Copyright Transfer and Relationship with Industry forms. Only the corresponding author may electronically sign the copyright form; however, ALL AUTHORS ARE REQUIRED TO ELECTRONICALLY SIGN A RELATIONSHIP WITH INDUSTRY FORM. Once completed, a PDF version of the form is e-mailed to the author. Authors can access and confirm receipt of forms by logging into their account online. Each author will be alerted if his form has not been completed by the deadline.

    Only authors appearing on the final title page will be sent a form. YOU CANNOT ADD AUTHORS AFTER ACCEPTANCE OR ON PROOFS. After a paper is sent to the publisher, the links to the electronic forms will no longer be active. In this case, authors will be sent links to download hard copy forms that they may mail or fax to the JACC office.

    Exclusive submission/publication policy

    The manuscripts are considered for review only under the conditions that they are not under consideration elsewhere and that the data presented have not appeared on the internet or have not been previously published (including symposia, proceedings, transactions, books, articles published by invitation, and preliminary publications of any kind except abstracts not exceeding 400 words). On acceptance, transfer of copyright to the American College of Cardiology Foundation will be required. Elsevier Inc. will maintain copyright records for the College.

    Author contribution

    Each author must have contributed significantly to the submitted work. If there are more than 4 authors, the contribution of each must be substantiated in the cover letter. If authorship is attributed to a group (either solely or in addition to1or more individual authors), all members of the group must meet the full criteria and requirements for authorship. To save space, if group members have been listed in JACC, the article should be referenced rather than reprinting the list.


    The Editors consider authorship to include all of the following: 1) conception and design or analysis and interpretation of data, or both; 2) drafting of the manuscript or revising it critically for important intellectual content; and 3) final approval of the manuscript submitted. Participation solely in the collection of data does not justify authorship but may be appropriately acknowledged in the Acknowledgment section.

    Open access

    This journal does not ordinarily have publication charges; however, authors can now opt to make their articles available to all (including non-subscribers) via the ScienceDirect platform, for which a fee of US $3000 applies (for further information on open access see Please note that you can only make this choice after receiving notification that your article has been accepted for publication, to avoid any perception of conflict of interest. The fee excludes taxes and other potential costs 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 Authors of accepted articles, who wish to take advantage of this option, should complete and submit the order form (available at 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:
    Your publication choice will have no effect on the peer review process or acceptance of submitted articles.

    Language services
    English language help service: Upon request, Elsevier will direct authors to an agent who can check and improve the English of their paper (before submission). Please contact for further information.

    Informed consent and patient details

    Written consents must be provided to the editorial office on request. Even where consent has been given, identifying details should be omitted if they are not essential. If identifying characteristics are altered to protect anonymity, such as in genetic pedigrees, authors should provide assurance that alterations do not distort scientific meaning and editors should so note. If such consent has not been obtained, personal details of patients included in any part of the paper and in any supplementary materials (including all illustrations and videos) must be removed before submission.


    We request that all manuscripts be submitted online at

    Manuscript submissions should conform to the guidelines set forth in the ‘‘Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication,’’ available from and most recently updated in April 2010.


    The text should be structured as Introduction, Methods, Results, and Discussion. Use headings and subheadings in the Methods, Results, and, particularly, Discussion sections. Every reference, figure and table should be cited in the text in numerical order according to order ofmention.

    Cover letter

    Manuscripts must be submitted with a cover letter stating that: 1) the paper is not under consideration elsewhere; 2) none of the paper’s contents have been previously published; 3) all authors have read and approved the manuscript; and 4) the full disclosure of any relationship with industry (see “Relationship with Industry Policy”). Exceptions must be explained.

    The corresponding author should be specified in the cover letter. All editorial communications will be sent to this author. The corresponding author will be whom we contact for submission queries. A short paragraph telling the editors why the authors think their paper merits publication priority may be included in the cover letter. Potential reviewers may be suggested in the cover letter, as well as reviewers to avoid.

    Title page

    Include the title, authors’ names (including full first name and middle initial and degrees), total word count, and a brief title of no more than 45 characters. List the departments and institutions with which the authors are affiliated, and indicate the specific affiliations if the work is generated from more than one institution (use the footnote symbols given under “Tables”). Also provide information on grants, contracts, and other forms of financial support, and list the cities and states of all foundations, funds and institutions involved in the work. Include any relationship with industry (see “Relationship with Industry Policy”). If there are no relationships with industry, this should be stated. Under the heading, “Address for correspondence,” give the full name and complete postal address of the author to whom communications, printer’s proofs, and reprint requests should be sent. Also provide telephone and fax numbers and an e-mail address.

    Structured abstract

    Provide a structured abstract of no more than 250 words, presenting essential data in 5 paragraphs introduced by separate headings in the following order: Objectives, Background,Methods, Results, and Conclusions. Use complete sentences. All data in the abstract must also appear in the manuscript text or tables. For general information on preparing structured abstracts, see ‘‘Haynes RB, Mulrow CD, Huth EJ, Altman DG, Gardner MJ. More informative abstracts revisited. Ann Intern Med 1990;113: 69–76.’’ A nonstructured abstract is appropriate for review articles.


    Immediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.


    To save space in the Journal, up to 10 abbreviations of common terms (e.g., ECG, PTCA, CABG) or acronyms (GUSTO, SOLVD, TIMI) may be used throughout the manuscript. On a separate page following the abstract, list the selected abbreviations and their definitions (e.g., TEE = transesophageal echocardiography). The Editors will determine which lesser known terms should not be abbreviated. Consult ‘‘Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication,’’ available from and most recently updated in April 2010, for appropriate use of units of measure.


    Acknowledgments or appendices must contain 100 words or less. Anything exceeding this limit will appear in the online version only. Letters of permission from all individuals listed in the acknowledgments are the responsibility of the corresponding author.


    All publishable manuscripts will be reviewed for appropriateness and accuracy of statistical methods and statistical interpretation of results. We subscribe to the statistics section of the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication,” available from and most recently updated in April 2010. In the Methods section, provide a subsection detailing the statistical methods, including specific methods used to summarize the data, methods used for hypothesis testing (if any), and the level of significance used for hypothesis testing. When using more sophisticated statistical methods (beyond t tests, chi-square, simple linear regression), specify the statistical package, version number, and nondefault options used. For more information on statistical review, see ‘‘Glantz SA. It is all in the numbers. J AmColl Cardiol 1993;21:835–7.’’


    Figures and graphs submitted in electronic format should be provided in EPS or TIF format. Graphics software such as Photoshop and Illustrator, NOT presentation software such as Power point, CorelDraw, or Harvard Graphics, should be used to create the art. Color images must be at least 300 DPI. Gray scale images should be at least 300 DPI. Line art (black and white or color) and combinations of gray scale images and line art should be at least 1200 DPI. Lettering should be of sufficient size to be legible after reduction for publication. The optimal size is 12 points. Symbols should be of a similar size. Figures should be no smaller than 13 cm x 18 cm (500 x 700). Please do not reduce figures to fit publication layout. If the manuscript is accepted for publication, the publisher will re-size the figures accordingly.

    Decimals, lines, and other details must be strong enough for reproduction. Use only black and white—not gray—in charts and graphs. Place crop marks on photomicrographs to show only the essential field. Designate special features with arrows. All symbols, arrows, and lettering on half-tone illustrations must contrast with the background.

    Non-electronic artwork
    Upon provisional acceptance, we may request 2 sets of glossy or laser prints (clean copies will suffice). Two sets of glossy prints should be provided for all half-tone or color illustrations. All graphs and line drawings must be professionally prepared on a computer and reproduced as high quality laser prints. Indicate the first author’s last name (and the corresponding author’s last name within parentheses, if different) and the figure number on the back of each figure, preferably on an adhesive label. Figure title and caption material must appear in the legend, not on the figure.

    Note: if we request hardcopies, they will not be returned to authors.

    Color artwork
    THERE IS NO FEE FOR THE PUBLICATION OF COLOR FIGURES. Our editors encourage authors to submit figures in color, as we feel it improves the clarity and visual impact of the images. If your original submission contains any line art or black and white figures that you would like to change to color, please mail two sets of high quality, glossy prints of all color figures to the JACC editorial office during the revision process. Be sure to include correspondence, with the manuscript number, explaining the change.

    Figure captions
    Figure legends should be typed double-spaced on pages separate from the text; figure numbers must correspond with the order in which they are mentioned in the text.

    ALL FIGURES MUST HAVE A TITLE AND CAPTION. The title should be short and followed by a 2 to 3 sentence caption. For example, Figure 1: Title - Caption, etc.

    All abbreviations used in the figure should be identified either after their first mention in the legend or in alphabetical order at the end of each legend. All symbols used (arrows, circles, etc.) must be explained.

    If previously published figures are used, written permission from the original publisher is required. See STM Guidelines for details: Cite the source of the figure in the legend.


    Tables should be typed double-spaced on separate sheets, with the table number and title centered above the table and explanatory notes below the table. Use arabic numbers. Table numbers must correspond with the order cited in the text.


    Abbreviations should be listed in a footnote under the table in alphabetical order. Footnote symbols should appear in the following order:

    *, †, ‡, x, §, ll, #, **, ††, etc.

    Tables should be self-explanatory, and the data presented in them should not be duplicated in the text or figures. If previously published tables are used, written permission from the original publisher and author is required. Cite the source of the table in the footnote.


    Do not cite personal communications, manuscripts in preparation, or other unpublished data in the references; these may be cited in the text in parentheses. Do not cite abstracts that are older than 2 years. Identify abstracts by the abbreviation ‘‘abstr’’ in parentheses. If letters to the editor are cited, identify them with the word ‘‘letter’’ in parentheses.

    Citations in text
    Identify references in the text by arabic numerals in parentheses on the line. The reference list should be typed double-spaced on pages separate from the text; references must be numbered consecutively in the order in which they are mentioned in the text.

    Reference style

    List all authors if 6 or fewer, otherwise list the first 3 and add et al.; do not use periods after the authors’ initials. Please do provide inclusive page numbers as in example below.

    Video requirements

    Inclusion of videos in the published paper is at the discretion of the Editors.

    1. Video submissions for viewing online should be one of the following formats: Audio Video Interleave (.avi), MPEG (.mpg), or Quick Time (.qt, .mov).

    AVI files can be displayed via Windows Media Player

    MPEG files can be displayed via Windows Media Player

    Quick Time files require Quick Time software (free) from Apple

    2. Videos should be brief whenever possible (<2–5 min). Longer videos will require longer download times and may have difficulty playing online. Videos should be restricted to the most critical aspects of your research. A longer procedure can be restructured as several shorter videos and submitted in that form.

    3. It is advisable to compress files to use as little bandwidth as possible and to avoid overly long download times. Video files should be no larger than 5 megabytes. This is a suggested maximum. If files are larger please contact the JACC office.

    4. A video legends page giving a brief description of the video content should be provided for each video.

    5. If your paper is accepted for publication you may wish to supply the editorial office with several different resolutions of your video files. This will allow viewers with slower connections to download a lower resolution version of your video.
