The Journal of the American College of Cardiology (JACC) publishes peer-reviewed articles highlighting 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 REVIEW ARTICLES
Although the review articles are invited manuscripts, we will happily consider high-caliber proposals. Please submit a pre-submission inquiry before your manuscript. After the manuscript is accepted for publication, the JACC editors will support the development of the review articles, and the professional JACC illustrators will redraw illustrations. The review articles are considered for publication in the following two formats.
1) Present and Future—State-of-the-Art Review: As with all submissions to JACC, State-of-the-Art Reviews should focus on the patient. From basic mechanisms to clinical manifestations and interventional approaches to global health implications, such manuscripts will focus on a contemporary, controversial, or translational topic with 4-5 major sections written by 4-5 authors (or 4-5 author groups). This should be submitted as 1 single, unified paper, and not as 4-5 individual manuscripts. The authors should strictly adhere to the text length guidelines (a 10,000-word maximum limit for the entire manuscript, with an unstructured abstract of no more than 150 words and no more than 5 tables). The manuscripts also can be formatted as point-counterpoint debates. We ask authors to provide a Central Illustration that summarizes the main concept of the review in a graphical or schematic manner. If the manuscript is accepted, the final figure would be drawn by an in-house medical illustrator. (See further explanation below.)2) Present and Future— Review Topic of the Week: As with all submissions to JACC, Review Topics of the Week should focus on the patient. These articles review a contemporary topic of basic, translational, or clinical science. Please e-mail the proposal to the office before submitting your paper (email@example.com). Such manuscripts may be written by a single author or an author group, and requires an unstructured abstract of no more than 150 words. The overall text length should not exceed 5,000 words and no more than 5 tables. We ask you to provide a Central Illustration (line or pictorial) that summarizes the main concept of the review. If the manuscript is accepted, the final figure will be drawn by an in-house medical illustrator. (See further explanation below.)
GENERAL GUIDELINES FOR SUBMISSION OF ORIGINAL RESEARCH PAPERS
Because of printed page limitations, manuscripts should not exceed 5,000 words (including references and figure legends). If you are asked to revise your paper, the editors may specify an alternate word limit. 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 there were no gender-based differences.For original research dealing with genetic associations, authors should refer to J Am Coll Cardiol 2007;50:930–2.
Expedited Publications. Original 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 should request expedited publication in their cover letter at the time of submission. The editors commit to a decision regarding suitability for expedited publication processing within 2 days, and an initial decision within 14 days. Those manuscripts not deemed appropriate for the expedited publication track will be considered according to the standard review process. We always inform authors whether we are able to offer expedited review.
Studies should be in compliance with human studies committees and animal welfare regulations of the authors’ institutions and the U.S. Food and Drug Administration guidelines.
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.
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).The JACC journals have an ethics committee comprised of 7 members, which oversee quality control and will look into the issues of concern, if any.
RELATIONSHIP WITH INDUSTRY POLICY
Authors are required to disclose any relationship with industry and other relevant entities—financial or otherwise—within the past 2 years that might pose a conflict of interest in connection with the submitted article 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). This includes associations such as consultancies, stock ownership, or other equity interests or patent-licensing arrangements. If no relationship with industry exists, please state this on the title page. Relationship with industry guidelines apply to all authors.
The JACC Journals program prefers the term Relationships with Industry and Other Entities as opposed to the term Conflict of Interest, because, by definition, it does NOT necessarily imply a conflict. When all relationships are disclosed with the appropriate detail regarding category and amount, and managed appropriately for building consensus and voting, the JACC Journals program believes that potential bias can be avoided and the final published document is strengthened since the necessary expertise is accessible.PERMISSIONS
No part of materials published in JACC may be reproduced without written permission of the publisher. Some materials qualify for gratis usage.

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, excepting abstracts that do not exceed 400 words). On acceptance, transfer of copyright to the American College of Cardiology Foundation will be required. Elsevier will maintain copyright records for the College.
Each author must have contributed significantly to the submitted work. If authorship is attributed to a group (either solely or in addition to 1 or 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.
Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND
Drafting the work or revising it critically for important intellectual content; AND
Final approval of the version to be published; AND
Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved. Participation solely in the collection of data does not justify authorship but may be appropriately acknowledged in the Acknowledgment section.
Authors must agree to the following ICMJE statements. These questions will be part of the submission process and manuscripts will not be reviewed until they are confirmed. 1) The paper is not under consideration elsewhere; 2) none of the paper's contents with the exception of abstracts have been previously published; 3) all authors have read and approved the manuscript; 4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved; 5) the full disclosure of any relationship with industry (see “Relationship with Industry Policy”) or that no such relationship exists, is stated; and 6) the authors have provided both an illustration and the appropriate material for inclusion in the box that appears after the “Conclusions” section in the manuscript. Exceptions must be explained.The corresponding author should be specified on the title page. 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.In order to add or remove any authors after acceptance of their paper, all listed authors at the time of acceptance need to provide written approval to the JACC Journals' editorial office prior to the scheduling and publication of the paper.
While this journal does not ordinarily have publication charges, authors can now opt to make their articles available to all (including non-subscribers) via the ScienceDirect platform, which carries a fee of US $3,000. (For further information on open access, visit http://www.elsevier.com/about/open-access/open-access-options.) To avoid any perception of conflict of interest, you can only make this choice after receiving notification that your article has been accepted for publication. 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 https://www.elsevier.com/fundingbodies. Authors of accepted articles who wish to take advantage of this option should complete and submit the order form, which is available at https://www.elsevier.com/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.

Green open access
Authors can share their research in a variety of different ways and Elsevier has a number of green open access options available. We recommend authors see our green open access page for further information. Authors can also self-archive their manuscripts immediately and enable public access from their institution's repository after an embargo period. This is the version that has been accepted for publication and which typically includes author-incorporated changes suggested during submission, peer review and in editor-author communications. Embargo period: For subscription articles, an appropriate amount of time is needed for journals to deliver value to subscribing customers before an article becomes freely available to the public. This is the embargo period and it begins from the date the article is formally published online in its final and fully citable form. Find out more.
This journal has an embargo period of 12 months.
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 firstname.lastname@example.org 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 http://www.jaccsubmit.org. If a manuscript absolutely cannot be submitted online, please contact the editorial office at email@example.com.
Manuscript submissions should conform to the guidelines set forth in the ‘‘Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations),’’ available from http://www.ICMJE.org and most recently updated in December 2014.TEXT
The text should be structured as Introduction, Methods, Results, Discussion, and Conclusions. Use headings and subheadings in the Methods, Results, and particularly in the Discussion sections. Every reference, figure, and table should be cited in the text in numerical order according to order of mention.
The authors should delineate clinical competencies and translational outlook recommendations for their manuscripts. These competencies should not restate the questions underlying the work but describe the implications of the study and how the new information can be integrated into current practice based on the 6 domains delineated by the Accreditation Council on Graduate Medical Education and adopted by the American College of Cardiology Foundation. These should be listed in the manuscript after the Text and before the References. Please review the examples provided below. The competencies describe the implications of the study for current practice. The translational outlook places the work in a futuristic context, emphasizing directions for additional research.
Translational Outlook. Translating biomedical research from the laboratory bench, clinical trials, or global observations to the care of individual patients can expedite discovery of new diagnostic tools and treatments through multidisciplinary collaboration. Effective translational medicine facilitates implementation of evolving strategies for prevention and treatment of disease in the community. The Institute of Medicine identified two areas needing improvement: testing basic research findings in properly designed clinical trials and, once the safety and efficacy of an intervention has been confirmed, more efficiently promulgating its adoption into standard practice (Sung NS, Crowley WF, Genel M. The meaning of translational research and why it matters. JAMA 2008;299:3140-8). The National Institutes of Health (NIH) has recognized the importance of translational biomedical research, emphasizing multifunctional collaborations between researchers and clinicians to leverage new technology and accelerate the delivery of new therapies to patients (www.ncats.nih.gov/about/about.html). Authors are asked to place their work in the context of the scientific continuum, by identifying impediments and challenges requiring further investigation and anticipating next steps and directions for future research.EXAMPLE 1: For a Clinical Trial [N Engl J Med 2012;367:2375-84]:
PERSPECTIVESCompetency in Medical Knowledge: Coronary artery bypass (CABG) surgery is the preferred method of revascularization for patients with diabetes and multivessel coronary artery disease.
Competency in Patient Care: The diabetic patient with coronary symptomatology, prior to the diagnostic catheterization, should be made aware that if multivessel disease is identified and intervention is indicated, surgical consultation should be entertained.
Translational Outlook 1: Although this is a relatively short-term study (median of 3.8 years), longer term follow up of FREEDOM will lead to better understanding of the comparative benefit by CABG, specifically on mortality.
EXAMPLE 2: For a Translational Science Study [Nat Med 2014;20:215-9]:PERSPECTIVES
Competency in Medical Knowledge: Inflammation is one of the major determinants of atherosclerotic plaque instability. Positron emission tomography with F18-labeled fluorodeoxyglucose (FDG) has been employed for the identification of the macrophages in high-risk patients. Imaging with mannose, the isomer of glucose, may have an advantage because a subset of macrophages in high-risk plaques develop mannose receptors.Translational Outlook 1: Although circulating biomarkers of inflammation, such as hs-CRP, provide reliable information of systemic inflammation, detection of inflammation at the plaque level may allow identification of the high-risk plaques.
Translational Outlook 2: Plaque imaging with sugars, although feasible, must in a randomized fashion investigate whether treatment of individual high-risk plaques would favorably influence major adverse outcomes in atherosclerotic disease.EXAMPLE 3: For a Meta-Analysis or a Review Article [Lancet 2014;383:955–62]:
PERSPECTIVESCompetency in Medical Knowledge 1: Selection of antithrombotic therapy for prevention of thromboembolism in patients with atrial fibrillation must consider several clinical factors, including the patient’s values and preferences.
Competency in Medical Knowledge 2: The oral direct thrombin inhibitor, dabigatran, and factor Xa inhibitors, rivaroxaban, apixaban, and edoxaban (so-called novel oral anticoagulants or NOACs) avoid the dietary restrictions and need for routine coagulation monitoring that are cumbersome aspects of anticoagulation with vitamin K antagonists such as warfarin.Competency in Patient Care: All 3 NOACs currently approved for clinical use in the United States represent advances over warfarin because of their more predictable pharmacological profiles, fewer drug interactions, and considerably lower risk of intracranial bleeding than warfarin, but these advantages come at greater monetary cost, and there is presently no approved antidote or validated strategy rapid reversal of anticoagulation induced by any of the NOACs.
Competency in Interpersonal & Communication Skills: It is important to discuss the available options with patients who are candidates for the newer agents.Translational Outlook 1: The mechanism by which each of the NOACs evaluated to date cause less intracerebral hemorrhage than well-managed warfarin anticoagulation requires further investigation.
Translational Outlook 2: Additional research is needed to understand the safety and efficacy of the NOACs, alone or in combination in patients with mechanical prosthetic heart valves to overcome the toxicity of this type of anticoagulation in the limited studies undertaken to date that contraindicate their use in patients who have undergone heart valve replacement with mechanical prostheses.OTHER PAPER CATEGORIES
The following information should be noted for these paper types:
Editorial Comments. The editors invite all Editorial Comments published in the Journal.Letters to the Editor. A limited number of letters will be published. The letters are of 2 types, however both types will be published under the heading Letters. Letters to the editor should have no more than 400 words, including references (no more than 5), and focus on a specific article that has appeared in JACC. Letters must be submitted within 3 months of the print issue date of the article. Please include the cited article as a reference.We may seek a reply to your letter from the authors of the original paper and publish together. Letters on Editorial Comments or previously published correspondence will not be considered.
Research Letters. You also may submit original research articles of a focused nature as a research letter. These focused articles are limited to a total of 800 words including references (no more than 5), no more than 10 authors, and to 1 figure or table, with no supplemental material or abstract.Fellows-in-Training/Early Career. These articles are a maximum of 1,500 words and focus on topics that are of unique relevance to these FITs and younger cardiologists. However, they must be substantive, really engaging in hard-hitting topics that impact their daily practice. In terms of style, they must be formal in their presentation, as these are not blogs, and include citations (if relevant). Also, we would encourage specificity when choosing a topic on which to write, as opposed to something that is too broad to have true impact. All authors must be within 10 years of medical school. Please note that these articles will be reviewed and may be rejected by the JACC Editors. These should NOT be submitted online but e-mailed to firstname.lastname@example.org. WORD COUNT
The word count includes the text from the introduction to the conclusion, plus figure legends and references. It does not include the title page, abstract, or tables.
Include the title, authors’ names (including full first name, 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 superscript letters a, b, c, d, and so on). Please list authors’ current email addresses as well. Also provide information on grants, contracts, and other forms of financial support. List the cities and states of all foundations, funds, and institutions involved in the work. This must include the full disclosure of any relationship with industry. (See the “Relationship with Industry Policy.”) If there are no relationships with industry, this should be stated. Under the heading, “Address for correspondence,” provide 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, fax numbers, and an e-mail address.
Provide a structured abstract of no more than 250 words, presenting essential data in 5 paragraphs introduced by separate headings in the following order: Background, Objectives, Methods, Results, and Conclusions. Please notice the change in the sequence of headings compared to what we used to publish earlier; now Background precedes Objectives. 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.’’ An unstructured 150-word abstract should be provided for the review articles.KEY WORDS
Immediately after the perspectives, provide a maximum of 6 key words, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, ‘and’, ‘of’). Be sparing with abbreviations. These key words will be used for indexing purposes, and therefore should be different than the terms/words already used in the title of the paper.
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 ‘‘Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations),’’ available at http://www.ICMJE.org for appropriate use of units of measure.
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 “Recommendations for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals (ICMJE Recommendations),” available at http://www.ICMJE.org. 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 Am Coll Cardiol 1993;21:835–7.’’
All Original Research Papers, State-of-the-Art Reviews, and Review Topics of the Week should develop at least 1 Central Illustration drawing or figure (that may be a simple/rough hand-drawn figure), which summarizes the entire manuscript or at least a major section of the manuscript. Our in-house medical illustrators will create the final printable versions of these figures in consultation with the authors and the editors. The purpose of these illustrations is to provide a snapshot of your paper in a single visual, conceptual manner. This illustration must be accompanied by a legend.
Figures and graphs submitted in electronic format should be provided in EPS or TIF format. Graphics software, such as Photoshop and Illustrator, should be used to create the art, but not presentation software such as Powerpoint, CorelDraw, or Harvard Graphics. 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 (5" x 7"). 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.
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.
All figures must have a Number, Title, and Caption. The title should be short and followed by a 2–3 sentence caption. All abbreviations used in the figure should be identified in an alphabetical order at the end of each legend. All symbols used (arrows, circles, etc.) must be explained. 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.
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:*, †, ‡, §, 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.REFERENCES
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.
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.
