  5. Email one copy of any abstracts published or submitted for publication, if applicable (if not uploaded online).

2. MANUSCRIPT PREPARATION

Journal Categories. Note the length restrictions and other eligibility criteria listed below. Word limits include all sections of the manuscript text, figure legend(s), table(s), and references.

ORIGINAL CONTRIBUTIONS. The purpose of this category is to publish articles consisting of new material or original research.
Length Limit = 6,000 words. Display Item Limit = 8 Figures and/or Tables. Word limit includes table(s), figure legend(s), references.

REPORTS. The purpose of this category is to enable rapid review and publication of important scientific findings that can be explained and documented concisely. A first decision is reached within 21 days of submission, and publication in the print journal is within 4 weeks of acceptance. The length is strictly limited to three printed pages in the journal. Reports may use more or less words depending on the number and size of display items. Submissions that are overly long will either be returned for abbreviation or processed in another category, according to the authors' preference. The abstract should be terse and limited to an explanation of the question addressed and the central findings. Within the text, separation into sections (Introduction, Materials and Methods, Results, Discussion) is optional. Citations should follow journal style.
Length Limit = 2,200 words. Display Item Limit = 3 Figures and/or Tables. Word limit includes table(s), figure legend(s), references.

ULTRARAPID COMMUNICATIONS. The category of UltraRapid Communications uses the medium of Web publishing. A first decision on these manuscripts, which should be of unusually high priority, is made within 21 days of receipt at the editorial office. Once accepted, the full article is published ONLINE ONLY in the next available issue, with the abstract published in the print version. UltraRapid Communications undergo the same peer review and copyediting processes as Original Contributions, are assigned volume and page numbers for citation, and are listed in indexing services such as MEDLINE. Please note that no color reprints are available to authors for UltraRapid Communications, although online material can appear in color.
No Length Limit. No Display Item Limit.

RESEARCH COMMENTARIES. Research Commentaries provide a peer-reviewed forum for focused critiques on work that has been published in this journal. Research Commentaries contain new material or original research related to the prior published work but are sufficiently focused that consideration in other categories is not appropriate. Research Commentaries are published online with a condensed abstract appearing in the print journal. The authors of the article being critiqued are invited to respond. Both the Research Commentary and the response undergo peer review. Research Commentaries follow the same submission guidelines as Original Contributions. Please note that no color reprints are available to authors for Research Commentaries.
Length Limit = 6,000 words. Display Item Limit = 8 Figures and/or Tables. Word limit includes table(s), figure legend(s), references.

MINIREVIEWS. MiniReviews are intended to highlight timely topics in the biology of the cardiovascular system. The majority of MiniReviews are commissioned; however, noncommissioned articles may be considered at the editors' discretion. All MiniReviews, whether commissioned or not, undergo regular peer review. MiniReviews are intended to be succinct discussions dealing with a particular question of current interest. Figures are encouraged, but only of a diagrammatic nature.
Length Limit = 6,000 words. Display Item Limit = 3 Figures and/or Tables. Word limit includes table(s), figure legend(s), references.

REVIEWS. Longer and more comprehensive than MiniReviews, Reviews may be considered as definitive summaries of important areas. As with MiniReviews, most are commissioned; however, noncommissioned articles may be considered at the editors' discretion. All Reviews, whether commissioned or not, undergo regular peer review.
Length Limit = 12,000 words. Display Item Limit = 8 Figures and/or Tables. Word limit includes table(s), figure legend(s), references.

EDITORIALS. Generally these are brief commentaries on articles that appear in Circulation Research. Editorials are invited and are subject to review by the editors.
Length Limit = 2,000 words. Display Item Limit = 2 Figures and/or Tables. Word limit includes table(s), figure legend(s), references.

SPECIAL ARTICLES. The Editors may, at their discretion, choose to publish select manuscripts as Special Articles. Such articles are generally commissioned and may present a combination of personal opinion and factual data.

LETTERS TO THE EDITOR. Letters are opinion pieces on work published in Circulation Research and are reviewed by the Editors to establish scientific decorum, overall level of interest, and appropriateness as contributions to the scientific literature. Replies are not routinely solicited in advance from the authors of articles addressed, but are welcome if the authors believe a reply is warranted. Letters to the Editor (and replies, which are also published as Letters) will appear online only. Letters to the Editor may not exceed 1,000 words in length. Figures and tables are generally not permitted. Citations should follow journal style. Letters are distinguished from Research Commentaries by their length and content. Research Commentaries are substantive articles containing new data. Unlike Letters, Research Commentaries undergo peer review, and a reply is routinely solicited from the authors of the article that prompted the commentary.
Length Limit = 1,000 words. No Display Items Allowed. Word limit includes references.

General Manuscript Preparation Guidelines

  • Submitted manuscripts must not contain previously published material and must not be under consideration for publication elsewhere in whole or in part in any language (except as an abstract; See "Prior Publication" for the definition of an abstract). Manuscripts must conform to "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" (http://www.icmje.org).
  • Manuscripts must be double-spaced, including references and figure legends.
  • Manuscripts must be organized in this order: title page, abstract, introduction, materials and methods, results, discussion, acknowledgments, sources of funding, disclosures, references, figure legends, tables, figures.
  • Word limits noted for each manuscript category include all sections of the manuscript: Title Page, Abstract, Text, Acknowledgment and COI Sections, References, Figure Legends, and Tables. Online Data Supplements are excluded from the word limit.
  • Leave 1-inch margins on all sides. Number all pages--including figure legends, tables, and figures-- except the title page.
  • Cite each figure and table in text in numerical order. Cite each reference in text in numerical order and list in the References section. In text, reference numbers may be repeated but not omitted.
  • Use SI units of measure in all manuscripts. For example, molar (M) should be changed to mol/L; mg/dL to mmol/L; and cm to mm. Units of measure previously reported as percentages (ie, hematocrit) are expressed as a decimal fraction. Measurements currently not converted to SI units in biomedical applications are blood and oxygen pressures, enzyme activity, H+ concentration, temperature, and volume. The SI unit should be used in text, followed by the conventionally used measurement in parentheses.
  • Materials submitted, including figures, cannot be returned to authors regardless of the disposition of the article.

    • Title Page

  • Include the full title, short title of 50 characters or less, all author names, all author affiliations, and the full contact information for the corresponding author.
  • Include two to five subject codes that best classify your manuscript, using the Subject Code List for Authors.

    • Abstract

  • Abstract length is limited to 250 words.
  • Abbreviations must be defined at first mention in the abstract, and again at first mention in the main manuscript text.
  • Do not cite references in abstract, and limit use of acronyms and abbreviations. Do not use subheadings. The abstract must include the rationale for the study, a brief description of methods and presentation of significant results, and a succinct statement of data interpretation.
  • Provide 3 to 5 key words for use as indexing terms. These words may later be copyedited to conform to journal style.

    • Materials and Methods

  • Materials and Methods should be limited to essential new information. Information that is presented from previous publications should be cited rather than repeated.
  • Although a limit of 500 words is suggested, longer Materials and Methods sections are acceptable as long as the overall word count does not exceed that stipulated for the corresponding manuscript category. Expanded Materials and Methods can be published online only (see "Online Data Supplements").
  • The following information should be included either in the print version Materials and Methods section, or in an Online Data Supplement: For animals used in experiments, state the species, strain, number used, and other pertinent descriptive characteristics. When describing surgical procedures on animals, identify the preanesthetic and anesthetic agents used and state the amount or concentration and the route and frequency of administration for each. The use of paralytic agents, such as curare or succinylcholine, is not an acceptable substitute for anesthetics. For other invasive procedures on animals, report the analgesic or tranquilizing drugs used. If none were used, provide justification for such exclusion. Generic names of drugs must be given. Manuscripts that describe studies on humans must indicate that the study was approved by an institutional review committee and that the subjects gave informed consent. Please provide sex-specific and/or racial/ethnic-specific data, when appropriate, in describing outcomes of epidemiologic analyses or clinical trials; or specifically state that no sex-based or racial/ethnic-based differences were present. Reports of studies on both animals and humans must indicate that the procedures followed were in accordance with institutional guidelines.
  • Manuscripts that feature gene chip array technology and other high-throughput genomics methods must meet the following criteria (for details see Circ Res 2001;89:469):
    1. The salient results of the genomic screen must be confirmed by complementary methods (such as Northern blot analysis), for selected transcripts of greatest relevance or interest.
    2. The principal findings must be reproducible, ie, confirmed with multiple chips using multiple sources of RNA.

    Online Data Supplements

  • This optional section provides an opportunity for authors to present supporting materials to the manuscript. An Online Data Supplement is independent from the manuscript and appears ONLY online.
  • Online Data Supplement undergoes peer review and must be submitted simultaneously with the original manuscript submission.
  • With the exception of video files and large datasets in Excel file format, authors must compile all Online Data supplement materials into one (1) PDF file.
  • Online Data Supplement may consist of any of the following, in any combination:
    1. Expanded Materials and Methods (PDF file format)
    2. Additional Figures and supporting information (PDF file format)
    3. Additional Tables and supporting information (PDF or Excel file formats)
    4. Video Files (acceptable file formats are: avi, mov, mpg at max 10 MB; if larger, create and upload zip file)
  • If citations are made in an Online Data Supplement, the Online Data Supplement must contain its own independent Reference Section with references numbered sequentially, beginning with Reference 1, even if some of these references duplicate those in the print version.
  • The Editorial Office is not responsible for extracting Online Data Supplement material from print manuscript material.
  • The Table of Contents highlights articles that contain Online Data Supplements by a paperclip and/or video camera icon, and lists the URL where supplements can be accessed.

    • Acknowledgments Section

  • The Acknowledgment section should include any personal thanks to individuals who assisted in the preparation of the manuscript.
  • Authors must provide written permission from all individuals who are listed in the “Acknowledgments” section of the manuscript, because readers may infer their endorsement of data and conclusions.
  • The corresponding author must ensure that (1) all persons who have made substantial contributions in the manuscript (eg, data collection, analysis, or writing or editing assistance), but who do not fulfill authorship criteria, are named with their specific contributions in the Acknowledgments section of the manuscript; (2) all persons named in the Acknowledgments section have provided the corresponding author with written permission to be named in the manuscript; and (3) if an Acknowledgments section is not included, no other persons have made substantial contributions to this manuscript.

    • Sources of Funding Section

  • The Sources of Funding section should include all sources of research support, including commercial or institutional support, plus substantial contributions of individuals.
  • Authors must completely spell out all grant funding agency abbreviations, with the exception of NIH.

    • Disclosures Section

  • In the Disclosures Section, authors must disclose any and all relationships that could be perceived as real or apparent conflict(s) of interest. If authors have nothing to disclose, authors must state "None." Conflicts of interest pertain to relationships with and/or ownership interests in pharmaceutical companies, biomedical device manufacturers, or other corporations whose products or services are related to the subject matter of the article. Relationships include, but are not limited to, employment by an industrial concern, ownership of stock, membership on a standing advisory council or committee, being on the board of directors, or being publicly associated with the company or its products. Ownership interest includes any stock, stock option, partnership, membership or other equity position in an entity regardless of the form of the entity, or any option or right to acquire such position, and any rights in any patent or other intellectual property. Other areas of real or perceived conflict of interest could include receiving honoraria or consulting fees or receiving grants or funds from such corporations or individuals representing such corporations.

    • References

  • References are included in the word limit.
  • References must conform to journal style. Consult the American Medical Association Manual of Style, 9th ed, Baltimore, Md, Williams & Wilkins, 1998.
  • Example of Journal Reference Style:
    Patel VA, Zhang Q-J, Siddle K, Soos MA, Goddard M, Weissberg PL, Bennett MR. Defect in insulin-like growth factor-1 survival mechanism in atherosclerotic plaque-derived vascular smooth muscle cells is mediated by reduced surface binding and signaling. Circ Res. 2001;88:895-902.

  • Authors must ensure accuracy of reference data. Verify all entries against original sources.
  • All authors must be listed in references. Shortened lists of author names followed by "et al" must be replaced with complete information.
  • Cite references in numerical order according to first mention in text.
  • Personal communications, unpublished observations, and submitted manuscripts are not legitimate references and must be cited in the text as "(unpublished data, [year])."
  • Abstracts may be cited only if they are the sole source and must be identified in the reference as "Abstract."
  • "In-press" citations must be accepted for publication and must include the name of the journal or book publisher. Note that copies of all such articles must be submitted with the manuscript at the time of original submission.

    • Figures

  • Acceptable electronic figure file formats: TIFF, EPS, Photoshop, PDF, PowerPoint.
  • The use of digital media for image acquisition and processing introduces the potential for inadvertent distortion of data. To prevent such distortion, the following guiding principles should be followed:
    1. Data should neither be added to, nor removed from, an image by digital manipulation.
    2. Figures assembled from multiple images must indicate the separation of the parts by lines.
    3. Linear adjustment of contrast, brightness or color must be applied equally to all parts of an entire image.
    4. Deviations from the above, including nonlinear adjustments, must be indicated in the figure legend along with a description of the processing software used.
    5. If questions arise, the authors must be prepared to submit the original, unaltered files from which the submitted figures were derived.
  • Additional figures may be submitted for online-only publication as an Online Data Supplement, subject to peer review (see "Online Data Supplements").
  • Figures may be black-and-white line drawings, graphs, color illustrations, or halftones (gel blots/stains). Authors are responsible for the cost of printing color illustrations.
  • Label the front of the figure with the figure number, bars, panels, etc. in a simple font that is uniform in size and style.
  • Authors are strongly encouraged to limit the number of panels per figure to 4. Excessive panels per figure are strongly discouraged and may result in returning the paper to the authors for revision before submission is allowed.
  • Limit white space between all panels and within each panel.
  • Supply a scale bar with photomicrographs.
  • Figure legend copy must be double spaced. Figure legends are included in the word limit.
  • Abbreviations/symbols used in any figure but not already defined in the main text must be defined in the figure legend.

    • Tables

  • Include table(s) in the main manuscript document as text, not as an image. Table(s) are included in the word limit.
  • Supply a brief, informative title for each table numbered using Arabic numerals.
  • Table text must be consistent in size and style with main manuscript text.
  • Supply brief column headings and indicate footnotes using unique symbols.
  • Use only horizontal borders above and below the column headings and at the bottom of the table. Use extra space to delineate rows and columns.
  • Abbreviations/symbols used in any table but not already defined in the main text must be defined in the table or table legend.

    • Cover Figures

  • The editors encourage submission of color images for consideration as potential cover figures. These may be submitted online initially or upon revision, or emailed to the Editorial Office immediately after acceptance.
  • Authors should include a figure legend for the potential cover figure.
  • Cover figures should not duplicate images already in the article. Cover figure submissions may be altered or enhanced versions of an original figure within the manuscript. Alterations and enhancements should be explained in the cover figure legend.
  • Do not submit schematic figures or flowcharts.
  • Acceptable electronic cover figure file formats: TIFF, EPS, Photoshop, PDF, PowerPoint.

    • 3. MANUSCRIPT REVISIONS

  • Current policy allows for a maximum of ONE revision per article.
  • Time limit for receipt of revisions is dated from last decision letter:
  • Original Contributions and Research Commentaries-- 90 day revision time
  • MiniReviews and Reviews-- 30 day revision time
  • Reports and UltraRapid Communications-- 10 day revision time (limited to minor clarifications and additions)
  • If a revision is not received within the specified time limit, the manuscript is assigned a new number. In such cases, every effort will be made to retain the original reviewers.
  • Extensions for revisions cannot be granted.
  • Number each page in the top right corner, using your manuscript number followed by /R1 to denote a first revision.
  • In your written response to the reviewers' comments, give the exact page number(s), paragraph(s), and line number(s) where each revision was made.
  • Authors may upload their response to reviewers as a supplemental file.

    • 4. JOURNAL POLICIES

    Editorial Conflict-of-Interest Policy.

  • Original manuscripts authored or coauthored by the Editor in Chief and/or any of the Associate Editors are handled by a Consulting Editor, who makes all decisions about the manuscript (including choice of referees and ultimate acceptance or rejection). The entire process is handled confidentially. All manuscripts submitted from the Editor's home institution are also handled entirely by a Consulting Editor. The Editor in Chief and/or Associate Editors may additionally, from time to time, refer a manuscript to a Consulting Editor to avoid a real or reasonably perceived conflict of interest. Ethical Conduct Policy

    • Prior Publication and Overlapping Work

  • By virtue of submitting an article for consideration by Circulation Research, the authors certify that the manuscript and the material in the manuscript have not been published and are not being considered for publication elsewhere in whole or in part in any language, including publicly accessible Web sites or e-print servers, except as an abstract.
  • The authors also certify that any and all other work in preparation, submitted, in press, or published that is potentially overlapping either in the actual data presented or in the conceptual approach is enclosed along with the original submission. Any material within the manuscript that has appeared elsewhere must be cross-referenced and permission to use or adapt the material must be received in the editorial office in writing from the copyright holder.
  • If some or all of the work in the manuscript has been published or submitted in abstract form, and/or overlapping data exists, the following rules apply:
    1. The published or submitted abstract must accompany the submitted manuscript.
    2. The abstract in question cannot be longer than 400 words.
    3. The abstract cannot itself have been referenced in MEDLINE or PubMed.
    4. The potentially overlapping work and a separate explanation of the nature of any possible overlap with the submitted manuscript must accompany the submitted manuscript.

    Data Deposition and Data Availability

  • Guidelines for Deposition of Protein and Nucleic Acid Data:
    1. Preparation of Data: Submitted data should follow the MIAME checklist (for more information see http://www.mged.org/Workgroups/MIAME/miame_checklist.html).
    2. Accessibility of Data: Authors of papers that include genomic, proteomic, or other high-throughput data are required to make their data easily accessible for the reviewers and the editors during the review process. You may submit your data to the NCBI gene expression and hybridization array data repository (GEO, http://www.ncbi.nlm.nih.gov/geo/) and provide the GEO accession number; or, you may provide a link to a secure or publicly accessible website which hosts the data. Prior to publication, the data must be submitted and an accession number obtained. Access to the information in the database must be available at the time of publication. GEO has a web-based submission route, suitable for a small number of samples, or a batch submission tool (called SOFT). GEO is accessible from http://www.ncbi.nlm.nih.gov/geo/. Submission FAQ is at http://www.ncbi.nlm.nih.gov/projects/geo/info/faq.html.
    3. Newly reported nucleotide or protein sequences must be deposited in GenBank (http://www.ncbi.nlm.nih.gov/Genbank/index.html), EMBL (http://www.ebi.ac.uk), or DNA Data Bank of Japan (http://www.ddbj.nig.ac.jp) databases, and an accession number must be obtained. Access to the information in the database must be available at the time of publication. Authors are responsible for arranging release of data at the time of publication. The authors must also provide a statement in the manuscript that this sequence has been scanned against the database and all sequences with significant relatedness to the new sequence identified (and their accession numbers included in the text of the manuscript).
  • Clinical trials should be registered with a publicly accessible clinical trial registry, such as http://www.clinicaltrials.gov. Registration number and registry URL should be supplied when submitting the manuscript online. A clinical trial is defined as any research study that prospectively assigns human participants or groups of humans to one or more health-related interventions to evaluate the effects on health outcomes. Studies that are designed for other purposes, such as to study pharmacokinetics or major toxicity (e.g., phase 1 trials), are exempt.
  • Randomized clinical trial reports should also comply with the Consolidated Standards of Reporting Trials (CONSORT). Authors should refer to the CONSORT statement (www.consort-statement.org) for a checklist of items describing how the trial was designed, analyzed, and interpreted, and a flow diagram displaying the progress of all participants through the trial.
  • Materials and Data Availability: To allow others to replicate and build on work published in Circulation Research, we recommend that authors make materials, data, and associated protocols available to readers. Authors must disclose upon submission of the manuscript any restrictions on the availability of materials or information. We recommend that authors make unique materials (e.g. cloned DNAs; antibodies; bacterial, animal or plant cells; viruses; computer programs) promptly available on request by qualified researchers for their own use. It is reasonable for authors to charge a modest amount to cover the cost of preparing and shipping the requested materials.

    • Deposit of Manuscripts to Publicly Accessible Repositories (e.g. PubMed Central)

  • All rights, title, interest and copyright ownership of a manuscript accepted for publication in Circulation Research, a journal of the American Heart Association, are conveyed by the author(s) to the American Heart Association.
  • If a manuscript is supported in whole or part by a funding body, such as the NIH, then authors are authorized to deposit the manuscript in the funding body’s designated repository, e.g. PubMed Central (PMC).
  • Authors MUST specify at time of manuscript deposit that the manuscript be made public NO EARLIER THAN 6 MONTHS AFTER THE PRINT ISSUE PUBLICATION DATE.
  • For PubMed Central, authors must deposit the final, accepted version of the manuscript prior to any copyediting by the publisher. Further details regarding PubMed Central deposit requirements are available online at http://nihms.nih.gov
  • Before depositing the accepted manuscript to any repository, Authors MUST include the following disclosure on the title page of the manuscript prior to the abstract section: This is an un-copyedited author manuscript accepted for publication in Circulation Research, copyright The American Heart Association. This may not be duplicated or reproduced, other than for personal use or within the “Fair Use of Copyrighted Materials” (section 107, title 17, U.S. Code) without prior permission of the copyright owner, The American Heart Association. The final copyedited article, which is the version of record, can be found at http://circres.ahajournals.org/. The American Heart Association disclaims any responsibility or liability for errors or omissions in this version of the manuscript or in any version derived from it by the National Institutes of Health or other parties.
  • For more information regarding author rights and responsibilities, please see the AHA Authorship Responsibility and Copyright Transfer Agreement Form. Permissions and Rights FAQ are available online at http://www.ahajournals.org/rights

    • Embargo Policy

  • Articles published in Circulation Research cannot be discussed by journalists or presented in other public media before 4:00 PM EST on the day before the cover date of the issue, except when articles are posted online ahead of the print version (Online First). In such cases, the embargo date will be 4:00 PM EST on the day of online posting. Although the Editorial Office will endeavor to notify authors of the anticipated online publication date, neither the Editorial Office nor the AHA will be responsible for any consequences of early online posting with regard to intellectual property rights. To safeguard their intellectual property, authors should ensure that appropriate reports of invention and patent applications have been filed before the manuscript is accepted.
  • Prior presentations at scientific meetings are allowed, but the authors should be aware that such presentations may undermine their intellectual property rights. Questions regarding the embargo policy should be directed to Cathy Lewis, Senior Manager, Consumer Health News, Corporate & Media Communications, AHA National Center, 7272 Greenville Avenue, Dallas, TX 75231-4596.
