Preparing a Manuscript

Article types

The Editor-in-Chief and members of the Journal's Editorial Board and independent experts will review most manuscripts submitted to RCM. However, the Editor-in-Chief and the Editors reserve the right to reject a manuscript without conducting an in-depth review if they feel that the manuscript is "out of scope" or it does not meet the minimal acceptance criteria for publication in RCM.

We accept 10 types of article as follows:

Original Research

    This is the most common type of journal manuscript. It may be called an Original Article, Research Article, or just Article, depending on the journal. The Original Research format is suitable for many different fields and different types of studies. It includes full Introduction, Methods, Results, and Conclusion sections.


    Review Articles provide a comprehensive summary of research on a certain topic, and a perspective on the state of the field and where it is heading. They are often written by leaders in a particular discipline after invitation from the editors of a journal. Reviews are often widely read (for example, by researchers looking for a full introduction to a field) and highly cited. Reviews commonly should be more than 5000 words and should cite approximately 100 primary research articles.

Systematic review

    Systematic review is a type of literature review that uses systematic methods to collect secondary data, critically appraise research studies, and synthesize findings qualitatively or quantitatively.

Short communication

    Short Communications are short papers that present preliminary research addressing an important area of research.

Case Report

    In medicine, a case report is a detailed report of the symptoms, signs, diagnosis, treatment, and follow-up of an individual patient. Case reports may contain a demographic profile of the patient, but usually describe an unusual or novel occurrence. Some case reports also contain a literature review of other reported cases. Case reports are professional narratives that provide feedback on clinical practice guidelines and offer a framework for early signals of effectiveness, adverse events, and cost. They can be shared for medical, scientific, or educational purposes.

Letter to the Editor

   We welcome readers to submit formal comments on the content of articles published in Cardiovascular Medicine. Such comments should provide constructive scientific remarks. Readers may submit these comments as a Letter to the Editor, which should be concise, no more than 500 words, and we will transmit them to the author(s) of the commented-upon paper for their optional reply.

News and Views 

     News contain updates and newsworthy discussion pieces relevant to the journal's scope.

Conference/Meeting Abstract Proceedings 

    Conference/Meeting Abstract Proceedings publish the proceedings from international conferences or selected abstract presented at a meeting. All enquiries regarding the possible publication of Meeting Proceedings should be sent to the Editor via the Editorial offices.


    Editorials are opinion articles from the editor or an invited author. Editorials, when submitted by an invited contributor, may be used to introduce the subject being brought into focus in a special issue or thematic section. Editorials may comment on one or more articles in the same issue of RCM, or on an area of current interest in cardiovascular medicine. They should be brief and focused. Editorials should not exceed 1,000 words, 15 references, and 1 table or figure. Editorials may have a maximum of 3 authors. The body of the Editorial can be continuous text or divided into subsections. There is no abstract. Editorials on topics of current interest are welcome but should be discussed with the Editor-in-Chief before submission. Acceptance will reside with the editors. Please contact the Editorial Office directly if you want to write an editorial.

Organization of the Manuscript

☆ Times New Roman. Font size 12. Spacing 1.5. Alignment Justified.

☆ The first line indents 2 characters of a new paragraph.

☆ Sub-headings and general headings should be presented in lower case letters (not capitals).

☆ Use British English or American English spellings throughout your manuscript, but not both.

☆ Do not use page breaks in your manuscript.

☆ Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading.

    Please note: editable files are required for processing in production. If your manuscript contains any non-editable files (such as PDFs) you will be required to re-submit an editable file when you submit your revised manuscript, or after editorial acceptance in case no revision is necessary.

Manuscripts must include the following sections in the order listed

Title Page

    The first page of the manuscript should be a title page with the following:

* Title

    The title of the manuscript in sentence case. No abbreviations other than gene names or in common use.

Full names, email address and affiliations including postal codes of all authors

    Authors affiliations should reflect where their primary contribution to the research was made. Affiliations of the authors indicated by numbers (not symbols), Equal contribution indicated by ?.

Corresponding author and corresponding email address

    Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. This responsibility includes answering any future queries about Methodology and Materials. RCM allows up to two corresponding authors; when two are listed, no priority is given to either. The submitting author is required a corresponding author. Please provided the corresponding author Name, full postal address, including street number and name, and institutional email address.

Conflict of interest statement

    This section is required for all papers. If there are no interests to declare, please use the following wording: "The authors declare no conflicts of interest statement" or “The author declares no conflicts of interests“ The text in this section should match the text provided in the Declaration of Interests form in the publishing agreement. More about the competing interests policies.


    Use this section to acknowledge contributions from non-authors, list funding sources. As this section contains important information and many funding bodies require inclusion of grant numbers here, please check it carefully.

Abstract (350 words maximum)

    The Abstract should not exceed 350 words. Abbreviations that appear once only, should be defined in full, unless they correspond to a gene name. If abbreviations appear more than once, the definition should be provided once, and then subsequently used throughout the abstract. Please do not cite references, figures or tables, website, equations or other graphical elements included. Original research, systematic reviews, and meta-analyses require structured abstracts. 


    Immediately after the abstract, provide 3-10 keywords, using avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of').


    References should be identified in the text by Arabic numerals and numbered in the order cited. The reference list should be limited to only those citations essential to the presentation. Before submission of the manuscript, authors should verify the accuracy of all references and check that all references have been cited in the text. If a reference has five or fewer authors, list all the author names in the references entry. If a reference has six or more authors, display the first six authors followed by et al. The reference should include all the pages.
Reference examples:

    Use the [number] for the references in the text, for example, if there is only one reference, use [1]; if two, use [1, 2]; and if three or more, use [1-3].

Figure Legends

Legends should be included in the submitted manuscript as a separate section. Each figure legend should have a brief title that describes the entire figure without citing specific panels, followed by a description of each panel. In writing the figure title, we encourage you to re-use the subheadings of the Results section to make the relationship clear. For any figures presenting pooled data, the measures should be defined in the figure legends (for example, "Data are represented as mean ± SEM."). Each legend should refer to any supporting items in the Supplemental Information (e.g., "See also Fig. S1.").


Equations and Symbols

    Manuscripts with many mathematical characters and equations should be prepared using MathType version 6.0 or higher or word-processing tools such as Word’s Equation Editor.

Abbreviations and Units

    IF abbreviations appear more than once, the definition should be provided once, and then subsequently used throughout the text. Symbols for physical units should be restricted to System International units (SI) should be used without definition. Generic names of drugs and pesticides are preferred; if trade names are used, the generic name should be given at first mention. The doses of the drugs should be given as unit weight/unit body weight, e.g. mmol/kg or mg/kg. Genus and species names should be in italics.

Please use the standard mathematical notation for formulae, symbols, etc.

· Always use a leading zero (0) before decimal points: 0.5 NOT .5.

·  Decimal points should use a full stop/period (.) NOT a comma (,).

· A space should be inserted before measurement units: 132 bp NOT 132bp, 5 mm NOT 5mm, 1 h NOT 1h

· Symbols for genes should be italicized(p53), whereas symbols for proteins are not italicized (p53). Gene names that are written out in full are not italicized (tumor protein 53).


Original data: The editors reserve the right to request authors to provided any original, unprocessed data in the submission, review, or publication process, including after publication.

Image manipulation: All images in manuscripts accepted for publication will be production delays or revocation of acceptance which inconsistent with the following guidelines:

· Do not enhance, occlude, move, remove or introduce specific features in the image

· Do not combination figures using images taken from different parts of the same gel or from different gels.

· Do not arise image duplication in submission, including retroflexion. color balance.

File format


    For vector graphics, the preferred format is TIF, PNG, JPG without layers and preferably using Lempel-Ziv-Welch (LZW) compression as it does not reduce image quality.

    JPEG (only if originally saved at the highest quality).


Images imported or copy pasted into Word or PowerPoint.

BMP, GIF, PCT, PNG or low quality JPEG files originally saved at low quality.


Image size is measured in centimeters or inches.

Create your figures at the size (width) at which they will be printed:

* 8.00 cm (3.15 in) wide for a single-column figure

* 17.00 cm (6.70 in) maximum for a double-column (full page width) figure

* Maximum height 20.00 cm (7.87 in)

Empty white space surrounding a figure should NOT be included when calculating image size.

Images should, therefore, be cropped (cut) as close to the outside edges of the figure as possible.


Minimum resolution for all figures is 300 dpi. For figures that contain both photographs and line art or text, 600 dpi is highly recommended. Figures containing only black and white elements (line art, no color, and no gray) should be 1,000 dpi. Maximum figure size is 7 in wide x 9 in high (17.5 x 22.8 cm) at the correct resolution.

Note: Resolution settings in many software programs (including vector programs such as Illustrator) default to low resolution (72 dpi) when placing images. Be certain to set resolution prior to beginning your figure layout.

Color mode

Use RGB as this will offer the best reproduction of your data in the final PDF version of your article on screen. CMYK mode is also acceptable. Fluorescence images must be submitted for publication in color. Black and white figures and line art: grey scale mode or RGB mode.

Combination figures with color images and line art: RGB mode.

Figure name

Figures are cited sequentially in the text using Arabic numerals (for example, Fig. 1).

Type appearing within figures (axis labels, for example) is in Arial or a similar typeface and is of sufficient size and contrast to retain clarity if reduced in size. Avoid use of bold type in figure labels.

Figure labels

Labels should be sized in proportion to the image, sharp, and clearly legible.

Type appearing within figures (axis labels, for example) is in Arial or a similar typeface and is of sufficient size and contrast to retain clarity if reduced in size. Avoid use of bold type in figure labels.

Figures may be divided into separate sections. Each section may be saved as a separate file (clearly indicated in file name) or included together in one file (with parts clearly labeled). Separate parts of a figure should be labeled using just A, B, C, NOT a, b ,c 1A, 1B, 1C. Place A, B, C to the top left of each section of the figure. And each section of the figure should be well-arranged.

The labels should be of the same font and size in all figures. Also, the numbering should be of the same font and size in all figures.

Labels should be evenly spaced and aligned, easy to see (including exponential numbers around figure axes), and NOT faded, broken, or distorted by JPG compression artifact.

If any magnification is used in the photographs, indicate this by using scale bars within the figures themselves.

Avoid gratuitous use of color for decorative effect, boxes around graphs and figures, and small type and symbols on large graphs; avoid pairing red and green in graphs to ensure legibility for color-blind readers. Whenever possible, do not place labels over any part of a color figure. Do not include tabular material within figures.

Do NOT use light grey color lines or labels.

There must be strong contrast between labels and their background (e.g., labels placed over shaded bar graphs should be in a color that stands out against the shading, NOT blend in with it). Whenever possible, labels should be placed in black font on a white background. Consider using a black label with a white stroke applied to create contrast.

The first letter of each phrase, NOT each word, should be capitalized [e.g., ‘Overall survival (months)’ not ‘Overall Survival (Months)’ and not ‘overall survival (months)]’.

Do not include titles or captions within your illustrations.


Please submit tables as editable text and not as images. Tables can be placed either next to the relevant text in the article, or on separate page(s) at the end. The data presented in tables do not duplicate results described elsewhere in the article. Tables with sections (for example, Table 1A, 1B, 1C) are not acceptable. For each table, please supply a table caption (title) explaining the contents of the table. Place any table notes below the table body. If bold or italic font is used within a table to indicate some feature of the data, please give an explanation of its usage in the legend. All abbreviations within a table must be defined in the table legend or footnotes. Footnotes should be listed with superscript lowercase letters, beginning with “a.” Footnotes may not be listed with numbers or symbols.
