Submission of manuscripts

General instructions for submissions

Authors can submit a document via using the link "Submit Your Paper" on the Journal's homepage. All authors should register at http://jcvtr.tbzmed.ac.ir/. JCVTR no longer accepts submissions by mail. The Journal will consider for publication suitable articles on topics pertaining to the broad discipline of cardiovascular disease. Only papers written in English are considered. Manuscripts should be professionally edited before submission. Our goal is to provide the primary reader investigation, scholarly review, and opinion concerning cardiovascular medicine.

Review Process

The editorial team will provide an initial review for adherence to submission instruction and scientific quality within two weeks of submission, and those manuscripts found to be of qualified will be subsequently considered for a full review process performed by highly skilled reviewers. After receiving reviewers' comments, the Editor/s-in-chief make a final decision. Pre- submission inquiries are not required, and authors should submit their manuscripts based on the guidelines listed in the Instructions to Authors. The journal subjects any papers to plagiarism-detection software. At any stage of peer-review, publication, or post-publication, if plagiarism is detected the manuscript may be rejected, corrected, or retracted, as appropriate, and we reserve the right to inform the authors' institutions about any plagiarism detected.

Abbreviations

Abbreviations and acronyms should be explained at the first time they are used within the abstract and again in the main text and then used throughout the remainder of the manuscript. Please consider adhering to this convention.

Drug Names

Generic names should, in general, be used. If an author so desires, brand names may be inserted in parentheses.

Formulas

  • Equations should be typed only in MathType (Download the software from http://www.dessci.com/en/products/mathtype/).
  • If you have already composed your paper in Microsoft Word and used its built-in equation editing tool, the equations will become unusable during the typesetting process. To resolve this problem, re-key your equations using MathType.
  • Graphical objects should not be used.
  • Make sure that your equations are editable.
  • Long equations should be set off from the text and numbered sequentially. You may refer to the equations in the next references by their number (e.g., "Eq. 1," "Eqs. 2 and 3").
  • If using many equations or schemes is unavoidable, they can be collected in a table of equations and be shot as a framed figure to avoid typesetting errors.

Tables

  • Should be prepared left to right and cell-based (i.e., created in Word with the Tables tool). And captions should be provided in the end of the manuscript.
  • Be editable and presented in a vertical orientation, and upright on the page, not on sideways.
  • Be prepared with real rows and columns and not aligned with tabs, returns, or spaces.
  • Multi-part tables with varying numbers of columns or multiple footnotes should be organized as separate tables.
  • Be plain with NO colors, shading, or graphics.
  • Should not contain inserted text boxes, tables within tables or cells within cells.
  • Should be cited in numerical order upon their first mention.
  • Symbols and abbreviations should be defined immediately below the table, followed by essential brief description

Figures

  • All images must be uploaded as separate files.
  • They must be cited within the main text in numerical order and legends should be provided in the end of the manuscript and not appear on the figures.
  • Figures must be prepared in one of the following formats: Adobe Portable Document Format (PDF) for photography or microscopy, Tagged Image File Format (TIFF) or JPEG.
  • All digitized images submitted with the manuscript must be of high quality; that is, resolutions of at least 600 dpi for color figures, 600 dpi for grayscales and 1200 dpi for line arts.
  • Histograms should be prepared in a simple, two-dimensional format, with no background grid.
  • Make sure that any specific patient/hospital details are removed or blacked out (e.g., X-rays, MRI scans, etc).
  • If photographs of patients are used, they should not be identifiable. However, do not use a black bar to obscure a patient’s identity.
  • Original data from which the images were prepared should be available, as the editors may request to see these data (e.g., Office, SPSS and other line art images).
  • Lettering in figures (e.g., labeling of axes) should be in lower-case type, with the first letter capitalized and no full stop. All text should be in a sans-serif typeface, preferably Arial.
  • Avoid using the touch-up tools, such as cloning and healing tools in Photoshop, or any feature that deliberately obscures manipulations.
  • Graphics downloaded from Web pages should not be used.
  • Submit multi-panel figures (with labeled parts as a,b,c,d,..) as one file.
  • Please remember that Vector drawing data is absent from these files: png, jpeg, tiff, or bmp. Subsequently resaving any of these files as a PDF or EPS will not produce a vector drawing in these files. Please supply the original EPS, ai, or PDF file versions of artwork.

References

  • Arrange references as a simple list at the end of your manuscript based on our Endnote style (Download JCVTR EndNote Style).
  • Authors are responsible for the accuracy of cited references, and these should be checked before the manuscript is submitted.
  • Do not use linked fields (produced by EndNote and similar programs). Please use the one-click button provided by EndNote to remove EndNote codes before saving your file.
  • Only one publication can be listed for each number.
  • Published conference abstracts, numbered patents, and preprints on recognized servers may be included in reference lists, but text, grant details, and acknowledgments may not.

Citing in the text

  • Cite references in the text sequentially in the Vancouver numbering style, as a superscripted number after the nearest punctuation mark. For example …as reported by Saito and colleagues.13
  • Two references are cited with a comma and no space. Three or more consecutive references are cited in a range with dashes.
  • References in tables, figures, and panels should be in numerical order according to where the item is cited in the text.
  • Reference numbers should NOT be cited in parentheses.
  • Please note that if references are not cited in order the manuscript may be returned for amendment before it is passed on to the Editor for assessment.
  • Only papers published or in press should be included in the reference list. Personal communications or unpublished data must be cited in parentheses in the text with the name(s) of the source(s) and the year. Authors should request permission from the source to cite unpublished data.

In reference list

  • List the surnames and initials of first names of all authors if there are 6 or fewer; otherwise, list the first 6 and add ‘et al.’ Use one space only between words up to the year and then no spaces. The journal-title should be in bold and abbreviated according to the style of PubMed. If the journal is not listed in PubMed, then it should be written out in full. Check journal abbreviations using PubMed.
