The Journal of Cardiovascular and Thoracic Research accepts the following categories of articles:
Commentaries by the Editor, Associate Editors, and other scientists and experts reflect the opinion of the periodical and provide general interest to our readers. Editorials are by invitation only. Total manuscript length should be limited to approximately 1,000 words.
Commentaries may contain critical comments on an original paper recently published in most of cases. It should not present original, unpublished data, and ? may present material of general interest to the readership. Total manuscript length should be limited to approximately 700 words with less than three authors and 6 references.
These may describe original clinical or laboratory research in any area related to cardiovascular science. Manuscripts should contain an abstract of maximum 250 words, introduction, methods and materials, results and discussion, limitations of study, conclusion and acknowledgement. Total manuscript should be limited to approximately 5000 words. Maximum number of tables and figures (combined) is 8. Maximum number of references is 40.
Brief communications are short research articles presenting findings in any area related to cardiovascular research. This type of manuscripts should contain at most 2,000 words, including the abstract, introduction, materials and methods, results, discussion, and references. Maximum number (combined) of tables and figures is 4 with maximum reference number of 20.
Case reports present informative materials relative to clinical situations. They may describe a diagnostic dilemma, a rare or interesting clinical situation, new protocols for treatments, or a newly recognized condition or complication. The length of the manuscript should not exceed 1200 words. Maximum number of figures and tables (combined) is 4. Article format is an abstract of maximum 150 words followed by a brief introduction, a description of the case (case history) and discussion.

are typically by invitation only through the editorial board. However we may
occasionally consider uninvited reviews and meta analyses if the author(s) have
previous contribution on the subject. They should not exceed 5000 words with a
maximum of 50 references and 8 table or figures.
Submission of manuscripts
All authors should register at http://jcvtr.tbzmed.ac.ir/Account and then follow the easy steps for submission. 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. Our goal is to provide the reader primary investigation, scholarly review, and opinion concerning the practice of cardiovascular medicine.
An initial review for adherence to submission instruction and scientific quality will be provided by the editorial team within 2 weeks of submission and those manuscripts found to be of proper quality will be subsequently considered for a full review process performed by highly qualified reviewers. Pre-submission inquiries are not required and authors should submit their manuscripts based on the guidelines listed in the Instructions to Authors.
Guidelines for Clinical Trials
Manuscripts submitted to the Journal reporting the results of a randomized clinical trial must include the registration site and the registration number in the Methods section in accordance with the Clinical Trial Registration Statement from the International Committee of Medical Journal Editors. Clinical trial reports should also comply with the Consolidated Standards of Reporting Trials (CONSORT) and include a flow diagram presenting the enrollment, intervention allocation, follow-up, and data analysis with number of subjects for each (http://www.consort-statement.org/?o=1011 )
- Correct preparation of the manuscript by the authors will expedite the reviewing and publication procedures. Following the instructions for online submission, the article, including all tables, should be formatted in Microsoft Word.
- The order of the manuscript should be as following: title page, abstract, introduction, material and methods, results, discussion, acknowledgments (including sources of funding and etc.), conflict of interests, ethical issues, references and tables.
- Figure legends should be placed on the same page as the Figure to facilitate the review process.
- Style. Manuscripts must conform to acceptable English usage. Standard abbreviations should be used consistently throughout the article. Abbreviations should be spelled out the first time they appear in the text and followed in parentheses by the abbreviation. Consult the latest editions of The Chicago Manual of Style or the AMA's Manual of Style, 9th edition, for current usage.
- Title page. The title page should be typed double-spaced and include the title, authors' full names, institutional affiliations and location, and a short, abbreviated title of 40 characters or fewer. Designate one author (provide address, business telephone and fax numbers, and e-mail address) to receive correspondence, galley proofs, and reprint requests.
- Abstract. Each article must include a structured abstract of no more than 250 words. Use the following headings for sections of the abstract: Introduction, Methods, Results, Conclusion. For review articles and trial designs, instead of a structured abstract, please provide a summary abstract paragraph (maximum word count 250 words). Do not include references and minimize the use of abbreviation.
- 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 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.
- 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 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
- 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, Encapsulated PostScript (EPS) for illustrations or diagrams, Tagged Image File Format (TIFF), EPS, or PS. Files prepared with Adobe Illustrator, Corel Draw or Adobe Photoshop should be uploaded in these native file formats.
- 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.
Acceptable digital formats are:
- Corel Draw
- Adobe Illustrator
- Unlocked PDFs created from a vector program
- Microsoft PowerPoint, Excel, and Word as long as graphs are not placed into these programs as rasterized images.

Citing in the text
- Cite references in the text sequentially in the Vancouver numbering style, as a superscripted number after 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.
