Instruction to authors

The aim of the journal is to facilitate medical education through the publication and dissemination of quality original papers and promote medical knowledge to enable cardiologist to keep up to date with developments in their specialty, particularly those which may impact upon their practice. The journal also reports on Sudan Heart Society activities such as symposia, conferences and continuous medical education programs.

Manuscripts containing original material are accepted for consideration if neither the article nor any part of its essential substance, tables, or figures has been or will be published or submitted elsewhere before appearing in the Journal. Review articles, original papers, case reports, cardiology images, clinical Quiz, commentaries and letter to the editor are accepted.

Submission Guidelines

Papers should be submitted online to SHJ website: Text should be typed double spaced in Microsoft Word Times New Roman font 12. Main and subheadings should be typed in bold letters. Please make sure that spelling mistakes are avoided by using the spell checker incorporated in Microsoft Word

Original Articles

Clinical papers should not be more than 5,000 words in length, with accompanying data and images as appropriate. Accompanying, relevant images are welcomed for each type of paper provided copyright clearance has been obtained by the authors from the publishers of the work. Figures and Tables should not exceed a total of 8 and up to 40 references may be included. Articles should follow the standard reporting of manuscript: title page, abstract, introduction, methods including statistical methods, results and discussion.

Please write as concisely as possible and include a word count. Appropriate subheadings should be used to divide the text. A separate title page should be provided, to include: acknowledgement, funding and conflict of interest should be addressed.

The title should be concise but informative. Authors’ names, job titles and places of employment should be clearly stated. The name and contact details (address, email, tel. no.) of the corresponding author. Clinical papers should include a structured abstract of not more than 250 words. It should consist of four paragraphs, labeled Background, Methods, Results, and Conclusions. They should briefly describe, respectively, the problem being addressed in the study, how the study was performed, the salient results, and what the authors conclude from the results. Up to six key words relevant to the article’s content should be included.


Provide a context or background for the study (that is, the nature of the problem and its significance). State the specific purpose or research objective of, or hypothesis tested by, the study or observation. Cite only directly pertinent references, and do not include data or conclusions from the work being reported.


The guiding principle of the Methods section should be clarity about how and why a study was done in a particular way. The Methods section should aim to be sufficiently detailed such that others with access to the data would be able to reproduce the results. In general, the section should include only information that was available at the time the plan or protocol for the study was being written; all information obtained during the study belongs in the Results section and that inclusion and exclusion criteria be stated. The Methods section should include a statement indicating that the research was approved or exempted from the need for review by the responsible review committee (institutional or national). If no formal ethics committee is available, a statement indicating that the research was conducted according to the principles of the Declaration of Helsinki should be included.

Statistical Methods

Describe statistical methods with enough detail to enable a knowledgeable reader with access to the original data to judge its appropriateness for the study and to verify the reported results. Define statistical terms, abbreviations, and most symbols. Specify the statistical software package(s) and versions used.


Present your results in logical sequence in the text, tables, and figures, giving the main or most important findings. Do not repeat all the data in the tables or figures in the text; emphasize or summarize only the most important observations. Provide data on all primary and secondary outcomes identified in the Methods Section.

Give numeric results not only as derivatives (for example, percentages) but also as the absolute numbers from which the derivatives were calculated, and specify the statistical significance attached to them, if any. Restrict tables and figures to those needed to explain the argument of the paper and to assess supporting data. Use graphs as an alternative to tables with many entries; do not duplicate data in graphs and tables. Separate reporting of data by demographic variables, such as age and sex, facilitate pooling of data for subgroups across studies and should be routine.


It is useful to begin the discussion by briefly summarizing the main findings, and explore possible mechanisms or explanations for these findings. Emphasize the new and important aspects of your study and put your findings in the context of the totality of the relevant evidence. State the limitations of your study, and explore the implications of your findings for future research and for clinical practice or policy. Do not repeat in detail data or other information given in other parts of the manuscript, such as in the introduction or the results section.


References should follow the standards summarized in the NLM’s International Committee of Medical Journal Editors (ICMJE) Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals

References must be double-spaced and numbered consecutively as they are cited. References first cited in a table or figure legend should be numbered so that they will be in sequence with references cited in the text at the point where the table or figure is first mentioned. List all authors when there are six or fewer; when there are seven or more, list the first three, followed by “et al.” The following are sample references:

Numbered references to personal communications unpublished data, or manuscripts either “in preparation” or “submitted for publication” are unacceptable. If essential, such material can be incorporated at the appropriate place in the text.

Abbreviations and Symbols

Use only standard abbreviations; use of nonstandard abbreviations can be confusing to readers. Avoid abbreviations in the title of the manuscript. The spelled-out abbreviation followed by the abbreviation in parenthesis should be used on first mention unless the abbreviation is a standard unit of measurement.

Units of Measurement

Measurements of length, height, weight, and volume should be reported in metric units (meter, kilogram, or litre) or their decimal multiples. Temperatures should be in degrees Celsius. Blood pressures should be in millimetres of mercury.


Prepare tables according to the specific journal’s requirements; to avoid errors it is best if tables can be directly imported into the journal’s publication software. Number tables consecutively in the order of their first citation in the text and supply a title for each. Titles in tables should be short but self-explanatory, containing information that allows readers to understand the table’s content without having to go back to the text. Be sure that each table is cited in the text.


Figures should be prepared in a high resolution JPEG format, preferably 300dpi and each figure number and legend is clearly described. Figures should be sent separately and not embedded in the manuscript. Size should not be more than 4x5 inches. On the top write number and title of the figure. The figure legend should be written below.


Tables should be prepared in Microsoft Table Format and sent or uploaded separately and not imbedded in the manuscript. On the top write number and title of the table. The table legend should be written below.

Review articles

Review articles are usually solicited by the editors, but we will consider unsolicited material. Please send us a presubmission Inquiry before writing a review article for the Journal. All review articles undergo the same peer-review and editorial process as original research reports. A review article should not exceed 5000 words.

State of the art articles

State of the Art papers should address issues within the framework of SHJ broad editorial mission. SHJ encourages "papers on current cardiology issues such as that covers comprehensively all relevant aspects of disease and its treatment, drugs, devices, imaging and surgery." Although State of the Art contributions are invited papers, they are subject to the same double-blind review procedure as normal submissions before final acceptance for publication. The process is intended as a developmental review to identify possible improvements that will enhance the contribution and impact of the article.

Case Reports

We want to publish cases with valuable clinical lessons. Common cases that present a diagnostic, ethical or management challenge, or that highlights aspects of mechanisms of injury, pharmacology or histopathology are deemed of particular educational value. It is essential that the learning outcomes of the articles are important and novel.

The case report should include a short abstract of 150 words, Background information, case history and discussion. It should contain no more than three high resolution figures or panels and 10 references. Authorship should be limited to maximum of three authors.

Cardiology images

If photographs of patients are used, either they should not be identifiable or the photographs should be accompanied by written permission to use them.

All text should be in one double-spaced electronic document. Please include a title for your submission. The title should contain no more than eight words. No more than three authors may be listed. Please provide the name, highest academic degree, address, e-mail address and telephone number of each author. The legend should contain no more than 150 words. You may either upload your figures separately or include figures in the text file. We prefer the former. For figures please send high-resolution files.
Please include appropriate labelling and arrows identifying structures. Each original should include an arrow indicating the top of the image. Occasionally, images have more than one panel. Please label them Panel A, Panel B, etc. 
The legend to the image should succinctly present relevant clinical information, including a short description of the patient's history, relevant physical and laboratory findings, clinical course, response to treatment (if any), and condition at last follow-up. All labelled structures in the image should be described and explained in the legend. Send images separately or in the text document.  

Clinical Quiz

This quiz tests the clinical knowledge of member cardiologist in the broad field of medicine/cardiology. Material may be ECG, Echo image, Chest Xray, CT, MRI or laboratory material. It is meant to provide diagnostic challenge to fellows and young cardiologist.
