AUTHOR INQUIRIES



Indian Heart Journal (IHJ) is the official journal of Cardiological Society of India (CSI) and accepts articles for publication from across the globe. IHJ is a bi-monthly peer-reviewed journal and aims to publish work of the highest quality from all sub-specialties of cardiology- clinical and non-clinical including cardiovascular medicine and surgery. The journal invites original research articles, research briefs, perspective, case reports, case vignette, cardiovascular images, cardiovascular graphics, research letters, correspondence, reader forum, and interesting photographs, for publication. The aim of the publication is to promote research in India and serve as platform for dissemination of scientific information in cardiology particularly from South Asia

Categories of Articles

Articles can be submitted as Original Research Articles, Research Briefs, Review Articles, Perspective, Case Reports, Case Vignettes, Cardiovascular Images, Cardiovascular Graphics, Research Letters and Correspondence, Reader Forum and Interesting Photographs.

Original Research Articles: Original, in-depth research article that represents new and significant contributions to medical science. These articles should report research relevant to clinical cardiology including randomized clinical trials, Cardiac intervention studies, studies of screening and diagnostic tests, cohort studies, systematic reviews, cost-effectiveness analyses, case control studies and cross-sectional studies. Before reporting a clinical trial we strongly urge the authors to register their clinical trials involving human subjects in CTRI (Clinical Trials Registry of India), available at http://www.ctri.in, hosted by the Indian Council of Medical Research. Each manuscript should be accompanied by a structured abstract of not more than 250 words using the following headings: Objective, Methods (discussing design, setting, participants/patients, interventions (if any) and end-points), Results, and Conclusions. Four to five key words to facilitate indexing should be provided in alphabetical order below the abstract. The text should be arranged in sections on INTRODUCTION, METHODS, RESULTS and DISCUSSION. One line key messages could also be provided at the end of the manuscript in a box under headings: ‘What is Already Known?’ and ‘What this Study Adds?’ Number of tables and figures should be limited to a maximum of 4 and 2, respectively. Extra tables and figures, subject to clearance by editorial review process, can be allowed on payment or may be made available only at the journal website. The typical text length for such contributions is up to 3000 words (including title page, abstract, tables, figures, acknowledgments and key messages). Number of references should be limited to 40.

Research Briefs: Brief accounts of descriptive, observational studies, epidemiological assessments, and surveys are published as Research Briefs. A series of cases can also be considered as Research Briefs. Abstract should be unstructured, limited to 100 words, and highlight the aims, methods and main results. Provide 2-3 key words. The text should contain not more than 1000 words, two illustrations/ tables and up to 15 references, preferably recent publications. The text should be arranged in order of INTRODUCTION, METHODS, RESULTS and DISCUSSION. One line key messages could also be provided at the end of the study. The number of authors should be limited to 5.

Review Articles: These are comprehensive review articles on topics of current interest in Cardiology. The review should not exceed 5000 words (including tables, and figures). Authors submitting review articles should include an abstract of around 200 words describing the need and purpose of review, methods used for locating, selecting, extracting and synthesizing data, and main conclusions. The number of references should be limited to 50. Following types of articles can be submitted under this category:
• Newer drugs
• New technologies
• Review of a current concept

Please note that generally review articles are by invitation only. But unsolicited review articles will be considered for publication on merit basis. The authors may consult the Honorary Editor before submitting such articles, as similar reviews may already be in submission. Normally, a review article on a subject already published in Indian Heart Journal in last 3 years is not considered.

Perspective: Articles published under this heading intend to cover challenging and controversial topics of current interest in clinical cardiology and the intersection between medicine and society. The issues covered could be of national, regional (South East Asia) or global interest. Though the articles are usually solicited, we welcome submissions and proposals from researchers and opinion makers, provided they have sufficient credible experience and recognition on the subject for giving opinions. Some manuscripts submitted as ‘Review Articles’ may also be considered for publication under this section at the discretion of editors. The following guidelines need to be followed: The number of authors should be limited to maximum of 3. The topic should be specific and related to the practice of cardiology in general. Word limit: 2000 words and may include one figure and one table. Unstructured abstract of up to 150 words is acceptable. The views should be supported by appropriate evidence and references. Number of references should be limited to a maximum of 10.

Case Reports: Only case reports of exceptional quality will be published in the case report format. Single case reports will not be accepted, unless some new or unusual aspect regarding etio-pathogenesis, diagnosis or management is brought out that adds to the existing body of knowledge. The text should not exceed 1000 words and is arranged as introduction, case report and discussion. Include a brief abstract of about 50 words. Number of tables/figures should be limited to 2. Include up to 5 most recent references. Photographs could be high-resolution color or black and white. For details, see below under Figures and Illustrations. A maximum of 3 authors are permitted from a single department. Case reports involving more than one department can have a maximum of 4 authors. The patient’s written consent, or that of the next of kin, to publication must be obtained. The authors would be asked to submit a signed consent form before publication for all case reports and images.

Case Vignette: Reflections of clinical cases focussing on some interesting point may also be considered. The case should be 200 words, fit in 1 page having 1-2 illustrations and upto 2 references.

Cardiovascular Images: Only clinical photographs with/without accompanying skiagrams or pathological images, echocardiography images, angiographic images etc. are considered for publication. Image should clearly identify the condition and have the classical characteristics of the clinical condition. Clinical photographs of condition which are very common, extremely rare, where diagnosis is obvious, or where diagnosis is not at all possible on images alone would not be considered. Photographs should be of high quality, usually 127 × 173 mm (5 × 7 in) but no larger than 203 × 254 mm (8 × 10 in). A short text of about 150 words depicting the condition is needed. Figures should be submitted separately from the text file. The submitted images should be of high resolution (>300 dpi). The following file types are acceptable: TIFF, EPS, and JPEG. The number of authors should not exceed 2. The authors should ensure that images of similar nature have not been published earlier. Authors must obtain signed informed consent from the patient.

Cardiovascular Graphics: This will include any ECG / EP, oximetry or hemodynamic trace which is interesting and makes a teaching point. The graphics need to be limited to 4 and should be followed by a brief commentary to describe the illustration. The commentary should focus on the graphic/s rather than on the clinical presentation/management/outcome. The accompanying commentary should be limited to 150 words.

Research Letters: Under this heading, short communication pertaining to research would be included. Research Letters reporting original research should not exceed 500 words of text and upto 5 references. They may have no more than 4 authors; other persons who have contributed to the study may be indicated in an acknowledgment section, with their permission. An abstract of up to 50 words reporting the key findings should also be included. Letters must not duplicate other material published, submitted or planned to be submitted for publication. In general, the matter of the letter could be unstructured but should follow the general sequence of introduction, methods, results and discussion and all other standard guidelines of a manuscript.

Correspondence: Letters commenting upon recent articles in Indian Heart Journal are welcome. Such letters should be received within 16 weeks of the article’s publication. At the Editorial board’s discretion, the letter may be sent to the authors for reply and the letter alone or letter and reply together may be published after appropriate review. Letters should not have more than 300 words; contain no more than 1 Figure/Table and upto 5 most recent references. The text need not be divided into sections. The number of authors should not exceed 3, including the authors’ reply in response to a letter commenting upon an article published in Indian Heart Journal. In the latter case, inclusion of only one of the authors (of the article in question) is permissible, besides the corresponding author names of additional persons who have helped in data acquisition can be mentioned in the acknowledgment section.

Reader Forum: Readers may send questions of common interest. Editorial board will try to solicit answers from experts; and publish them, if found suitable.

Interesting Photograph: These are unsolicited photographs, not necessarily related to the mandate of the Journal, published as space fillers. There are no restrictions on subject matter, but photographs of familiar people are generally not published. A digital picture of 300 dpi or higher resolution in TIFF, EPS, and JPEG format needs to be submitted.

Covering letter

The covering letter should explain any deviation from the standard IMRAD (Introduction, Methods, Results, and Discussion) format and should outline the importance and uniqueness of the work. It should include the signed declaration from all authors on:
1. The category of manuscript (original research, review articles, case reports etc.
2. Statement that the material has not been previously published or submitted elsewhere for publication (This restriction does not apply to abstracts published in connection with scientific meetings.) 3. Transfer of copyright to the Indian Heart Journal upon the acceptance of the manuscript for publication
4. All authors have reviewed the article and agree with its contents
5. Information of any conflicts of interest (of any) of the authors
6. Sources of research support, if any, including funding, equipment, and drugs
The covering letter should also include the mailing address, telephone and fax numbers, and e-mail address of the corresponding author.

Manuscript preparation

The manuscripts should comply with the following guidelines. Title page (Page 1) should contain:
• Title
• Brief abstract of the article (For Original articles, review articles and case reports)
• Name(s) of author(s), their academic qualifications and current affiliations
• Name, mailing and e-mail addresses of the corresponding author
• Key words
• Information relating to any conflicts of interest of any of the authors and sources of research support, if any, including funding, equipment, and drugs should be included in the manuscript before references. Also include acknowledgement of financial support, if any.

The title represents the subject matter of the manuscript. A subtitle can be added if necessary. The title should be brief and comprehensive. Keywords should be the listed terms in the medical subject's headings (MeSH) of the Index Medicus, to help in easy indexing.

The manuscript should be well organized and written in simple and correct English under appropriate headings. The abbreviations and acronyms should be spelled out when they occur first time.

The Introduction should address the subject of the paper. The Methods section should describe in adequate detail the laboratory or study methods followed and state the statistical procedures employed in the research. This section should also identify the ethical guidelines followed by the investigators with regard to the population, patient samples or animal specimens used. A statement should be made that their study conforms to widely accepted ethical principles guiding human research (such as the Declaration of Helsinki) AND also that their study has been approved by a local ethics committee.

The Results section should be concise and include pertinent findings and necessary tables and figures. The Discussion should contain conclusions based on the major findings of the study, a review of the relevant literature, clinical application of the conclusions and future research implications. Following the Discussion, Acknowledgements of important contributors and funding agencies may be given. The editorial office must receive written, signed consent from each contributor recognized in the Acknowledgements because the statement can imply endorsement of data and conclusions.

Article structure

Subdivision - numbered sections
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. Each heading should appear on its own separate line.

Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Material and methods
Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described.

Theory/calculation
A Theory section should extend, not repeat, the background to the article already dealt with in the Introduction and lay the foundation for further work. In contrast, a Calculation section represents a practical development from a theoretical basis.

Results
Results should be clear and concise.

Discussion
This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

Conclusions
The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

Appendices
If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.

Essential title page information

Title. Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
Author names and affiliations. Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.
Present/permanent address. If an author has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address') may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

Abstract

A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

Keywords

Immediately after the abstract, provide a maximum of 6 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

Abbreviations

Define abbreviations that are not standard in this field in a footnote to be placed on the first page of the article. Such abbreviations that are unavoidable in the abstract must be defined at their first mention there, as well as in the footnote. Ensure consistency of abbreviations throughout the article.

Acknowledgements

Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).

Units

Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.

Units of measurement should be given in conventional units. All bio-clinical measurements should be given in conventional units, with Systeme International d'unites (SI) units given in parenthesis. Generic rather than trade names of drugs should be used.

Artwork

Figures and graphics
1. For graphics, a digital picture of 300 dpi or higher resolution in TIFF, EPS, and JPEG format should be submitted.
2. Figures should be in Arabic numerals, consecutively according to the order in which they have been first cited in the text, if there is more than 1 figure. Each figure should be cited in the text.
3. Each figure/illustration should be provided with a suitable legend that includes enough information to permit its interpretation without reference to the text.
4. All photomicrographs should indicate the magnification of the prints.
5. When symbols, arrows, numbers or letters are used to identify parts of the illustrations, each one should be explained clearly in the legend.

Electronic artwork
General points
• Make sure you use uniform lettering and sizing of your original artwork.

• Submit each illustration as a separate file.
A detailed guide on electronic artwork is available on our website:
http://www.elsevier.com/artworkinstructions.
You are urged to visit this site; some excerpts from the detailed information are given here.
Formats
If your electronic artwork is created in a Microsoft Office application (Word, PowerPoint, Excel) then please supply 'as is' in the native document format.
Regardless of the application used other than Microsoft Office, when your electronic artwork is finalized, please 'Save as' or convert the images to one of the following formats (note the resolution requirements for line drawings, halftones, and line/halftone combinations given below):
EPS (or PDF): Vector drawings, embed all used fonts.
TIFF (or JPEG): Color or grayscale photographs (halftones), keep to a minimum of 300 dpi.
TIFF (or JPEG): Bitmapped (pure black & white pixels) line drawings, keep to a minimum of 1000 dpi.
TIFF (or JPEG): Combinations bitmapped line/half-tone (color or grayscale), keep to a minimum of 500 dpi.
Please do not:
• Supply files that are optimized for screen use (e.g., GIF, BMP, PICT, WPG); these typically have a low number of pixels and limited set of colors;
• Supply files that are too low in resolution;
• Submit graphics that are disproportionately large for the content.

Color artwork
Please make sure that artwork files are in an acceptable format (TIFF (or JPEG), EPS (or PDF) or MS Office files) and with the correct resolution. If, together with your accepted article, you submit usable color figures then Elsevier will ensure, at no additional charge, that these figures will appear in color online (e.g., ScienceDirect and other sites) in addition to color reproduction in print. For further information on the preparation of electronic artwork, please see http://www.elsevier.com/artworkinstructions.

Figure captions
Ensure that each illustration has a caption. Supply captions separately, not attached to the figure. A caption should comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Tables

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. Number tables consecutively in accordance with their appearance in the text and place any table notes below the table body. Be sparing in the use of tables and ensure that the data presented in them do not duplicate results described elsewhere in the article. Please avoid using vertical rules.

1. Number tables in the order of their find it citation in the text. Each table should be cited in the text in Arabic numerals.
2. Titles should be brief and a short or abbreviated heading for each column should be given. Explanatory matter should be placed in footnotes and not in the heading.
3. Abbreviations in each table should be explained in footnotes.
4. The data presented in a table should not be repeated in the text or figure.

References

The authors are responsible for the accuracy and completeness of the references and their citations in the text.
1. References should be numbered consecutively in the order in which they are first mentioned in the text.
2. References in text, tables and legends should be identified by superscript Arabic numerals at the end of the sentence outside any punctuation. If several different studies or papers are cited within one sentence, the number should be placed where it will accurately identify the correct study.
3. The names of authors in the text should concur with the reference list.
4. References cited only in tables or in legends to figures should be numbered in accordance with a sequence established by the first identification in the text of the particular table or illustration.
5. Abstracts as references may be used; "unpublished observations" and "personal communications" may not be used as references, although references to written, not oral, communications may be inserted (in parentheses) in the text.
6. Papers accepted but not yet published may be included as references by adding "In press" after the journal name. Information from manuscripts submitted but not yet accepted should be cited in the text as "unpublished observations" (in parentheses).
7. In general: • All authors/editors should be listed unless the number exceeds three, when you should give three followed by "et al." • Full page number for first page and as many digits as are changed for final page need to be mentioned. For more details and examples of correct forms of references, please refer to ICMJE guidelines sheet at http://www.nlm.nih.gov/bsd/uniform_requirements.html.

The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication. The assigned DOI never changes. Therefore, it is an ideal medium for citing a document, particularly 'Articles in press' because they have not yet received their full bibliographic information. Example of a correctly given DOI (in URL format; here an article in the journal Physics Letters B):
http://dx.doi.org/10.1016/j.physletb.2010.09.059
When you use a DOI to create links to documents on the web, the DOIs are guaranteed never to change.

Online proof correction

Corresponding authors will receive an e-mail with a link to our online proofing system, allowing annotation and correction of proofs online. The environment is similar to MS Word: in addition to editing text, you can also comment on figures/tables and answer questions from the Copy Editor. Web-based proofing provides a faster and less error-prone process by allowing you to directly type your corrections, eliminating the potential introduction of errors.
If preferred, you can still choose to annotate and upload your edits on the PDF version. All instructions for proofing will be given in the e-mail we send to authors, including alternative methods to the online version and PDF.
We will do everything possible to get your article published quickly and accurately. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. It is important to ensure that all corrections are sent back to us in one communication. Please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.

Offprints

The corresponding author, at no cost, will be provided with a personalized link providing 50 days free access to the final published version of the article on ScienceDirect. This link can also be used for sharing via email and social networks. For an extra charge, paper offprints can be ordered via the offprint order form which is sent once the article is accepted for publication. Both corresponding and co-authors may order offprints at any time via Elsevier's WebShop (http://webshop.elsevier.com/myarticleservices/offprints). Authors requiring printed copies of multiple articles may use Elsevier WebShop's 'Create Your Own Book' service to collate multiple articles within a single cover (http://webshop.elsevier.com/myarticleservices/offprints/myarticlesservices/booklets).
