The “Hellenic Journal of Atherosclerosis” is a peer-reviewed academic journal which publishes all sources papers concerned with research and investigation on atherosclerosis, its complications, and related diseases, including: Lipoprotein metabolism, arterial and vascular biology and disease, thrombosis, inflammation, disorders of lipid transport diabetes and hypertension as related to atherosclerosis, and cardiovascular risk factors. The editors are also interested in clinical papers dealing with case studies of specific or general interest, new or unusual lipid syndromes, and the genetic basis and familial incidence of atherosclerosis and related diseases. High quality reports of controlled clinical trials of drugs or diets will be considered provided the paper deals with the mechanism of action of the drug or diet.


The “Hellenic Journal of Atherosclerosis” is the official scientific journal of the Hellenic Atherosclerosis Society. Its main objective is the continuous education of scientists of various disciplines including Medical doctors, Biologists, Biochemists, Dieticians, etc. in various topics related to the pathogenesis, diagnosis and treatment of atherosclerosis.

Assembling a paper

HELLENIC JOURNAL OF ATHEROSCLEROSIS has agreed to conform to the Uniform Requirements for Manuscripts submitted to Biomedical Journals (Vancouver System) and its guidelines for authors are in accordance to the above requirements. Papers must be typed doublespace of the usual dimensions (ISO A4 210×297 mm), with margins of at least 3.5 cm. A separate page must be used for the title, the abstract and keywords, the main text, the acknowledgements, the references, the tables, the figures and the figure legends.

Title page: Concise and informative. Titles are often used in information-retrieval systems. Avoid abbreviations and formulae where possible. It contains (a) the title of the article, which must be brief (up to 12 words), (b) running title up to 50 characters, (c) name and position of the authors(s), (d) institutional affi liation of each author, (e) name, address, telephone number, fax number of the author responsible for correspondence.

Author names and affiliations: Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors’ affiliation addresses (where the actual 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. Ensure that phone numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address. Contact details must be kept up to date by the corresponding author.

Abstract and key words: A concise and factual abstract is required in English and in Greek. It must include the title, the names of the authors and the institutional affi liation of each author. It 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. Abstracts are limited to 250 words with the exception of clinical points of view and case reports whose length is limited to 150 words. The abstracts of the reviews must be descriptive, mentioning all chapters contained and the main conclusions. Abstracts of the original papers, should be structured into four paragraphs, under the following captions: Aim, Material or Patients and Methods, Results, Conclusions. It is important that the quality of the English abstract should be excellent, because it is a major criterion for the acceptance of the journal in the international lists of Biomedical journals

Immediately after the abstract, provide 3-10 keywords, using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, ‘and’, ‘of’). chosen from the MeSH terms of Index Medicus.

Text: Original papers usually contain the following chapters: Introduction, Material or Patients and Methods, Results, Discussion. The introduction contains the background and the necessary references and cites the objective of the study. The study protocol must be thoroughly described in the methodology section. Details such as the mode of patient or material selection, as well as the methodology applied must be fully disclosed in order that the research may be reproduced by future investigators. In the case of research related to human beings it must be stated that the research was performed according to the principles of the Declaration of Helsinki (1975). The pharmaceutical substances used must be mentioned  by their generic names. In the same chapter the data evaluated must be described and the chapter should be completed by an analysis of the statistical criteria used. In the next chapter the results should be presented fully but briefly. Results shown in tables should not be repeated in the text. In the Discussion, the perspectives opened up by the results of the study as well as the final conclusions are discussed. The results must not be repeated in this section. A comparison with the results of other similar studies may be done. The results may also be related to the objectives of the study but it is advisable to avoid arbitrary conclusions, not emerging from the results themselves. Acknowledgements. They are addressed only to persons who have contributed substantially.

References: They are numbered in the order in which they are first cited in the text. (e.g. Infl ammation is an independent risk factor for atherosclerosis. 1). If author names are cited in the text, first author’s surname is followed by et al. If there are only two authors, place an “and” between the two surnames. All references cited in the text -and those only- must be shown in the reference section. (e.g. 1. Libby P, Ridker PM, Maseri A. Infl ammation and atherosclerosis. Circulation 2002, 105:1135-1143).

The number of references must be limited to those absolutely necessary. Reviews must have no more than 100 references, current issues and editorials up to 10 articles or monographs considered by the author to be necessary for complete information on the subject, and letters to the Editor up to 5 references. The reference section is organized numerically based on the consecutive numbers and order of references in the text. Cite the surnames and initials of all authors up to 3 (if more, add et al after the third), the title of the article, the abbreviation of journal title, the year, volume, first and last page of the publication; e.g. You CH, Lee KY, Chey WY et al. The role of oxidative stress in atherosclerosis. Circulation 1980, 79:311–314. In case that no author name is given, cite Anonymous; e.g. Anonymous. Coffee drinking and atherosclerosis (Editorial). Br Med J 1981, 283:628-629. References of papers published in supplements, must also note the number of supplement in parenthesis after the volume, e.g. Eur Heart Journal 1996, 54(Suppl 1):26-27.

The abbreviations of journal titles must be compatible to Index Medicus. No full stops are placed after author acronyms and journal abbreviations. For books or monographs, list the surnames and initials of the authors, the title, and the number of edition, the editor, and the town of edition, the year and the pages cited. For chapter in a book, the reference must be written as follows: Papathanasiou IB. Pleiotropic actions of statins. In: Hypolipidemic drugs in atherosclerosis. BETA, Athens, 1983:67-113. If the reference consists of chapter in a book written by another author, it must be written as follows: Κuhn L, Swartz MN. Toll-like receptors. In: Lee WA (Ed) or (Eds) Infl ammation and Atherosclerosis. Saunders, Philadelphia, 1987:457-472. Unpublished material as well as personal communications should not be used as references, whereas articles accepted for publication but not yet published may be included. In this last case after the journal title abbreviation there should be an indication “to be published”. Citation of Greek references is mandatory. Greek literature can be sought at the Data Base of the Greek Medical Literature (IATROTEK),

Chapter numbering in reviews and current issues. All chapters must be numbered with Arabic numbers 1, 2, 3 etc. Subchapters should have the number of the initial chapter, point and the number of the subchapter, e.g. 1.1., 1.2. or 1.1.1., 1.2.1. etc.

Tables: They are typed double-space, in a separate page. They are numbered by the order they appear in the text, with Arabic numbers. They should have a brief, comprehensive explanation so that the reader need not turn to the text. Each column must have a brief explanatory heading. Explanations of the abbreviations should be made at the bottom of the table.

Figures:  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): PDF or JPEG.

Images: It is extremely important that a high enough file resolution is used. All separate images that you import into a figure file must be at the correct resolution before they are placed. Note, however, that the higher the resolution, the larger the file and the longer the upload time. Publication quality will not be improved by using a resolution higher than the minimum. Keep to a minimum of 300 dpi Vector drawings, embed all used fonts.

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.

Whilst it is accepted that authors sometimes need to manipulate images for clarity, manipulation for purposes of deception or fraud will be seen as scientific ethical abuse and will be dealt with accordingly. No specific feature within an image may be enhanced, obscured, moved, removed, or introduced. Adjustments of brightness, contrast, or color balance are acceptable if and as long as they do not obscure or eliminate any information present in the original.

Figure legends: On initial submission, each legend should be placed in the text file and be incorporated into the image file beneath the figure to assist review. Legends should provide enough information so that the figure is understandable without frequent reference to the text. However, detailed experimental methods must be described in the Materials and Methods section, not in a figure legend. A method that is unique to one of several experiments may be reported in a legend only if the discussion is very brief (one or two sentences). Define all symbols used in the figure and define all abbreviations that are not used in the text.

Terms and units of measurement: The authors must use the universally accepted terms and the SI units of measurement. For the choice of terms and names (of substances, entities, organizations, diseases etc.) please consult the MeSH of Index Medicus.

Acknowledgements: Collate acknowledgements in a separate section at the end of the article before the references. List here those individuals who provided assistance during the research.

Math formulae: Present simple formulae in the line of normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of “e” are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

Footnotes: Footnotes should be used sparingly. Number them consecutively throughout the article, using superscript Arabic numbers. Many word processors build footnotes into the text, and this feature may be used. Should this not be the case, indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article. Do not include footnotes in the reference list.

Reprints: Photocopy reproduction of published papers is not allowed.

Primary publication

Manuscripts submitted to the journal must represent reports of original research, and the original data must be available for review by the editor if necessary. By submitting a manuscript to the journal, the authors guarantee that they have the authority to publish the work and that the manuscript, or one with substantially the same content, was not published previously, is not being considered or published elsewhere, and was not rejected on scientific grounds by another journal. It is incumbent upon the author to  acknowledge any prior publication, including his/her own articles, of the data contained in a manuscript submitted to  the journal. A copy of the relevant work should be submitted with the paper as supplemental material not for publication. Whether the material constitutes the substance of a paper and therefore renders the manuscript unacceptable for publication is an editorial decision. In the event that the authors’ previously published figures and/or data are included in a submitted manuscript, it is incumbent upon the corresponding author to (i) identify the duplicated material and acknowledge the source on the submission form, (ii) obtain permission from the original publisher (i.e., copyright owner), (iii) acknowledge the duplication in the figure legend, and (iv) cite the original article.

Review Process

To expedite the review process, authors should recommend at least two editors and also at least three reviewers (i) who are either Editorial Board members or otherwise qualified scientists who are not members of their institution(s), (ii) who have not recently been  associated  with  their  laboratory(ies), and (iii) who could not otherwise be considered to pose a conflict of interest regarding the submitted manuscript. Please provide their contact information where indicated on the submission form. Impersonation of another individual during the review process is considered serious misconduct.

When a manuscript is submitted to the journal, it is given a control number (e.g., and assigned to one of the editors. It is the responsibility of the corresponding author to inform the coauthors of the manuscript’s status throughout the submission, review, and publication processes. The corresponding author is informed for receipt of the manuscript and the number of registration. The manuscripts are first checked whether they have been written and submitted according to the instructions of the Journal (instructions to authors). Manuscripts which do not meet the requirements of correct submission are returned to the corresponding author with instructions for due corrections. The manuscript is double – blind checked by special consultant reviewers of the Journal. The revised manuscript must be accompanied by a signed letter by the corresponding author, in which he /she declares that all corrections have been made. The final decision of the manuscript acceptance lies on the Editorial Board that decides for approval, or return of manuscript for supplementary information, decision for re-approval or to reject the manuscript. As soon as the paper is accepted and has been allotted final publication, a proof is dispatched to the authors for final checking.
