The manuscript should be written in English (US / UK spell) in a clear, concise and precise style. Files in Word's .docx or .doc format format are accepted; we advise creating math equations using Word 2007’s equation editor. Please use the template file when preparing the manuscript. If you have any questions (regarding manuscript preparation, submission...) or maybe you encounter difficulties during the use of the website, please don't hesitate to ask for help: [email protected]

The Original research articles must be divided into the following sections:

Title page

The title of the article should be precise and brief. Authors should avoid the use of abbreviations. Article title should be capitalized and presented without word hyphenation, in semi-bold font (Times New Roman, 14 pt). Last names and initials of authors are italicized. Title page should include paper title, author(s) full name and affiliation, corresponding author(s) names complete affiliation/address, along with phone, fax and email.

Abstract

An abstract of maximum 250 words should be typed on a separate page in a form of a single paragraph and should be written in an informative style.

The abstract form is defined by the manuscript type: a structured abstract has 5 sections (Aim, Material and Methods, Results, Conclusion, Keywords), while an unstructured abstract contains a brief work description and Keywords.

The content of the paper should be characterized by at least 3 and not more that 10 keywords in English (use MeSH when is appropriate).

Text

All manuscript pages should be single-sided, font size 12, 1.5 interval, all margins of 2.0 cm, and left alignment. The text should be carefully edited and proofread by the author(s). All the pages should be numbered consecutively, beginning with title page.

Original research articles should be structured into the following sections: Introduction, Material and Method, Results, Discussion and Conclusions.

1. Introduction: Provide a context or background for the study (i.e., the nature of the problem and its significance). State the specific purpose or research objective of, or hypothesis tested by, the study or observation at the end of this section.

2. Material and Method: The Methods section should include only information that was available at the time the plan or protocol for the study was written; all information obtained during the conduct of the study belongs in the Results section. All data must be available to any reader of Cardiometry. Any restrictions on the availability of data, codes, or materials must be disclosed to the editors upon submission. If study methods include X-ray exposure, detailed description and exposure doses should be presented.

Data sets (including microarray data, genes, protein or DNA sequences, mutants, diseases, atomic coordinates or electron microscopy maps for macromolecular structures) must be deposited in an approved database, and an accession number or a specific access address must be included in parentheses after the entity on first use in the manuscript. Use the recommended name by consulting the appropriate genetic nomenclature database, e.g., HUGO for human genes. The Recommended International Non-Proprietary Name (rINN) of drugs should be provided.

We encourage compliance with MIBBI (Minimum Information for Biological and Biomedical Investigations) and MIAMI guidelines. Suggested databases include, but are not limited to:

• ArrayExpress
• BioModels Database
• ClinicalTrials.gov
• Database of Interacting Proteins
• DNA Data Bank of Japan [DDBJ]
• DRYAD
• EMBL Nucleotide Sequence Database
• GenBank
• UniProtKB/Swiss-Prot
• Worldwide Protein Data Bank

Providing accession numbers allows linking to and from established databases and integrates your article with a broader collection of scientific information.

For data sets with no appropriate approved repository and further information about accessibility of data and materials please contact [email protected].

Clinical trial reports should comply with the Clinical Trial Registration Statement from the International Committee of Medical Journal Editors, the Consolidated Standards of Reporting Trials (CONSORT).

Studies on Diagnostic Tests should comply with “The STARD Statement for Reporting Studies of Diagnostic Accuracy: Explanation and Elaboration,” Ann Intern Med. 2003;138:40-44. Technical information. Identify the methods, apparatus (give the manufacturer’s name and address in parentheses), and procedures in sufficient detail to allow other researchers to reproduce the study. Briefly describe for methods that have been published but are not well known (provide also the references). Describe in details new or substantially modified methods, give reasons for using them, and evaluate their limitations.

Statistics. Describe statistical methods with enough detail to enable a knowledgeable reader with access to the original data to verify the reported results. When possible, quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). Define statistical terms, abbreviations, and most symbols. Avoid non-technical uses of technical terms in statistics, such as “random” (which implies a randomizing device), “normal,” “significant,” “correlations,” and “sample.” Specify the computer software used. All published manuscripts are reviewed by a statistical expert and should comply with the Uniform Requirements for Manuscripts Submitted to Biomedical Journals.

3. Results: Present your results in logical sequence in the text, tables, and illustrations, giving the main or most important findings first. Do not repeat in the text all the data in the tables or illustrations; emphasize or summarize only important observations. 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 methods used to analyze them. Restrict tables and figures to those needed to explain the argument of the paper and to assess its support. Use graphs as an alternative to tables with many entries; do not duplicate data in graphs and tables.

4. Discussion and Conclusions: Emphasize the new and important aspects of the study and the conclusions that follow from them. Do not repeat in detail data or other material given in the Materials and Methods or the Results section. State new hypotheses when warranted, but clearly label them as such. Link the conclusions with the goals of the study but avoid unqualified statements and conclusions not adequately supported by the data.

Abbreviations

Please keep abbreviations to a minimum. Abbreviations should be standard and clear to the readers. Authors must avoid using abbreviations which could have more than one meaning. List all non-standard abbreviations in alphabetical order, along with their expanded form. Define them as well upon first use in the text. The list of abbreviations and their definitions should follow the standards for research publications.

The use of standardized nomenclature in all fields of science is an essential step toward the integration and linking of scientific information. Please use the SI units or provide the SI value in parentheses after each value.

Figures

This section provides general information for authors creating figures and preparing artwork for submission to Cardiometry.

Figures should be embedded in the main manuscript file.

Figures titles and legends should be provided in the main manuscript. The aim of the figure legend should be to describe the key messages of the illustration, but the illustration should also be discussed in the text. The legend should be succinct, while still explaining all symbols and abbreviations. Avoid lengthy descriptions of methods. If the reference to the figure is a part of a sentence, it is spelled-out as 'Figure 1'; the reference in brackets is abbreviated as (Fig. 1). Please note that it is the responsibility of the author(s) to obtain permission from the copyright holder to reproduce figures (or tables) that have previously been published elsewhere. In order for all figures to be open access, authors must have permission from the rights holder if they wish to include images that have been published elsewhere in non-open access journals. Permission should be indicated in the figure legend, and the original source included in the reference list. All figures will be published under a Creative Commons Attribution License, which allows them to be freely used, distributed, and built upon as long as proper attribution is given. Please do not submit any figures that have been previously copyrighted unless you have express written permission from the copyright holder to publish under the CCAL license.

TIFF, JPEG and PNG formats are preferred. Figures should be at 300 dpi, maximum width is 180 mm. Individual illustration (figure) files should not exceed 3 MB.

Tables

Tables should be embedded together with its number, title, and explanatory information (footnotes and abbreviations) in the manuscript.

If the reference to the table is a part of a sentence, it is spelled-out as 'Table 1'; the reference in brackets is abbreviated as (Tab. 1).

All tables should identify the measurement units and specify the data presentation (e.g., M±m; M±SD; median; mode; percentiles, etc.). All numbers, totals, and percentages should be double-checked and correspond to the respective part of the text. If necessary, authors should place explanatory matter in footnotes. Abbreviations should be listed alphabetically in the table footnote.

Multimedia and supporting information

Multimedia files (video, audio, etc.) are posted on free hosting resources and can be downloaded from them using the relevant links provided in the manuscript. The editorial staff reserves the right to insert one of the video frames as a picture into the manuscript. To clarify these issues, please, contact us under [email protected]

References

Only published or accepted manuscripts should be included in the reference list. Personal communications, manuscripts in preparation or other unpublished data may be cited in the text in parentheses. If letters to the editor are cited, identify them with the word 'letter' in parentheses. Identify abstracts by the abbreviation 'abstr' in parentheses. Citation of unpublished work should be included in the text only as “unpublished data”. All “personal communications” citations should be supported by a letter from the relevant authors.

References are listed and numbered in the order that they appear in the text and listed in the same numerical order in the Reference section. It should be typed double-spaced on pages separate from the text.

• In the text, citations should be indicated by the reference number with use of Arabic numerals in square brackets, for example [1]. If the same reference is used again, re-use the original number.
• Abstracts may not contain citations.
• Journal name abbreviations should be found in the NCBI databases, if available, or abbreviated according to the format accepted by the journal itself on the journal website.

Authors are responsible for the accuracy and completeness of their references and for correct text citation.

All Russian sources should be transliterated, i.e. authors names and journal titles are transliterated, while article titles are translated. Transliteration could be performed using various online resources, such as http://www.translit.ru.

The references should comply with the format recommended by the American National Information Standards Organization (NISO), adapted by the National Library of Medicine for its databases (MEDLINE/PubMed). DOI and/or PMID (if available) must be indicated for all articles in References.
