Editorial Process Top

A manuscript will be reviewed for possible publication with the understanding that the manuscript is the original work of the authors; does not duplicate any other previously published work of the authors, and has been submitted  solely to Cardiology Plus and not simultaneously submitted elsewhere or under consideration or peer review, accepted for publication or published elsewhere. For publications with more than one author, the Journal expects authors to authorize one of them to correspond with the Journal on all matters related to the manuscript. Received manuscripts will be acknowledged. Initially, editors review all submitted manuscripts for suitability for formal peer-review. The journal follows single-blind peer-review process. Manuscripts that lack originality, have serious scientific or technical flaws, or are unlikely to be of interest to Cardiology Plus readers are rejected before proceeding to formal peer-review.  

Manuscripts deemed suitable for formal peer-review are sent to two or more expert reviewers. During submission, authors may has an opportunity to identify two or three qualified reviewers with experience in the subject of the submitted manuscript but are not required to do so. Reviewers should not be affiliated with the same institution(s) as the author/s. Selection of reviewers is at the sole discretion of the editor. The Journal follows a double-blind review process, wherein the reviewers and authors are unaware of each other's identity. Additionally, every manuscript is assigned to a member of the editorial team, who, based on comments from the reviewers, makes a final decision as to whether the manuscript shall be published. Reviewer comments and suggestions (acceptance/ rejection/ revisions or amendments to manuscript) are conveyed to the corresponding author. Authors may be required to provide a point-by-point response to reviewers' comments and submit a revised manuscript. This process is repeated until reviewers and editors are satisfied with the manuscript and deem it publishable in Cardiology Plus.

Manuscripts accepted for publication are copy edited for grammar, punctuation, print style, and format. Page proofs will be provided to the corresponding author. The corresponding author is expected to return corrected proofs within fourteen days of their receipt by the author. Revisions may not be incorporated in the final publication if proofs are not returned in a timely fashion. The process of manuscript submission to final decision and sending and receiving of proofs is completed online. The Journal is committed to expedient dissemination of knowledge and information. As such, immediately upon acceptance, articles are published online as 'Ahead of Print'.

Clinical Trial Registry   Top

Cardiology Plus only publishes clinical trials registered with a clinical trial registry that allows free online access to the public. Registration in the following trial registries is acceptable:;;;;; and This is applicable to clinical trials that started enrolling subjects as early as June 2008. To be considered for publication in Cardiology Plus, clinical trials that commenced subject enrollment prior to June 2008 must be registered retrospectively with a clinical trial registry that allows unhindered and free-of-charge online access to the public.

Authorship Criteria Top

Authorship credit should be based on substantial contributions to each of the following three components:

  1. Concept and design of study or acquisition of data or analysis and interpretation of data;
  2. Drafting of manuscript or revising of manuscript critically for important intellectual content; and
  3. Final approval of manuscript to be published.

Participation solely in acquisition of funding or collection of data does not justify authorship. General supervision of the research group from which the manuscript originates is not sufficient for authorship. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the manuscript content. The order in which authors are listed should be based on the relative contribution of each author towards the study and writing of the manuscript. Once submitted, the order in which authors are listed cannot be changed without written consent of all authors. The Journal prescribes a maximum number of authors for manuscripts depending upon the type of manuscript, its scope, and the number of institutions involved (vide infra). Authors should provide a justification, if the number of authors exceeds the requisite limits.

Contribution Details Top

Each author shall describe his or her contributions with respect to the manuscript. Such description shall be divided into the following categories, as applicable: concept, design, definition of intellectual content, literature search, clinical studies, experimental studies, data acquisition, data analysis, statistical analysis, manuscript preparation, manuscript editing and manuscript review. One or more authors shall assume responsibility for the integrity of the work as a whole from inception to published article and should be designated as corresponding author/s. 

Conflicts of Interest/ Competing Interests Top

Each author must disclose any and all perceived or actual conflicts of interest that he or she (or his or her institution) may have related to publication of the manuscript. In particular if any of the authors have a financial interest related to  products or processes that are mentioned in the manuscript, these conflicts of interest must be disclosed. If any of the authors have a financial interest in products or processes that are competitive with those mentioned in the manuscript, such financial interest must be disclosed.

Manuscripts received from Editorial Board members will be screened by the Editor in Chief and sent to external peer reviewers. The editorial board members who are authors will be excluded from publication decisions and need to acknowledge in the “Conflicts of interest” statement that they are Editorial Board members of the journal.

Submission of Manuscripts Top

All manuscripts must be submitted online through the website Cardiology Plus Submission Portal. An author submitting a manuscript to the Journal for the first time, then you must register. Registration is free but mandatory. Registered authors can track submitted manuscripts by logging in.

The Journal does not charge for submission and processing of manuscripts.

If an author experiences any issues with manuscript submission, that author should contact the editorial office by sending an email to [email protected] or call +86-13913504664.

Submitted manuscripts that do not comply with these 'Instructions to Authors' will be returned to the authors for correction as to form, before they undergo editorial/peer-review. Generally, a manuscript should be submitted in the following format:

Types of Manuscripts Top

Original Articles:

These include reports of randomized controlled trials or interventional studies, studies of screening and diagnostic tests, outcome studies, cost effectiveness analyses, case-control series, and surveys. Manuscripts of original articles comprising up to 3000 words (excluding Abstract, References and Tables) should be divided into the following sections: Abstract, Keywords, Introduction, Materials and Methods, Results, Discussion, References, Table and Figure Legends. Each section shall include a heading identifying the particular section.

Introduction: State the purpose and summarize the rationale for the study or observation.

Materials and Methods: Include and describe the following:

Ethics: When reporting studies on human beings, indicate whether the procedures followed were in accordance with (1) the ethical standards of the responsible committee on human experimentation (institutional or regional) and (2) the Helsinki Declaration of 1975, as revised in 2000 (available at

For studies involving human participants, authors should describe measures taken to obtain (1) approval by (regional/ national/ institutional or independent Ethics Committee or Review Board; and (2) informed consent from adult research participants; and (3) informed consent from parents or guardians, as well as the assent of children, that are study subjects. The age at which an individual may provide assent, or informed consent, may vary per regional and/ or national guidelines. Ensure confidentiality of subjects by refraining from mentioning participants' names, initials or hospital numbers, especially in illustrative material. When reporting experiments on animals, indicate that local and national regulations were followed for the care and use of laboratory animals was followed. The attestation by the authors that they have obtained local regulatory review and have adhered to local and national regulations regarding ethical treatment of human and animal subjects must be included in all research articles under the 'Materials and Methods' section.

If requested, authors must supply evidence of approval by a local Ethics Committee (for both human as well as animal studies). Animal experimental procedures shall be as humane as possible, and the details of anesthetics and analgesics used shall be clearly stated. The ethical standards of experiments must be in accordance with the guidelines provided by the CPCSEA and World Medical Association Declaration of Helsinki on Ethical Principles for Medical Research Involving Humans for studies involving experimental animals and human beings, respectively). The Journal will not consider any paper that does not meet the requisite standards of ethics.

Study design: 

Selection and Description of Participants: Clearly describe method used to select observational or experimental participants (patients or laboratory animals, including controls), including inclusion and exclusion criteria and a description of the source population.  Technical Information: Identify the methods, apparatus (provide manufacturer's name and address in parentheses), and procedures in sufficient detail to enable others to reproduce the results. Give references to established methods, including statistical methods (see below); provide references and brief descriptions for methods that have been published but are not well known; describe new or substantially modified methods, give reasons for using them, and evaluate their limitations. Identify with specificity all drugs and chemicals used, including generic name(s), dose(s), and route(s) of administration.

Reports of randomized clinical trials should present information on all major study elements, including the protocol, assignment of interventions (methods of randomization, concealment of allocation to treatment groups), and the method of masking (blinding), based on the CONSORT Statement (

Reporting Guidelines for Specific Study Designs:

Observational studies including cohort, case-control, and cross-sectional studies


Randomized controlled trials


Quality improvement projects


Systematic reviews and meta-analyses


Studies of diagnostic accuracy


Case Reports


Clinical Practice Guidelines


The reporting guidelines for other type of studies can be found at

Statistics: Whenever possible quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). Authors should report data that is lost to observation (such as, dropouts from a clinical trial). When data are summarized in the Results section, specify the statistical methods used to analyze them. Avoid non-technical uses of technical terms in statistics, such as 'random' (which implies a randomizing device), 'normal', 'significant', 'correlations', and 'sample'. Define statistical terms, abbreviations, and most symbols. Specify the computer software used. Use upper case italics (P 0.048). For all P values include the exact value and not less than 0.05 or 0.001. Mean differences in continuous variables, proportions in categorical variables and relative risks including odds ratios and hazard ratios should be accompanied by their confidence intervals.

Results: Present results in a 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. Extra- or supplementary materials and technical detail can be placed in an appendix where it will be accessible but will not interrupt the flow of the text; alternatively, it can be published only in the electronic version of the journal.

When data are summarized in the Results 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 methods used to analyze them. Restrict tables and figures to those needed to sufficiently support and/or illustrate the conclusions of the manuscript. Use graphs as an alternative to tables with many entries; do not duplicate data in graphs and tables. Where scientifically appropriate, analyses of the data by variables such as age and sex should be included.

Discussion: Include summary of key findings (primary outcome measures, secondary outcome measures, results as they relate to a prior hypothesis); strengths and limitations of the study (study question, study design, data collection, analysis and interpretation); interpretation and implications in the context of the totality of evidence (is there a systematic review to refer to, if not, could one be reasonably done here and now, what this study adds to the available evidence, effects on patient care and health policy, possible mechanisms); Controversies raised by the study; and future research directions (for this particular research collaboration, underlying mechanisms, clinical research).

Do not repeat in detail data or other material given in the Introduction or the Results section. In particular, authors should avoid making statements on economic benefits and costs unless the manuscript includes economic data and analyses. Avoid claiming priority and alluding to work that has not been completed. New hypotheses may be stated if needed; however, they should be clearly labeled as such. About 30 references may be included.

Review Articles:

Only individuals who have performed substantial work on the subject matter of the review or are considered experts in the field of review should author a Review Article. A short summary of the work done by the author(s) in the field of review should accompany the manuscript.

The prescribed word count is up to 3000 words excluding tables, references and abstract. The manuscript may have about 90 references. The manuscript should have an unstructured Abstract (250 words) representing an accurate summary of the article. The section titles depend upon the topic reviewed. Authors submitting review articles should include a section describing the methods used for locating, selecting, extracting, and synthesizing data. These methods should also be summarized in the Abstract.

The Journal expects authors to give post-publication updates on the subject of review. The update should be brief, covering the advances in the field after publication of the article and should be sent as a letter to the editor, as and when a major development occurs in the field.

Case Reports:

Case reports present clinical observations customarily collected in healthcare delivery settings. They have proved helpful in the identification of adverse and beneficial effects, the recognition of new diseases, unusual forms of common diseases, and the presentation of rare diseases.

Case reports can comprise up to 1000 words (excluding Abstract and References) and should have the following headings: Abstract (unstructured), Keywords, Introduction, Timeline,Case Presentation(Patient Information, Clinical Findings,Diagnostic Assessment, Therapeutic Intervention, Follow-up and Outcome),Discussion, Conclusion, Acknowledgement, Consent, Conflict of Interest, Reference, Tables and Legends in that order.

We recommend a timeline in the form of a table or figure that gives the specific dates and times of important components of the case. This might include family and past medical history, genetic information, current symptoms, diagnostic test results, interventions, and events that occurred during follow-up. The timeline should show how the key events of the case unfolded.  Please refer to the following example.



Nine months before presentation

Bone marrow cytology, immunological panel, and a platelet antibody test suggested immune thrombocytopenia, but treatment with glucocorticoid and gamma globulin was not effective.

Two weeks before presentation

Recurrent chest pain and shortness of breath started.

First week of hospital stay

Diagnosis of acute myocardial infarction with heart failure (48% LVEF) and very low platelet count of 10×10^9/L. Clopidogrel (75mg/day), statin, nitrate, β-blocker, spironolactone, furosemide and milrinone were given, and platelet count was monitored.

Second weeks of hospital stay

Chest pain gradually subsided but left heart failure persisted. Coronary angiography showed 90% occlusion of the proximal left anterior descending artery with slow blood flow. A zotarolimus-eluting stent was implanted. ST segment normalized and heart failure improved.

3-month follow-up

The patient had no shortness of breath or bleeding. Platelet count was 9×10^9/L. LVEF was 63%.

8-month follow-up

Patient developed pneumonia and subsequent heart failure. Platelet count was 2×10^9/L, and the patient received platelet transfusion. Clopidogrel was discontinued. Ginkgo Leaf Tablet was initiated.

12-month follow-up

No shortness of breath. No thrombotic event or bleeding. Platelet count at 6×10^9/L.

16-month follow-up

Platelet count at 1×10^9/L; hemoglobin at 65 g/L. No apparent bleeding. The patient received platelet and red blood cell transfusion. Ginkgo Leaf Tablet was discontinued.

We recommend authors to apply the CAse REport (CARE) guidelines checklist in preparing the manuscript of case reports, which is structured to correspond with key components of a case report and capture useful clinical information (including ‘meaningful use’ information mandated by some insurance plans).

The CARE guidelines are shown in the following Table1.
