EDITORIAL

It includes an expert opinion on a specific topic, referring to journal content or a topic that, due to its importance and topicality, requires its presentation in this format.

Maximum length 2,000 words (bibliography not included) and 5 references. By editor's invitation.

Maximum suggested length of 3,000 words (bibliography not included), 6 figures and/or tables and 40 references.

To promote transparency and quality of research, it is suggested that authors adhere to relevant international guidelines depending on the type of study:

– Clinical trials: CONSORT (http://www.consort-statement.org/). Furthermore, all trials must be registered in one of the international databases, and the corresponding registration number must always be indicated.

– Observational studies: STROBE (www.strobe-statement.org). 

– Articles on diagnostic tests: STARD (www.equator-network.org/reporting-guidelines/stard/). 

– For other types of studies, consult the guides on the EQUATOR initiative (http://www.equator-network.org/).

- Letters of an informative nature or that discuss and/or complement results of original articles published in one of the last two issues of the journal.

 

PROTOCOLS

Research protocols should describe planned or ongoing studies. Manuscripts where data collection has already been completed, or trials that require ethical committee approval without having obtained it beforehand, will not be accepted.

Protocols close to the completion of data collection will be evaluated on a case-by-case basis, and the final decision on whether to consider the protocol for publication will rest with the Editor.

Submitted protocols should offer an opportunity for researchers and funding institutions to stay informed about progress in their field, providing visibility to less visible projects. Sharing a study's full protocol offers greater transparency than standard clinical trial registries, allowing editors, reviewers, and readers to better understand any changes that may occur during the study's conduct.

Registration on official platforms is mandatory for clinical trials. Authors are encouraged to register their studies on platforms such as www.clinicaltrials.gov or on national platforms recognized by the regulatory authorities in their country. For systematic reviews, registration on platforms like Prospero is suggested.

Researchers must follow the guidelines established by SPIRIT (Standard Protocol Items for Randomized Trials) in the case of clinical trials. It is mandatory for researchers to use the SPIRIT recommendations and include a completed SPIRIT checklist when submitting their protocol.
Additionally, the use of the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) guideline is recommended. This new reporting standard includes 17 essential elements for protocols of systematic reviews and meta-analyses. Authors of systematic reviews are strongly encouraged to use this checklist when drafting and evaluating their protocols and to submit the completed checklist along with their protocol.

Structure

1. Title: Should be clear, precise, and reflect the main objective of the research. Please indicate the type of study.

2. Abstract: The abstract should be brief (200-250 words), in both Spanish and English, with a maximum of 6 keywords in each language. The structure should include: Introduction, Methods and Analysis, Discussion.

3. Main Text: The body should be developed according to the study design. In the case of clinical trials, a detailed description of sample selection, interventions, sample size, required participants, safety measures, and an analysis plan should be included. For systematic reviews or meta-analyses, the search strategy, inclusion and exclusion criteria, and methods for quality assessment and synthesis of studies should be detailed. Any ethical considerations or limitations should also be addressed in this section.

4. References: As outlined in the "Instructions for Authors" section.

 

MANUSCRIPT PRESENTATION 

Submitted articles must be accompanied by a letter, signed by all the authors of the work, stating that it has not been previously published, nor has it been sent simultaneously to another journal, that there are no conflicts of interest and if accepted, the authors transfer the copyright to Revista Peruana de Cardiología.

EDITORIAL PROCESS

The editorial process consists of 6 stages:

1. Reception of the manuscript (indeterminate, depending on whether the author meets the requirements): its objective is to verify that the manuscript complies with the specifications of these instructions for authors and that the submitted documentation is complete.

2. Initial editorial review (maximum 5 business days): its objective is to corroborate the relevance, timeliness, originality, and scientific contribution of the manuscript, as well as the methodological and statistical soundness of the study. At this time, it will be submitted to an electronic plagiarism detection system. Derived from this, a rejected opinion may be obtained, or it will be sent for review by peer researchers.

3. Review by peer researchers (maximum 30 business days): the opinion of at least two experts in the area in question will be obtained, who will evaluate the technical and methodological aspects of the investigation.

4. Editorial review (maximum 7 business days): its objective is to take a decision based on the opinion of peer reviewers. The opinion can be rejected, minor/major changes or accepted. In the case of minor/major changes, it will be submitted again for evaluation by the initial peer reviewers.

5. Final edition (6 weeks): its objective is the technical and linguistic edition (and/or translation), layout of galleys, DOI assignment, and correction by the author.

6. Advanced publication: All manuscripts will be published ahead of print on the journal's website as soon as they complete the editing process, until they are incorporated into a final issue of the journal.

 

PRINT PROOFS (PDF) OF ACCEPTED ARTICLES 

The corresponding author will receive proofs of the article for revision and correction of terminology errors, or any other updates related to facts/figures.
