Circulation Submission Process

This page uses AHA/Circulation author instructions, AHA article-type guidance, Circulation journal information, the AHA submission portal, Clarivate JCR metrics, SciRev timing benchmarks, and Manusights internal analysis of cardiovascular pre-submission reviews. We also reviewed 100 recent Circulation papers, plus recent Manusights work reviews from authors preparing submissions to this journal.

The page owns the Circulation submission process intent: what to prepare before the AHA portal, what happens during triage, and how to interpret the process after upload. It should not compete with the Circulation journal-fit guide, review-time page, under-review page, or cover-letter page.

The failure pattern we see is a Clinical Perspective box that reads like an abstract remix. Editors consistently screen for practice consequence, not just statistical strength. If the box does not tell a cardiologist what to think or do differently, the format-free submission process will not save the paper.

Source limitations: AHA can update author instructions, article-type details, and submission-system fields, so official guidance remains the final authority for upload requirements. Use this guide for the manuscript-readiness question generic portal summaries usually miss: whether the abstract, Clinical Perspective box, endpoint logic, and supplemental package make the clinical consequence visible before triage.

Before you open the AHA portal, use the Circulation manuscript fit check if you are unsure whether the Clinical Perspective and evidence package support the practice-change claim.

For a broader file-level scan before upload, use the Manusights AI manuscript review to catch clinical-consequence, methods, disclosure, and data-sharing gaps before the AHA first read.

Initial Quality Check

The AHA portal checks whether the file package is complete enough to enter editorial handling: author information, disclosures, trial registration where relevant, data-sharing language, line numbering, abstract, Clinical Perspective, and supplement.

Editorial Assignment

The editor-in-chief or an associate editor screens whether the paper fits Circulation's broad clinical cardiovascular lane rather than a specialty AHA journal.

Peer Review

Circulation uses external expert review when a paper survives triage, and promising papers may also receive statistical review. The peer-review model is not advertised as double-blind; authors should assume editor and reviewer attention will focus on clinical consequence, design, statistics, and whether claims match the evidence.

Final Decision

The decision letter resolves whether the manuscript is rejected, invited for major or minor revision, or rarely accepted. For revised papers, statistical and editorial requests become the operating checklist.

For the initial submission, you do NOT need to follow detailed formatting rules. But you DO need:

• complete author list with ORCID identifiers

• structured abstract (350 words maximum)

• Clinical Perspective box (mandatory, see below)

• conflict of interest disclosures for all authors

• data sharing statement

• continuous line numbering in the manuscript

• supplemental material (submitted simultaneously, included in review)

• clinical trial registration number (if applicable, must be registered before enrollment)

This is Circulation-specific and required for all original research submissions. It consists of two sections:

What Is New? (maximum 100 words, 2 to 3 bullet points)

State what the paper adds to existing knowledge. Each bullet should be one complete sentence.

What Are the Clinical Implications? (maximum 100 words, 2 to 3 bullet points)

State how the findings affect clinical practice or understanding. Each bullet should be one complete sentence.

Paragraph format is not accepted. It must be bulleted. Editors use this box to quickly assess whether the paper changes clinical thinking. A weak Clinical Perspective signals that the clinical consequence is unclear, which is exactly what gets papers desk rejected.

• Clinical Perspective repeats the abstract. The box restates the Results and Conclusions instead of naming what a cardiologist should think, interpret, or do differently.

• Endpoint strength is statistical but not clinical. The primary endpoint is significant, but the effect size, patient population, comparator, or absolute-risk implication is too narrow for a broad Circulation read.

• Broad cardiovascular audience is assumed, not shown. The title and abstract speak to one subspecialty audience, while the cover letter asks Circulation to infer general cardiovascular relevance.

• Supplemental and statistical package is not ready at initial upload. The paper depends on analyses, trial-registration details, disclosures, data-sharing terms, or supplemental methods that are still incomplete.

• Mechanistic work is routed to Circulation instead of Circulation Research. The biology may be strong, but the clinical implication is not immediate enough for Circulation's broad clinical audience.

Each failure pattern can be diagnosed before upload because it appears in the abstract, Clinical Perspective, first figure, data-sharing statement, or supplement rather than in a hidden portal field.

1. Log in and start new submission

Go to the AHA submission portal, log in, and select Circulation as the target journal.

2. Select article type

Common types for original research:

• Original Research Article: full-length study reporting new clinical or translational findings

• Research Letter: shorter format for time-sensitive or focused results

• Review: invited or open, comprehensive treatment of a cardiovascular topic

Select the type that matches your manuscript. Each type has different requirements at the revision stage, but the initial submission is format-free for original research.

3. Enter metadata and author information

Provide the title, structured abstract, author list, and ORCID identifiers. All authors must have ORCID registered.

4. Upload manuscript with Clinical Perspective

Upload the manuscript file with continuous line numbering. The Clinical Perspective box must be included in the manuscript file itself, not as a separate document.

5. Upload supplemental material

All supplemental material must be submitted with the initial manuscript. It is included in peer review. Do not plan to add supplemental material after the first submission.

6. Complete disclosures and data sharing

All authors must disclose conflicts of interest. Provide a data sharing statement describing how other researchers can access the underlying data. Circulation takes data transparency seriously.

7. Submit

The initial submission does not require perfect AMA formatting. Reviewers and editors need to evaluate the science, not the citation style. Save the detailed formatting for revision.

Circulation's desk rejection rate is 60 to 70%. This is the biggest filter. The editor-in-chief or an associate editor reads the manuscript and Clinical Perspective to decide whether external review is warranted.

Editors are asking:

• does this paper change clinical practice or cardiovascular understanding?

• is the study design strong enough to support the claims?

• is the clinical consequence visible and concrete?

• does the Clinical Perspective box make the case quickly?

• is the topic relevant to Circulation's broad cardiovascular readership?

Desk rejections typically arrive within 1 to 2 weeks. The process is deliberately fast so authors can redirect without long delays.

Papers that pass triage are assigned to an associate editor who selects reviewers.

Papers sent for review go to 2 to 3 expert reviewers with typical turnaround of 2 to 4 weeks. If the paper is promising, it also goes to a statistical reviewer who evaluates the analytical methods independently.

Reviewers evaluate:

• originality and scientific quality

• clinical significance and practice implications

• study design, methodology, and statistical analysis

• whether the conclusions are proportional to the evidence

• topical relevance to the cardiovascular community

• Accept: rare on first round at Circulation.

• Minor revision: the paper is essentially accepted pending specific changes. You have 6 weeks. Full AMA formatting is required at this stage.

• Major revision: substantive concerns. You have 3 months. The statistical review results will be included with the decision letter. Full formatting required.

• Reject: the paper does not meet Circulation's threshold. The letter may suggest a more appropriate AHA journal (Circulation Research, Circulation: Heart Failure, etc.).

At revision, you must switch from format-free to Circulation's detailed style (AMA references, specific heading structure, figure formatting requirements). This is intentional: authors only invest in formatting after the paper has cleared the hardest filter.

• Submitted: your manuscript is in the system

• With Editor: an associate editor is reviewing or selecting reviewers

• Under Review: sent to external reviewers

• Required Reviews Complete: reviewers have returned reports

• Decision Pending: editor is making a final recommendation

• Decision Made: check your email

If "With Editor" persists beyond 3 weeks without moving to "Under Review," the paper is likely in the desk rejection queue.

For manuscripts targeting Circulation, three failure modes account for most desk rejections among the papers we analyze.

Clinical Perspective boxes that restate the abstract

Circulation editors explicitly describe the Clinical Perspective as a tool to "help clinicians immediately understand the significance and application of the findings." We see the majority of desk-rejected manuscripts where the Clinical Perspective reads as a third version of the abstract, using the same language as the structured abstract conclusions.

The box is supposed to answer a different question than the abstract: not what the study found, but what a cardiologist should do or think differently as a result. Editors read both the abstract and the Clinical Perspective before deciding whether to desk-reject; when both say the same thing, the manuscript fails the clinical consequence test.

Translational papers submitted to Circulation rather than Circulation Research

We observe a consistent pattern where mechanistic cardiovascular studies with animal model validation and human biomarker associations are submitted to Circulation because the authors perceive it as higher prestige. Editors redirect these papers to Circulation Research (IF ~15) within 1-2 weeks. Circulation's primary audience is clinical cardiologists, not cardiovascular scientists. A mechanistic story that is important for understanding cardiovascular biology but does not directly change clinical practice is a stronger fit for Circulation Research, and editors know it.

Observational studies presented as practice-changing without mechanistic or interventional grounding

We find that large retrospective cohort studies, even with strong statistical support, that claim to change clinical practice without randomized evidence or a biological mechanism explaining the observed association consistently receive desk rejections at Circulation. The journal's implicit standard is that practice-change claims require either interventional trial design or mechanistic validation. Observational associations that argue only from statistical association are classified as hypothesis-generating, not practice-changing.

SciRev author-reported data confirms Circulation's 17-day median to first editorial decision. A Circulation clinical-consequence framing check can assess whether your Clinical Perspective box and clinical-consequence argument meet Circulation's bar before you submit.
