JACC Submission Process

This page is about workflow after upload.

Use it when you want to understand:

• what happens once the manuscript enters the JACC system

• what editors are really screening for first

• how to interpret quiet periods, triage, and reviewer-routing slowdowns

• what usually causes a paper to lose momentum before full review

If you still need to decide whether the package is ready, that belongs on the submission-guide page.

The process usually feels cleaner when the manuscript already arrives with:

• a broad-enough cardiovascular audience case

• a practice-facing consequence that is visible early

• methods and figures stable enough for a hard first read

• complete declarations, reporting materials, and supporting files

If those pieces are soft, the workflow can feel harsher than authors expect because the system exposes weakness early.

That is why the timing promise matters. A fast first decision only helps when the paper already looks broad enough, mature enough, and strong enough for a flagship cardiology screen.

The first stage is not only testing whether the study is interesting.

It is testing whether:

• the paper belongs in JACC rather than a narrower cardiology title

• the paper belongs in the flagship rather than elsewhere in the JACC family

• the practical consequence is strong enough to justify reviewer time

• the evidence package supports the framing on the first read

• the manuscript looks stable enough for a flagship editorial path

That is why fast rejection here often means "not broad or mature enough for JACC," not "bad science."

The current JACC guide for authors makes the mechanics of triage unusually clear. At initial submission, editorial staff first check style compliance and whether the manuscript is clear and legible for reviewers and editors. The paper then goes to the Editor-in-Chief, then an Associate Editor, who decides whether it should even be sent for peer review. If two reviews are completed, the submission is then discussed in a weekly associate editor meeting before a final editorial decision is reached.

JACC also separates its standard path from an expedited one. For Original Investigations considered suitable for expedited handling, the editors commit to a decision on expedited suitability within 2 days and an initial decision within 14 days. That matters because it tells you what the journal values operationally: a paper should look complete, high-priority, and easy to position from the first read.

A practical JACC timeline is 2 to 25 days for early to reviewed first decisions, with expedited, delayed, and other edge case submissions moving outside that range when urgency, reviewer availability, statistical review, or journal-family routing changes the path.

Initial Quality Check: file, style, and package readiness

The first operational stage is an Initial Quality Check. It is where the manuscript file, declarations, reporting details, figures, and readable package structure need to look complete enough for editors and reviewers.

Editorial Assignment: flagship fit and clinical consequence

Editorial Assignment is the stage where the Editor-in-Chief and Associate Editor decide whether the paper belongs in JACC and whether the clinical consequence is broad enough for flagship cardiology readers.

Peer Review: confidential external review if triage clears

JACC's public guide describes standard external peer review and associate-editor discussion after reviewer reports. It does not position the process as transparent peer review or open peer review, so authors should treat the review path as confidential unless the journal instructs otherwise.

Final Decision: JACC decision or better JACC-family route

The Final Decision stage can mean review, revision, decline, or a clearer JACC-family route. For authors, the important preparation is to know before upload whether the paper is truly flagship JACC or more naturally suited to a specialist JACC title.

Authors should think in stages:

• the earliest period is mostly fit, breadth, and package-stability judgment

• movement into fuller editorial consideration usually means the hardest flagship screen has been cleared

• later slowdowns often reflect reviewer matching or evidentiary questions rather than journal-level fit

The practical point is that the real risk sits early. Once the paper survives that first triage read, the process becomes more about how well the evidence carries the claim.

Authors often think the submission process is about forms, declarations, and file formatting. Those steps matter, but they are not the real decision.

The real decision is whether the manuscript already looks like a credible JACC paper before the editor finishes the abstract, title, cover letter, and opening figures.

That means the process is really testing:

• fit

• breadth

• package stability

• editorial confidence

Editors punish overbroad framing very quickly at flagship cardiology journals

In Manusights reviews, the strongest JACC submissions make the clinical consequence visible in the title, abstract, and first figures without forcing the editor to infer why the readership should care.

The recurring check is component by component: whether the structured abstract states the patient-facing consequence, whether the central illustration makes the practical implication visible without a long caption, whether the first figure supports the same claim size as the title, whether the methods and reporting package can withstand fast clinical scrutiny, and whether the cover letter explains why JACC readers need the paper rather than only why the authors want JACC.

We also check whether the limitations, clinical perspectives, supplemental tables, disclosures, trial registration, and data-availability language all support the same sized claim.

Check whether your JACC clinical consequence is visible enough ->

What actually gets filtered early is mismatch, not only weakness

We regularly see strong cardiovascular manuscripts that still read more naturally as subspecialty papers. Those often struggle not because the science is poor, but because the journal-choice argument is still aspirational.

Check whether your paper belongs in JACC or a JACC-family title ->

Operational clarity matters more here than authors assume

If the abstract, figure sequence, cover letter, and disclosures do not all support the same sized claim, JACC's fast editorial path becomes harsher rather than more forgiving.

Check your JACC submission package before upload ->

The fourth recurring pattern is not a new science flaw, but an assembly flaw: the manuscript file, structured abstract, cover letter, central illustration, reporting details, disclosures, and data-availability language are all individually acceptable, yet they do not create one JACC-sized submission package. JACC editors do not need to prove the paper is weak to stop the process.

They only need to see that the clinical consequence is not broad enough, that the first figure and central illustration are doing different jobs, or that the cover letter is trying to compensate for unclear fit.

The important point is that the submission process exposes the mismatch quickly. A paper can be strong cardiovascular science and still be aimed at the wrong JACC-family lane.

Before opening the portal, the manuscript should already show:

• a clear cardiovascular problem

• a practical or translational consequence

• a figure set that makes the argument visible early

• a cover letter that explains journal fit directly

• a methods and reporting package that looks stable enough for review

If those pieces are still moving, upload day is too early.

The technical workflow is standard enough:

• upload the manuscript

• upload figures and supplements

• complete declarations and author information

• provide the cover letter and required metadata

Treat the ACC submission portal as the Manuscript Tracking System for this process: it records files, metadata, declarations, editorial movement, and author correspondence, but it does not repair a weak flagship-fit argument.

But each of those items is also part of the first editorial impression.

Before submitting to JACC, a JACC manuscript fit check identifies whether the package meets the editorial bar before you commit to the submission.

This is where many submissions rise or fall.

Editors are usually asking:

• does this paper belong in JACC rather than a narrower cardiology journal

• is the practical consequence strong enough to justify reviewer time

• does the evidence package support the claims on first read

• does the paper already look finished rather than one revision short

That is not peer review yet. It is a fast decision about fit and readiness.

• Clinical consequence buried below the methods: the study may be rigorous, but the first read does not show why JACC readers should change their view.

• Central illustration weaker than the abstract: the paper claims broad cardiology consequence, while the main visual still looks like a specialist mechanism.

• JACC-family routing mismatch: the manuscript is strong cardiovascular science, but it fits Interventions, Heart Failure, Clinical Electrophysiology, or another sibling title more naturally.

• Expedited request without expedited evidence: the cover letter asks for speed, but the urgency, patient consequence, or practice implication is not obvious from the package.

A strong package usually has:

• one clear cardiovascular question

• one obvious reason the answer matters

• one coherent figure sequence

• one cover letter that explains fit directly

• one package that looks stable enough for review now

This is why the submission process is not neutral. It reveals whether the authors already understand the venue.

The cover letter should reduce editorial uncertainty, not repeat the abstract.

It should help the editor see:

• what the paper changes

• why the change matters to JACC readers

• why the manuscript is ready now

• why another journal is not the cleaner fit

If the letter mostly signals ambition, it usually increases skepticism instead of reducing it.

If the submission clears the first triage read, the manuscript usually moves into a more detailed editorial consideration phase.

That stage is still not the same as a positive signal. It usually means:

• the fit is plausible

• the package is strong enough to justify more time

• the editor does not see an immediate reason to decline

What helps at this stage is not more novelty language. What helps is that the manuscript already looks internally aligned:

• title

• abstract

• figures

• cover letter

• discussion

When those parts are all making the same case, the process feels smoother.

Even strong cardiovascular papers can lose momentum in the process when:

• the claim sounds broader than the evidence package

• the abstract emphasizes importance more than the figures do

• the cover letter explains fit in generic terms

• the manuscript reads like a strong specialist paper aimed one tier too high

JACC is especially unforgiving of that kind of positioning mismatch because the journal has to defend reviewer time against many submissions that are already technically good.

These do not usually matter as much as fit, but they still add friction:

• inconsistent author metadata across files

• a cover letter that names the wrong journal or wrong audience

• figure files that are disorganized or hard to interpret

• declarations that make the package feel unfinished

None of these guarantees rejection on its own. But together they reinforce the feeling that the package is not yet fully disciplined.

Before you press submit, do one last short pass that focuses only on editorial confidence.

Check:

• whether the first page explains the practical consequence quickly

• whether the abstract and figures make the same sized claim

• whether the cover letter argues fit instead of aspiration

• whether the package still looks broad enough for JACC rather than a narrower cardiology venue

That final check often catches the exact mismatch that causes a fast decline.

It is also the fastest way to tell whether the paper is truly ready now or merely close, which is often the difference between review and an early stop at triage.
