About the Rome IV Criteria for Functional Chest Pain
Cardiac assessment comes first and is not one of the criteria — Rome IV assumes it has already been done. What the criteria then require is retrosternal chest pain or discomfort occurring at least once a week over three months with onset at least six months ago, the absence of heartburn and dysphagia, no evidence that reflux disease or eosinophilic oesophagitis is responsible, and no major oesophageal motor disorder. The absence of other oesophageal symptoms is what makes this diagnosis distinct: chest pain accompanied by heartburn belongs to functional heartburn or reflux hypersensitivity instead.
Formula
Functional chest pain = ALL of:
retrosternal chest pain or discomfort, cardiac causes already excluded
AND absence of oesophageal symptoms such as heartburn and dysphagia
AND no evidence that reflux disease or eosinophilic oesophagitis is the cause
AND no major oesophageal motor disorder
AND criteria fulfilled for the last 3 months, onset >= 6 months ago,
at least once a week- Cardiac causes excluded
- A precondition rather than a Rome IV criterion. The criteria assume cardiac assessment is already complete.
- Absence of heartburn and dysphagia
- Prominent oesophageal symptoms move the patient to functional heartburn, reflux hypersensitivity or functional dysphagia instead.
- At least once a week
- Lower than the twice-weekly threshold used for functional heartburn and reflux hypersensitivity.
- Cardiac assessment is assumed complete before the criteria are applied; Rome IV does not list it as a criterion.
- Heartburn or dysphagia as prominent symptoms move the patient to a different functional oesophageal disorder.
Interpreting the result
Meeting the criteria should change the consultation more than it changes the investigation, because by this point the investigation is complete. The single most useful thing is to give the explanation positively and concretely: the oesophagus and the heart share nerve pathways, which is why oesophageal pain is felt as cardiac pain and why it is frightening; the pain is real; and there is a treatment. Neuromodulators — tricyclics, SSRIs or trazodone at low doses — are first-line, with hypnotherapy and cognitive behavioural therapy both having trial evidence. Where criteria are not met, read which one failed. A failure on the symptom criteria usually means the patient belongs in a different Rome IV oesophageal disorder rather than having no functional diagnosis. A failure on the exclusions usually means an investigation has not been done, and the one most often missing is high-resolution manometry — distal oesophageal spasm and jackhammer oesophagus both present as chest pain and are treatable in ways functional chest pain is not.
| Score | Band | What it means | Action |
|---|---|---|---|
| All criteria met | Functional chest pain | Oesophageal hypersensitivity with central pain amplification, after cardiac, reflux, mucosal and motor causes have been excluded | Give the explanation positively; start a neuromodulator and consider hypnotherapy or CBT |
| Any criterion unmet | Criteria not met | Either the symptom profile fits a different oesophageal disorder, or an investigation is outstanding | If heartburn or dysphagia coexists, assess for those disorders instead. If manometry has not been done, do it |
What the Functional Chest Pain needs (5 inputs)
- Timing and frequency
- Criteria fulfilled for the last three months, onset at least six months before diagnosis, occurring at least once a week. Weekly here, not the twice-weekly threshold applied to functional heartburn and reflux hypersensitivity.
- Retrosternal chest pain or discomfort, cardiac causes excluded
- Cardiac exclusion is a precondition rather than a Rome IV criterion, which is a subtlety worth understanding — the criteria do not tell you how thoroughly to investigate the heart, they assume you already have.
- Absence of heartburn and dysphagia
- The discriminating feature. Rome IV's oesophageal disorders are mutually exclusive by symptom profile, and coexisting heartburn moves the patient to functional heartburn or reflux hypersensitivity; coexisting dysphagia moves them to functional dysphagia.
- No evidence that reflux disease or eosinophilic oesophagitis is the cause
- Requires endoscopy with oesophageal biopsies and, where reflux remains a question, monitoring. Eosinophilic oesophagitis can present with chest pain and a normal-looking oesophagus.
- No major oesophageal motor disorder
- Achalasia, EGJ outflow obstruction, distal oesophageal spasm, jackhammer oesophagus or absent contractility. Spasm and jackhammer oesophagus in particular present with chest pain and are the ones this criterion is really guarding against.
What it returns
- Criteria met or not met
- All five requirements including the timing rule must be satisfied simultaneously.
- Which criteria remain outstanding
- Named explicitly, so it is clear whether the diagnosis fails on a symptom or on an investigation not yet done.
How it is calculated
The criteria are structured as one symptom requirement and three exclusions, which reflects how the diagnosis is actually reached: chest pain is a symptom with a large and dangerous differential, and the work is in clearing it rather than in characterising the pain. The mechanistic account Rome IV offers is oesophageal hypersensitivity combined with altered central pain processing — the oesophagus reports normal events as painful, and the central nervous system amplifies rather than damps that signal. That model is what justifies neuromodulators as first-line treatment, since they act on the second half of it. The requirement for absent heartburn and dysphagia is not physiological but taxonomic: the committee designed the five oesophageal disorders to be mutually exclusive so that a patient lands in exactly one, and symptom profile is the sorting mechanism.
Facts & figures
| Accompanying symptom | Rome IV disorder to assess |
|---|---|
| None | Functional chest pain |
| Heartburn, with normal acid exposure and negative symptom association | Functional heartburn |
| Heartburn or chest pain, normal acid exposure, positive symptom association | Reflux hypersensitivity |
| Dysphagia | Functional dysphagia |
| Painless lump in the throat between meals | Globus |
The five oesophageal disorders were written to be mutually exclusive. A patient should meet one set of criteria, and meeting two indicates a scoring error rather than complex disease.
| Category | Investigation |
|---|---|
| Cardiac | Complete cardiac assessment — a precondition, not a Rome IV criterion |
| Mucosal and structural | Endoscopy with oesophageal biopsies (biopsies exclude eosinophilic oesophagitis) |
| Reflux | pH or pH-impedance monitoring where reflux remains a question |
| Motor | High-resolution manometry — distal oesophageal spasm and jackhammer oesophagus present as chest pain |
Musculoskeletal chest wall pain and panic disorder are not named in the criteria but coexist frequently and should be assessed alongside rather than after.
Evidence
Derivation — Rome Foundation, oesophageal disorders committee
2016Consensus criteria produced by the Rome IV oesophageal disorders committee, published in Gastroenterology in 2016 as a revision of Rome III.
Consensus-derived; no sensitivity or specificity against an objective reference standard, since none exists for a symptom-defined disorder. The criteria's function is to make the diagnosis reproducible and to enforce a complete exclusion work-up.
Motor disorder framework — Chicago Classification v4.0
2021International consensus defining oesophageal motility disorders on high-resolution manometry.
Defines the major motor disorders that must be absent, including distal oesophageal spasm and hypercontractile (jackhammer) oesophagus — the two that most often present as chest pain and are specifically treatable.
Reflux exclusion framework — Lyon Consensus 2.0
2024International consensus on conclusive evidence for and against gastro-oesophageal reflux disease.
Sets the thresholds on reflux monitoring that determine whether reflux disease can be excluded as the cause, which the Rome IV criterion depends on.
How it compares
Functional Chest Pain vs Distal oesophageal spasm and jackhammer oesophagus
These are the treatable motor causes of the same symptom, and excluding them is a Rome IV criterion — which means manometry is mandatory rather than optional.
Both are defined on high-resolution manometry by the Chicago Classification, and both present with chest pain that is clinically indistinguishable from functional chest pain at the bedside. They matter because they have specific treatments — smooth muscle relaxants, and in selected cases peroral endoscopic myotomy for spastic disorders — that functional chest pain does not respond to. A patient labelled functional without manometry may have a mechanical explanation that was never looked for. This is the single strongest argument for completing the physiology testing before applying the Rome IV label.
Functional Chest Pain vs Reflux hypersensitivity
Reflux hypersensitivity can present as chest pain too — the separator is whether reflux monitoring shows the symptoms tracking reflux events.
Functional chest pain requires no evidence that reflux is responsible; reflux hypersensitivity requires positive evidence that reflux events trigger the symptoms, with normal acid exposure. A patient with non-cardiac chest pain and a positive symptom-reflux association therefore has reflux hypersensitivity. The practical difference is that reflux-directed treatment is worth trying in reflux hypersensitivity and is not in functional chest pain. Both are then treated with neuromodulators, so the consequence of the distinction is one additional therapeutic option rather than a completely different pathway.
Functional Chest Pain vs Panic disorder
Not alternatives but frequent companions — each amplifies the other, and treating only one usually disappoints.
Panic disorder produces chest pain, breathlessness and a conviction of cardiac catastrophe, and it is common in patients presenting repeatedly with non-cardiac chest pain. Functional chest pain, in turn, generates the frightening recurrent symptom that panic attaches to. Rome IV does not list psychiatric comorbidity as an exclusion, and it should not be treated as one — a patient can have both. Practically, screening for panic is worth doing in every patient meeting these criteria, because the treatments overlap substantially and addressing only the oesophageal side leaves a large part of the problem untouched.
Pearls & pitfalls
- Cardiac exclusion is a precondition, not a criterion. Rome IV does not tell you how far to investigate the heart, and a functional label applied over an incomplete cardiac assessment is unsafe rather than merely premature.
- Coexisting heartburn takes the patient out of this diagnosis. Chest pain with heartburn is assessed as functional heartburn or reflux hypersensitivity — the disorders are mutually exclusive.
- High-resolution manometry is the investigation most often skipped, and it is the one that matters most here. Distal oesophageal spasm and jackhammer oesophagus present as chest pain and have specific treatments.
- Biopsies at endoscopy are required. Eosinophilic oesophagitis can cause chest pain with a normal-looking oesophagus.
- Once a week is the frequency threshold, not twice — this is a lower bar than functional heartburn and reflux hypersensitivity.
- Panic disorder and functional chest pain coexist frequently and each worsens the other. Screening for it is not in the criteria but belongs in the assessment.
- Musculoskeletal chest wall pain is common, reproducible on palpation, and easily missed because nobody examines the chest wall of a patient whose troponin is being checked.
- Explain the neuromodulator as acting on nerve sensitivity rather than on mood, or the patient will not take it.
- A normal angiogram is not the end of the pathway. It is the point at which the oesophageal assessment starts.
Critical actions
- Confirm the cardiac assessment is genuinely complete before applying this label — this is the one step where getting the order wrong is dangerous.
- Examine the chest wall for reproducible musculoskeletal pain, which is common and frequently overlooked.
- Perform endoscopy with oesophageal biopsies to exclude mucosal disease and eosinophilic oesophagitis.
- Obtain high-resolution manometry — spasm and jackhammer oesophagus are the treatable motor causes of this presentation.
- Arrange reflux monitoring where reflux remains a plausible contributor after endoscopy.
- Screen for panic disorder and anxiety, which coexist frequently and respond to overlapping treatment.
- Give the diagnosis positively, naming the mechanism — shared nerve pathways between oesophagus and heart, with amplified central pain processing.
- Start a neuromodulator at low dose and consider hypnotherapy or cognitive behavioural therapy, both of which have trial evidence here.
Why this score exists
The committee's decision to leave cardiac exclusion outside the criteria is deliberate and often misread. Rome IV is a set of gastroenterological definitions, and specifying how thoroughly to investigate the heart would take it beyond its scope and date badly as cardiac testing evolves. The consequence is that the criteria are silent on the most important safety step in the whole assessment, which places the responsibility on the clinician rather than the checklist. The other design choice worth noting is the insistence on absent heartburn and dysphagia. It is not that chest pain and heartburn cannot coexist physiologically — they plainly can — but that the committee wanted five non-overlapping categories so that trial populations would be clean and a patient would not accumulate three functional labels for one problem.

Limitations
- Silent on cardiac exclusion, which is the most consequential step in the assessment and is left entirely to the clinician's judgement.
- Requires high-resolution manometry and often reflux monitoring, so the diagnosis cannot be made properly without access to oesophageal physiology testing.
- The requirement for absent heartburn and dysphagia is taxonomic rather than physiological, and forces a patient with mixed symptoms into a single category that may not describe them well.
- A consensus definition whose accuracy cannot be measured, since it is defined by what a full cardiac and oesophageal work-up fails to find.
- Does not address the psychological comorbidity — panic disorder in particular — that accompanies this presentation frequently and drives much of its burden.
- Says nothing about severity, and a patient meeting criteria may be mildly troubled or severely disabled.
- Musculoskeletal chest wall pain, a common and easily identified mimic, is not named in the exclusions.
- Developed largely in Western populations, where the reporting and interpretation of chest pain differ from other settings.
If you are the patient
Functional chest pain means recurring pain behind the breastbone that is coming from the oesophagus — the food pipe — rather than from the heart. Your heart will have been checked thoroughly first, because that always comes first, and the tests on your oesophagus will also have come back normal. That combination can feel like being told nothing is wrong, but it is not: there is a specific explanation. The oesophagus and the heart share nerve pathways, which is why pain from the gullet is felt in the same place as heart pain and feels just as alarming. In this condition those nerves are over-reporting normal sensations, and the brain is amplifying rather than filtering the signal. Because the pain is real and the mechanism is nerve sensitivity, the treatments that work are ones that act on nerves — usually low doses of medicines also used as antidepressants, prescribed here for pain rather than mood. Hypnotherapy focused on the gullet and cognitive behavioural therapy also have good evidence. Two things worth raising with your doctor: whether your chest wall has been examined, since muscle and joint pain there is common and easily missed; and whether anxiety or panic is part of the picture, because it very often is, it makes the pain worse, and it responds to treatment too.
Frequently asked questions
What are the Rome IV criteria for functional chest pain?#
Retrosternal chest pain or discomfort with cardiac causes excluded; absence of heartburn and dysphagia; no evidence that reflux disease or eosinophilic oesophagitis is responsible; and no major oesophageal motor disorder. All must be fulfilled for the last three months with onset at least six months earlier, occurring at least once a week.
Is excluding a cardiac cause part of the Rome IV criteria?#
It is a precondition rather than a listed criterion. Rome IV assumes cardiac assessment has already been completed and does not specify how it should be done — that would take a gastroenterological consensus outside its scope and would date quickly. The practical implication is that responsibility for the cardiac work-up sits with the clinician, not the checklist.
Can you have functional chest pain and heartburn together?#
Not within these criteria. The absence of heartburn and dysphagia is an explicit requirement, because Rome IV's five oesophageal disorders were written to be mutually exclusive. Chest pain accompanied by heartburn should be assessed for functional heartburn or reflux hypersensitivity instead, depending on what reflux monitoring shows.
Why is manometry needed for functional chest pain?#
Because distal oesophageal spasm and jackhammer oesophagus present with chest pain that is indistinguishable at the bedside, are defined only on high-resolution manometry, and have specific treatments that functional chest pain does not respond to. Excluding a major motor disorder is a Rome IV criterion, so the diagnosis cannot properly be made without manometry.
What treats functional chest pain?#
Neuromodulators are first-line — tricyclic antidepressants, SSRIs or trazodone at low doses chosen for their effect on pain processing rather than mood. Oesophageal-directed hypnotherapy and cognitive behavioural therapy both have trial evidence. Explaining the mechanism clearly is itself part of the treatment, because it is what reduces repeat presentation.
How often does the pain need to occur?#
At least once a week, over the last three months, with onset at least six months before diagnosis. That is a lower frequency bar than Rome IV applies to functional heartburn and reflux hypersensitivity, both of which require twice weekly.
Is functional chest pain the same as non-cardiac chest pain?#
Not quite. Non-cardiac chest pain is a broad descriptive term for chest pain without a cardiac cause, and it includes reflux disease, motor disorders, musculoskeletal pain and panic. Functional chest pain is a specific Rome IV diagnosis reached after those have been excluded — it is a subset of non-cardiac chest pain, not a synonym for it.
Does anxiety cause functional chest pain?#
They coexist far more often than chance and each worsens the other, but Rome IV does not treat psychiatric comorbidity as an exclusion and a patient can have both. Panic disorder in particular is common in this group. Screening for it is worthwhile because the treatments overlap substantially, and addressing only the oesophageal side tends to leave a large part of the problem untreated.
