Chest Pain: When to Seek Help
and What Tests to Expect

Chest pain is one of the most alarming symptoms a person can experience — and one of the most misunderstood. Most cases are not cardiac emergencies. But some are. Dr George Xynopoulos explains how to tell the difference, when to call 999, and which tests provide the clearest answers.

Chest pain is one of the most common reasons people present to both emergency departments and private clinics — and it is also one of the most anxiety-provoking. When your chest hurts, the mind immediately goes to the worst-case scenario: a heart attack. That fear is understandable, and it is not entirely misplaced. But the clinical reality is considerably more nuanced. In primary care settings, musculoskeletal problems are the most common cause of chest pain, followed by cardiovascular disease — with ischaemic heart disease, psychogenic causes, and respiratory conditions each accounting for roughly 10% of cases[1].

The challenge — for patients and clinicians alike — is that the clinical presentation of chest pain does not reliably distinguish between its causes. A patient with severe anxiety can describe chest pain that is clinically indistinguishable from cardiac angina[3]. Conversely, some patients with acute myocardial infarction present with atypical or mild symptoms. This is precisely why structured clinical assessment — rather than self-diagnosis — is the appropriate response to chest pain that is new, recurrent, or associated with any concerning features.

Types of Chest Pain and Their Possible Causes

NICE classifies the causes of chest pain into five broad categories: cardiac, pulmonary, vascular, gastrointestinal, musculoskeletal, and other causes including psychological disorders[4]. Understanding which category your symptoms most closely resemble is a useful starting point — but it is not a substitute for clinical assessment, because significant overlap exists between categories and because the consequences of missing a cardiac cause are severe.

CategoryCommon CausesTypical FeaturesUrgency
CardiacAcute coronary syndrome (ACS), angina, myocarditis, pericarditisCentral, heavy, pressure or squeezing; may radiate to arm, jaw, or back; worsened by exertionPotentially life-threatening — urgent assessment required
VascularAortic dissection, pulmonary embolismSudden severe tearing pain (dissection); pleuritic pain with breathlessness (PE)Life-threatening — call 999
MusculoskeletalCostochondritis, chest wall muscle strain, rib injury, cervical spine pathologyLocalised, sharp, reproducible on palpation or movement; worsened by specific positionsLow urgency — but requires assessment to exclude cardiac cause
GastrointestinalGastro-oesophageal reflux (GORD), oesophageal spasm, peptic ulcerBurning, worse after meals or lying down; may respond to antacidsLow-moderate urgency — cardiac cause should be excluded first
PulmonaryPneumonia, pneumothorax, pleuritisSharp, worsened by breathing or coughing; may be associated with fever or breathlessnessModerate — requires assessment; pneumothorax can be urgent
PsychologicalAnxiety, panic disorder, somatisationVariable; often associated with palpitations, hyperventilation, sweating; gradual onsetLow cardiac urgency — but significant quality-of-life impact; cardiac cause must be excluded
OtherHerpes zoster (shingles), anaemia, sickle cell crisisDermatomal distribution (shingles); exertional symptoms with anaemiaVaries — requires clinical assessment

Non-cardiac chest pain (NCCP) — defined as recurrent chest pain indistinguishable from ischaemic heart pain after a cardiac cause has been excluded — has a lifetime prevalence of 20–33% in the general population[5]. It is, in other words, extremely common. Gastro-oesophageal reflux disease (GORD) is the most common underlying cause of NCCP, followed by oesophageal dysmotility and functional chest pain[2]. Psychological comorbidities — particularly panic disorder, anxiety, and depression — are present in 35–79% of patients with NCCP and significantly influence symptom severity and healthcare utilisation[6].

The critical clinical point is this: NCCP can only be diagnosed after a cardiac cause has been excluded. The history, physical examination, and initial investigations — particularly the ECG and cardiac biomarkers — are the tools that make that exclusion possible. Reassurance without investigation is not appropriate clinical practice for chest pain, regardless of how benign the presentation appears.

When Chest Pain Is an Emergency: Call 999

The 2021 AHA/ACC Guideline on Chest Pain is unambiguous: patients with acute chest pain or chest pain equivalent symptoms should seek medical care immediately by calling emergency services[3]. The following symptoms require an immediate 999 call — do not drive yourself to hospital, and do not wait to see if the symptoms improve.

Call 999 Immediately — Do Not Wait

Severe central chest pain, pressure, or tightness

Particularly if it feels like a heavy weight on the chest or a squeezing sensation

Pain radiating to the arm, jaw, neck, or back

Radiation to the left arm or jaw is a classic feature of acute myocardial infarction

Chest pain with breathlessness

The combination of chest pain and shortness of breath at rest is a high-risk presentation

Chest pain with sweating, nausea, or vomiting

Autonomic symptoms accompanying chest pain significantly increase the probability of ACS

Sudden, tearing or ripping chest pain

Suggests aortic dissection — a life-threatening vascular emergency requiring immediate CT

Chest pain with collapse or loss of consciousness

Suggests haemodynamic compromise — requires immediate resuscitation assessment

Chest pain with severe breathlessness and leg swelling

May indicate pulmonary embolism — a potentially fatal clot in the pulmonary arteries

Chest pain in a patient with known heart disease

Any new chest pain in a patient with established coronary artery disease is a cardiac emergency until proven otherwise

Important: Women, older patients, and people with diabetes may present with atypical symptoms — nausea, fatigue, jaw pain, or breathlessness without prominent chest pain. The AHA/ACC Guideline notes that women are more likely to present with accompanying symptoms such as nausea and shortness of breath[3]. If in doubt, call 999.

When to See a Cardiologist (Not an Emergency, But Needs Assessment)

Not all chest pain requires a 999 call. There is a substantial category of chest pain that is not an acute emergency but does require prompt clinical assessment — ideally within days rather than weeks. The following presentations warrant a cardiology or private GP assessment rather than watchful waiting.

Seek Assessment Within Days — Not an Emergency, But Important

Recurrent chest pain that comes and goes

Particularly if it occurs with exertion or stress — may indicate stable angina

Chest pain with palpitations

The combination suggests a possible arrhythmia contributing to symptoms

Chest tightness or discomfort on exertion

Exertional chest symptoms are a classic presentation of stable coronary artery disease

Chest pain in a patient with cardiovascular risk factors

Hypertension, high cholesterol, diabetes, smoking, or family history of heart disease increase the probability of a cardiac cause

Unexplained chest pain lasting more than a few minutes

Brief, stabbing pain lasting seconds is less likely to be cardiac; pain lasting minutes warrants investigation

Chest pain associated with breathlessness on exertion

May indicate reduced cardiac reserve — warrants echocardiogram and cardiology assessment

At Victoria Medical, our private cardiologist offers same-day and next-day appointments for patients with chest pain that requires assessment but is not an acute emergency. A comprehensive initial assessment — including history, examination, resting ECG, and cardiac blood tests — can be completed within a single appointment, with results available the same day.

Tests for Chest Pain: ECG, Echocardiogram, and Blood Markers

The diagnostic pathway for chest pain is built around three complementary investigations: the resting ECG (which assesses the heart's electrical activity), cardiac biomarkers in the blood (which detect myocardial injury), and the echocardiogram (which images the heart's structure and function). Understanding what each test does — and what it cannot do — helps you understand why your doctor may recommend more than one investigation even after a normal initial result.

TestWhat It MeasuresDurationKey DiagnosesLimitation
12-lead ECGElectrical activity of the heart at rest5 minutesST-elevation MI (STEMI), arrhythmias, conduction defects, LVH, pericarditis patternNormal in ~50% of ACS at presentation; does not assess structure
High-sensitivity troponin (blood)Cardiac muscle protein released during myocardial injuryBlood draw + lab analysisAcute myocardial infarction (NSTEMI, STEMI), myocarditisElevated in other conditions (PE, renal failure); requires serial testing
EchocardiogramHeart structure, wall motion, valve function, ejection fraction30–45 minutesValvular disease, cardiomyopathy, pericardial effusion, regional wall motion abnormalityDoes not directly image coronary arteries; operator-dependent
Exercise ECG (stress test)ECG changes during controlled physical exertion30–60 minutesStable coronary artery disease (exercise-induced ST changes)Lower sensitivity than imaging stress tests; not suitable for all patients
CT coronary angiography (CTCA)Anatomical imaging of coronary arteries30–60 minutesCoronary artery disease, stenosis, calcificationRadiation exposure; requires contrast; not suitable for all patients
Chest X-rayLung fields, heart size, aortic silhouette5 minutesPneumothorax, pneumonia, heart failure, aortic wideningLimited cardiac detail; does not assess coronary arteries

The Resting ECG: Essential First Step

The 12-lead resting ECG is the first investigation recommended for all patients presenting with chest pain[3]. It takes five minutes, is entirely non-invasive, and can identify ST-elevation myocardial infarction (STEMI) — the most time-critical cardiac emergency — immediately. It can also detect arrhythmias, conduction abnormalities, signs of pericarditis, left ventricular hypertrophy, and pre-existing conduction disease that may influence the interpretation of subsequent investigations.

The important limitation to understand is that a normal resting ECG does not exclude acute coronary syndrome. Approximately 50% of patients with non-ST-elevation myocardial infarction (NSTEMI) have a normal or non-specifically abnormal ECG at initial presentation. This is why the ECG is always interpreted alongside the clinical history and cardiac biomarkers — not in isolation. At Victoria Medical, our private ECG test is available same-day, with results reviewed immediately by our clinical team.

Cardiac Troponin: The Gold Standard Biomarker

Cardiac troponins (troponin I and troponin T) are proteins released into the bloodstream when cardiac muscle cells are damaged. High-sensitivity cardiac troponin assays are now the preferred standard for the biomarker diagnosis of acute myocardial infarction, as recommended by the 2021 AHA/ACC Guideline[3]. They allow more accurate detection and, crucially, more accurate exclusion of myocardial injury — meaning a low troponin result on a high-sensitivity assay provides strong evidence against an acute MI.

Troponin is not a standalone test. It must be interpreted in the context of the clinical history, the ECG, and the time elapsed since symptom onset — troponin rises 3–6 hours after the onset of myocardial injury and may be undetectable in the very early stages of an acute event. Serial troponin measurements (at 0 and 1–3 hours) are standard practice in emergency settings to detect the characteristic rise-and-fall pattern of acute MI. Our private blood test service includes cardiac biomarker panels for patients presenting with chest pain outside the emergency setting.

The Echocardiogram: Assessing Cardiac Structure

An echocardiogram is an ultrasound scan of the heart that images its physical structure — chambers, valves, wall motion, and pumping function. For patients with chest pain, it is the investigation of choice when structural heart disease is suspected: valvular disease, hypertrophic cardiomyopathy, pericardial effusion, or reduced left ventricular ejection fraction. It can also identify regional wall motion abnormalities — areas of the heart wall that are not contracting normally — which may indicate previous or ongoing ischaemia.

For patients with stable chest pain and intermediate-to-high pre-test probability of coronary artery disease, stress echocardiography — where the echocardiogram is performed during pharmacological stress or exercise — provides both functional and structural information about the heart's response to increased demand. The 2021 AHA/ACC Guideline recommends echocardiography or stress echocardiography as one of the preferred imaging modalities for intermediate-to-high risk patients with stable chest pain[3]. Our private echocardiogram service is performed by a consultant cardiologist and provides a comprehensive assessment of cardiac structure and function.

Musculoskeletal and Non-Cardiac Causes of Chest Pain

Once a cardiac cause has been excluded, the most common diagnosis in primary care is musculoskeletal chest pain — accounting for 20–50% of chest pain presentations in general practice[1]. Costochondritis (inflammation of the cartilage connecting the ribs to the sternum), chest wall muscle strain, and cervical or thoracic spine pathology are the most frequent musculoskeletal diagnoses. These conditions typically produce pain that is localised, sharp, reproducible on palpation of the chest wall, and worsened by specific movements or positions — features that help distinguish them from cardiac pain, though not reliably enough to avoid investigation.

Gastro-oesophageal reflux disease (GORD) is the most common cause of non-cardiac chest pain overall, accounting for up to 60% of NCCP cases in some series[2]. Oesophageal spasm can produce severe, crushing central chest pain that is clinically indistinguishable from cardiac angina — including radiation to the arm and jaw, and relief with nitrates. This is one of the most important diagnostic pitfalls in chest pain assessment.

Psychological causes — particularly panic disorder and anxiety — account for approximately 10% of chest pain presentations in primary care[1]. Psychological comorbidities are present in 35–79% of patients with non-cardiac chest pain and significantly amplify symptom severity and healthcare utilisation[6]. Importantly, anxiety-related chest pain should only be attributed to anxiety after cardiac and other organic causes have been excluded — not as a default diagnosis in the absence of investigation.

Features More Consistent with Non-Cardiac Chest Pain

These features make a non-cardiac cause more likely — but do not exclude a cardiac cause without investigation.

Pain that is sharp, stabbing, or very brief (seconds)

Pain that is clearly reproducible by pressing on the chest wall

Pain that is worsened by specific movements or positions

Pain that is clearly related to meals, lying down, or bending forward

Pain associated with heartburn, regurgitation, or acid taste

Pain that occurs during or after anxiety or panic episodes

Pain in a young patient with no cardiovascular risk factors

Pain that has been present unchanged for months or years

What to Do If You Have Chest Pain

The appropriate response to chest pain depends on its severity, associated symptoms, and your individual risk profile. The following framework provides a practical guide — but when in doubt, always err on the side of seeking assessment rather than waiting.

1

Severe, acute, or alarming symptoms → Call 999

If your chest pain is severe, sudden, associated with breathlessness, sweating, radiation to the arm or jaw, or collapse — call 999 immediately. Do not drive yourself to hospital. Do not wait to see if it improves.

2

Recurrent, exertional, or unexplained symptoms → Cardiology assessment within days

If your chest pain is recurrent, occurs with exertion, or is associated with palpitations or breathlessness — book a cardiology assessment promptly. A resting ECG, cardiac biomarkers, and clinical history will guide the next steps.

"The patients who concern me most with chest pain are not those who come in immediately — they are the ones who wait. I see patients who have had recurrent episodes of exertional chest tightness for months, dismissing it as indigestion or anxiety, who turn out to have significant coronary artery disease. The clinical history is the most powerful diagnostic tool we have, and a five-minute ECG can provide enormous reassurance — or identify something that needs urgent attention. Chest pain that is new, recurrent, or associated with any other symptom deserves investigation. The cost of a missed diagnosis is simply too high to justify waiting."

Frequently Asked Questions

Can anxiety cause chest pain that feels like a heart attack?

Yes — anxiety and panic disorder can produce chest pain that is clinically indistinguishable from cardiac angina, including central tightness, radiation, and associated breathlessness. However, anxiety-related chest pain should only be attributed to anxiety after a cardiac cause has been excluded with an ECG and blood tests. The two can coexist, and an underlying arrhythmia or structural problem can itself trigger anxiety.

My ECG was normal. Does that mean my chest pain is not cardiac?

Not necessarily. A normal resting ECG means no abnormality was detected at the time of the recording — but it does not exclude coronary artery disease, which may only manifest during exertion, or NSTEMI, which may not produce ST-elevation changes. If your symptoms are recurrent or exertional, further investigation — including cardiac biomarkers, an echocardiogram, or a stress test — is appropriate.

What is the difference between angina and a heart attack?

Angina is chest pain caused by reduced blood flow to the heart muscle during periods of increased demand (typically exertion or stress), which resolves with rest or nitrates. A heart attack (myocardial infarction) occurs when a coronary artery is completely blocked, causing permanent damage to the heart muscle. Angina pain typically resolves within minutes; heart attack pain is usually more severe, prolonged, and does not resolve with rest.

How quickly can I get a chest pain assessment at Victoria Medical?

Same-day and next-day appointments are available for chest pain assessment at Victoria Medical. A comprehensive initial assessment — including consultation, 12-lead ECG, and cardiac blood tests — can be completed within a single appointment. Echocardiogram is available at the same clinic, typically within 24–48 hours if required.

Do I need a GP referral to see a cardiologist for chest pain?

No — at Victoria Medical, you can book directly with our consultant cardiologist without a GP referral. If you would prefer to start with a GP assessment, our private GP can complete the initial workup and refer you to the cardiologist on the same day if indicated.

What is costochondritis and how is it treated?

Costochondritis is inflammation of the cartilage that connects the ribs to the sternum (breastbone). It produces localised chest pain that is typically sharp, reproducible on pressing the affected area, and worsened by movement or deep breathing. It is a benign condition that usually resolves with anti-inflammatory medication and rest. However, it should only be diagnosed after a cardiac cause has been excluded — the presentations can overlap.
