Cardiac Symptom

Chest Pain
and Tightness

One of the most important symptoms to assess — chest pain has many causes, cardiac and non-cardiac. Expert evaluation gets to the answer quickly and without delay.

Chest pain assessment by Dr Nijjer, Consultant Cardiologist at Harley Street London

Overview

About Chest Pain
and Tightness

Chest pain or tightness is one of the most frequent reasons people attend emergency departments — and one of the most important symptoms a cardiologist needs to assess carefully. The cause may be cardiac or entirely unrelated to the heart.

Many patients are referred to a Rapid Access Chest Pain Clinic — typically a nurse-led service — before seeing a specialist. Dr Nijjer provides a complete and unhurried cardiological assessment that identifies the cause quickly, often within a single appointment, and initiates the right treatment without delay.

Dr Nijjer will take a thorough description of your symptoms, review your medical and family history, perform a clinical examination, and arrange the appropriate cardiac investigations. If the cause turns out to be non-cardiac, he will direct you to the right specialist.

Before Your Appointment

Understanding Your Symptoms

Thinking carefully about the nature of your discomfort before attending your clinic appointment will help Dr Nijjer reach a diagnosis more quickly. Try to reflect on the following questions:

The more precisely you can describe your symptoms — including what triggers them and what relieves them — the faster and more accurately Dr Nijjer can identify the cause.

There is no need to worry if you find some questions difficult to answer — the consultation is structured to help you articulate your experience, however vague the symptoms may feel.

?

Is the pain sharp and stabbing, or dull and heavy — like a band across the chest?

?

Does it come on at rest, lying down, or only when you exert yourself?

?

Does taking a deep breath make the chest pain worse?

?

Is your breathing affected when the discomfort occurs?

?

Is the discomfort worse after eating, or associated with a burning or reflux sensation?

?

Is it triggered or made worse by stress or emotional strain?

?

Does the pain radiate into your arm, jaw, or back?

?

Is there nausea, sweating, or dizziness associated with the pain?

Differential Diagnosis

What Causes Chest Pain
or Tightness?

There are many potential explanations for chest pain — some cardiac, others entirely unrelated to the heart. Dr Nijjer will systematically work through the possibilities to identify the correct cause. The main categories are:

Cardiac causes of chest pain — specialist assessment by Dr Nijjer

Cardiac causes account for many cases of chest pain or tightness requiring specialist investigation

Most Important to Rule Out

Cardiac Causes of
Chest Pain

Cardiac causes must be identified or excluded before other explanations are considered. They range from stable angina — manageable with medication and lifestyle — to immediately life-threatening heart attacks requiring emergency treatment.

Angina

Recurrent chest tightness on exertion, relieved by rest. Caused by insufficient blood supply through narrowed coronary arteries. Should not be ignored — requires investigation and treatment.

Angina →

Unstable Angina

Chest discomfort occurring at rest or with minimal activity, often worsening rapidly. Caused by a coronary narrowing that has suddenly deteriorated. Requires prompt investigation and treatment.

Coronary Heart Disease →

Heart Attack

Chest pain with breathlessness, nausea, and feeling unwell. Pain lasting longer than 20 minutes is a medical emergency — call 999 immediately and do not drive to hospital.

Heart Attack →

Coronary Microvascular Disease

The small vessels deep within the heart muscle fail to respond normally, causing angina-like symptoms. More common in patients with diabetes. Requires specialist testing to diagnose accurately.

Microvascular Angina →

Coronary Vasospasm

Recurrent chest pain consistent with angina, but with apparently normal coronary arteries. The artery intermittently spasms shut, often without warning. Requires specialist assessment to identify and treat.

Coronary Vasospasm →

Pericarditis

Sharp chest discomfort worse with breathing and improved in certain positions — caused by infection of the pericardium (the outer lining of the heart). Diagnosed with ECG, echocardiogram, and blood tests.

Myocarditis

Inflammation of the heart muscle, typically triggered by a viral infection. A serious condition requiring specialist investigation including cardiac MRI to assess the extent of involvement.

Arrhythmia & Valve Disease

Rapid or irregular heartbeats can cause chest tightness, particularly if underlying coronary narrowings are present. Valve problems such as aortic stenosis can also cause exertional chest pain as outflow from the heart is restricted.

Heart Valve Disease →

Non-Cardiac Causes

Other Causes of
Chest Discomfort

Not all chest pain originates in the heart. Once cardiac causes have been assessed, Dr Nijjer will consider other explanations and, if needed, refer to the appropriate specialist for treatment.

Lung Causes

  • Pulmonary Embolus Clots forming in the deep veins of the legs or pelvis can travel to the lungs and cause a dangerous blockage. Requires urgent assessment and specialist imaging to detect and treat.
  • Lung Infection Bacterial or viral pneumonia causes chest discomfort often accompanied by fever and cough. Patients with COPD, emphysema, or bronchiectasis may experience recurrent episodes.
  • Lung Inflammation Inflammatory lung conditions — including pleuritis and pulmonary fibrosis — can cause pain that worsens on breathing. Blood tests and chest X-ray help differentiate these from cardiac causes.

Gastric Causes

  • Gastric Reflux The stomach and oesophagus are common sources of chest discomfort. Symptoms are typically worse after eating, with coffee or acidic foods, and may include a burning sensation or acid taste in the mouth.
  • Excessive Acid & Gastric Ulceration Excess acid production can cause ulceration. Recurrent pain worsened by eating may warrant endoscopy.
  • Helicobacter Pylori A bacterial stomach infection that triggers excess acid production, requiring targeted antibiotic treatment to clear.

Musculoskeletal Causes

  • Chest Muscle Injury Injury from exercise or awkward lifting can cause a constant throbbing discomfort, often localised to a specific area and worsened by movement or pressure.
  • Costochondritis Viral inflammation of the cartilage around the rib cage causes a sharp, recurrent discomfort that worsens when the chest is pressed. Often confused with cardiac pain.
  • Shingles Reactivation of the chickenpox virus within nerve endings can cause severe chest and back pain, followed by a characteristic blistering rash along the affected dermatome.

Anxiety & Stress

  • Panic Attacks & Hyperventilation Work-related stress and anxiety are significant causes of chest symptoms. Panic attacks produce a raised heart rate, breathlessness, and chest tightness that can mimic cardiac pain. Thyroid disorders — particularly an overactive thyroid — can produce identical symptoms and are diagnosed by a simple blood test.
  • Chronic Stress Prolonged psychological stress elevates blood pressure and can cause musculoskeletal chest tension. It is also an important risk factor for coronary heart disease itself. Addressing stress is a core part of cardiovascular health management.

Assessment

What Tests Are Needed
for Chest Pain?

Dr Nijjer assesses symptoms carefully before selecting the most appropriate investigations. Bringing any previous blood test results, ECG tracings, or health screen reports to your appointment helps streamline the assessment.

A clinical examination will check for heart murmurs and signs of heart failure. Core investigations include:

  • ECGA rapid snapshot of the heart's electrical activity. Essential but a normal result does not exclude significant coronary disease.
  • EchocardiogramUltrasound assessment of heart pump function, valve structure, and wall motion abnormalities.
  • Blood testsIncluding cardiac enzymes, cholesterol profile, blood sugar, kidney function, and thyroid function.
  • CT Coronary AngiogramNon-invasive imaging of the coronary arteries. Measures calcium score and identifies soft plaque and narrowings.
  • Stress TestingExercise or pharmacological stress test to provoke symptoms and assess the heart's response under demand.
  • Invasive AngiographyThe gold standard for direct visualisation of the coronary arteries, performed through the wrist artery as a day-case procedure.

Dr Nijjer is an internationally recognised expert in pressure-wire physiology (iFR), allowing precise measurement of blood flow within the coronary arteries during the same procedure as angiography.

Management

Treating Chest
Pain and Tightness

Treatment is entirely dependent on the cause. Once the diagnosis is established through clinical assessment and investigation, Dr Nijjer will develop a personalised management plan.

For cardiac causes such as stable angina, treatment typically combines lifestyle changes, risk factor management, and medications — with coronary intervention reserved for cases where narrowings are proven to be restricting blood flow. For unstable angina or heart attack, urgent treatment is needed.

For non-cardiac causes — whether pulmonary, gastric, musculoskeletal, or anxiety-related — Dr Nijjer will initiate appropriate treatment or coordinate a referral to the right specialist.

Dr Nijjer combines the latest International Guidelines with a holistic, patient-centred approach — tailoring his recommendation to fit into your life, not the other way around.

When chest pain is an emergency — call 999 immediately

Do not drive yourself. Chew one 300 mg aspirin if you are not allergic. Call 999 if your chest pain is:

  • Severe, central, crushing or heavy — lasting more than 15 minutes and not relieved by rest
  • Spreading to the jaw, neck, shoulder or arm
  • Accompanied by breathlessness, sweating, nausea or feeling faint
  • New and unfamiliar, especially with heart disease risk factors

Paramedics can begin treatment on the way to hospital, which significantly improves outcomes.

What does heart-related chest pain feel like?

Heart-related chest pain typically feels like a heavy pressure, tightness, squeezing or band-like discomfort in the centre of the chest, rather than a sharp or stabbing pain. Many patients describe it as "an elephant sitting on my chest" or "a tight belt" — rather than what most people picture as pain at all.

The discomfort often radiates to the left arm, jaw, neck, back or upper abdomen, and is usually brought on by exertion, emotional stress or a heavy meal. Importantly, cardiac chest pain is rarely affected by breathing in deeply or pressing on the chest wall — if your pain changes with either of those, a non-cardiac cause is more likely, though it does not exclude heart disease entirely.

How do I tell the difference between a heart attack and anxiety?

A panic attack and a heart attack can feel uncannily alike, but several features help separate them. Panic attacks usually peak within ten minutes and ease with calming techniques, while heart attack pain tends to build, persist beyond fifteen minutes and worsen with exertion.

Panic-related chest pain is more often sharp, localised to one spot, and accompanied by tingling in the fingers or around the mouth from over-breathing. Heart attack pain is more often central, pressure-like, spreads to the arm or jaw, and comes with cold sweat or nausea. If you are unsure, treat it as cardiac and call 999 — only an ECG and blood tests can reliably tell them apart.

"Chest pain is the most common reason patients are referred to me, and the vast majority of cases turn out to have a reassuring explanation. What I always say is: the time to worry about chest pain is before we investigate it. Once we've done the right tests, most patients leave with genuine peace of mind — and the small number who do have something treatable are in exactly the right place."

— Dr Sukhjinder Nijjer, Consultant Cardiologist, Harley Street

Can chest pain be caused by indigestion or reflux?

Yes — gastro-oesophageal reflux (GORD) is one of the most common causes of chest pain seen in clinic, and it can mimic angina very closely. The oesophagus and the heart share nerve pathways, so acid irritation can produce burning, tightness or even a crushing sensation behind the breastbone.

Clues pointing towards reflux include a burning quality, relief with antacids, a sour taste in the mouth, symptoms worse when lying flat or after eating, and a long history of similar episodes that have never escalated. That said, the overlap with cardiac pain is significant enough that new or changing chest pain should always be properly assessed before being labelled as reflux.

Why does my chest hurt when I breathe in?

Pain that sharpens when you breathe in — called pleuritic pain — usually points to the lining of the lungs, the chest wall or the pericardium (the sac around the heart), rather than the heart muscle itself. Common causes include muscle strain, costochondritis (inflammation of the rib cartilage), a chest infection, or pericarditis.

Pericarditis can feel very alarming because the pain is often severe and central, but it characteristically eases when you lean forward and worsens when you lie flat. A pulmonary embolus (blood clot in the lung) is a more serious cause of pleuritic pain and needs urgent assessment — especially if combined with breathlessness, a fast heart rate or a recent long flight or surgery.

Dr Nijjer's clinical perspective Consultant Cardiologist · Lead, Cardiac Catheter Labs, Hammersmith Hospital

Chest pain is never something I dismiss without a thorough assessment. I have had patients come to me who had been told their pain was anxiety for months — only to find significant coronary artery disease on CT scanning. Even when the heart turns out to be perfectly healthy, which is frequently the case, having that confirmed provides genuine peace of mind.

My approach combines clinical history, a resting ECG, and almost always an echocardiogram at the same visit. Where coronary disease is suspected, I arrange CT coronary angiography and, if needed, coronary pressure wire assessment (iFR) to determine exactly whether a vessel is causing symptoms. Exercise-related chest pain, in particular, should always be assessed by a cardiologist — a stress echocardiogram can be highly informative in these cases.

Chest pain: when to call 999 immediately

These features suggest a possible heart attack — do not drive yourself. Call 999.

Crushing central pressure

Heavy, tight, or squeezing sensation in the centre or left of the chest lasting more than 15 minutes

Pain spreading to arm or jaw

Radiation to the left arm, both arms, neck, jaw, or upper back — a classic warning sign

Cold sweats and nausea

Chest discomfort accompanied by cold sweats, nausea, vomiting, or a sense of impending doom

Breathlessness with chest pain

Sudden breathlessness alongside chest pain, or severe breathlessness at rest — call 999 now

Is left-sided chest pain always serious?

No — left-sided chest pain is not always cardiac, and very localised "pin-point" left-sided pain that you can reproduce by pressing on the chest wall is usually musculoskeletal. The heart is positioned slightly left of centre, which is why people associate the left side with cardiac problems, but cardiac pain is more often central than purely left-sided.

That said, left-sided pain that is dull, heavy, exertional or radiates into the left arm or jaw deserves prompt cardiac assessment. The reassuring features are: short stabs lasting seconds, reproducible by pressing or twisting, and no associated breathlessness, sweating or faintness.

"One of the things I find most important in clinic is listening carefully to how a patient describes their pain. The quality and character — whether it's pressure, burning, stabbing — tells me a great deal before I've even examined them. But I never rely on description alone. The tests are there to confirm what the history suggests, and sometimes to surprise us."

— Dr Sukhjinder Nijjer

How long does angina chest pain usually last?

Stable angina typically lasts a few minutes — usually 2 to 10 — and eases with rest or with a glyceryl trinitrate (GTN) spray within five minutes. Episodes brought on reliably by the same level of exertion and relieved by the same rest pattern are the hallmark of stable disease.

Pain that lasts longer than 15 minutes, comes on at rest, or is more severe than usual is a red flag for unstable angina or a heart attack and is a 999 call. A new pattern of more frequent, more easily triggered or longer-lasting episodes is also a reason to seek same-day specialist review.

What is the difference between angina and a heart attack?

Angina is chest pain caused by a temporary shortage of blood supply to the heart muscle, usually from a narrowed coronary artery — the muscle is starved but not damaged. A heart attack (myocardial infarction) occurs when blood supply is cut off long enough to kill heart muscle, almost always because a plaque has ruptured and triggered a clot.

The symptoms can feel identical at first. The key differences are duration and response to rest: angina settles within minutes, while a heart attack does not. A heart attack also produces a rise in the blood marker troponin, which is how it is confirmed in hospital. Both deserve urgent attention, but a heart attack is a 999 emergency — every minute counts.

Can chest pain come and go and still be serious?

Yes. Intermittent chest pain is exactly how stable angina presents — short episodes triggered by exertion that resolve with rest. It is also how unstable angina behaves in the days or weeks before a heart attack, with episodes becoming more frequent or occurring at rest.

A pattern of repeated short episodes — even if each one settles — is a reason to be assessed promptly. Pain that comes and goes for hours, particularly if accompanied by sweating, nausea, breathlessness or radiation to the arm or jaw, should be treated as a heart attack until proven otherwise.

"I always tell patients: if you've had the same chest discomfort reliably for years and it hasn't changed, it's very different from something new. It's the change in pattern — pain coming on more easily, lasting longer, waking you at night — that worries me clinically. Please don't dismiss a new pattern because the old one was harmless."

— Dr Sukhjinder Nijjer

Why do I get chest pain when I exercise?

Exertional chest pain that eases with rest is the textbook presentation of angina and means a coronary artery is likely narrowed by atherosclerosis. The heart muscle needs more oxygen during exercise; if a narrowing limits supply, the muscle protests.

Not every cause is cardiac — asthma, exercise-induced bronchoconstriction and chest wall strain can all do the same — but exertional chest pain should always be investigated. A CT coronary angiogram is usually the first-line test under NICE guidance for new exertional chest pain in the UK and gives a definitive answer about whether your arteries are narrowed.

Can stress or panic attacks cause real chest pain?

Yes — the chest pain of a panic attack is genuine, not imagined, and it can be intense enough to send people to A&E. It is driven by hyperventilation, muscle tension and a surge of adrenaline, producing a tight, sharp or burning sensation, often with tingling in the hands, dizziness and a sense of doom.

Chronic stress can also worsen genuine cardiac disease and is increasingly recognised as a cardiovascular risk factor. The safe approach is: if the pain is new, atypical, or you have heart disease risk factors, get a cardiac assessment first. Once the heart is cleared, the psychological component can be addressed properly.

What tests will a cardiologist do for chest pain?

The standard work-up usually begins with an ECG and blood tests including troponin and cholesterol, followed by a CT coronary angiogram if NICE criteria are met — this is the first-line imaging test for new chest pain in most UK patients.

Depending on what those tests show, further investigations may include an echocardiogram, a stress echocardiogram or cardiac MRI to look for ischaemia, or an invasive coronary angiogram if a significant blockage is suspected. You can read more about all these tests in the cardiac tests FAQ.

Should I see a cardiologist privately for chest pain?

Private cardiology assessment makes sense when you want a rapid, joined-up review — consultation, ECG, blood tests and imaging arranged within days rather than weeks. New or changing chest pain is a clinical priority and should not wait.

You can be seen privately while remaining under NHS care, and you do not always need a GP referral, although one is helpful. If your pain is severe or escalating, the right route is A&E first, with cardiology follow-up afterwards. See When should I see a cardiologist? for more on the private pathway.
