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.
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 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.
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.
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.
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.
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.
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.
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.
