Chest discomfort can be worrying, especially when it appears unexpectedly or during everyday activities. Some people notice pressure in the middle of the chest, while others experience a sharp sensation, burning, or discomfort that spreads to the back or shoulders.
The cause is not always obvious. Sometimes the discomfort is related to digestion or strained muscles. In other situations, it may indicate a problem that requires urgent medical attention.
At COR Cardiology, helping people understand heart health is an important part of informed care. This guide explains possible causes, warning signs, diagnostic tests, and when to seek medical assessment.
What Are the Most Common Causes of Chest Pain?
There are several possible explanations for discomfort in the chest. These include conditions affecting the heart, lungs, digestive system, muscles, and ribs. The symptoms alone cannot reliably establish the cause.
1. Heart-Related Conditions
Some heart conditions reduce blood flow to the heart muscle or cause inflammation around the heart.
What Is Angina?
Angina is discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. It may feel like pressure, tightness, heaviness, or squeezing.
Angina can occur during physical activity, emotional stress, or other situations that increase the heart’s workload. It often improves with rest, but new, worsening, or persistent symptoms require urgent medical assessment.
Can a Heart Attack Cause Chest Discomfort?
Yes. A heart attack occurs when blood flow to part of the heart muscle is severely reduced or blocked. Symptoms may include pressure or tightness, breathlessness, sweating, nausea, dizziness, and discomfort spreading to the arms, jaw, back, or shoulders.
Symptoms are not always severe, and some people experience less obvious warning signs. If a heart attack is suspected
2. Digestive Problems
Acid reflux occurs when stomach contents move back into the oesophagus, potentially causing a burning sensation behind the breastbone.
What Causes Chest Pain After Eating?
Possible causes of chest pain after eating include acid reflux, indigestion, and other digestive conditions. Chest pain may become noticeable after a large meal or when lying down soon after eating. It can feel like burning, pressure, or discomfort behind the breastbone.
However, chest pain after a meal should not automatically be attributed to indigestion. Heart-related conditions can also cause chest pain after eating, so new or concerning symptoms need appropriate medical assessment. If chest pain is severe, worsening, persistent, or accompanied by breathlessness, sweating, or nausea.
3. Muscle Strain and Rib Inflammation
Muscle strain can develop after lifting heavy objects, exercise, coughing, or unusual physical activity. Inflammation where the ribs meet the breastbone, known as costochondritis, can also cause localised discomfort.
The sensation may become more noticeable when moving, twisting, taking a deep breath, or pressing on the affected area.
Although these features can suggest a musculoskeletal cause, they do not completely rule out a serious heart or lung condition.
4. Lung-Related Conditions
Problems affecting the lungs or the tissues surrounding them can cause discomfort, particularly when breathing.
Possible causes include pneumonia, pleurisy, and pulmonary embolism, which is a blood clot in the lungs. Sudden breathlessness, pain when breathing, coughing up blood, or sudden severe symptoms require urgent medical assessment.
5. Anxiety and Panic Attacks
Anxiety and panic attacks may cause chest tightness, a racing heartbeat, sweating, trembling, and difficulty breathing.
These symptoms can resemble those of a heart condition. It is important not to assume anxiety is responsible for new or unexplained discomfort until potentially serious causes have been considered.
What Causes Pain on the Left or Right Side of the Chest?
The location of discomfort can provide useful information, but it cannot identify the cause by itself.
What Causes Pain on the Left Side?
Left-sided discomfort may be associated with angina, a heart attack, muscle strain, acid reflux, or lung conditions.
Heart-related symptoms can feel like pressure, squeezing, heaviness, or discomfort that spreads into the arm, neck, jaw, or back.
Is Left-Sided Pain Always a Heart Problem?
No. Several non-cardiac conditions can cause pain on the left side. However, you should not dismiss new or unexplained symptoms based on their location or intensity.
What Causes Pain on the Right Side?
Right-sided chest pain can arise from strained muscles, rib inflammation, lung conditions, acid reflux, or problems involving organs such as the gallbladder. The pain may feel sharp, dull, or uncomfortable and can sometimes worsen with movement or deep breathing.
Can Right-Sided Pain Be Heart-Related?
Yes. Although some people associate heart problems mainly with the left side, heart-related discomfort can occur in different areas of the chest and upper body. Seek urgent help if symptoms are severe, worsening, or accompanied by warning signs.
What Are the Warning Signs That Require Urgent Attention?
Recognising concerning symptoms can help you act promptly.
Which Symptoms May Indicate a Heart Attack?
Warning signs can include:
- Pressure, heaviness, squeezing, or tightness in the chest.
- Discomfort spreading to the arms, shoulders, neck, jaw, or back.
- Shortness of breath.
- Nausea or vomiting.
- Cold sweats.
- Dizziness, light-headedness, or fainting.
Some people, including women, may experience less typical symptoms such as unusual fatigue, breathlessness, nausea, or discomfort in the back or jaw.
Why Can Discomfort Occur After Exercise?
Physical activity increases the heart’s demand for oxygen. If blood flow to the heart muscle is restricted, angina may occur during exercise or shortly afterwards.
Muscle strain and breathing-related conditions can also cause symptoms following activity.
Should You Ignore Discomfort That Improves With Rest?
No. Although angina may improve with rest, relief does not mean the underlying cause is harmless. New symptoms, symptoms occurring with less activity than usual, or symptoms that persist despite resting need prompt medical attention.
If discomfort is severe or accompanied by emergency warning signs, call 000.
How Is Chest Pain Diagnosed?
The appropriate investigation depends on the symptoms, medical history, examination findings, and potential risks.
Can an ECG Help Identify Heart-Related Pain?
Yes. An electrocardiogram (ECG) records the heart’s electrical activity and can help identify certain abnormalities associated with a heart attack or other heart conditions.
However, a normal ECG does not rule out every heart problem. Further tests may be required depending on the clinical situation.
What Other Tests May Be Recommended?
Blood Tests
Blood tests, including troponin measurements, can help detect heart muscle injury. Doctors may need repeat measurements depending on when symptoms began.
Echocardiogram
An echocardiogram uses ultrasound to assess the heart’s structure, valves, and pumping function. It may be recommended when additional information about the heart is needed.
Exercise Testing and Other Imaging
Depending on the suspected cause, clinicians may consider stress testing, chest X-rays, CT scans, or other investigations.
Not every patient requires every test. The medical team determines the appropriate approach based on the presentation and urgency.
What Do Australian Heart Health Statistics Tell Us?
The Australian Institute of Health and Welfare (AIHW) estimated 57,100 acute coronary events in Australians aged 25 and over in 2023, equivalent to approximately 156 events per day. The estimate includes acute coronary events, such as heart attacks and other acute coronary syndromes.
This figure highlights the importance of recognising warning signs and seeking timely care. It does not mean that every episode of discomfort is heart-related; rather, it reinforces why potentially serious symptoms should be assessed appropriately.
When Should You Contact COR Cardiology in Ormeau?
If you have recurring symptoms, discomfort during activity, or concerns about your heart health, speak with your GP or an appropriate healthcare professional about the next steps.
COR Cardiology provides cardiology services in Ormeau. Depending on your circumstances, a clinician may recommend a cardiology consultation or investigations such as an ECG or echocardiogram.
A specialist assessment can help determine which investigations are appropriate. However, a routine appointment is not a substitute for emergency care when a heart attack is suspected.
How Can You Prepare for a Consultation?
If it is safe to do so, make a note of:
- When the symptoms started and how long they lasted.
- Where the discomfort occurred and how it felt.
- Whether it happened during activity, after eating, or at rest.
- Any associated symptoms, such as dizziness or breathlessness.
- Your current medicines and relevant medical history.
Do not delay emergency care to collect this information.
Conclusion
Discomfort in the chest can have several causes, ranging from digestive problems and muscle strain to serious heart and lung conditions. Its location, intensity, and timing may offer clues, but they cannot confirm the diagnosis.
Recognising warning signs, understanding when to seek urgent help, and undergoing appropriate medical assessment are important steps in protecting your health.
