Chest Pain: When Is It an Emergency?
Chest pain is one of the most common reasons people attend an emergency department, and one of the most difficult symptoms to interpret at home. Most chest pain is not caused by the heart. But because cardiac causes carry the highest risk, the safest approach is to have new or unexplained chest pain assessed rather than reasoned away.
Features that raise concern for a cardiac cause
Discomfort that is central rather than pinpoint, described as pressure or heaviness rather than sharp; brought on by physical effort or emotional stress; spreading to the arm, jaw, neck or back; accompanied by breathlessness, sweating or nausea; and lasting more than a few minutes.
Discomfort that comes on with exertion and eases with rest is a particularly important pattern, because it suggests the heart muscle is not receiving enough blood when demand rises.
Common non-cardiac causes
Acid reflux can cause burning discomfort behind the breastbone, often after meals or when lying down. Muscular and rib-related pain is usually sharp, reproducible when you press on the area, and worse with certain movements. Anxiety can produce genuine chest tightness alongside rapid breathing. Lung conditions may cause pain that worsens on deep breathing or coughing.
These causes are common — but they cannot be reliably distinguished from cardiac pain at home, particularly in someone with risk factors.
When to seek emergency help immediately
Call emergency services if chest discomfort is severe, comes on suddenly, lasts more than a few minutes, or occurs with breathlessness, sweating, nausea or fainting. The same applies if discomfort spreads to the arm, jaw or back, or if you have known heart disease and your usual pattern has changed.
It is always better to be assessed and reassured than to wait at home.
When to book a cardiology appointment
Chest discomfort that is mild but recurrent, that reliably appears with exertion, or that is new in someone with risk factors such as diabetes, high blood pressure, high cholesterol, smoking or a family history, should be assessed without long delay. Investigation may include an ECG, an echocardiogram, a treadmill test or coronary angiography, depending on the clinical picture.
Frequently asked questions
Can chest pain be caused by gas or acidity?
Yes, acid reflux is a common cause of chest discomfort and can closely mimic cardiac pain. Because the two cannot be reliably separated without assessment, new or severe chest pain should not be assumed to be acidity.
I am young and healthy. Could my chest pain still be cardiac?
It is less likely, but not impossible. Heart attacks are occurring at younger ages, particularly where diabetes, smoking, high blood pressure or a strong family history are present.
What tests are used to investigate chest pain?
Assessment usually begins with an ECG and blood tests. Depending on findings, an echocardiogram, treadmill test, CT coronary angiogram or invasive coronary angiography may follow.
Does chest pain always mean a blocked artery?
No. Many causes are non-cardiac, and even cardiac chest pain has several possible mechanisms. Assessment is what distinguishes them.
