How can I tell the difference between heartburn, anxiety, and angina chest pain? 

Chest pain is one of the most common reasons people visit A&E, but not all chest pain is related to the heart. It can be difficult to tell the difference between angina (a heart condition), heartburn (acid reflux), and anxiety, as they all occur in the chest area and can share overlapping symptoms. Understanding the specific qualities of pain, what triggers it, and how long it lasts can help you determine the likely cause and seek the appropriate care.

What is the main difference between angina, heartburn, and anxiety chest pain? 

The main difference lies in the ‘quality’ of the pain and its triggers. Angina typically feels like a heavy pressure or squeezing caused by exertion and relieved by rest. Heartburn is a burning sensation behind the breastbone, usually triggered by eating and worse when lying down. Anxiety often presents as a sharp, stabbing pain or tightness accompanied by palpitations and hyperventilation, often occurring at rest during stress. 

 
Quick Identification Guide 

• Angina: ‘Squeezing’ or ‘heavy.’ Linked to physical effort. 

• Heartburn: ‘Burning.’ Linked to food or position. 

• Anxiety: ‘Stabbing’ or ‘racing.’ Linked to emotional stress or panic. 

Detailed Breakdown of Symptoms 

Angina (Coronary Artery Disease) 

Angina is a symptom of reduced blood flow to the heart muscle. 

• Sensation: Dull ache, heaviness, tightness, or pressure (like a band around the chest). 

• Radiation: Pain often spreads to the left arm, neck, jaw, or back. 

• Duration: Usually lasts 3–5 minutes, as is also specified by NHS. 

• Relief: Improves with rest or GTN spray. 

 
Heartburn (GORD/Acid Reflux) 

Heartburn is caused by stomach acid leaking up into the oesophagus. 

• Sensation: distinct burning feeling rising from the stomach to the throat. 

• Taste: Often accompanied by an acidic or sour taste in the mouth. 

• Duration: Can last for hours; often worse at night. 

• Relief: Improves with antacids or sitting upright. 

 
Anxiety (Panic Attack) 

Anxiety causes physical symptoms due to the release of stress hormones (adrenaline). 

• Sensation: Sharp, stabbing pains (lasting seconds) or persistent tightness. 

• Associated signs: Palpitations, dizziness, tingling in fingers, shaking, or hyperventilation. 

• Duration: A panic attack typically peaks within 10 minutes but residual soreness can last longer. 

• Relief: Breathing exercises and calming techniques. 

 
Causes 

Angina is caused by narrowed arteries restricting oxygen to the heart (ischaemia). Heartburn is caused by a weak muscle ring (sphincter) allowing acid to escape the stomach. Anxiety chest pain is caused by muscle tension and the physiological ‘fight or flight’ response, which increases heart rate and muscle rigidity. 

• Angina Causes: Atherosclerosis (plaque buildup), smoking, high cholesterol, hypertension. 

• Heartburn Causes: Hiatus hernia, obesity, pregnancy, certain medications. 

• Anxiety Causes: Chronic stress, panic disorders, phobias, or sudden emotional shock. 

 
Triggers 

Identifying what you were doing when the pain started is one of the most reliable ways to differentiate these conditions. Angina is ‘demand-led,’ meaning it happens when the heart works hard. Heartburn is ‘chemical/mechanical,’ triggered by digestion and gravity. Anxiety is ‘emotional/physiological,’ triggered by stress or spontaneous panic. 

• Angina Triggers: Walking uphill, cold weather, heavy lifting, emotional stress (which raises heart rate). 

• Heartburn Triggers: Spicy or fatty foods, caffeine, alcohol, lying flat immediately after eating. 

• Anxiety Triggers: Stressful events, social situations, phobias, or sometimes no obvious trigger (spontaneous panic attack). 

Differentiation: Comparison Table 

If you are unsure about the cause of your chest pain, this comparison can help clarify the features. However, if there is any doubt, particularly if you have risk factors for heart disease, you should always treat it as a potential medical emergency. 

Feature	Angina	Heartburn (Reflux)	Anxiety
Pain Quality	Squeezing, pressure, heavy weight	Burning, hot	Sharp, stabbing, or tight
Location	Central chest, radiates to arm/jaw	Central chest, moves up to throat	Localised (point with finger) or general
Trigger	Exertion, cold, stress	Eating, lying down	Stress, panic, or spontaneous
Duration	Minutes (3–15 mins)	Hours	Seconds (stabs) or Minutes (panic)
Relieved By	Rest, GTN spray	Antacids, milk, standing up	Relaxation, time
Other Symptoms	Breathlessness, sweating, nausea	Acid taste, bloating, belching	Dizziness, tingling, palpitations

Conclusion 

Distinguishing between heartburn, anxiety, and angina requires paying close attention to the type of pain and what triggered it. Angina is usually a heavy pressure linked to exertion, heartburn is a burning sensation linked to food, and anxiety often involves sharp pains with palpitations. However, symptoms can overlap. 

If you experience sudden, severe chest pain that spreads to your arms, jaw, or back, or have difficulty breathing, call 999 immediately. Do not assume it is just anxiety or indigestion.
