Heart attack vs gas pain: differences in symptoms, tests and treatment
Written & medically reviewed by Dr. Sanjay Anbu, MBBS · Last reviewed
Medically reviewedGas or acidity pain is usually a burning or bloated feeling linked to meals that eases with burping or passing gas. Heart attack pain is more often a pressure, heaviness or squeezing in the chest that can spread to the arm, jaw or back, with sweating or breathlessness. The two can feel similar, especially in people with diabetes, women and older adults, so if in doubt, treat it as a heart attack and call 108 or 112.
Side-by-side comparison
| Feature | Heart attack | Gas pain |
|---|---|---|
| Cause | A blocked artery cuts off blood supply to part of the heart muscle | Trapped gas, indigestion or acid reflux (GERD) from the stomach |
| Typical symptoms | Pressure, heaviness or squeezing in the centre of the chest; may spread to left arm, jaw, neck or back; sweating, breathlessness, nausea, fear | Burning behind the breastbone, bloating, burping, sour taste; pain may move around the belly |
| Onset & timing | Sudden, at rest or on exertion; lasts more than a few minutes or comes and goes | Usually after meals, lying down or bending; eases with burping, passing gas or antacids |
| Key tests | ECG (quick, done first), troponin blood test, echocardiogram | Usually clinical; endoscopy if symptoms are frequent or worrying, after heart causes are ruled out |
| Treatment approach | Emergency: call 108/112, hospital treatment to reopen the artery as fast as possible | Smaller meals, avoiding late meals and triggers, weight loss, medicines to reduce acid as advised |
| Danger signs | Chest pain with sweating, breathlessness, fainting or pain spreading to arm/jaw | Vomiting blood, black stools, difficulty swallowing, weight loss |

How doctors tell them apart
- An ECG takes minutes and is the first step for any worrying chest pain.
- Troponin blood tests, sometimes repeated a few hours apart, show heart muscle damage.
- Doctors consider age, diabetes, blood pressure, smoking, cholesterol and family history.
- Relief with an antacid does NOT rule out a heart attack.
- Only after the heart is checked do doctors treat it as acidity.
See a doctor urgently if
- Chest pain, pressure or heaviness lasting more than a few minutes: call 108 or 112
- Chest discomfort with sweating, breathlessness, nausea or fainting
- Pain spreading to the arm, jaw, neck or back
- Sudden unexplained breathlessness or extreme tiredness, especially in diabetes or older age
- Vomiting blood or black, tarry stools
In an emergency, call your local emergency number (in India: 108 or 112).
Frequently asked questions
Can gas pain feel like a heart attack?
Yes, and a heart attack can feel like gas or acidity. That is why any new, severe or unusual chest pain should be checked with an ECG.
Where is heart attack pain felt?
Usually in the centre of the chest, sometimes spreading to the left or both arms, jaw, neck, back or upper belly. Some people, especially those with diabetes, feel only breathlessness or discomfort.
What should I do while waiting for help?
Call 108 or 112, stop all activity, sit down and stay calm. Do not drive yourself. Follow the advice of the emergency operator.
If an antacid helps, is it definitely acidity?
No. Relief after an antacid can be a coincidence. Do not use it to rule out a heart problem.
