Heartburn vs Heart Attack: Know the Difference
Understanding the key differences between Heartburn and Heart Attack
Last updated:
⚡ Quick Summary
Heartburn causes a burning sensation in the chest/throat, usually after eating, and is relieved by antacids. A heart attack causes crushing/squeezing chest pressure that may radiate to the arm, jaw, or back, with shortness of breath and cold sweats. When in doubt, ALWAYS call 911 — it's better to be safe. Heart attacks require immediate emergency treatment.
Overview
Chest pain is one of the most common reasons people visit the emergency room, and for good reason — it can be difficult to tell the difference between heartburn and a heart attack. Both cause chest discomfort, but they have very different causes and vastly different levels of danger.
**Key Point:** When in doubt, always call 911. It is far better to be checked for heartburn at the ER than to ignore a heart attack at home. Time is critical during a heart attack — every minute without treatment means more heart muscle damage.
**Important Safety Note:** Women, diabetics, and elderly patients often have atypical heart attack symptoms. If something feels "off" or different from your usual heartburn, seek emergency care immediately.
Key Differences at a Glance
| Feature | Heartburn | Heart Attack |
|---|---|---|
| Cause | Stomach acid flowing back into esophagus | Blocked blood flow to the heart muscle |
| Pain Type | Burning sensation in chest/throat | Pressure, squeezing, heaviness, tightness |
| Pain Location | Behind the breastbone, rising toward throat | Center of chest, may radiate to arm, jaw, back, neck |
| Timing | Usually after eating, lying down, or bending over | Can happen anytime, often during exertion or stress |
| Duration | Minutes to hours; relieved by antacids | Usually lasts more than a few minutes; not relieved by antacids |
| Shortness of Breath | Rare | Common |
| Arm/Jaw Pain | No | Often radiates to left arm, jaw, neck, or back |
| Cold Sweat | No | Common (cold, clammy skin) |
| Severity | Uncomfortable but not dangerous | LIFE-THREATENING EMERGENCY |

Treatment Options
Heartburn Treatment
- ✓ Over-the-counter antacids (Tums, Rolaids) for quick relief
- ✓ H2 blockers (Pepcid, Zantac) to reduce acid
- ✓ Proton pump inhibitors (Prilosec, Nexium) for frequent heartburn
- ✓ Avoid trigger foods (spicy, fatty, acidic)
- ✓ Don't lie down for 2-3 hours after eating
- ✓ Elevate head of bed 6-8 inches
- ✓ Lose weight if overweight
- ✓ Quit smoking
Heart Attack Treatment
- ✓ CALL 911 IMMEDIATELY — do not drive yourself
- ✓ Chew an aspirin (325mg) while waiting for help
- ✓ Emergency angioplasty to open blocked artery
- ✓ Clot-dissolving medications (thrombolytics)

How Long Does It Last?
Heartburn
Usually lasts minutes to a few hours. Quickly relieved by antacids. Chronic GERD requires ongoing management.
Heart Attack
Symptoms typically last more than a few minutes and may come and go. Without treatment, heart muscle damage occurs within minutes. Recovery takes weeks to months.

Frequently Asked Questions
Frequently Asked Questions about Heartburn vs Heart Attack
Click on a question to see the answer.
Yes, severe heartburn can mimic heart attack symptoms. The chest pain from heartburn can be intense and spread to the throat and even the jaw. However, heartburn typically has a burning quality, occurs after eating, and responds to antacids. If you're unsure, always err on the side of caution and call 911.
Call 911 or go to the emergency room immediately. Doctors would much rather evaluate you for heartburn than have you ignore a heart attack. In the ER, they can quickly determine the cause with an EKG and blood tests. Never gamble with chest pain — early treatment for heart attacks saves lives.
Yes, though it's less common. Heart attacks can occur at any age, especially in people with risk factors like smoking, diabetes, high cholesterol, drug use (especially cocaine), or family history of early heart disease. About 1 in 5 heart attack patients are under 40. Don't dismiss chest pain just because of age.
Yes, women often have atypical symptoms. While chest pain is still common, women are more likely to experience shortness of breath, nausea/vomiting, back or jaw pain, and extreme fatigue — sometimes without classic chest pain. This is why women's heart attacks are more often missed or dismissed.
Not necessarily. While antacid relief suggests heartburn, some people report mild improvement during a heart attack due to placebo effect or coincidence. If chest pain returns, is accompanied by other symptoms (shortness of breath, arm pain, sweating), or feels different from your usual heartburn, seek emergency care regardless.
