Heartburn Vs Heart Attack Symptoms: What’s the Difference?

Is that chest pain from something you ate—or something more serious? Every year, millions of Americans head to the ER fearing a heart attack, only to find out they’re dealing with severe heartburn. Still, chest pain should never be taken lightly.

Heartburn and heart attacks share similar symptoms, but they have very different causes—and potentially life-threatening consequences. Here’s how to tell them apart and when to seek help.

What Causes Heartburn?

Heartburn is a symptom of acid reflux or gastroesophageal reflux disease (GERD). It occurs when stomach acid flows up into the esophagus, irritating the lining and causing a burning sensation in the chest.

Heartburn can be triggered by:

• Large or spicy meals
• Lying down after eating
• Certain medications (like blood thinners or NSAIDs)

Heartburn Symptoms

If you're experiencing heartburn, you may notice:‍

• Burning pain behind the breastbone
• Pain that may rise toward the throat
• A bitter or acidic taste in the mouth
• Feeling of food or acid coming back up
• Pain that worsens when lying down or bending over
• Symptoms appearing after eating

Proton pump inhibitors (PPIs) are commonly prescribed or purchased over the counter to reduce stomach acid and prevent damage to the esophagus.

People who take daily aspirin—often recommended for heart disease prevention—may also be prescribed a PPI to protect the stomach lining from bleeding or ulcers.

What Causes a Heart Attack?

A heart attack occurs when blood flow to the heart is blocked, often due to a buildup of plaque in the arteries. This blockage causes tissue damage in the heart muscle and requires immediate medical attention.

Heart attacks can be triggered by:

• Physical exertion
• Stress
• Coronary artery disease
• Blood clots

Heart Attack Symptoms

Watch for these classic heart attack signs:

• Pressure, tightness, or squeezing in the center of the chest
• Pain radiating to the arms, neck, jaw, or shoulders
• Cold sweat, clammy skin
• Shortness of breath
• Nausea or vomiting
• Lightheadedness or fatigue
• Symptoms that appear with activity or stress

Medications like aspirin and clopidogrel (Plavix) are often prescribed to prevent clots and improve blood flow—especially for patients with stents.

Because these medications increase bleeding risk, doctors may also recommend an acid-reducing medication (like a PPI) to protect the stomach.

Quick Ways to Tell the Difference

Here are a few helpful clues:

When in Doubt, Call for Help

If you’re sweating, struggling to breathe, or feel pressure radiating through your chest—call 911 immediately. Heart attacks can be deadly without rapid treatment.

If the pain improves with antacids or burping, it’s likely heartburn—but you should still talk to your doctor, especially if symptoms recur often.
