Heartburn Or Heart Attack? How To Tell And When To Call 911

Chest discomfort is one of the most anxiety-producing symptoms people experience. Is it heartburn after a meal, or could it be something more serious like a heart attack? The hard part is that heartburn and heart attack symptoms can overlap, and many people delay care because they assume it is indigestion. Heart attacks do not always feel sudden or dramatic. Some feel mild, vague, or similar to reflux. Knowing the difference is helpful. Knowing when not to guess is even more important. This guide compares reflux patterns with cardiac red flags and gives simple “home vs urgent care vs 911” guidance. It is designed to support decision-making without minimizing risk. Important: If you have new, severe, or worsening chest pain, or you are unsure what is causing it, call 911

Why Heartburn And Heart Attack Symptoms Can Feel Similar

Heartburn happens when stomach acid moves up into the esophagus and irritates its lining. The esophagus sits close to the heart, so discomfort from reflux can feel like chest pain. Heart-related pain can also feel like pressure, tightness, burning, fullness, or indigestion. That overlap is why clinicians emphasize a simple rule: If you are not sure, get evaluated.

Common Signs Of Heartburn Or Acid Reflux

Heartburn symptoms are often linked to meals and body position. Common clues include:

• • Burning sensation behind the breastbone

• • Symptoms that start after eating, especially after a large, spicy, or fatty meal

• • Discomfort that worsens when you lie down or bend forward

• • Sour or acidic taste in the mouth

• • Relief with antacids in some cases

Some people have occasional heartburn. Others have frequent symptoms related to GERD. If you are dealing with recurring reflux or indigestion, you can learn more about evaluation and treatment at iCare here: https://www.icare-er.com/heartburn-treatment-indegestion/ Important note: Feeling better after an antacid does not rule out a heart problem. If symptoms are new, unusual, or concerning, do not rely on self-treatment as your only decision point.

Warning Signs That May Indicate A Heart Attack

Call 911 immediately if chest discomfort is accompanied by any of the following:

• • Pressure, squeezing, heaviness, or tightness in the chest

• • Pain spreading to the arm, shoulder, back, neck, or jaw

• • Shortness of breath

• • Cold sweat

• • Nausea or vomiting

• • Lightheadedness or fainting

• • A sudden feeling that something is seriously wrong

Symptoms can happen at rest or with activity. They may come on suddenly or build gradually. If you think you may be having a heart attack, calling 911 is the safest option.

Heart Attack Symptoms In Women

Women can have classic chest pressure, but they are also more likely to experience symptoms that feel less “typical.” That can delay care. Symptoms may include:

• • Unusual fatigue or weakness

• • Shortness of breath

• • Nausea or indigestion-like discomfort

• • Upper back, shoulder, or arm pain

• • Dizziness

If something feels different from your usual heartburn pattern, it is worth getting checked. According to the American Heart Association, women may experience symptoms such as nausea, fatigue, and shortness of breath that are often mistaken for indigestion.

Heartburn Vs Heart Attack Key Differences

No checklist is perfect, but these patterns can help you think more clearly in the moment.

More Consistent With Heartburn Or Reflux

• • Burning sensation

• • Starts after eating

• • Worse when lying down

• • Worse when bending forward

• • Associated with sour taste or regurgitation

• • Similar to your past reflux symptoms

More Concerning For A Heart Attack

• • Pressure, squeezing, tightness, or fullness

• • Shortness of breath

• • Sweating, nausea, or dizziness

• • Pain that spreads to the jaw, arm, shoulder, back, or neck

• • Symptoms triggered by exertion

• • Symptoms that feel new or different than usual

If your symptoms do not clearly fit the reflux pattern, do not try to “wait it out.”

Chest Pain After Eating When It Is Not Just Indigestion

Chest pain after eating is commonly linked to reflux, but it should not be automatically dismissed. Heart-related conditions can also present around meal times, especially if symptoms include pressure, shortness of breath, sweating, or radiation to the arm or jaw. Get evaluated if chest pain after eating is:

• • New or worsening

• • Happening more often

• • Lasting longer than usual

• • Paired with shortness of breath, sweating, dizziness, or faintness

• • Spreading to the arm, jaw, back, or neck

• • Not responding to typical measures that used to help

Home Vs Urgent Care Vs 911 What To Do Next

You May Monitor At Home If All Of These Are True

• • Symptoms match your typical heartburn pattern

• • Discomfort is mild

• • Symptoms improve with posture changes

• • You do not have shortness of breath, sweating, faintness, or radiating pain

• • You feel generally well otherwise

If symptoms return frequently, interrupt sleep, worsen, or become more intense, it is time for medical evaluation.

---

Consider Urgent Care If Any Of These Apply

• • You suspect reflux, but symptoms are new or happening more often

• • Chest discomfort is mild but persistent

• • You want guidance on GERD, gastritis, medication effects, or dehydration

• • You are unsure what is causing symptoms, but you do not have severe red flags

Many people come in simply because they want clarity. That is a reasonable reason to be evaluated. CTA: If you are experiencing recurring heartburn or indigestion symptoms, explore care options here: https://www.icare-er.com/heartburn-treatment-indegestion/

Call 911 Immediately If Any Of These Apply

• • Chest pain is severe, crushing, or worsening

• • You have shortness of breath, fainting, confusion, or a cold sweat

• • Pain spreads to the arm, jaw, neck, or back

• • Symptoms occur with exertion

• • You have known heart disease or significant risk factors and symptoms feel unusual

If you are truly unsure and symptoms feel concerning, choose emergency help.

Why Getting Evaluated Early Matters

Chest pain can have many causes, ranging from reflux to heart emergencies. The risk is not just what the symptom could be, but how quickly a dangerous cause needs treatment. Waiting too long can lead to worse outcomes if the cause is cardiac. Many people who later learn they had a heart event report delaying care because they assumed it was “just heartburn.” Early evaluation is not overreacting. It is a safety decision.
