Heartburn or heart attack: how to tell the difference

The honest answer is that you often cannot, and even doctors cannot without tests. Patterns help: heartburn is a burning feeling behind the breastbone that follows meals, worsens when you lie down or bend over, comes with a sour taste, and eases with antacids. A heart attack is more often pressure, squeezing, or fullness in the center or left of the chest, may spread to the arm, jaw, back, or stomach, and comes with shortness of breath, cold sweat, nausea, or lightheadedness. The traps run both ways: heart attacks can feel like burning, heartburn can cause severe pain, and antacids relieving the pain does not prove it was reflux. If there is any real doubt, treat it as a heart attack and call 911; the ER would rather rule it out than have you wait at home.

The CDC lists the major warning signs as: chest pain or discomfort in the center or left side of the chest that lasts more than a few minutes or comes and goes, often described as pressure, squeezing, fullness, or aching; pain or discomfort spreading to the jaw, neck, back, one or both arms, or shoulders; shortness of breath, with or without chest discomfort; and cold sweat, nausea, vomiting, or lightheadedness. Women are more likely than men to get the less famous signs: unusual fatigue, disturbed sleep, nausea, and back or jaw pain without dramatic chest pain. A heart attack does not always look like the movies. Any combination of these, especially lasting more than five minutes, means call 911 immediately rather than driving yourself or waiting it out.

Yes, and surprisingly intense pain at that. The esophagus runs directly behind the heart and shares nerve wiring with it, so acid irritation there produces pain in the same place, sometimes severe enough that people are certain they are having a heart attack. Reflux pain can also spread to the back, neck, and arms, mimicking cardiac pain further. The reverse trap exists too: heart attacks can produce a mild burning that feels exactly like ordinary heartburn, which is why some people take an antacid and wait at home through a real heart attack. Because neither side is safe to assume, new, severe, or unusual chest pain deserves medical evaluation rather than self-diagnosis, especially with risk factors like age over 40, smoking, diabetes, high blood pressure, or high cholesterol.

Call 911, do not drive yourself, when chest discomfort lasts more than 5 minutes or goes away and comes back; when it comes with shortness of breath, cold sweat, nausea, or lightheadedness; when pain spreads to the arm, jaw, back, or stomach; or when the feeling is pressure, squeezing, or fullness rather than a mild burn after a meal. Also call when chest pain comes with a sense of doom or is simply the worst you have ever felt, even without a textbook pattern. Emergency rooms rule out heart attacks quickly with an ECG and blood tests, and they would far rather send you home with a reflux diagnosis than have you arrive too late. Chewing a regular aspirin while waiting for the ambulance is commonly advised if you are not allergic and the 911 operator agrees.

For occasional heartburn: antacids neutralize acid within minutes; H2 blockers like famotidine work longer; and proton pump inhibitors like omeprazole are for frequent symptoms, taken daily for a course rather than as needed. The habits matter as much as the medicine: smaller meals, nothing within two to three hours of lying down, raising the head of the bed, and easing up on the common triggers, which are fatty or fried food, tomato, citrus, chocolate, peppermint, coffee, alcohol, and carbonated drinks. Tight waistbands, smoking, and carrying extra weight all push acid upward. Lying on your left side reduces nighttime reflux. If you need these measures most days for more than two weeks, that is no longer a home-care problem; it is time for a proper evaluation.

Heartburn becomes GERD, gastroesophageal reflux disease, when it happens frequently, usually defined as two or more times a week, or when it starts causing complications. The signs that move you from occasional heartburn to get-this-checked: symptoms several times a week despite avoiding triggers, needing daily antacids for weeks, trouble or pain when swallowing, a chronic cough or hoarse voice especially at night, food feeling stuck, or any unintended weight loss or vomiting. Untreated GERD can inflame and scar the esophagus over years, which is why persistent symptoms deserve a doctor rather than an ever-bigger supply of antacids. Most GERD is very treatable with daily medication and habit changes, and severe or stubborn cases have procedural options.
