Chest Pain Causes: What You Need to Know About Heart and Non-Heart Reasons

When your chest hurts, your brain screams heart attack. But not every sharp stab or dull ache means your heart is failing. Chest pain, a symptom that can stem from the heart, lungs, digestive system, or muscles. Also known as thoracic pain, it’s one of the most common reasons people rush to the ER—but up to half the cases aren’t cardiac at all. Knowing the difference can save you from panic, unnecessary tests, or worse—missing a real danger.

One of the biggest heart attack, a sudden blockage in a coronary artery that cuts off blood to part of the heart muscle symptoms is pressure, not pain. It feels like a heavy weight on your chest, often spreading to your arm, jaw, or back. It doesn’t go away with rest or antacids. Then there’s angina, a warning sign that your heart isn’t getting enough oxygen, often triggered by exercise or stress. It comes and goes, usually easing within minutes. If you’ve had it before, you’ll know the pattern. But if it’s new, worse, or lasts longer than 10 minutes, don’t wait—call for help.

Now, here’s what most people don’t realize: your stomach can mimic a heart attack. acid reflux, when stomach acid flows back into the esophagus causes a burning sensation right behind the breastbone. It often happens after eating, lying down, or bending over. You might even taste sour stuff in your throat. It’s not dangerous like a heart issue, but it’s painfully convincing. Then there’s muscle strain—lifting something wrong, coughing too hard, or even sleeping in a weird position can inflame ribs or chest muscles. That kind of pain sharpens when you breathe deeply or press on the spot.

Less common but serious? Lung problems like a pulmonary embolism or pneumonia. These often come with shortness of breath, fever, or coughing. Panic attacks can also trigger chest tightness, rapid heartbeat, and dizziness—but no physical damage to the heart. The key? Look for patterns. Does it happen every time you eat? Then it’s likely reflux. Does it flare up when you twist your torso? Probably muscle. But if it’s new, crushing, or paired with sweating, nausea, or fainting—don’t guess. Get checked.
