Panic attack or heart attack? How to tell the difference

7 min read · Safety-first, evidence-based

Read this first. If you're having chest pain right now and you're not sure — treat it as a possible heart attack and call emergency services (911 in the US, or your local number). You can't safely diagnose your own heart, and it's always better to be checked and told “it was only panic.”

A pounding heart, chest tightness, shortness of breath, a cold sweat, a sense of doom — panic attacks and heart attacks share many symptoms, which is exactly why panic is so terrifying. Below are the typical differences. Use them to understand what's happening, not to rule out a medical emergency.

Typical differences

Important: these patterns are typical, not reliable. Heart attacks can be “atypical” — mild, or without classic pain — especially in women, people with diabetes, and older adults. No article can safely diagnose chest pain. When in doubt, get checked.

If it turns out to be panic

Once serious causes are ruled out, the chest tightness of anxiety is real but harmless — it comes from tense muscles and rapid breathing. What helps: name it (“this is panic, not my heart”), slow your exhale (in for 4, out for 6), and ground your attention in the room. The more your brain learns these sensations are safe, the less power they have.

Frequently asked

How can I tell a panic attack from a heart attack?

There are typical differences (see above), but they're not reliable enough to self-diagnose. If in doubt, treat it as a possible heart problem and seek emergency care.

When should I call emergency services?

Call immediately for chest pressure spreading to the arm/jaw/back, shortness of breath with the pain, cold sweat, nausea, fainting, symptoms from exertion, or a first-time episode you're unsure about. When in doubt, call.

Can anxiety cause chest pain?

Yes — from muscle tension and fast breathing. It's real and harmless in itself, but because it overlaps with cardiac symptoms, new or unexplained chest pain should be checked by a professional.
