Panic Attack vs Heart Attack: How to Tell the Difference
Panic attacks and heart attacks share symptoms, which is exactly why panic is so frightening. There are general differences, but when in doubt, get medical help.
Panic attacks and heart attacks share symptoms, which is exactly why panic is so frightening: chest discomfort, a racing heart, shortness of breath, sweating, and a sense of doom. There are some general differences, but they are not reliable enough to bet your life on. When in doubt, get medical help.
Read this first
If you have sudden chest pain and you are not sure what is happening, treat it as an emergency and call your local emergency number (911 in the US, 999 or 112 in the UK and Europe). You cannot reliably diagnose a heart attack on your own, and acting fast saves lives. It is always okay to get checked and be told it was anxiety. This article is for understanding the difference, not for ruling out a heart attack in the moment.
Patterns that often differ
These are tendencies, not guarantees.
Panic attack tends to involve: chest discomfort that is sharp, fleeting, or shifts when you breathe or press on it; a peak around 10 minutes, then a gradual ease; tingling in the hands or face, and a sense of unreality or detachment; a clear emotional trigger sometimes, or coming on at rest.
Heart attack tends to involve: pressure, squeezing, tightness, or heaviness in the chest, often lasting more than a few minutes or coming in waves; pain that may spread to the arm, jaw, neck, back, or shoulder; symptoms that come on or worsen with exertion; cold sweat, nausea, and shortness of breath, often without the tingling or unreality of panic.
Why you cannot rely on this alone
Symptoms overlap heavily, and heart attacks do not always look "classic," especially in women, older adults, and people with diabetes, who may have subtle or unusual signs. Risk factors matter too: a history of heart disease, high blood pressure, smoking, or being older raises the stakes. None of this can be sorted out reliably while it is happening, which is why the safe move when unsure is always to seek emergency care.
If you know it is panic
If you have a diagnosed panic pattern, you are calm enough to be confident, and the symptoms match your usual panic, you can ride it out: slow your breathing with a longer exhale, ground yourself, and remind yourself the peak passes in minutes. But this only applies once any cardiac concern has genuinely been ruled out, not as a way to talk yourself out of getting help.
No one has ever regretted getting chest pain checked and learning it was anxiety. The reverse is not true.

Frequently asked questions
How do I know if it is a panic attack or a heart attack? +
You often cannot be sure in the moment, because symptoms overlap. General differences exist, but if there is any doubt, especially with new or severe chest pain, call emergency services and get checked.
Can a panic attack feel exactly like a heart attack? +
Yes. Chest pain, racing heart, shortness of breath, and a sense of doom occur in both. This is why panic attacks so often send people to the emergency room, and why getting checked is reasonable.
What should I do if I am not sure? +
Call your local emergency number. Getting evaluated and learning it was anxiety is a good outcome, not a waste of anyone's time.
