Heart Attack vs Panic Attack: Know the Difference

This is one of the hardest distinctions to make by symptoms alone — when in doubt, this is always treated as a medical emergency.

FeatureHeart AttackPanic Attack
Chest pain qualityPressure, squeezing, heavinessSharp or tight, can feel similar
Radiating painOften to arm, jaw, backLess typical, but can occur
OnsetCan build over minutes, with exertionSudden, can occur at rest
DurationPersists, doesn't fully resolve aloneUsually peaks and eases within 20-30 min
SweatingOften cold, clammy sweatCan occur, usually less profuse

Heart attack

Caused by blocked blood flow to the heart muscle — classic symptoms include chest pressure, pain radiating to the arm or jaw, shortness of breath, and cold sweat, though symptoms can be subtler in women and diabetics.

Panic attack

A surge of intense fear with real physical symptoms — a racing heart, chest tightness, and shortness of breath that can genuinely feel like a heart attack, but without the underlying blockage.

When to see a doctor

This one has a simple rule: if there's any real chest pain, especially with radiating pain, sweating, or shortness of breath — treat it as a possible heart attack and seek emergency care immediately. It is never safe to self-diagnose this as "just anxiety."

This comparison is for general awareness only and cannot replace a medical diagnosis. Many conditions share overlapping symptoms — a doctor can examine and test to tell them apart accurately.
