Heart Attack vs. Panic Attack: How to Tell the Difference

Both conditions cause chest pain, shortness of breath, and intense fear — making them terrifyingly similar in the moment. However, their causes and implications are vastly different. A heart attack is a medical emergency caused by blocked blood flow to the heart. A panic attack is a surge of intense anxiety that triggers physical symptoms but does not damage the heart.

Key Differences at a Glance

Heart Attack
Crushing, squeezing pressure; feels like an elephant sitting on chest
Panic Attack

Pain Radiation
Heart Attack
Often radiates to left arm, jaw, back, or neck
Panic Attack
Usually stays in the chest area
Duration
Heart Attack
Persists and often worsens over minutes to hours
Panic Attack
Peaks within 10 minutes, usually resolves within 20-30 minutes
Trigger
Heart Attack
Exertion, but can occur at rest
Panic Attack
Stress, but can occur without obvious trigger
Age/Risk
Heart Attack
Rarely before 40; associated with cardiac risk factors
Panic Attack
Can occur at any age; more common in 20s-30s

Professional Diagnosis

Heart attack is diagnosed with ECG and cardiac biomarkers (troponin). Panic attack is diagnosed clinically after cardiac causes have been excluded.

Treatment for Heart Attack

Emergency treatment: aspirin, nitroglycerin, angioplasty/stenting, or thrombolytics. Long-term: cardiac medications and rehabilitation.

Treatment for Panic Attack

Acute: breathing techniques and grounding exercises. Long-term: CBT, SSRIs, and lifestyle management.

When to See a Doctor

IMPORTANT: If you are unsure whether you are having a heart attack or panic attack, ALWAYS call emergency services. It is far better to go to the ER for a panic attack than to stay home during a heart attack.
