Your heart suddenly begins racing. You feel pain in your chest and you are short of breath.

Are you having a heart attack? Or could it be a panic attack?

Any of these symptoms can be extremely frightening."

Patricia Tung, MD, Division of Cardiovascular Medicine at Beth Israel Deaconess Medical Center

Although they share a number of similarities, the two conditions result from very different disease processes. Panic attacks arise when stress hormones trigger the body's "fight or flight" response, often resulting in racing heart, chest pain and shortness of breath.

In the case of a heart attack, a blockage in a coronary artery may result in the same symptoms. "Chest pain, rapid heartbeat and breathlessness may result when an insufficient amount of blood reaches the heart muscle," says Tung. (See "Symptoms" below.)

One of the key distinctions between the two is that a heart attack often develops during physical exertion, whereas a panic attack can occur at rest.

A heart attack is more likely to develop when the work load of the heart increases, for example while a person is shoveling snow or running up the stairs, especially in people who do not routinely engage in physical exertion.

Another difference is duration: Panic attacks tend to gradually subside and resolve on their own within about 20 minutes. A heart attack, however, will often continue and may worsen over time.

You should always seek immediate medical attention if there's any question, says Tung. In women, heart attack symptoms may be milder and could include unusual fatigue and chest discomfort rather than chest pain. It's important not to minimize symptoms, as the situation could quickly escalate. Never hesitate to call 911.

If symptoms are determined to be a panic attack, a number of treatment options are available, according to Aditi Nerurkar, MD, MPH, Medical Director of the Cheng-Tsui Integrated Health Center at BIDMC. These might include integrated therapies that focus on stress management and relaxation techniques such as meditation, acupuncture, yoga and tai chi.

The following are typical symptoms of heart attack and panic. Always contact your doctor or call 911 if you have any questions.
