TUESDAY, Oct. 2 (HealthDay News) -- Postmenopausal women who've had at least one panic attack may be at greater risk for heart disease, stroke and even death, new research suggests.

The study found that older women with a history of panic attacks were four times more likely to have heart disease than women who hadn't had a panic attack.

"Women who reported at least one panic attack were at higher risk of having cardiovascular illness and death after an average of five years of follow-up. Even after controlling for other risk factors, a panic attack remained an independent risk factor on its own," said study author Dr. Jordan Smoller, an associate professor of psychiatry at Harvard Medical School.

Symptoms of a panic attack include a sudden feeling of fear, anxiety or extreme discomfort that's out of proportion to your current situation. Panic attacks may also be accompanied by a rapid or irregular heartbeat, sweating, hot flashes, chills, chest pain, difficulty breathing, shaking, dizziness and a feeling that you might die. About one in 10 postmenopausal women has had at least one panic attack, according to the study.

The research, published in the October issue of the Archives of General Psychiatry, included 3,369 postmenopausal women between the ages of 51 and 83. All of the women completed questionnaires about the occurrence of panic attacks in the previous six months. A full-blown panic attack was one in which sudden fear was accompanied by at least four other panic attack symptoms. A limited panic attack was one in which fear was accompanied by one to three additional symptoms.

After an average 5.3 years of follow-up, the researchers collected information on heart disease, stroke and death from any cause. The researchers also adjusted the data to account for other known cardiovascular disease risk factors, such as weight, alcohol use, hormone use, high cholesterol, high blood pressure, age, diabetes and smoking history.
