Oct. 1, 2007 -- Older women who experience panic attacks appear to have an
increased risk for having heart attacks or heart-related death, new research
Postmenopausal women in the study who reported at least one full-blown panic
attack within six months of being interviewed were four times as likely as
other older women to have a heart attack or related death
over the next five years.
They were three times as likely to have either a heart attack, heart-related
death, or stroke, and nearly twice as
likely to die from any cause.
Earlier studies have implicated depression as a risk factor for
heart disease, but the new
research is the first to suggest a direct link between anxiety-related panic attacks
and heart attack and stroke risk.
Harvard Medical School associate professor of psychiatry Jordan W. Smoller,
MD, ScD, who led the study team, says more research is needed to confirm the
"There is not a lot of previous evidence suggesting that panic attacks
are in themselves dangerous (in terms of heart risk)," he tells WebMD.
"Our study does not resolve the question. But it does suggest that older
women with a recent history of panic attacks may warrant closer scrutiny for
Panic Attacks and Heart Attacks
The study included 3,369 healthy postmenopausal women participating in the
larger ongoing Women's Health Initiative (WHI) trial examining risk factors for
heart disease and other health outcomes among older women.
When they entered the study between 1997 and 2000, the women, whose average
age was 66, were asked if they had recently experienced a panic attack. They
were then followed for an average of 5.3 years.
At enrollment, one out of 10 women reported having had a full-blown panic
attack within six months.
After adjusting for the impact of other established cardiovascular risk
factors, a recent panic attack was associated with a fourfold increased risk of
heart attack or heart-related death and a twofold increase in death from any

of General Psychiatry. The
