Leg Vein Clots Boost Heart Attack, Stroke Risks
Patients with clots in the veins of the legs, known as deep vein
thrombosis (DVT), face higher risks for heart attack or stroke in
the year after a clot, according to a study in the Nov. 24 issue
of The Lancet.
These clots have been noted in passengers on long-haul flights
and have been dubbed "economy class syndrome," although
they do occur in other settings.
In the study, researchers at Aarhus University Hospital, Denmark,
tracked one-year outcomes for over 25,000 people with DVT,
almost 17,000 people with pulmonary embolism (clots that
travel to the lung), and close to 164,000 healthy controls.
They found that DVT boosted the 12-month risk of heart attack
and stroke by 60 and 119 percent, respectively, compared to
controls. Pulmonary embolism boosted the odds for heart attack
over the following year by more than two-and-a-half times
compared to controls, while nearly tripling a patent's risk of
stroke.
The increase in risk was roughly equivalent to that of
conventional cardiovascular risk factors such as diabetes and
smoking, the team noted. Copyright © 2007 ScoutNews LLC. All
