TUESDAY, Nov. 16 (HealthDay News) --The more weight a person
gains, the greater the risk that individual will develop the
narrowing of heart arteries and reduced blood flow to the heart
that can lead to a heart attack, a new Danish study indicates.
The research team found that for every 8.8 pound increase in the
weight portion of an individual's body-mass index (BMI), that
person's risk for developing ischemic heart disease rose by more
than 50 percent.
The authors base their observation on combined data from three
studies that tracked BMI and/or heart disease among approximately
81,000 Danish men and women.
The authors concluded that their findings are evidence of a
direct cause-and-effect between elevated BMI and raised heart
Researchers also analyzed specific gene variants thought to play
a role in increased BMI or a predisposition for both higher BMI
levels and heart disease. They concluded that gene variants also
play a role in the development of both higher BMIs and increased
risk of ischemic heart disease.
Dr. Borge Nordestgaard, of the University of Copenhagen in
Herlev, is slated to present his team's findings Tuesday at the
American Heart Association annual meeting in Chicago.
