Study: Even a little flab raises heart risk

WASHINGTON - Even a little extra weight can raise the risk of heart failure, according to a Brigham and Women's study published yesterday that calculated the heart hazards of being pudgy but not obese.

It comes as little surprise that obesity makes a person much more apt to get heart failure, a deadly condition in which the heart is unable to pump enough blood throughout the body.

But researchers who tracked the health of 21,094 US male doctors for two decades found that even those who were only modestly overweight had a higher risk - and it grew along with the amount of extra weight.

In men who are 5 feet 10 inches tall, for every seven pounds of excess body weight, their risk of heart failure rose on average by 11 percent over the next 20 years, the researchers wrote in the journal Circulation.

"The lean and active group had the lowest risk," said Satish Kenchaiah of Brigham and Women's Hospital in Boston.

The average age of the men at the outset of the study was 53. During the study, 1,109 of them developed heart failure.

Overall, the risk of heart failure increased by 180 percent in men who met the definition of obesity according to their body mass index (BMI of 30 and higher), and by 49 percent in men who met the definition of overweight (a BMI of 25 to 30).

Heart failure contributes to 300,000 American deaths a year.
