Findings published in the Dec. 11 online issue of the American Journal of Hypertension show that a 'too-fast' heartbeat in early adulthood could herald cardiovascular problems later in life.

The study of 614 residents of a rural farming community in southwestern Japan found that a heart rate greater than 80 beats a minute during a first examination in 1979 predicted the development of obesity and type 2 diabetes, which contribute to heart problems.

"If someone has a consistently fast heart rate, it is because of increased input from the sympathetic part of the nervous system because the body is preparing to respond to stress," says Mercedes Carnethon, assistant professor of preventive medicine at Northwestern University's Feinberg School of Medicine. . "There is an increase in levels of blood glucose — essentially because the body is storing energy to prepare for fight or flight, so that predisposes to type 2 diabetes."
