Pets a Boon for the Human Heart, Cardiologists Say
American Heart Association cites stress-busting, dog-walking benefits of companion animals
By Robert Preidt
THURSDAY, May 9 (HealthDay News) -- That four-legged friend of yours may be more than a companion -- he also may be boosting your heart health, experts say.
An official statement released Thursday by the American Heart Association says there is evidence that having a pet, particularly a dog, may lower your risk of heart disease.
Cardiology specialists weren't all that surprised.
"Pets really might be man's best friend," said Barbara George, director of the Center for Cardiovascular Lifestyle Medicine at Winthrop-University Hospital in Mineola, N.Y.
"Studies have shown people who own pets, particularly dogs, have lower blood pressure, increased mood-related brain chemicals, better cholesterol numbers, lower weight and improved stress response," George said.
Members of the American Heart Association (AHA) committee that wrote the statement reviewed data from an array of relevant studies. They found that pet ownership appears to be associated with a reduction in heart disease risk factors such as high blood pressure, high blood cholesterol levels and obesity -- and improved survival among people with heart disease.
Dog ownership in particular may help reduce heart risk, the statement said. People with dogs may get more exercise because they take their dogs for walks. A study of more than 5,200 adults found that dog owners did more walking and physical activity than those who didn't own dogs, and that dog owners were 54 percent more likely to get the recommended level of physical activity.
"Walking your dog is a healthy chore; it is a great way to exercise without thinking about it," said Dr. Nieca Goldberg, clinical associate professor in the department of medicine at the Tisch Center for Women's Health at NYU Langone Medical Center in New York City. "Pet owners increase their physical activity simply by walking their dogs."
Pets can also have a positive effect on the body's reactions to stress, according to the AHA. George agreed, saying pets can be "a tool for weight loss, socialization, calming our nerves and easing anxiety and depression."
The AHA stressed, however, that the studies they reviewed cannot prove that owning a pet directly reduces heart disease risk.
