Dogs Lower the Risk of Heart Disease

The American Heart Association issued a scientific statement yesterday that yes, owning a dog may protect us from heart disease. The statement was issued by an expert panel that was convened to look at alternative approaches to combat heart disease. They were prompted to look at the benefits of pet caring because of the growing number of medical studies linking pet ownership to better health.

Dr. Levine, a professor at the Baylor College of Medicine said, “there are plausible psychological, sociological and physiological reasons to believe that pet ownership might actually have a causal role in decreasing cardiovascular risk.” Dog ownership, partially because it compels people to walk their dogs and thereby getting more exercise, proved more beneficial than owning a cat. Richard Krasuski, a cardiologist at the Cleveland Clinic, thought this statement as more of an indictment of societal attitudes toward exercise. “Very few people are meeting their exercise goals,” he said. “In an ideal society, where people are actually listening to physician recommendations, you wouldn’t need pets to drag people outside.” (Feeling that walking my dogs is one of the greatest daily pleasures in my life, I would not quite agree that many of us actually consider our dogs as “dragging” us outside.)

“Several studies showed that dogs decreased the body’s reaction to stress, with a decrease in heart rate, blood pressure and adrenaline-like hormone release when a pet is present as opposed to when a pet is not present,” Dr. Levine said. Pet owners also tended to report greater amounts of physical activity, and modestly lower cholesterol and triglyceride levels. Some research showed that people who had pets of any kind were also more likely to survive heart attacks. All in all a definite win-win for us and our dogs.

The research also strongly suggested that there was a sharp contrast between those who walked their dogs themselves and those who did not.

Dr. Levine concludes by saying that they were not recommending that people adopt pets for any reason other than to give them a good home.

“If someone adopts a pet, but still sits on the couch and smokes and eats whatever they want and doesn’t control their blood pressure,” he said, “that’s not a prudent strategy to decrease their cardiovascular risk.”
