The benefit was highest for dog owners who lived alone."The most interesting part of this study was that people who lived alone actually seem to get the greatest benefit in both the heart attack group and the stroke group," said dog owner Dr. Martha Gulati, who is the editor-in-chief of CardioSmart.org, the American College of Cardiology's patient education platform."People who lived with a dog actually had less mortality than people living alone who didn't have a dog," said Gulati, who was not involved in either study.Heart attack survivors living alone who owned dogs had a 33% lower risk of death compared to people who did not own a dog. Stroke survivors living alone had a 27% reduced risk of death."We know that loneliness and social isolation are strong risk factors for premature death and our hypothesis was that the company of a pet can alleviate that," said study author Tove Fall, an associate professor of epidemiology at Uppsala University in Sweden."Single owners have to do all the dog walks and we know that physical activity is important in rehabilitation after a myocardial infarction or stroke," Fall added.Observational but significantBoth published studies were observational, meaning that researchers cannot prove that dog ownership was the direct cause of the increased life expectancy or the better health outcomes after heart attack and stroke; only a randomized clinical trial could answer those questions."Is it the dog or is it the behaviors?" Gulati asked. "Is it because you're exercising or is it because there is a difference in the type of person who would choose to have a dog versus somebody who would not? Are they healthier or wealthier? We don't know those things."The American Heart Association 1741
