New York: A dog at home means longer life and better cardiovascular health, especially for heart attack and stroke survivors who live alone, according to a new study and a separate meta-analysis on the subject.
Prior studies have shown that dog ownership alleviates social isolation, improves physical activity and even lowers blood pressure.
"The two new studies provide good, quality data indicating dog ownership is associated with reduced cardiac and all-cause mortality," said Glenn N Levine, Chair of the writing group of the American Heart Association's scientific statement on pet ownership.
Researchers in this study compared the health outcomes of dog owners and non-owners after a heart attack or stroke using health data provided by the Swedish National Patient Register.
The patients studied were Swedish residents aged 40-85 who experienced a heart attack or an ischemic stroke from 2001-2012.
Compared to people who did not own a dog, researchers found that for dog owners, the risk of death for heart attack patients living alone after hospitalization was 33 percent lower, and 15 percent lower for those living with a partner or child.
The risk of death for stroke patients living alone after hospitalization was 27 per cent lower and 12 per cent lower for those living with a partner or child.
In the study, nearly 182,000 people were recorded to have had a heart attack, with almost 6 percent being dog owners, and nearly 155,000 people were recorded to have had an ischemic stroke, with almost 5 percent being dog owners. (IANS)
