Living alone doubles the risk of heart disease, suggests the largest prospective study so far to examine a possible link. But the same research also suggests that divorce may do the heart some good – but only for women.
Kirsten Nielsen of the Aarhus Sygehus University Hospital in Aarhus, Denmark, and colleagues used information from their national health database on people aged 30 to 69 living in Aarhus. They also examined these individuals’ health records from 2000 to 2002.
The team hoped to understand the risk factors that predispose people to a form of heart disease known as acute coronary syndrome, which includes heart attacks and sudden cardiac death.
Of over 138,000 people studied, 646 were diagnosed with acute coronary syndrome. Men above the age of 50, and women above 60, who lived alone were particularly at risk. Despite constituting just 8% of the whole study population, these groups accounted for more than 96% of all deaths within a month of a positive diagnosis, Nielsen notes.
