Men are more likely to die from hearth failure than women.
This was the key finding of a large study by the European Society of Cardiology of more than 40,000 people.
If found that women with chronic heart failure survive for longer than men with the same condition, a fact that has been missed as previous studies have been male-dominated.
In the three years following heart failure, 25.3 per cent of women and 25.7 per cent of men died.
But when adjusted for age, the results showed that men were 31 per cent more likely to die three years after heart failure than women.
"The female heart appears to respond to injury differently from the male heart," said author Dr Manuel Martinez-Selles from the Gregorio Maranon University Hospital in Madrid.
"Some of these advantages could be related to pregnancy and to sex-specific differences in gene expression."
Researchers at Emory University also found that marriage has a significant impact on someone's survival after heart surgery.
Married adults are more than three times more likely than their single counterparts to survive the next three months.
