A County Monaghan health promotion professional who has been researching cardiovascular disease, urges women to "prioritise themselves" for their health.
In particular, Mr Treanor advises women to get to know the symptoms and risks of cardiovascular disease.
He said because research trials into the disease are usually conducted using male volunteers, the condition is under-recognised, under-researched, under-diagnosed and therefore, under-treated in women.
He also said that women should be aware that the symptoms of a heart attack are different for men than for women in that women may suffer from a long-term pain in their arm or even, jaw, rather than sharp chest pain.
JT Treanor said the good news is that 80 per cent of premature deaths through cardiovascular disease is avoided through lifestyle alone.
"From our polling and focus groups," the Emyvale researcher told Northern Sound, "we found that, in general, women don't realise the risk of cardiovascular disease. It's seen as a man's disease," he added
"One in four women in the country die of heart disease and we think that's something that is not spoken enough about in the public and people are not made aware of.
"Our goal is to see more women made aware of it so they can manage it," Mr Treanor said.
