The study identified that those three individual factors -- smoking diabetes and high blood pressure -- are more likely to be linked to heart attacks in women showing the need for more awareness efforts targeted at women on the issue of heart diseases. The findings appeared in the journal BMJ. The rate of heart attacks in men remains three times higher than in women according to researchers at the University of Oxford. Nearly half a million British people enrolled in the UK Biobank were studied. They were between the ages of 40 and 69 and were recruited between 2006 and 2010.
