Millions 'unaware of heart risk'

From The BBC: "Nearly four million people in the UK may be unaware they are at high risk of heart disease, research suggests. One in three of those most at risk over the next 10 years remain undiagnosed, the study estimates. An University of Oxford team screened more than 71,000 people aged over 18 across England, Wales and Scotland. Campaigners warned the study, published in the International Journal of Clinical Practice, showed too many people took their health for granted"
