Scientist identify new form of harmful cholesterol

Tue, 31 May 2011

A new type of "ultra-bad" cholesterol that can increase the risk of heart disease has been identified by scientists.

Normal bad cholesterol, or low-density lipoprotein (LDL), is harmful as it sticks to arteries causing to the dangerous build up of fatty plaques.

However, the new form, called MGmin LDL, appears to be 'stickier' than normal LDL and is most often found in elderly people and those with Type 2 diabetes .

Scientists from the University of Warwick found that MGmin LDL is created by the addition of sugar groups to normal LDL - making LDL smaller and denser and more likely to stick to artery walls.

Dr Shannon Amoils, research advisor at the British Heart Foundation, which funded the study, said: "We've known for a long time that people with diabetes are at greater risk of heart attack and stroke .

"There is still more work to be done to untangle why this is the case, but this study is an important step in the right direction."
