Certain type of cholesterol linked to heart trouble

Researchers say they have found the strongest evidence yet an often ignored form of cholesterol can cause heart attacks. It's a type of cholesterol called lipoprotein. According to a report in the Journal of the American Medical Association, people with high levels of lipoprotein were 2 to 3 times more likely to have a heart attack.

Lipoprotein is one of several forms of cholesterol where the levels are determined almost entirely by genetics.

Statins, taken by millions to cut the risk of heart attack and stroke risk, do not affect lipoprotein.

Researchers are hoping their finding will encourage the development of new cholesterol lowering drugs.
