Cholesterol-like drug could protect your heart

A drug based on a form of cholesterol might be able to reduce the damage done by heart attacks. Working with experimental mice, scientists in Australia have found that so-called good cholesterol, also known as "HDL", if injected into the bloodstream shortly after a heart attack can prevent heart cells from dying. The experiments suggest that the HDL temporarily alters the way heart cells burn glucose, giving them more energy and improving their survival.
