Good cholesterol too may raise heart attack risk
Good cholesterol, which helps battle heart diseases, may sometimes raise the risk of heart attacks, says a new study.
Cholesterol is a waxy, fat-like substance that occurs naturally in all parts of the body. There are two types of cholesterols - high-density lipoprotein (HDL) and low-density lipoprotein (LDL). HDL cholesterol is known as good cholesterol, because high levels of HDL seem to protect against heart attacks.
High levels of LDL cholesterol or bad cholesterol in the blood can, however, increase the risk of heart diseases. If it increases in the blood, it can stick to the walls of arteries.
The new study has shown HDL is not always good for the heart. If it exists in defective forms, it can increase the risk of a heart attack.
