HDL Cholesterol

What is HDL Cholesterol?

High-density lipoprotein (HDL) performs reverse cholesterol transport — collecting excess cholesterol from arterial walls and peripheral tissues and returning it to the liver for excretion. HDL also has anti-inflammatory, antioxidant, and antithrombotic properties that protect the cardiovascular system beyond simple cholesterol removal.

What might a high or low HDL Cholesterol mean?

Low HDL is associated with higher cardiovascular risk. Interestingly, raising HDL with medication has not consistently reduced cardiovascular events, which suggests how well HDL functions may matter more than the amount alone.
