Which condition can a low HDL level lead to?

A low level of high-density lipoprotein (HDL), often referred to as "good" cholesterol, is directly associated with an increased risk of coronary artery disease. HDL cholesterol plays a crucial role in transporting cholesterol away from the arteries and back to the liver, where it can be reprocessed or eliminated from the body. A higher level of HDL is beneficial because it helps reduce the buildup of fatty deposits in the arteries, thus lowering the risk of heart-related issues.

When HDL levels are low, the protective effects against plaque buildup diminish, leading to a higher likelihood of developing atherosclerosis and coronary artery disease. This condition is characterized by the narrowing and hardening of the arteries, which can result in angina, heart attacks, or strokes.

This understanding highlights the importance of maintaining healthy HDL levels as part of a broader strategy for heart health.
