What do high levels of low-density lipoprotein (LDL) indicate?

High levels of low-density lipoprotein (LDL) are associated with an increased risk of heart disease. LDL is often referred to as "bad cholesterol" because it can lead to the build-up of fatty deposits in the arteries, a condition known as atherosclerosis. This accumulation narrows the arteries, impeding blood flow and increasing the chance of cardiovascular events such as heart attacks and strokes.

Elevated LDL levels indicate a higher propensity for these adverse health outcomes. Conversely, low levels of LDL are generally associated with better heart health, as it reduces the likelihood of plaque formation in the arteries. Therefore, monitoring and managing LDL levels is crucial in cardiovascular risk assessment and management.
