What is the effect of high levels of LDL cholesterol?

High levels of LDL cholesterol, commonly referred to as "bad" cholesterol, have a significant and detrimental effect on cardiovascular health. When LDL cholesterol levels are elevated, it can lead to an accumulation of cholesterol in the walls of blood vessels, a process that contributes to the formation of plaques. This buildup narrows the arteries, reducing blood flow and increasing the risk of atherosclerosis, which is the hardening and narrowing of the arteries due to plaque formation.

As a result of atherosclerosis, individuals face a greater risk of cardiovascular diseases, including coronary artery disease, heart attacks, and strokes. These conditions arise because reduced blood flow can cause damage to the heart muscle and other organs, compromising their function and leading to severe complications.

In contrast, options suggesting improved cardiovascular health, lowered blood pressure, or enhanced insulin sensitivity do not align with the well-established association between high LDL levels and increased cardiovascular risk. Elevated LDL cholesterol is not known to confer cardiovascular benefits or improve metabolic health; rather, it is linked to adverse outcomes.
