What is a common outcome of maintaining high LDL cholesterol levels?

Maintaining high LDL (low-density lipoprotein) cholesterol levels is associated with a greater risk of heart disease. LDL is often referred to as "bad" cholesterol because elevated levels can lead to the buildup of plaque in the arteries, which narrows them and makes it more difficult for blood to flow properly. This process, known as atherosclerosis, can eventually result in serious cardiovascular problems, including heart attacks and strokes. Therefore, managing cholesterol levels, particularly keeping LDL low, is crucial for reducing heart disease risk and promoting overall cardiovascular health.

The other options do not accurately reflect the implications of high LDL cholesterol levels. For instance, high LDL is not linked to increased energy; in fact, it can have the opposite effect on overall health. Lower triglycerides is a beneficial outcome typically associated with healthy lifestyle choices and managing cholesterol, while improved cardiovascular fitness is influenced by regular physical activity and nutrition rather than merely by the levels of LDL cholesterol.
