Final answer:
Excessive LDL cholesterol is associated with atherosclerosis and coronary heart disease, which can lead to heart attacks and strokes.
Step-by-step explanation:
Excessive LDL cholesterol is associated with several medical conditions, including atherosclerosis and coronary heart disease. When LDL cholesterol levels are too high, some cholesterol can be deposited in the arteries as plaques, causing inflammation and restricting blood flow. This can lead to a heart attack if blood flow to the heart is inadequate or a stroke if blood flow to the brain is insufficient.
