Lowering cholesterol protects your heart and brain, regardless of your age

High or abnormal cholesterol levels, inflammation, and endothelial dysfunction play a key role in atherosclerosis and plaque buildup, the most common cause of heart attacks and strokes. (Endothelial dysfunction refers to impaired functioning of the inner lining of blood vessels on the heart’s surface. It results in these vessels inappropriately narrowing instead of widening, which limits blood flow.) There are many different types of cholesterol, including high density lipoprotein (HDL, or good, cholesterol); triglycerides (a byproduct of excess calories consumed, which are stored as fat); and low-density lipoprotein (LDL, or bad cholesterol). It’s well established that lowering LDL cholesterol, sometimes regardless of whether or not you have high cholesterol, improves cardiovascular outcomes. But do older adults reap the same benefits from lowering cholesterol, and do they face additional risks? Lowering LDL reduces cardiovascular risk Studies have consistently shown that lowering LDL cholesterol reduces the risk of cardiovascular death, heart attacks, strokes, and the need for cardiac catheterizations or bypass surgeries. This has been shown in those with established coronary artery disease, as well as in high-risk patients without coronary artery disease. Lifestyle changes can decrease cholesterol numbers by about 5% to 10%, while cholesterol-lowering medication can decrease LDL cholesterol by 50% or more. Therefore, while lifestyle modifications like a heart-healthy d...
