What is the primary purpose of statins in relation to heart disease?

The primary purpose of statins in relation to heart disease is to lower cholesterol levels. Statins are a class of medications that inhibit the enzyme HMG-CoA reductase, which plays a central role in the production of cholesterol in the liver. By reducing cholesterol synthesis, statins effectively lower the levels of low-density lipoprotein (LDL) cholesterol in the bloodstream. High levels of LDL cholesterol are a significant risk factor for the development of atherosclerosis, a condition characterized by the buildup of fats, cholesterol, and other substances in and on the artery walls, which can lead to heart disease, heart attacks, and strokes.

In addition to lowering LDL cholesterol, statins have been shown to have other beneficial effects on cardiovascular health, such as stabilizing plaques in blood vessels and possessing anti-inflammatory properties. Their primary role, however, rests on their ability to reduce cholesterol levels, thereby lowering the risk of cardiovascular events and improving overall heart health.
