Which treatment is commonly used to lower cholesterol levels?

• A. Stent
• B. ACE inhibitor
• C. Pacemaker
• D. Statin drugs

Answer: (D)

Lowering cholesterol levels is commonly achieved with statin drugs. Statins work by blocking the liver’s production of cholesterol, which lowers the amount of cholesterol circulating in the blood. This reduction also prompts the liver to pull more LDL cholesterol from the bloodstream, further lowering blood levels. Because high LDL cholesterol is a major risk factor for atherosclerosis and heart disease, statins are a standard, first-line therapy for hypercholesterolemia and can reduce cardiovascular risk. The other options serve different purposes: a stent opens narrowed arteries, an ACE inhibitor helps control blood pressure, and a pacemaker regulates heart rhythm, but none directly lowers cholesterol.
