Which medication helps prevent progression of atherosclerosis?

• A. Nitroglycerin
• B. Beta-blocker
• C. Aspirin
• D. Statin

Answer: (D)

Lowering LDL cholesterol with a statin slows the progression of atherosclerosis. Atherosclerosis grows as cholesterol-rich debris accumulates in arterial walls and triggers inflammation; when LDL levels drop, there’s less substrate for plaque formation. Beyond lowering cholesterol, statins also reduce vascular inflammation and improve endothelial function, which helps stabilize plaques and can modestly reduce their size over time. This combination lowers the long-term risk of cardiovascular events by addressing the disease process itself. The other medications don’t target plaque progression in the same way. Nitroglycerin relieves angina through vasodilation but doesn’t alter plaque growth. Beta-blockers help control heart rate and blood pressure to reduce oxygen demand, not the underlying atherosclerotic process. Aspirin lowers the risk of clotting on an existing plaque but doesn’t slow or reverse plaque development.
