What is the treatment for arteriosclerosis?

• A. ACE inhibitor
• B. Statin drugs
• C. Pacemaker
• D. Coronary artery bypass, stent, angioplasty

Answer: (D)

When arteries become narrowed or blocked by plaque, the goal is to restore blood flow to the heart muscle. The most direct and effective treatments for this are revascularization procedures. Coronary artery bypass grafting creates new routes for blood to reach the heart by bypassing the blocked sections. Angioplasty uses a balloon to widen the narrowed artery, and placing a stent helps keep the artery open after widening. These approaches directly address the blockage itself and improve blood flow, which is why they’re the best answer for treating arteriosclerosis when significant coronary blockages are present.

Medications like statins and ACE inhibitors are important for reducing risk factors—lowering cholesterol and blood pressure and slowing progression—but they don’t immediately restore blood flow through a narrowed artery. A pacemaker, on the other hand, helps regulate heart rhythm and does not treat arterial blockage.
