Which of the following is not among the listed procedures to treat plaque?

• A. Pacemaker implantation
• B. CABG
• C. Angioplasty
• D. Stenting

Answer: (A)

Treating plaque in the coronary arteries means restoring blood flow by opening or bypassing blocked segments. Angioplasty expands the narrowed artery, often with a stent to keep it open. CABG creates a new route for blood around the blocked area. Pacemaker implantation, however, is used to regulate heart rhythm and does not remove plaque or directly improve blood flow through a blocked coronary artery. So it’s not a procedure used to treat plaque. (In some cases a pacemaker may be needed for rhythm problems, but that’s separate from addressing atherosclerotic blockages.)
