What is the role of statins after an acute coronary syndrome?

• A. Secondary prevention by lowering LDL and stabilizing plaques.
• B. Immediate relief of chest pain.
• C. Increasing LDL levels to worsen plaque stability.
• D. Reducing heart rate during an acute event.

Answer: (A)

Statins after an acute coronary syndrome are used for secondary prevention by lowering LDL cholesterol and stabilizing atherosclerotic plaques. Lowering LDL reduces the lipid content within vulnerable plaques and slows their progression, while the anti-inflammatory and plaque-stabilizing effects of statins make the fibrous cap less prone to rupture. Together, these actions decrease the risk of recurrent myocardial infarction, stroke, and death in patients who have already had an ACS.

They do not provide immediate relief of chest pain—that goal is met with antianginals and reperfusion therapies. They also do not raise LDL or acutely slow the heart rate during an acute event; their major benefit in this context is long-term risk reduction through lipid lowering and plaque stabilization.
