Which medications are commonly prescribed after acute coronary syndrome for secondary prevention?

• A. Antiplatelets, statins, nitrates, and beta-blockers
• B. Diuretics and ACE inhibitors only
• C. Antibiotics
• D. No medications required

Answer: (C)

The main idea is preventing another heart attack after an ACS by addressing thrombosis, lipid management, and cardiac remodeling. The cornerstone therapy typically includes antiplatelet treatment to keep the arteries open (such as aspirin combined with a second agent after PCI), a high‑intensity statin to lower LDL and stabilize plaques, and medications that reduce myocardial oxygen demand and protect the heart’s structure—beta-blockers and an ACE inhibitor or ARB—when not contraindicated. Nitrates are often used for ongoing angina relief, while diuretics are added if there’s heart failure or fluid overload. Antibiotics have no role in preventing recurrent ACS, since there isn’t an infection to treat in this context. So the best approach combines antiplatelets, statins, beta-blockers, and ACE inhibitors or ARBs for most patients, with nitrates for symptom control as needed.
