A 38-year-old woman has episodes of chest pain at dawn while asleep, with transient ST elevation during attacks, and angiography shows no significant blockages. Which drug does the nurse expect to be the mainstay?

1. A calcium channel blocker such as amlodipine
2. High-dose statin such as atorvastatin
3. An oral anticoagulant such as warfarin
4. A non-selective beta-blocker such as propranolol

Answer: A) A calcium channel blocker such as amlodipine. This is variant (Prinzmetal) angina from coronary spasm. Treatment is calcium channel blockers and nitrates. Non-selective beta-blockers can worsen spasm.
