Angina is one sentence of physiology: the myocardium is asking for more oxygen than the coronary arteries are delivering. Every drug in the acute coronary syndrome bundle attacks that sentence from one side or the other — it either lowers demand or raises supply. Tap each order to give it or withhold it, and watch which side of the ledger it actually moves.

Coronary arteries fill during diastole — that is why anything that slows the heart raises supply as well as lowering demand, and why tachycardia is an ischemic patient's enemy.

MONA is a memory aid, not a priority order.Aspirin and reperfusion save lives; nitrates relieve the pain; oxygen only if SpO₂ < 90%; morphine is last, not first.
