1. Oxygen — Used to maintain blood oxygenation as well as tissue and
cardiac O2 levels.
2. Aspirin — If administered when myocardial infarction is detected,
the antiplatelet properties of aspirin may reduce the overall size of
the infarction.
3. Thrombolytic therapy — If employed in the first 1 to 4 hours following
the onset of a myocardial infarction, these drugs may dissolve
clots in coronary blood vessels and re-establish blood flow.
4. Vasodilator drugs — Intravenous nitroglycerin can increase blood
flow to the myocardium and reduce myocardial work.
5.β-Blockers — Blunt the effect of catecholamine release on the myocardium,
reduce heart rate and myocardial work.
6. Pain management — Sublingual nitroglycerin, morphine if necessary
7. Antiarrhythmia drugs — To treat and prevent a number of potentially
life-threatening arrhythmias that might arise following a myocardialinfarction.
8. ACE inhibitors — Drugs that block activation of the renin–angiotensin
system and thus reduce the negative effects of vasoconstriction
and salt and water retention on the myocardium.
