# Myocardial Infarction Treatment Summary Myocardial infarction treatment combines antiplatelet and anticoagulant medications with interventional procedures. **Aspirin** is a cornerstone first-line therapy that rapidly inhibits clot formation and significantly reduces mortality. **Percutaneous coronary intervention (PCI)** is the primary treatment when available, using stents to restore blood flow to blocked arteries. **Heparin** prevents new clots and complications during PCI procedures. **Metoprolol**, a beta-blocker, reduces heart workload and oxygen demand while improving outcomes and reducing mortality. **Nitroglycerin** provides symptom relief by improving blood flow and reducing cardiac strain, though without mortality benefit.
