    1. High Risk: Myocardial Infarction Protocol
    2. Moderate Risk: Myocardial Ischemia Protocol
  3. Management
    1. Heparin
      1. Preparations
        1. Weight based Heparin Nomogram
          1. Standard management in Acute Coronary Syndrome
        2. Low Molecular Weight Heparin
          1. As effective as Heparin in non-ST Elevation ACS
          2. Do NOT use if acute Angioplasty (PCI) is planned (discuss with cardiology first)
          3. Petersen (2004) JAMA 292:89-96 [PubMed]
      2. Continue Heparin until... (usually 24-48 hours):
        1. Definitive evaluation procedure or
        2. Revascularization performed
      3. Efficacy
        1. Heparin does not decrease overall mortality in ACS
        2. Heparin decreases the short-term (first 7-10 days) Myocardial Infarction rate by 3% (NNT 33)
          1. No difference in Myocardial Infarction rate at 30, 60 and 90 days
          2. Heparin appears to delay Myocardial Infarction to the longterm in these 3% of patients
        3. Low Molecular Weight Heparin and Unfractionated Heparin both have a 4% risk of major bleeding
          1. Major bleeding includes serious complications (Intracranial Hemorrhage, transfusion required)

          2. Step 2: Metoprolol Succinate (Toprol XL) 50-100 mg orally once daily
      5. Carvedilol (Coreg)
        1. Start: 3.125 mg orally twice daily

        3. Longterm plan to titrate up to 25 mg orally twice daily
    4. ACE Inhibitor
      1. Start when stable or 6 hours after event (within first 24 hours) if not contraindicated
      2. Specific Indications
        1. Heart Failure (esp. ejection fraction <40%)
        2. Anterior STEMI
      3. Lisinopril 2.5 to 5 mg orally daily (titrating up to 10 mg orally daily)

      4. Start at loading doses prior to PCI and continue at maintenance dose for 12 months after event or stenting
        1. Example: Load Plavix at 300-600 mg and then give 75 mg daily

Myocardial Infarction (C0027051)

Definition (MEDLINEPLUS)

Each year over a million people in the U.S. have a heart attack. About half of them die. Many people have permanent heart damage or die because they don't get help immediately. It's important to know the symptoms of a heart attack and call 9-1-1 if someone is having them. Those symptoms include

  • Chest discomfort - pressure, squeezing, or pain
  • Shortness of breath
  • Discomfort in the upper body - arms, shoulder, neck, back
  • Nausea, vomiting, dizziness, lightheadedness, sweating

These symptoms can sometimes be different in women.

What exactly is a heart attack? Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart. A blockage that is not treated within a few hours causes the affected heart muscle to die.
