Acute coronary syndrome (main)

Background

ACS is three diseases involving the coronary arteries:

1. ST-Elevation Myocardial Infarction (STEMI) (30%)
2. Non ST-Elevation Myocardial Infarction (NSTEMI) (25%)
3. Unstable Angina (38%)

DDx

• Chest Pain (DDx)
• Troponin (DDx)
• Cocaine Chest Pain

Diagnosis

• ECG (Diagnosis)
  • ECG is normal in 8% of all confirmed MI's
• Cardiac Enzymes
• ACS - Risk Stratification
• ACS - Anatomical Correlation

Treatment

Intensity of Rx should be based on likelihood that sx are due to acute coronary thombosis

1. ST-Elevation Myocardial Infarction (STEMI)
2. Non ST-Elevation Myocardial Infarction (NSTEMI)
3. Unstable Angina

Disposition

Admit for all ACS

Prognosis

ACS - Stress Testing
