Chest Pain Diagnosis and Management Algorithm
STEMI:
 - Hx: Pressure like CP, Radiation to arm/jaw, CAD risk factors
 - PEX: Non-reproducible, Non-pleuritic, N/V/diaphoresis
Aortic Dissection:
 - Hx: Sudden onset, severe, tearing CP, Risks: h/o Marfan, HTN, cocaine
 - PEX: New murmur, Pulse deficit, Focal neuro deficit, Limb ischemia
Pulmonary Embolism:
 - Hx: Sudden onset pleuritic CP, Dyspnea, PE risk factors
 - PEX: Dyspnea, Leg pain/swelling, Wells score
Pericarditis:
 - Hx: Pleuritic pain, Preceded by URI, underlying dz (SLE, uremia)
 - PEX: Positional: worse supine, improves on sitting up, Pericardial friction rub, Fever, ↑WBC
Boerhaave's:
 - Hx: Severe vomiting retrosternal CP, H/O recent instrumentation, EtOH, blunt trauma, caustic ingestion, HIV
 - PEX: crepitus?
Pneumothorax:
 - Hx: Acute pleuritic pain, Asthenic body, h/o trauma
 - PEX: Decreased/absent breath sounds, Dyspnea, H/O COPD, asthma, CF, PCP
