Chest Wall Pain Pleuritic Pain Visceral Pain
Costosternal syndrome PE Typical exertional angina
Costochondritis Pneumonia Atypical (nonexertional) angina
Precordial catch syndrome Spontaneous pneumothorax Unstable angina

Xiphodynia Pleurisy Aortic dissection
Radicular syndromes   Pericarditis
Intercostal nerve syndromes   Esophageal reflux or spasm
Fibromyalgia   Esophageal rupture

Workup, phone orders
     Oxygen
     EKG
     Portable CXR
     ABG
     Labs: CBC, BMP, iCa, Mg, Phos, Enzymes, Coags

Workup (general)
     EKG--acute myocardial ischmia, infarction, pericarditis and tamponade have characteristic changes on EKG
     Cardiac enzymes (CK, CK-MB, troponin)--specific tests for myocardial tissue necrosis
     CXR--wide mediastinum suggests aortic dissection and may reveal other causes of chest pain, including pneumothorax and pneumonia
     TTE--can demonstrate segmental wall motion abnormalities in suspected acute MIs (infarction is unlikely in absence of wall motion abnormalities)
     TEE--highly specific and sensitive for aortic dissection, and can be done rapidly at the bedside
     CT-chest with IV contrast--another rapidly available diagnostic study that can rule out aortic dissection or pulmonary embolism
     Upper endoscopy--can document tissue damage characteristic of GERD. However, may be normal in up to 1/2 of symptomatic patients; esophageal probe (pH and manometry measurements) together with endoscopic visualization constitutes an effective diagnostic technique
     Cholesterol panel--can identify a critical risk factor for cardiovascular disease
