Nothing is wrong with me!

I am like no other!

Causes of Chest pains
Panjue et al JAMA 1998;280,14
Goals of CP assessment 1- Need to r/o serious causes of chest pain “ what is the chance that my patient will die due his underlying condition” 2- Need to refer for further testing i.e EST, V/Q scan, Angiogram etc.. 3- If cause of CP is not serious how can i help? eg. NSAIDS for MSL CP, PPI trial/GI consult for Reflux
Risk stratification 1. High risk AMI, High risk UA Lyse or cath 2. NSTEMI, LBBB, High risk UA Admit to CCU 3. Low risk UA, Non ischemic pain admit to ward or see as outpatient

Physical exam CVS exam: - JVP - Carotid bruit - Palpation of chest wall (where is the pain?) - Extra Heart sounds (S3 or 4) - Murmurs (eg, early diastolic, ) - Pericardial rub
Physical exam Chest exam: - Trachea - Breath sounds Abdomen: - Tenderness
InvestigationsECG: - NORMAL ECG DOES NOT ROLE OUT ISCHEMIA - Serial ECG’s - Always compare to an old ECG - ST ↑ (localized vs. Wide spread) - ST ↓ - T wave inversion (location and symmetry) or peaking
ECG (cont.) - Q waves (new) - New conduction defects (LBBB/RBBB) - Voltage/electrical alternans/Tachycardia - PE patterns (Q1 S3 T3), RBBB,
Other investigations (PRN) Depending on Hx/PE CBC CBC D-dimers D-dimers ABG’s ABG’s CXR CXR
Troponins I & T Most sensitive and specific cardiac markers Most sensitive and specific cardiac markers Rise 3-12hr after onset of CP Rise 3-12hr after onset of CP Peak I (24hr), T (12hr-2 days) Peak I (24hr), T (12hr-2 days) Return to normal 5-14 days Return to normal 5-14 days Has both diagnostic and prognostic values Has both diagnostic and prognostic values Sample at baseline and after 6-8hr Sample at baseline and after 6-8hr
