33
Q

differentiate stable angina vs unstable angina vs NSTEMI vs STEMI

A
  1. stable angina = chest pain that resolves w/ rest
  2. unstable angina = chest pain that is new, is worsening, is non-responsive to meds, or occurs at rest + no changes on EKG + no elevation of cardiac enzymes
  3. NSTEMI = chest pain + no changes on EKG + elevation of cardiac enzymes
  4. STEMI = chest pain + changes on EKG + elevation of cardiac enzymes

treat wolf-parkinson white with? avoid?

A

treat w/ cardioversion and anti-arrhythmics like procainamide. avoid AV nodal blockers such as BB, CCB, digoxin, or adenosine b/c they can cause increased conductance through the accessory pathway
