Background
Acute coronary syndromes associated with mast cell activation (anaphylaxis or anaphylactoid reaction). Also known as Coronary hypersensitivity disorder.[1]
Clinical Features
- Stent thrombosis is the main manifestation of Kounis syndrome due to the mast cell infiltration of areas protected by drug-eluting stents<ref Kounis NG. Kounis syndrome should be considered the culprit cause of the most feared stent thrombosis. J Am Coll Cardiol. 2011;58:885.</ref>

Elevated Troponin
True Positive
False (Non-CAD) Positives
- Pericarditis
- Myocarditis
- PE
- CHF
- Sepsis
- Dissection
- Arrhythmias
- CVA
- SAH
- Burns
- Renal failure
- Assume true positive until proven otherwise
- ESRD
- 86% elevated predialysis in troponin-T
- 6% elevated predialysis in troponin-I
- no difference in post-MI troponin-I clearance rate in ESRD vs. normal GFR

Evaluation
Intensity of treatment should be based on ACS likelihood
