Inflammatory Response: release of IL-1 & TNF from macrophages & endothelial cells in response to tissue injury

  • Diagnosis of ACS

A similar table can be seen on p. 170, Table 7.5

*Key Features: Aside from the differences detected at clinical presentation,

  • UA & NSTEMI are distinguished based on the presence of serum biomarkers for myocardial necrosis

  • NSTEMI & STEMI are distinguished based on the detection of ST elevation on the ECG

1) Crescendo from previous chronic, stable angina 2) Angina at rest 3) New onset without a previous history of CAD

NSTEMI STEMI Prolonged, “crushing” chest pain that’s more severe, last longer, & radiates more widely than typical angina

No

Yes

Serum Biomarkers

Myocardial Infarction (MI)

Symptoms
