Points & Pearls Excerpt

  • Acute coronary syndromes (ACS) are currently stratified along a spectrum and include unstable angina, non-ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI).
  • Acute coronary occlusion (ACO) is most commonly caused by disruption of pre-existing atherosclerotic plaque within a coronary artery, leading to an inflammatory and thrombotic cascade.
  • When evaluating a patient with suspected ACS on ECG, there is a broad range of causes to consider. (See Table 1.)
  • Approximately 25%-30% of high-risk patients with ACO fail to meet standard STEMI criteria,2,3 which results in delays in catheterization laboratory activation and the potential benefits of revascularization.
