Podcast 783: LAD Occlusion & Troponin

Podcast 783: LAD Occlusion & Troponin

Contributor: Jared Scott, MD

Educational Pearls:

  • A study randomized 34 healthy patient to have their left anterior descending artery (LAD) occluded by balloon for 0, 15, 30, or 90 seconds
  • Subsequently, cardiac troponins (cTns) and Copeptin were measured every 15 minutes for 3 hours, then every 30 minutes for the next 3 hours
  • 5 conclusions were drawn:
    • Copeptin is not a useful marker of cardiac ischemia
    • cTn may be detected after only 30 seconds of ischemia
    • cTn may be detected in a little as 15 minutes after ischemic event
    • After only 90 seconds of ischemia, cTn levels met threshold for MI
    • Troponin I is a better marker than troponin T as it rises faster and reaches a higher peak
  • Patients very recent or very brief ischemic events may have elevated troponin in the ED
