Cath Report:

RCA: normal

LCx: normal

LAD: acute plaque rupture and complete occlusion

Intervention: Stent placed to proximal LAD


  • Anteroseptal MI
    • ECG findings in V1-V4
      • ST segment elevation with Q wave formation in the precordial leads (V1-6) ± the high lateral leads (I and aVL)
      • Precordial leads
        • Septal leads = V1-2
        • Anterior leads = V3-4
        • Lateral leads = V5-6
    • Site of LAD occlusion (proximal versus distal) predicts both infarct size and prognosis.
    • Proximal LAD / LMCA occlusion has a significantly worse prognosis due to larger infarct size and more severe hemodynamic disturbance.
    • Lateral extension of an anterior, inferior or posterior MI indicates a larger territory of myocardium at risk with consequent worse prognosis.
