100% proximal LAD occlusion

85% mid LAD lesion

2 stents placed


  • Anterior MI
    • Carries the worst prognosis of all infarct locations, mostly due to larger infarct size
    • ECG findings in V1-V3
      • 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.
