Interpretation

Very suspicious ECG for ACS

What happened next ?

The patient had serial ECG’s which showed dynamic T wave changes in the inferior leads and T wave amplitude antero-laterally. Serial troponins were positive. The patient underwent angiography which showed:

  • LMCA: Minor irregularities
  • LAD: Mid 99% single discrete lesion
  • Ostial 1st Diagonal: 90% single discrete lesion
  • CX: Irregularities
  • RCA: Irregularities

A stent was inserted to the LAD lesion and the ostial lesion was treated with balloon angioplasty. Echo showed normal systolic and valvular function. The patient was commenced on dual anti-platelet therapy (DAPT), statin, ACE and beta-blocker therapy.
