Intraoperative Myocardial Infarction
A 71yo male with HTN and GERD presented for ophthalmologic surgery for retinal detachment. Patient noted 2 months of 'reflux' symptoms during preoperative evaluation. Towards the end of the surgery the patient developed significant ST segment changes. They were treated intraoperatively with resolution of ST changes. From PACU the patient was taken for emergent cardiac catheterization which showed severe multivessel disease with ultimate successful PCI to LAD and LCX. Will discuss perioperative myocardial infarction and the differences in type 1 (primary coronary event) and type 2 (prolonged myocardial oxygen supply-demand imbalance) and an approach to intraoperative recognition and treatment.
