The patient is a 73-year-old female with peripheral vascular disease, coronary artery disease, and systemic lupus erythematosus, who underwent mesenteric artery bypass surgery. She suffered from a pneumonia after surgery, causing acute hypoxic respiratory failure and septic shock. Due to shock, she developed acute renal failure. She was intubated, ventilated, and received continuous veno-venous hemodialysis for renal failure. ST elevation was first observed on telemetry and subsequently confirmed on electrocardiogram. Marked ST elevation is present in the anterior leads with reciprocal ST depression in the inferior leads. A prolonged QT interval is also present. What is the most likely diagnosis?
