1. Keep a low threshold for CT scanning in elderly patients with abdominal pain.
2. Cannot rule out acute mesenteric ischemia with labs alone.
3. Adequate resuscitation and IV antibiotics may prolong reversible ischemia time.
4. Keep AMI high in your differential diagnosis as mortality approaches 100% if missed.
5. CTA is much better than CT with IV and PO contrast (95% sensitivity vs. 83% sensitivity) if highly suspected.
