Characterization of Ischemic Colitis Associated with Myocardial Infarction: An Analysis of 23 Patients

Patients with both IC and MI present as a clinically distinct group from patients with either IC alone or MI alone. They have significantly more complications and worse in-hospital prognoses. They present with a dramatically lower MAP and a higher frequency of hypotension. This last finding suggests that the most common and most important mechanism for IC with MI may be hypotension from cardiogenic shock. Hypotension is the cardinal risk factor for generalized NOMI with acute mesenteric ischemia and may be an important risk factor for localized NOMI with IC. An APACHE II score greater than 15 may be a predictor of mortality from IC after MI.
