What condition is characterized by hematochezia and pain after an MI?

• A. Ovarian torsion
• B. Appendicitis
• C. Ischemic colitis
• D. Pneumonia

Answer: (C)

The condition characterized by hematochezia (the passage of fresh blood through the anus) and abdominal pain following a myocardial infarction (MI) is ischemic colitis. This condition occurs when there is a reduction in blood flow to the colon, often as a result of atherosclerotic changes or embolic events that can occur post-MI due to compromised blood flow or arrhythmias that impact circulation. In the setting of an MI, the heart's ability to effectively pump blood can be diminished, leading to decreased perfusion of various organs, including the intestines. The colon is particularly vulnerable to ischemia because it has a watershed area that relies on collateral blood supply. When blood flow decreases, the colon can become ischemic, leading to inflammation and necrosis. This ischemic damage often presents with abdominal pain and can result in hematochezia due to mucosal injury and ulceration. The symptoms of abdominal pain and hematochezia serve as critical indicators of ischemic colitis and set it apart from the other conditions listed. For instance, ovarian torsion and appendicitis would typically present with localized abdominal pain, but not specifically with hematochezia. Pneumonia may cause pleuritic chest pain and respiratory symptoms but would not
