In elderly patients with diabetes presenting with myocardial infarction, which symptom may predominate rather than classic chest pain?

• A. Chest Pain Radiating to the Left Arm
• B. Epigastric or Abdominal Discomfort
• C. Shortness of Breath Only
• D. Syncope

Answer: (B)

Atypical presentations of myocardial infarction are common in elderly patients with diabetes because autonomic neuropathy can blunt the usual chest pain. As a result, what dominates the picture may be pain or discomfort felt in the upper abdomen or epigastric region rather than classic chest pain. Clinically, this means an elderly diabetic may present with epigastric or abdominal discomfort, sometimes accompanied by nausea, vomiting, or mild dyspnea, rather than the textbook chest pressure. While chest pain radiating to the left arm is a classic MI symptom, it is not as reliably dominant in this population due to neuropathy. Shortness of breath or syncope can occur, but they are less specific as the sole or primary symptom for MI in diabetics. Therefore, epigastric or abdominal discomfort best captures the atypical presentation described.
