In a patient presenting with chest pain, which finding would most strongly support myocardial infarction?

• A. Diaphoresis
• B. Rash
• C. Abdominal tenderness
• D. Polyuria

Answer: (A)

When a patient has chest pain, signs that reflect a sympathetic response to myocardial ischemia strongly push toward acute coronary syndrome. Diaphoresis, or heavy sweating, is a classic autonomic manifestation of myocardial infarction and helps differentiate a true cardiac cause from many non-cardiac chest pains. The other options don’t fit as well: a rash points to skin or allergic processes, abdominal tenderness suggests GI or other intra-abdominal problems, and polyuria is not a feature of acute coronary syndromes. So the presence of diaphoresis with chest pain most strongly supports an MI and should prompt urgent cardiac evaluation.
