Which symptom is commonly associated with myocardial infarction (MI)?

• A. Diaphoresis alone
• B. Fever
• C. Cough
• D. Nausea and diaphoresis

Answer: (D)

Myocardial infarction often presents with autonomic symptoms such as sweating (diaphoresis) and nausea. The body’s stress response to ischemia drives sweating, and vagal irritation from the heart event can cause nausea. Seeing both symptoms together is a classic sign that raises suspicion for MI, more so than sweating alone or symptoms like fever or cough, which point to other conditions. In practice, when a patient has chest discomfort along with diaphoresis and nausea, it strengthens the likelihood of an MI and warrants urgent transport and monitoring.
