Which statement correctly describes radiation of chest pain during myocardial infarction?

• A. Chest pain can radiate to left arm, neck, jaw, or epigastric area
• B. Chest pain always worsens with rest
• C. Chest pain only in left arm
• D. Chest pain never accompanied by sweating

Answer: (A)

Radiation of chest pain in myocardial infarction happens because the heart’s ischemic signals travel along nerve pathways shared with areas like the left arm, neck, jaw, and upper abdomen. That’s why many people feel pressure or squeezing in the chest that can radiate to the left arm, the neck, the jaw, or the epigastric region. This radiation pattern is a typical feature of ischemic chest pain and helps distinguish it from other causes. Also, sweating is a common accompaniment due to sympathetic activation, so saying chest pain is never accompanied by sweating isn’t accurate. Additionally, MI pain isn’t reliably relieved by rest; unlike stable angina—where rest often eases symptoms— MI pain can occur at rest and may not improve with rest, and it isn’t limited to the left arm.
