Which of the following is a symptom of a heart attack?

• A. Pain down the left arm
• B. Rash on skin
• C. Sneezing
• D. Headache

Answer: (A)

Pain down the left arm is a symptom of a heart attack because chest discomfort or pressure that radiates to the left arm is a recognized signal of cardiac distress. This referral of pain happens because the heart shares nerve pathways with the left arm, so signals can be felt there even though the heart is the source. The other options—rash on the skin, sneezing, and headache—are not typical signs of a heart attack; they point to skin conditions, allergies or infections, and non-cardiac causes, respectively. If someone experiences chest discomfort or any signs of possible heart attack, seek emergency care right away.
