Which of the following is NOT a major symptom of a heart attack?

The choice indicating that "pain/discomfort in legs" is not a major symptom of a heart attack is appropriate because the primary symptoms typically associated with heart attacks are more closely related to the chest, jaw, neck, back, and arms.

Major symptoms of a heart attack often include chest pain or discomfort, which is usually described as pressure, squeezing, fullness, or pain. Discomfort that radiates to the jaw, neck, back, or arms, as well as feelings of weakness, light-headedness, or fainting, are classic indicators that something might be wrong with the heart.

While leg pain can occur for a variety of reasons, it is not generally considered a direct or major symptom of a heart attack. In cases of heart-related conditions, symptoms are more focused around areas that may be receiving reduced blood flow as a result of the heart not functioning properly. This understanding is crucial for recognizing a heart attack early and seeking timely medical attention, thereby improving outcomes.
