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

Chest pain is a primary and well-recognized symptom of a heart attack. It often presents as a feeling of pressure, discomfort, or tightness in the chest. This pain can radiate to other areas of the body, including the arms, back, neck, jaw, or stomach. Recognizing chest pain as a sign of a potential heart attack is crucial for prompt medical attention, which can significantly increase the chances of survival and recovery.

While severe headaches, numbness in limbs, and high fever can indicate other medical conditions, they are not characteristic symptoms of a heart attack. Understanding these differences helps in responding appropriately to potential medical emergencies.
