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

Chest pain or discomfort is a primary sign of a heart attack. This symptom typically manifests as a feeling of pressure, squeezing, fullness, or pain in the center or left side of the chest. It may last for more than a few minutes or go away and come back. Recognizing this key indicator is critical because timely medical intervention can significantly improve outcomes for someone experiencing a heart attack.

While nausea and vomiting can also be associated with a heart attack, they are not as defining as chest pain or discomfort, which is more specifically recognized in clinical guidelines. Severe headache and high fever are not typical signs of cardiac events; they may indicate other medical issues but are not related to heart attacks. Understanding these distinctions can help individuals better recognize when to seek emergency care.
