What are the signs of a heart attack?

The signs of a heart attack primarily include chest pain, shortness of breath, and discomfort. These symptoms are crucial for identification during a potential cardiac event. Chest pain typically feels like pressure, squeezing, fullness, or pain in the center or left side of the chest and may last for more than a few minutes or go away and come back. Shortness of breath can occur with or without chest discomfort and may present as an uncomfortable feeling of being unable to catch one's breath.

These symptoms indicate insufficient blood flow to the heart muscle, typically caused by blockages in the coronary arteries. Identifying these signs swiftly is vital, as timely intervention can significantly affect outcomes in a cardiac emergency.

The other options present symptoms that are not typical for heart attacks. Severe head pain and dizziness may point to other medical conditions, while loss of consciousness and paralysis suggest neurological issues rather than a heart event. A high fever combined with a rapid heart rate might indicate an infectious process, not a heart attack. Recognizing the correct signs associated with a heart attack is essential for appropriate and timely medical response.
