What signs might indicate that someone is experiencing a heart attack?

Chest discomfort and nausea are well-documented signs of a heart attack. When someone is experiencing a heart attack, they may feel pressure, squeezing, fullness, or pain in the center or left side of the chest. This discomfort can also radiate to the shoulders, neck, arms, back, teeth, or jaw. Nausea, often accompanied by sweating or shortness of breath, can occur due to the body’s stress response to a heart attack. Recognizing these symptoms is crucial for prompt medical intervention, which can significantly improve outcomes for the individual experiencing a heart attack.

The other options do not present classic signs of a heart attack. Continuous laughter and energy are not associated with heart distress; frequently yawning and being tired may indicate fatigue or sleep deprivation rather than a cardiac issue; and excessive perspiration alone, without other accompanying symptoms, is not specific enough to indicate a heart attack, as it can occur for many reasons unrelated to cardiac events.
