What is the main symptom of a heart attack?

The main symptom of a heart attack is chest pressure or pain. This symptom is often described as a feeling of heaviness, tightness, or discomfort in the chest area, and it may be accompanied by other sensations such as aching or fullness. This discomfort can radiate to other areas of the body, including the arms, back, neck, jaw, or stomach. Recognizing this symptom is crucial because it often serves as a warning sign that immediate medical attention is necessary.

While other symptoms like headache, fast heartbeat, or abdominal pain can occur during a heart attack, they are not the defining indicators. A headache may arise due to other factors, such as stress or tension, and while a fast heartbeat can occur as the body reacts to stress or pain, it is not specific to a heart attack. Abdominal pain can sometimes be experienced, but it is typically less common and often leads to confusion, as it may mimic gastrointestinal issues. Understanding the prominence of chest pressure or pain can aid in quicker recognition and response to such a critical medical emergency.
