sign of heart attack that always happens

Chest pain or discomfort is a common and classic sign of a heart attack that almost always occurs. This is often described as a feeling of pressure, tightness, or squeezing in the chest. Other possible symptoms that may accompany chest pain during a heart attack include shortness of breath, nausea, lightheadedness, and pain or discomfort in the arms, back, neck, jaw, or stomach. It is important to seek immediate medical attention if you experience any of these symptoms, as they could be indicative of a heart attack.
