What generally indicates a heart attack?

Persistent chest pain is widely recognized as a primary indicator of a heart attack. This pain can vary in intensity and may be accompanied by other symptoms such as radiation of pain to the arms, neck, jaw, or back. It is typically described as a feeling of pressure, squeezing, fullness, or pain in the center or left side of the chest. The nature of this chest discomfort, particularly if it lasts for more than a few minutes or goes away and comes back, is a critical sign that individuals should seek immediate medical attention, as it may indicate that the heart muscle is not receiving enough oxygen due to blocked blood flow.

While sudden fatigue and weakness can occur during a heart attack, they are less specific and can be attributed to various other conditions. Frequent headaches and shortness of breath only during exercise are also not direct indicators of a heart attack and could be linked to different health issues. Therefore, persistent chest pain stands out as a key symptom that warrants urgent evaluation.
