A common sign of a heart attack often includes symptoms like pale skin and difficulty breathing, which are indicative of the body not receiving enough oxygen due to reduced blood flow. When the heart muscle is damaged, it can lead to a lack of oxygen-rich blood being circulated throughout the body. This can result in a pale appearance, as well as shortness of breath due to the heart's impaired ability to pump effectively. These symptoms are significant and can alert individuals to seek immediate medical attention.

The other options mention symptoms that are not typically associated with a heart attack. A persistent cough is more often linked to respiratory issues rather than cardiac events. Loss of appetite may occur in various medical conditions but is not a classic sign of a heart attack. Lastly, a quickened heartbeat without pain may be a response to anxiety or other non-cardiac factors, but it does not specifically indicate a heart attack. Understanding the typical signs of a heart attack can be crucial for timely intervention and treatment.
