Which of the following is NOT a common symptom of a heart attack?

A bellyache is not commonly recognized as a symptom of a heart attack. The classic and widely acknowledged symptoms of a heart attack typically include chest pain, which can manifest as pressure, squeezing, or fullness; shortness of breath, which may occur with or without chest discomfort; and overwhelming anxiety, which can be a psychological response to the physical distress caused by the heart attack. These symptoms are associated with the physiological disruptions occurring in the body during a heart attack. In contrast, a bellyache is more associated with gastrointestinal issues and does not share a direct correlation with the heart or typical cardiac events. This distinction is important in recognizing the signs of a heart attack for prompt medical intervention.
