This occurs because the heart and gastrointestinal (GI) tract share some of the same nerve pathways, particularly those related to the vagus nerve. As a result, when the heart is under distress, such as during an MI, signals may be sent that can lead to gastric upset, resulting in nausea and potentially vomiting.

The presence of nausea and vomiting may indicate a more severe or extensive heart attack and can be particularly distressing for the patient.
