Patients with heart disease may experience nausea. In common types of heart disease, such as coronary artery disease, acute coronary syndrome, and myocardial infarction, patients may experience severe chest pain, which often lasts for a long time, more than half an hour, accompanied by nausea, vomiting, cold sweats, decreased blood pressure, shock, and heart failure. For patients with coronary artery disease, chest pain can manifest as pain in the upper abdomen, while causing the onset of nausea and vomiting and other symptoms, requiring attention to differential diagnosis. In addition, for heart disease, such as heart failure caused by various types of organic heart disease, bruising of the body circulation may occur, in which bruising of the gastrointestinal tract may cause symptoms such as abdominal pain, abdominal distension, nausea and vomiting. In patients with heart disease, such as arrhythmias and atrial fibrillation, arterial thromboembolic events can occur, most commonly in strokes, in which symptoms such as dizziness, headache, hemiparesis, aphasia, nausea, and vomiting can occur.
