Symptoms of heart attack and vomiting are usually associated with vagal nerve stimulation by necrotic myocardium, decreased cardiac output, and inadequate tissue perfusion. 1. Vagal nerve stimulation by necrotic myocardium: because the vagus nerve is stimulated by necrotic myocardium, etc. may lead to gastrointestinal symptoms such as nausea, vomiting, epigastric distension and pain. 2. Decreased cardiac output: The condition of infarction may also lead to a decrease in cardiac output, which in turn may lead to vomiting. 3. Inadequate tissue perfusion: Since heart attack may lead to insufficient blood supply to localized tissues or organs, some patients may show symptoms such as vomiting. If the diagnosis of heart attack is confirmed, early and standardized treatment is recommended to reduce the adverse effects of the disease.
