Cardiac distress and nausea may be caused by simple lung infection or respiratory infection, or it may be due to acute myocardial infarction, especially in patients with inferior wall or right ventricular myocardial infarction, which is prone to heart discomfort accompanied by digestive symptoms such as nausea and vomiting. In addition to this, some menopausal women or patients with disorders of plant nerve function regulation are also prone to heart difficulties and nausea. There are also people with digestive system tumors who may experience similar conditions. Patients are advised to have an electrocardiogram, cardiac ultrasound and, if necessary, cardiac enzymes and coronary angiography to help further clarify whether acute myocardial infarction is currently occurring. In addition, it is recommended that patients can take sublingual compound salvia drops and, if necessary, add drugs that inhibit stomach acid, such as omeprazole, to help improve the symptoms of nausea.
