Patients with myocardial ischemia who experience nausea and vomiting need to first determine if the symptoms are related to myocardial ischemia. If the symptoms of nausea and vomiting are caused by myocardial ischemia, you can choose general treatment, medication and surgery to relieve the symptoms. 1. General treatment: Limit physical activity, bed rest, so as to reduce the load on the heart. At the same time, dietary intake of sodium should be reduced, which can effectively alleviate the above discomfort symptoms. 2. Drug therapy: Usually myocardial ischemia will cause heart failure. Therefore, medications such as hydrochlorothiazide, metoprolol, enalapril and digoxin can be prescribed to lower blood pressure, improve the symptoms of cardiac insufficiency and alleviate the discomfort. 3. Surgical treatment: When coronary artery stenosis is >70%, cardiac stent implantation is needed for treatment, after implantation, it can improve the symptoms of coronary artery ischemia, make the myocardium reperfusion, and thus improve the related uncomfortable symptoms. When the above symptoms occur, it is recommended to immediately consult a doctor to determine the cause of the disease and then treat the disease under the guidance of the doctor.
