Prone angina belongs to unstable angina, which means that an attack of angina can be induced when the patient is lying down. The reason is that when the patient is lying down, the return blood flow increases and the cardiac load is increased, which leads to relative ischemia and hypoxia and induces angina. Treatment usually includes general treatment, drug treatment, and surgical treatment.
1. General treatment: elevate the head of the bed to reduce the return blood flow, which can reduce the cardiac load, chest tightness and chest pain, dyspnea can be treated with oxygen, and usually do low-salt and low-fat diet.
2. Drug therapy: mainly including aspirin, clopidogrel bisulfate and other antiplatelet agents, atorvastatin and other lipid-lowering agents, isosorbide mononitrate and other vasodilators, etc., which can prevent thrombosis aggravation and improve the symptoms of myocardial ischemia, with hypertension, diabetes mellitus and other underlying diseases, such as taking valdecoxib, metformin and other drugs to control risk factors.
3. Surgery: including coronary stent implantation, coronary artery bypass grafting, etc., which mainly opens the diseased blood vessels and restores the normal blood supply to the myocardium, and plays a very important role in improving the symptoms of angina pectoris and reducing the risk of the disease.
If patients experience angina symptoms such as chest tightness and chest pain, sweating, and dyspnea when lying down, it is recommended that they go to the hospital in time, combine with coronary CTA or imaging and other tests to clarify the stenosis of blood vessels, and follow the doctor’s instructions for active treatment.
