If the patient has a mild stenosis of the coronary artery lumen, it is not serious. Although not serious, it is recommended that patients should take drugs to prevent disease progression, because serious disease is often caused by the progressive development of mild disease without good intervention and treatment. For patients with mild coronary artery stenosis, it is recommended that they should routinely take oral aspirin and statin drugs, with atorvastatin and rasulvastatin as representative drugs. In addition, if the patient still has uncomfortable symptoms after taking aspirin and statin drugs. Considering that it may be caused by the presence of syndrome X or poor microcirculation, it is suggested that patients can take Xigmart orally to help improve the patient’s microcirculation. In addition, it is recommended that patients should pay attention to a low-salt and low-fat diet, quit smoking and drinking, work and rest regularly, and keep a happy mood to better prevent the progression of the disease.
