One heart vessel has a stent and the other does not have a stent, and the existing symptoms need to be judged according to the condition of the patient’s blood vessel, and the stent should be put in again when the blockage or stenosis is more serious. If the other blood vessel is asymptomatic and the blockage is mild, it can be relieved by taking anticoagulant medication. However, if there are already symptoms, it is recommended to go to the hospital in time for an arteriogram to clarify the blockage and stenosis of the blood vessel, and to follow the doctor’s instructions for treatment. If the blockage of blood vessels is not serious and the symptoms are relatively mild, you can use aspirin, clopidogrel bisulfate, atorvastatin and other drugs to treat. If the blood vessel blockage is more serious, and the patient’s symptoms are more serious, such as angina, dyspnea, decreased activity endurance, etc., and even fainting, shock and so on. At this time, stenting should be carried out in time. It is recommended that patients seek medical treatment in time and choose the appropriate treatment under the guidance of the doctor.
