Anticoagulants prevent in-stent thrombosis, and in addition, patients need to use antiplatelet coagulants as well as statins as prescribed by their doctor. If the patient has had cardiac stenting or stenting procedures such as intracranial stenting or vascular stenting, blood clots may occur after the procedure. At this time, you need to use anticoagulant drugs under the guidance of the doctor, such as warfarin, heparin sodium, low molecular heparin calcium, etc., which can effectively prevent the formation of blood clots in the stent. In addition, patients who have had stent surgery also need to use aspirin, clopidogrel and other anti-platelet aggregation drugs under the guidance of the doctor. For patients with high blood lipids, they need to use statins such as simvastatin and atorvastatin as prescribed by the doctor, which can effectively reduce blood lipids. It is recommended that patients undergoing stent surgery need to consult a doctor in a timely manner, and the doctor will determine whether anticoagulants and other medications are needed according to the patient’s condition.
