Dizziness after heart stenting is considered to be related to heart disease, high blood pressure, cervical spondylosis and other factors. It is recommended to consult a doctor in time to find out the cause of the disease and treat it actively. 1. Heart disease: If the patient has serious heart failure or arrhythmia, it may cause dizziness due to insufficient blood supply to the brain. It can be treated with drugs such as Atenolol and Lidocaine under doctor’s guidance. 2. High blood pressure: If there is a sudden increase in blood pressure after cardiac stenting, it may also cause dizziness. It can be treated with drugs such as amlodipine and timosartan under doctor’s guidance. 3. Cervical spondylosis: If patients have cervical spondylosis after heart stenting, it will lead to dizziness, which can be treated with drugs such as ibuprofen and etoricoxib under doctor’s guidance, and surgical treatment if necessary. Therefore, patients with dizziness after cardiac stenting are advised to seek timely medical attention to identify the cause of the disease and actively treat it.
