One year after stenting, you need to go to the hospital for review. One year after stenting, laboratory tests such as routine blood test, routine urine test, routine stool test, liver and kidney function, blood lipids and blood glucose, as well as electrocardiogram and ultrasound of the heart should be completed. Blood pressure and heart rate should be monitored regularly and recorded, which should be shown to the doctor before going to the hospital and the laboratory tests that were done during the hospitalization for stenting should be brought along. The purpose of the review is to evaluate the heart function through ECG and ultrasound, whether there is any ST-T change in ECG, whether there is any change in ultrasound compared with the previous examination, and to adjust the dose of medication and change the medication under the guidance of the doctor. If there is any discomfort after the stenting procedure, it is recommended to follow up at any time.
