There are patients who come to our hospital for follow-up after stent surgery every time we see them in the outpatient clinic, some from the city and some from overseas. In fact, stenting is an increasingly popular procedure. In fact, stent surgery, as an increasingly popular treatment method, should have a standard follow-up plan, and the same plan should be followed no matter where the surgery is performed, so that the post-operative treatment and follow-up are homogeneous, so that patients can have a good idea of what to expect and come for checkups at an early time and plan well. The specific items are mainly laboratory tests, electrocardiogram, ultrasound, coronary CTA or coronary angiography: 1. These tests are mainly to observe whether the anticoagulant drugs and statin lipid-lowering drugs have caused any side effects, and if so, the type or dose of medication should be adjusted in time. In addition, for patients with a history of myocardial infarction, BNP, an indicator of cardiac function, should also be checked. 2. ECG (review in January, March and June) An ECG can detect any myocardial ischemia or arrhythmia, and can also be used as a control before surgery. 3.Echocardiography mainly observes whether the heart size and heart function have improved after stenting. For patients who have been followed up after heart attack, they should be routinely examined every time. If there is no history of heart attack, ultrasound can be done at the six-month follow-up. 4.Coronary CTA or coronary angiography (one year review) One year after stenting, coronary CTA examination or coronary angiography can be reviewed to evaluate whether the stent is patent and whether there are new stenoses or other vascular lesions progressing. In conclusion, stent surgery is only to open up the narrowed blood vessels, maintaining blood vessel patency and preventing the progression of other blood vessels is a long-term task, after discharge from the hospital, do a light diet, combine work and rest, take medication on time, and follow up regularly. If you have any change or progress in your condition, it is recommended to go to the hospital for checkup at any time, rather than waiting for the above mentioned follow up time.
