The time of review after stenting is a relative routine, which is applicable for most patients, and the time and content of the review are also suitable for the specific situation of the patient concerned. For most patients, in our hospital generally 2-3 days after surgery, they can be discharged if there are no special complications. This approach has been widely used abroad, and even many patients are admitted and discharged on the same day, and this mode of post-coronary interventional management has been proven to be a safe mode in actual studies. For these patients, we recommend the first outpatient review about 14 days after the operation, and the review items are mainly white blood cell count, platelet count, red blood cell count, blood creatinine, blood urea nitrogen, and electrocardiogram, but any chest discomfort in the meantime should be followed up by electrocardiogram as early as possible; after this review, patients are recommended to come to the cardiology department for monthly review, and the review items are mainly consultations by cardiologists to If the patient is asymptomatic, special examination is not necessary, but for patients with coronary artery disease with diabetes, dyslipidemia and hypertension, blood glycated hemoglobin, LDL, cholesterol, HDL and triglycerides are some necessary items for review, at least once every 6 months, specific In addition, post-coronary intervention patients with history of gastrointestinal bleeding and peptic ulcer and elderly post-coronary intervention patients should also have fecal occult blood test checked every 6 months. More post-coronary intervention patients are concerned about the need to review the stent after it is placed inside the coronary artery. This is a complex question. The need to review special tests (e.g. coronary angiography, coronary spiral CT, myocardial nuclear scan, etc.) should be decided by the cardiologist or cardiac interventional cardiologist, and these post-coronary intervention patients do not need to routinely review these items if they have no clinical symptoms. At 3-6 months after the procedure, for patients implanted with drug-eluting stents, about 10% or less of patients may have a vessel in the area associated with the stented vessel in blockage, a condition that is medically known as in-stent restenosis, and only if the patient’s clinical presentation suggests this condition is it necessary for the patient to undergo a review of special coronary artery investigations.
