Stents can be placed at the same time as a cardiogram. If a coronary angiogram reveals that the patient has severe stenosis, and the patient has symptoms, and the electrocardiogram and other data confirm that the stenotic vessel is the patient’s offending vessel, called the target lesion, stenting can be done at the same time. However, for elective patients, the patient’s systemic condition must be fully evaluated before the imaging is done, such as the patient’s comorbidities, the presence of malignant tumors, the risk of bleeding, and the patient’s renal function, all of which must be fully evaluated before the intervention can be done at the same time as the imaging. If we do not have a complete understanding of the patient, we suggest that the patient should have an imaging first and then do elective treatment after the assessment is clear. If the patient is a patient with an emergency myocardial infarction, it may not be possible to go for a complex evaluation and an emergency angiogram with simultaneous stent placement is required. It is important to consider that the patient may develop or find extracardiac disease after the procedure, so a bare stent or a new generation drug-coated stent is recommended at this time.
