Coronary heart disease is a complex disease whose etiology and pathogenesis have not yet been fully elucidated, and it has a variety of clinical risk factors. Whether it is stenting, bypassing, or purely pharmacological treatments, all of them are only aimed at localizing stenotic lesions, restoring their blood flow supply, or controlling the progression of the lesions, but they do not solve the underlying causes of atherosclerosis and vascular stenosis. Therefore, if patients are left to their own devices, if their lifestyles are not counseled, and if atherosclerosis risk factors are not controlled or poorly controlled, the risk of in-stent restenosis or the emergence of new vascular lesions, or the aggravation of existing lesions increases significantly, and if the use of antiplatelet drugs is insufficient, thrombi may be formed within the stent, leading to serious consequences. Therefore, it is very important to strengthen the postoperative management and scientific follow-up of patients with coronary artery disease. Currently, the more reasonable review cycle arrangement is: the first outpatient review 2 weeks after discharge, followed by a review every 3 months in the first year, half a year in the second year, and then once a year. If there is no special change, you can take the medication nearby, but if there is a recurrence of symptoms, side effects of medication and other special circumstances, you should consult the doctor in time.
