Bird’s nest can be eaten just after stenting. Bird’s nest is made up of the saliva of the swiftlet and other substances, containing protein and a variety of trace elements, which can supplement a variety of nutrients for patients with coronary artery disease, and can be used by patients with coronary artery disease after stent surgery. Patients with severe coronary artery stenosis need to implant stents, which can improve the blood supply of the heart muscle. After stenting, patients should strictly control their diets and avoid high-fat foods, as bird’s nests are rich in proteins and low in fat, and eating bird’s nests appropriately will not affect the stents and the recovery after the operation. Patients with coronary artery disease should strictly control their diets, increase the intake of vegetables as appropriate, but pay attention to maintaining a balanced nutrient profile, formulate dietary prescriptions under the guidance of a physician, and scientifically and reasonably control their diets.
