There is no optimal food after cardiac stenting. It is important to pay attention to a low-salt and low-fat diet, and to ensure a balanced intake of nutrients at the same time. After cardiac stent surgery, patients should pay attention to control the intake of high-fat food, and focus on low-salt and low-fat food, such as limiting the intake of animal offal, to prevent high blood lipid levels, and try to eat more green and fresh vegetables, which will not raise blood lipid levels. Ensure a balanced intake of various nutrients, avoiding partiality, and there is no need to go overboard with vegetarian diets. Post-stenting patients should take oral medication under the guidance of a physician on the basis of dietary control, such as aspirin, atorvastatin, metoprolol, etc., to avoid in-stent stenosis, and to better combine medication and food to control blood lipid levels.
