It is impossible for a stent to support the whole life, the stent is at most a “plumber”, and the whole body environment has to be managed comprehensively for the whole body to flow smoothly. The following aspects should be noted after the heart stent surgery. 1, after the heart stent surgery, patients should adhere to the medication, pay attention to self-observation. After heart stent surgery, because more kinds and quantities of drugs have to be taken, if patients have symptoms such as bleeding from the skin or gastrointestinal tract and fatigue and weakness, they should immediately go to the hospital for relevant examination. After heart stent surgery, if the patient wants to receive other treatment and needs to stop taking medication, he or she must discuss with the attending doctor before deciding. 2, after heart stent surgery, patients should have regular checkups. Including blood pressure, blood sugar, blood lipids, liver and kidney function and other items, the original hypertension, diabetes and cerebrovascular disease patients, pay more attention to the treatment of the original disease and regular examination, if the index is higher than the normal range, we must actively take treatment measures. 3, moderate exercise, maintain a stable and optimistic mentality, is also the principle that must be followed after heart stent surgery. However, the exercise of patients with coronary heart disease should bear in mind that it is important to arrange the amount of activity correctly and reasonably, and the size of the activity must be combined with their own situation and carried out gradually under the advice of doctors. At the same time, consciously quit smoking and drinking, maintain a low-sugar, low-fat diet, and develop the mental behavior habits of not being in a hurry and moderate work and rest. 4, after heart stent surgery, although the patient’s chest pain and chest compression symptoms disappear, but the operation only solves a small section of the blood vessel, if the risk factors of hypertension, high blood pressure and high blood sugar still exist, it will still cause damage to the inner wall of the blood vessel. Therefore, patients with hypertension, hyperlipidemia and diabetes need to insist on taking long-term antihypertensive drugs, lipid-lowering drugs and sugar-lowering drugs after stenting. 5, after heart stent surgery, patients can eat more fiber-rich foods, such as various vegetables, fruits, brown rice, whole grains and beans, which can help defecate, prevent constipation, stabilize blood sugar and lower blood cholesterol. Eat less fatty meat, offal, fish eggs, cream and other foods with high cholesterol; choose more fish, skinless chicken, etc. with less fat content; eat 1-2 whole eggs per week.
