1.What are the possible symptoms after coronary interventional stenting? (1) The stent, as a foreign body, may be discomfort or pain in the precordial area, which may be caused by the following reasons: (1) The stent, as a foreign body, may be discomfort in the coronary artery, just like a person who has a denture installed, and the patient may experience pain and discomfort in the precordial area because of excessive psychological tension, but it is completely different from the preoperative angina, and the electrocardiogram and myocardial enzyme profile are normal. It may heal spontaneously in the short term. (2) Postoperative complications of acute vascular occlusion, intracoronary thrombosis or acute myocardial infarction. Such cases need emergency coronary angiography to confirm the diagnosis and emergency intervention again to cure. 2.When should the patient get out of bed after interventional stenting? The time for patients to get out of bed after surgery should be determined according to their conditions. Patients with acute myocardial infarction need a longer recovery period due to partial myocardial necrosis, and generally need to get out of bed 4-5 days after surgery, but when serious complications such as arrhythmia, cardiogenic shock and heart failure occur, it will take 5-10 days to get out of bed. Generally, patients with coronary artery disease can get out of bed 24 hours after surgery, and can be discharged from the hospital after 3-4 days. 3.Do I need coronary angiography review after coronary interventional stenting? At present, 99% of interventional stenting procedures are drug-coated stents (DES), and less than 5% of patients may have restenosis after successful surgery. Therefore, generally, only when patients have symptoms of angina again will they consider whether restenosis has occurred and consider CTA or even coronary angiography review as appropriate. Once restenosis is detected, drug-coated stents can be implanted again to solve the restenosis problem. 4.Will the stent collapse, displace or rust if it is implanted in the body? Interventional stents are generally made of stainless steel alloy, which has strong support, corrosion resistance and plastic memory function, and will not rust or collapse. The high pressure given during the operation of stent expansion is more than 6-8 times the pressure of a car tire, so that the stent is tightly embedded in the coronary artery wall and therefore will not displace. 5.When can coronary heart disease patients work after interventional stenting? After the interventional stent treatment for coronary heart disease patients, the problem of coronary artery stenosis is fundamentally solved, so the quality of life of patients after the operation is obviously improved, and generally patients can go to work 7 days after the operation. Patients with acute myocardial infarction can go to work after 3-8 weeks after surgery. 6.How to control the amount of activity after coronary interventional stenting? Postoperative activities should be gradual, from light work to heavier work, and the maximum workload should not exceed 70-80% of the preoperative workload, because it is very important to reduce the mental and physical load to prevent and treat coronary heart disease. Activities can be insisted on swimming, walking, jogging, slow dancing, cycling, tai chi, etc. Generally patients can be competent to travel, go abroad and other work. 7.What drugs should be taken after coronary interventional stenting? The purpose of postoperative medication is mainly to prevent restenosis, the main drugs: (1) anti-platelet drugs, aspirin 300mg once a day, changed to 100mg once a day after a month, long-term oral. Poli S 75mg once a day. The length of time this drug is used varies from hospital to hospital, generally ranging from 1 month – 1 year, if economic conditions allow, it is recommended to take long-term oral. (2) Lipid-regulating drugs of the statin class, generally commonly used Lipitor, Prasugol, Sulforaphane, etc. Even if the cholesterol is normal, it should be taken. This drug has proven to be positive in preventing restenosis and new coronary stenosis. Minimum use is 6 months – 1 year. Long-term use is recommended if there are no side effects. (3) Beta-blockers, such as Betaloc, Conoco, etc., are recommended for long-term use if there are no contraindications. (4) Long-term use of antihypertensive drugs and hypoglycemic drugs in patients with hypertension and diabetes. Effectively control blood pressure and blood sugar within the normal range. 8.Is it necessary to take nitrate drugs after coronary interventional stenting? The dose and duration of treatment are based on whether the patient has angina and ischemia after stenting. For patients who have not dilated all stenotic lesions, the use of Lunan Xinkang 20mg twice a day after stenting is generally helpful to control the symptoms and development of coronary artery disease, and for patients who have dilated all stenoses, the above drugs are generally taken 1-2 weeks after stenting to prevent coronary spasm. 9.What are the general precautions after coronary interventional stenting? (1) Adhere to the medication according to medical prescription to prevent intra-stent thrombosis and restenosis. (2) Prevent the development of atherosclerosis, quit smoking and control alcohol; low cholesterol and low animal fat food; keep body weight in the normal range; adhere to regular and relaxing physical exercise and physical work; keep a happy spirit and change the impatient and irritable character; ensure enough sleep; reduce mental stimulation and tension. (3) Keep blood pressure, blood glucose and blood lipids normal. (4) Go to the hospital promptly for examination if there is pain or discomfort in the precordial region. (5) Pay attention to the side effects of the drugs taken after surgery. (6) Review regularly as prescribed by the doctor. (7) Avoid MRI examination as much as possible. 10.How to regulate the diet after coronary interventional stenting? Mainly: Limit the amount of diet appropriately and do not eat full meals. Eat relatively light food, more fresh fruits and vegetables, legumes and foods with high protein. Control the intake of high cholesterol food and animal fat. Control the amount of sweet food. Patients with high blood pressure, control the intake of salt.
