After stenting, patients often feel that the disease has been cured, the root of the disease has gone, take a year of medicine, and so on after the stent grows in the blood vessels, everything can be fine, forgetting that they are still a patient with coronary heart disease. 1. Note: After the stent treatment of coronary heart disease, not everything is fine, and the following problems may exist: 1. The risk factors causing coronary heart disease, such as hypertension, diabetes, hyperlipidemia, still exist and will not disappear by themselves. Second, after interventional treatment, what drugs should be taken? 1. Combined application of antiplatelet drugs: Because the part of the blood vessel implanted with stent is very easy to form intra-stent thrombus without the protection of effective antiplatelet drugs, and the consequence is no different from another myocardial infarction. After stent placement by interventional procedures, combined antiplatelet therapy, such as aspirin and clopidogrel (domestic Tega, imported Bolivar), or aspirin and tegretol (Belinda), must be routinely used. In today’s increasingly widespread use of drug stents, the combination of antiplatelet agents should be used for at least one year under medical supervision if there are no contraindications, and after one year, the decision to discontinue Polivic, Tegretol or Bactrim should be made depending on the number of stents and the site of implantation. Aspirin, on the other hand, is applied for life, but adverse reactions in the digestive tract, such as whether the stool is black, need to be evaluated. 2. Lipid-lowering drugs, including various statins: Lipitor (atorvastatin), cortisol (resevastatin), sulforaphane (simvastatin), and lexapro (fluvastatin) are commonly used. Patients with coronary artery disease use statin not only to lower lipids, but because it is the only class of drugs that can slow down the progression of atherosclerosis and stabilize its plaque. It must be taken regularly and in sufficient quantity for a long period of time, and the indicators of lipids must be tested annually to meet the criteria for preventing atherosclerosis (LDL-TC controlled at 1.8 mmol/L or less). Do not think that your blood lipids are within the normal range and stop the medication on your own. 3, the control of hypertension drugs are: (1) betalactam, mainly to control sympathetic excitation, control blood pressure caused by mental factors elevated. Most patients with coronary artery disease are impatient, irritable, poor patience, emotional contrasts, high volatility of the nervous system, the need for long-term regulation of this drug. The heart rate is generally required to be controlled at about 60 beats/min. (2) Drugs to control increased vascular tension: many drugs with the word “priligy” at the end, such as captopril, perindopril (Yashida), benazepril (Lortin), ramipril, etc. Or “sartan” drugs such as coxsartan (Coxsartan), valsartan (Dextran), etc. By taking these drugs for a long time, we can remove many unfavorable factors that affect vascular lesions and achieve the purpose of controlling vascular lesions in other parts of coronary heart disease. Some patients do not have high blood pressure why do they need to use it, to put it plainly is to use these drugs to improve the prognosis of coronary heart disease. 4, angina control drugs: some patients still have angina symptoms after stent implantation, need to continue to take nitrate drugs such as Xinkang, Imodium, Isradin, etc.. There are also metabolic drugs such as trimetazidine (Vanzantine), etc. Sometimes angina symptoms are not obvious, you can stop using these drugs. 5.Strict control of blood sugar, such as oral medication or insulin application, etc. The fasting blood sugar of diabetic patients should be controlled around 6mmol/L, and the blood sugar of 2 hours after meal should be controlled within 8mmol/L, and the glycated hemoglobin should be less than 6.5%. Remember: it is important to take the medication and not to stop it easily. When and what should be reviewed after cardiac stenting? Outpatient review is often required 1 month, 3 months, 6 months and 1 year after stent implantation. 1.Blood routine: Anti-platelet drugs may affect platelets and white blood cells, so during the period of taking them, especially at the beginning, you need to review the blood routine at the outpatient clinic. If there is rash, skin bleeding spots and bruises, and other bleeding conditions, you should go to the hospital promptly and check the coagulation index if necessary. If there are black stools and red urine, the stools and urine should be tested. 2. Lipids, blood glucose, liver function, kidney function, cardiac enzymes (creatine kinase CK): mainly observe the lipid compliance, and also observe the adverse drug reactions. Patients should be informed that statin lipid-lowering drugs have adverse reactions of liver function damage and muscle damage, however, the incidence of adverse reactions is very low. Generally, glutamic oxalyl transaminase and glutamic alanine transaminase are elevated more than 3 times, and CK is elevated more than 5 times before discontinuing or switching to statin lipid-lowering drugs. Liver function can generally be restored after stopping the drug. 3.Electrocardiogram: The review of electrocardiogram is mainly to observe the heart rate, arrhythmia, the presence of myocardial ischemia, etc.. It is best to bring the electrocardiogram before and after the onset of the disease for comparison to see if there are any changes. If the patient still has angina symptoms, sometimes a 24-hour ambulatory ECG is needed. 4.Cardiac ultrasound: It is necessary for patients with myocardial infarction to review cardiac ultrasound in 3 months or half a year, mainly to observe and measure the changes of cardiac function. 5.Coronary angiography: The review should be combined with clinical symptoms. If there are still typical symptom attacks, it is recommended to review coronary angiography; if the condition is stable and the patient does not have the will to review angiography, it is not necessary to do angiography. Fourth, how should I control my diet after coronary stenting? When choosing foods for patients with coronary artery disease, they should choose foods that are low in fat and cholesterol and high in vitamins, dietary fiber, beneficial inorganic salts and trace elements, and have lipid-lowering and anticoagulant properties. Specific food can be selected from the following categories: (A) foods that can be eaten freely ① various cereals, especially coarse grains. ②Soybean products. ③Vegetables, such as onions, garlic, golden cauliflower, mung bean sprouts, lentils, etc. ④Mushrooms and algae, such as mushrooms, fungus, seaweed, nori, etc. ⑤ Various kinds of melons, fruits and tea. (B) Appropriate food ① lean meat ② fish ③ vegetable oil, including soybean oil, corn oil, sesame oil, peanut oil. ④ milk, including defatted milk and its products ⑤ eggs, including egg whites, whole eggs (2~3 per week). (C) Eat less or avoid food ① animal fat, such as lard, butter, mutton fat, chicken fat, etc. ② fatty meat ③ offal such as brain, bone marrow, etc. ④ avoid shellfish ⑤ sugar, tobacco, alcohol, chocolate, etc. Strictly quit smoking and limit alcohol: smoking is one of the most important factors of coronary heart disease, so patients with stent placement must quit smoking, otherwise the stent is prone to restenosis or in-stent thrombosis. It is better to abstain from alcohol. V. How should I exercise after stenting? Exercise should be asymptomatic, that is to say, no angina symptoms should be present during exercise. According to the stability of the arterial lesion, determine the type and intensity of activity; unrealistic strong exercise or resting to recuperate from illness may not be scientific and reasonable. One of the most cost-effective methods of recovery is through appropriate physical activity under medical supervision. It is recommended to exercise in the afternoon. If you have the habit of exercising in the morning, it is recommended to drink a glass of warm water (not cold nor hot) after washing and brushing up in the morning, and go for morning exercise only after 5 minutes. If the person is 60 years old, it should be controlled at 180-60 = 120 beats/min or less. When waking up in the morning, do not get up and out of bed immediately, you should be awake for about 5 minutes before sitting up. It is not advisable to engage in work that causes excessive mood swings. Emotion and psychological rehabilitation: Psychological health is very important to the recovery of coronary heart patients, the key is to achieve “happy mood, eliminate hostility”, the best way to achieve “numbness”. Sixth, after the interventional surgery encountered such a situation should do? 1.Acute attack of angina: If you have an acute attack of angina after coronary stenting, keep calm, stop all activities and rest in place. Immediately sublingual nitroglycerin 1 tablet or quick-acting heart pills 10. If the effect is not good, it should be taken every 5 minutes. If there is still no effect for 3 times, call 120 immediately and go to hospital as soon as possible. 2.Travel: After coronary intervention, patients should bring their own emergency medicine box (nitroglycerin, quick-acting heart pills, etc.) and daily oral medicine, especially aspirin and clopidogrel taken after the intervention should not be forgotten. When you travel, your diet is often irregular, but you must take your medication on time. If you have an angina attack that cannot be relieved by oral medication, go to the nearest local hospital immediately and take a nitroglycerin every 5 minutes on the way, or take orally or chew a Betalac tablet if your pulse is fast (>70 times/minute). If frequent attacks of angina pectoris, or an attack of acute myocardial infarction, you should immediately go to the nearest hospital with intervention conditions to actively control the disease and avoid the possible dangers on the way home. 3, conjugal life: conjugal life is very physically demanding. After the intervention, if the stent is not restenosed and there are no new lesions in the coronary arteries, etc., normal conjugal life should not be affected. However, patients should exercise discretion according to their own conditions. If patients are worried about inducing angina, they can take anti-cardiac pain and/or betalactone beforehand, which will be effective in preventing angina attack. 4.Cold, fever and diarrhea: At present, there is no conflict between the drugs after coronary intervention and anti-cold drugs, antipyretics and drugs for diarrhea in general. However, patients should pay attention to the fact that blood volume is often insufficient when they have cold, fever and diarrhea. Patients should reduce or stop the use of antihypertensive drugs according to the blood pressure situation at that time, so as not to cause excessive reduction of blood pressure. However, beta-blockers such as betalactam and atenolol should not be discontinued as much as possible. 5. Perform other examinations, such as magnetic resonance imaging (MRI), etc.: Patients after coronary intervention generally do not affect the performance of other examinations, but for special examinations such as MRI, it is recommended that patients should preferably be examined 3 months after the intervention. Before performing other examinations, patients should inform their doctors that they are taking aspirin, clopidogrel, statins and other drugs for post-interventional procedures. 6. Undergoing other surgeries: Patients with coronary artery disease should inform the surgeon of their past medical history before undergoing other surgeries so that the surgeon can weigh the pros and cons. Anticoagulants such as aspirin and clopidogrel should be discontinued before general surgical procedures to avoid intraoperative hemorrhage. However, patients who are within 3 months after bare metal stent placement or within 1 year after drug stent placement, discontinuing the above drugs can induce in-stent thrombosis, causing acute myocardial infarction and threatening the patient’s life. Therefore, post-interventional patients should try not to undergo surgical procedures during this period. If surgery is necessary, aspirin and clopidogrel can be discontinued for 5-7 days under close inpatient supervision and subcutaneous injection of low molecular heparin can be applied at the same time, but there is still a possibility of myocardial infarction. Conclusion: Intracoronary stent placement is only the first step of a long journey, and maintaining the stent is the key.
