Coronary stenting can improve the quality of life and prolong the survival time of patients with coronary artery disease, and is an effective treatment for coronary artery disease, but it must be noted that coronary stenting is different from most surgical procedures. Therefore, there are many things to pay attention to after stenting: 1. Make sure to adjust your lifestyle: including low-salt and low-fat diet, quit smoking and limit alcohol, exercise properly, and reduce weight, etc. See my popular article “Non-pharmacological treatment of hypertension”. I have seen patients who had myocardial infarction in their twenties, but for no other reason than smoking; I have also seen many patients who still smoked after stenting, but often felt chest pain or even had another heart attack. Wuhan Union Hospital Cardiovascular Medicine Zhou Zihua 2, control other cardiovascular risk factors: mainly including hypertension, diabetes and high blood lipids, etc., must be controlled at the target level. 3, post-stenting drug therapy: this point is crucial. Many patients think that after spending so much money, is it possible not to take coronary heart disease drugs after stenting? In fact, it is not, in a sense, the drugs that must be taken in the first year after stenting may be more, especially the anti-platelet drugs, such as failure to adhere to, may be more dangerous according to the stent than the uneasy stent. The main drugs after stenting are: (1) anti-platelet drugs: At present, they mainly include aspirin and clopidogrel, the former must be taken for life, the latter for at least 1 year, and more dangerous parts or more stents need to take longer. Generally 0.1g/day, pay attention to the color of stool, whether there is gastrointestinal bleeding; clopidogrel 150mg/day for the first 2 weeks, after 2 weeks changed to 75mg/day, but I have encountered several cases of clopidogrel dose reduction and then chest pain, so I generally recommend patients, especially patients who have not quit smoking 1 month later changed to 75mg days. (2) Anti-atherosclerotic drugs: mainly include aspirin, ACEI class (such as **pril), Beta blockers (such as **loer), statin lipid-regulating drugs, mainly to control the reoccurrence of stenosis in the stent or other parts. If ACEI is not tolerated, it can be replaced with ARB class (such as **sartan); if Beta blocker is not tolerated, it can be replaced with non-dihydropyridine calcium antagonists, mainly diltiazem. (3) Anti-myocardial ischemic drugs: mainly include nitrates, non-dihydropyridine calcium antagonists, Beta blockers, and other trimetazidine, nicorandil, etc., which are chosen according to the angina pectoris situation. (4) Other: such as drugs to protect the stomach, as well as the aforementioned drugs to control other risk factors such as antihypertensive, hypoglycemic, etc. 4, post-stenting monitoring, inspection content: (1) monitoring blood pressure, heart rate, blood glucose: blood pressure is controlled at least below 140/90mmHg, diabetic patients at 130/80mmHg or less, of course, not too low, diastolic blood pressure should not be less than 60-70mmHg The heart rate should be 55-60 beats per minute; fasting blood glucose should be at least 7mmol/L, preferably below 6mmol/L, and 2 hours after meal should be at least 10mmol/L, preferably below 8mmol/L. (2) Routine blood test: review once in a month or so at the beginning, and then once in 2-3 months according to the situation. Mainly observe the number of platelets, as both aspirin and clopidogrel have an effect on platelets; also observe the number of white blood cells, although the side effect of myelosuppression occurring with clopidogrel is rare; the decrease in hemoglobin should be noted for reasons such as blood loss. (3) Liver function and lipids: Statin lipid-regulating drugs have certain effects on liver damage, although the incidence is small, generally the first 3 months does not occur, the chance of occurring later is also very small, so the first 2-3 months monthly review once, after 3 months review once can be. (4) Electrocardiogram and cardiac ultrasound: If you have chest pain, chest tightness, panic attacks and other symptoms, you should review the electrocardiogram, and if not, review it once every six months. If you have old myocardial infarction or heart failure, you should review your heart ultrasound about half a year or so, except when your condition changes. (5) Coronary angiography: generally there is no need to routinely review, but if there are symptoms of chest tightness and chest pain, it is still recommended to review. The coronary CTA (i.e., multi-row CT) of lesions within the stent is not clear, and direct coronary angiography is still recommended for patients after stenting, and the effect of coronary CTA is slightly worse. 5, if there is discomfort immediately to the hospital: if the risk of recurrence of coronary artery disease is higher after stenting, it should not be taken lightly. It should be noted that even if all these are done very well, there are still some patients who will have recurrence of coronary heart disease because the cause of atherosclerosis is still not completely clear, and there may be other factors that cause atherosclerosis; in addition, there are some factors that cannot be controlled such as genetics, age, etc. As we grow older, atherosclerosis will progress more or less. However, at least with complete attention to the above, your chances of recurrence of coronary heart disease will be significantly reduced. Finally, I wish all of you who have had stenting a healthy and happy life. Department of Cardiology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology
