Anti-platelet drugs Aspirin, clopidogrel, tegretol Aspirin + clopidogrel or tegretol is what doctors often refer to as “dual anti-treatment”, that is, dual antiplatelet therapy, which is the key to reducing the risk of blood clots in the stent! After 12 months, the dosage of clopidogrel or tigretol should be adjusted according to the condition of the patient, and if not contraindicated, aspirin should be taken for a long time. If there is no contraindication, aspirin should be taken for a long period of time. Attention should be paid to any bleeding tendency, such as bleeding gums, bleeding spots on the skin, black stools, and regular blood tests. 2. beta-blockers Representative drugs include metoprolol, bisoprolol, carvedilol, etc. These drugs improve the long-term outcome of patients by weakening the myocardial contraction rate, slowing down the heart rate, reducing myocardial oxygen consumption and preventing the recurrence of myocardial ischemia. Heart rate should be closely monitored while taking the medication. The heart rate should not be lower than 50 beats per minute during the medication period, too slow heart rate is also not good for patients, which may cause weakness or even cerebral ischemia. The resting heart rate should be 60 – 70 beats per minute in the morning while taking the drug. 3. Statins Representative drugs include Rosuvastatin, Atorvastatin, Simvastatin, Fluvastatin, etc. Statins can stabilize or reverse atherosclerotic plaques, regulate blood lipids and inhibit the synthesis of excessive cholesterol by the liver. Pay attention to monitoring liver function and the presence of muscle pain during administration. 4. Angiotensin converting enzyme inhibitors (ACEI) These drugs commonly used are captopril, enalapril, perindopril, benazepril, fosinopril and so on. They can promote vasodilation, reduce cardiac load and improve myocardial function; they have an anti-myocardial ischemic effect, thus improving the long-term prognosis of patients. In patients with coronary artery disease, especially those with enlarged ventricles, they also have the effect of reducing ventricular remodeling. In addition, ACEI is highly effective in the treatment of high-risk patients with combined hypertension, diabetes mellitus or a history of old myocardial infarction with myocardial insufficiency. A common side effect is dry cough, with an incidence of 3%-20%. In severe cases, consult your doctor about changing drugs such as sartans (ARB). The medication should be taken on time and in the right amount every day, and the medication should not be stopped or changed without the doctor’s permission, and the specialist should be consulted for the increase, decrease and change of medication.
