First, correct the treatment misconception – coronary artery disease is “cured”. The current level of medical development cannot cure coronary heart disease because it cannot fundamentally change the process of coronary artery atherosclerosis, but only increase the blood supply to ischemic myocardium by increasing the diameter of narrow artery lumen, and various drugs or surgical treatment measures only achieve the purpose of relieving symptoms and delaying the development of the disease. In addition, many high-risk factors of coronary heart disease are not well controlled, the newly erected vessels will gradually develop lesions, and new lesions may appear in the original normal coronary arteries. Second, long-term drug treatment. You should usually receive regular medication and diuretic therapy if necessary. Anti-thrombotic (anti-platelet, anticoagulation): aspirin, warfarin, Bolivar (clopidogrel hydrogen sulfate tablets) Reduction of myocardial oxygen consumption (beta-blockers): metoprolol succinate tablets Relief of angina (nitrates): isosorbide mononitrate tablets Lipid regulation and plaque stabilization (statin lipid regulators): simvastatin tablets. Third, control the primary disease, such as hypertension, diabetes, etc. Hypertension is an independent risk factor for the development of coronary heart disease. The most common hazards caused by atherosclerosis due to elevated blood pressure are coronary arteries and cerebral arteries. Coronary artery atherosclerosis patients 60% to 70% have hypertension. The fact that diabetes mellitus predisposes to cardiovascular disease is well established. Some data show that the incidence of this disease in diabetic patients is two times that of non-diabetic patients. Fourth, lifestyle changes: quit smoking and limit alcohol, low-fat and low-salt diet, appropriate physical exercise, weight control, etc. 1, diet: often eat a higher calorie diet, more animal fat, cholesterol susceptible to this disease. At the same time, the large amount of food is also susceptible to this disease, so to control the incidence of coronary heart disease, in addition to control the intake of high-fat diet, must also pay attention to control the amount of food. 2, control lipids: due to genetic factors, or excessive fat intake, or lipid metabolism disorders resulting in dyslipidemia. Such as total cholesterol, triglycerides, LDL, VLDL increased, while HDL decreased, prone to the disease. 3, quit smoking: smoking is the main risk factor for coronary heart disease. Smokers compared with non-smokers, the morbidity and mortality of the disease increased by 2-6 times, and is proportional to the number of cigarettes smoked per day. 4, weight control: over the standard weight of obese people (10% overweight for light, 20% for medium, 30% for severe obesity), susceptible to the disease, especially those who gain weight rapidly. However, it is currently believed that attention should be paid to the study of methods of evaluating body weight. Instead of looking at body mass index alone, the thickness of subcutaneous fat should be measured. There have been prospective research data show that centripetal obese people have a greater risk. V. Periodic review 1. Generally, regular reviews are conducted 1 month, 3 months, 6 months, 1 year, 2 years, etc. after surgery. 2.Main items for review: electrocardiogram, echocardiogram, multilayer spiral CT (non-invasive, low-risk, rapid, and commonly used means of examination). Blood tests: complete set of coagulation, blood glucose, blood lipids, liver and kidney function, myocardial damage markers. Possible problems after coronary artery bypass grafting Wound pain: slight pain and discomfort may occur from 3 to 9 months after surgery, but the nature of the pain is completely different from angina and will gradually decrease. Lower extremity edema: The lower extremity on the side of the removed vessel will generally have varying degrees of edema for 3 months after surgery, decreasing in the morning and increasing in the afternoon. This is because the blood return is temporarily affected to varying degrees after the saphenous vein is removed. After surgery, elastic stockings can be worn, the affected limb elevated, and appropriate amounts of diuretics can be taken. Post-bridge angina attack: This needs to be distinguished from post-operative incisional pain. In case of angina, you should consult a doctor promptly to clarify the cause of angina as early as possible and treat it correctly. Cardiac insufficiency: Patients with recurrent infarction and extensive anterior wall infarction are prone to cardiac insufficiency, which often manifests as panic, shortness of breath, inability to lie down at night in severe cases, accompanied by lower limb edema and abdominal distension. If the above symptoms appear, you should seek medical treatment promptly and actively treat the symptoms.
