After the patient has passed the acute phase of acute myocardial infarction, death has left for the time being, but it is by no means all right. If active preventive measures are not taken, it may not be long before a second myocardial infarction comes to the door. At present, the majority of myocardial infarction patients should keep in mind 5 basic measures, the so-called ABCDE program (from the first letter of each English word). A: Aspirin (Aspirin) and ACEI class drugs. The former has anti-platelet agglutination effect and can reduce intracoronary thrombosis, while the latter can improve cardiac function and reduce cardiac remodeling and deformation, which is more helpful for those with combined hypertension and cardiac insufficiency. B: b-blockers (Beta blocker) and blood pressure control (Blood Pressure). It has been demonstrated that if b-blockers are used in post-myocardial infarction patients without contraindications, they can significantly reduce the recurrence rate of myocardial infarction, improve cardiac function and reduce the occurrence of sudden death. The importance of controlling hypertension in the prevention and treatment of coronary heart disease is well known. Generally speaking, controlling blood pressure below 130/80mmHg can reduce the acute events of coronary heart disease, and can reduce the complications of hypertension, such as stroke, renal impairment and fundus lesions, which can kill two birds with one stone. C: lower cholesterol (cholesterol) and quit smoking (cigarettes). As we all know, the increase of cholesterol is the culprit of coronary heart disease. The increase of serum cholesterol should be lowered to below 4.6mmol/L through dietary control and proper taking of lipid-regulating drugs such as statins, which can greatly reduce the recurrence rate of myocardial infarction. Recently, it has been confirmed through evidence-based medical research that patients should take lipid-lowering drugs even if their serum cholesterol is normal after myocardial infarction, therefore, all Patients with myocardial infarction should take long-term statin lipid-lowering drugs regardless of whether their serum cholesterol is normal or elevated. As for the benefits of quitting smoking, everyone knows that it can not only reduce the prevalence of chronic bronchitis, emphysema, pulmonary heart disease and lung cancer, but also reduce the damage of smoke on the endothelium of blood vessels, thereby reducing the occurrence of coronary heart disease. D: Diet control (Diet) and treatment of diabetes (Diabetes). Coronary heart disease in a sense is not control the mouth, eat out. Eating too much cholesterol-rich food such as fatty meat, animal offal and egg yolk every day is the biggest risk factor for coronary heart disease. Therefore, patients after myocardial infarction should stay away from these high cholesterol foods and advocate a light diet with more fish and vegetables and less meat and eggs. Diabetes can not only cause an increase in blood sugar, but also an important cause of lipid disorders. Under the same conditions, the prevalence of coronary heart disease in diabetic patients is 2-5 times higher than that in patients with normal blood sugar. This shows how important it is to control diabetes to patients with coronary heart disease. E: education and physical exercise. Patients with coronary heart disease should learn some common sense about angina, myocardial infarction and other acute coronary syndrome first aid, such as the occurrence of angina or myocardial infarction symptoms can contain nitroglycerin and heart pills, do not underestimate these simple methods, can greatly reduce the condition and reduce the rate of death, myocardial infarction with the body gradually recovered, according to their respective conditions under the guidance of doctors, appropriate to participate in physical exercise and weight loss, so that Not only can enhance physical fitness, but also is an important measure to reduce the recurrence of myocardial infarction in coronary heart disease. In conclusion, if the majority of post-infarction patients can follow up regularly under the guidance of doctors, remember and adhere to the above ABCDE program, I believe that many patients with coronary heart disease myocardial infarction can still go to work and lead a normal life and enjoy their life.
