We have done a lot of popular articles about coronary heart disease, but we still often receive similar questions: “How to prevent recurrence after being diagnosed with coronary heart disease?” Today we are going to talk about how to prevent recurrence after having coronary heart disease! The common angina pectoris, myocardial infarction, ischemic heart disease, asymptomatic myocardial ischemia and sudden death are all coronary heart disease, the full name of coronary heart disease is coronary atherosclerotic heart disease, the key is to transport blood to the heart of the coronary artery blood vessel traffic blockage, and cerebrovascular disease, it is also a progressive process, the first onset of the disease, although timely treatment to control the disease, but the future still Therefore, secondary prevention for patients with coronary heart disease is particularly important. The fundamental principles of secondary prevention for patients with coronary heart disease are: improving lifestyle, standardizing medication, avoiding causative factors, and regular reexamination. Improving lifestyle 1. Reasonable diet: avoid overfeeding at each meal and avoid high-fat and high-salt diet to reduce the burden on the heart. Advocate a light diet, eat more fresh vegetables and fruits, ensure balanced nutrition, eat less and more meals, and control weight, especially waist circumference. 2, adhere to exercise: patients with coronary heart disease can be under the guidance of doctors, according to their own conditions, appropriate to participate in physical exercise, obese patients need to lose weight. This not only enhances physical fitness, but also is an important measure to reduce the recurrence of coronary heart disease heart attack. Exercise time seven days a week (at least five days a week), about 30 to 60 minutes of medium-intensity exercise, such as general household chores, brisk walking, Tai Chi, etc. 3, quit smoking and limit alcohol: completely quit smoking, this whole society is promoting, as coronary heart disease patients do not hesitate, completely quit it; avoid strong alcohol, limit drinking a small amount of low alcohol. Patients with coronary heart disease should avoid these triggers: including full meals, excessive exertion, exertion, rage, terror, dry stools, alcohol consumption, heavy smoking, cold stimulation, orgasm, etc. Standardized medication Medication is a key part of secondary prevention for patients with coronary heart disease, which is directly related to whether the disease can be controlled, stabilized, improved, quality of life, and whether to avoid re-occurrence. The standard medication is about effective drugs, effective dose, do not eat stop, not on time medication, if there is no medical advice is best not to easily stop medication. 1, aspirin: platelets are the “culprit” of thrombosis in the coronary arteries, aspirin is currently the best antiplatelet agents for secondary prevention. Small doses of aspirin (75~150mg/d) can reduce the risk of cardiovascular death in patients with chronic stable angina, with little gastrointestinal side effects, cheap and easily available, and should be taken by patients without contraindications. For those who are allergic to aspirin or cannot apply it, clopidogrel can be used as an alternative treatment. 2, β-blockers: can reduce the risk of sudden cardiac death by 30 to 50%, greatly increasing the insurance factor for patients with coronary heart disease, as long as there is no contraindication, β-blockers should be used as the initial treatment of stable angina. The dose of the drug is beneficial to maintain the resting heart rate at a target level of 50~60 beats/min. 3, statins: statins have become the basic treatment for secondary prevention of coronary heart disease, which can play the role of both lowering blood lipids and stabilizing plaque, and improving vascular endothelial cells, anti-intravascular inflammation, stabilizing plaque and not myocardial infarction, which is the key to prevent cardiovascular events. All patients with coronary artery disease should take it to reduce the level of low-density lipoprotein (LDL-C) to below 2.6 mmol/L. For very high-risk patients (such as patients with combined diabetes or acute coronary syndrome), lipid-regulating therapy with statins should be intensified to reduce LDL-C to below 1.8 mmol/L. 4, always have emergency drugs: patients have been diagnosed with coronary heart disease, must always have nitroglycerin around, once the acute attack of coronary heart disease, should be immediately sublingual. If one piece of nitroglycerin is not effective, take it again every 5 minutes, repeat this three times, if it is not effective, go to the hospital as soon as possible. 5, regular review: follow the doctor’s advice, regular and timely review, as far as possible to the hospital where you were hospitalized or the doctor in charge, the doctor will adjust the drugs for the patient’s own situation. Review items: 1, blood pressure, blood glucose (including glycated hemoglobin), blood lipids, liver and kidney function, coagulation function, etc.; 2, electrocardiogram, cardiac ultrasound, exercise plate, myocardial nuclear (can be considered when the elderly have poor exercise capacity); 3, troponin, coronary angiography or coronary CTA (can be considered when chest pain is recurrent).
