With the improvement of living standard and lifestyle changes, the prevalence and death rate of coronary heart disease are gradually increasing, and it has become one of the important “killers” threatening human health and life. As a slow progressing chronic disease, good treatment, prevention and home care is one of the important means to improve the quality of life for patients with coronary heart disease. Do the following points, I believe that the prevention and treatment of coronary heart disease will be of great help. 1, mental health: coronary heart disease is generally sudden onset, coupled with the symptoms of chest tightness and chest pain manifested by coronary heart disease make most patients fear of coronary heart disease, anxiety and even depression, in addition to the guidance of doctors to patients, the role of family members to patients should not be ignored. Family members should be concerned about the patient to understand, can use listening, guidance, comfort, encouragement, help and other methods, so that patients have confidence in the control of the disease. 2, reasonable diet: reasonable diet for patients with coronary heart disease has a great role in controlling the development of the disease. For patients with coronary heart disease, it is recommended to eat more light and nutritious, and low fat, low salt, low sugar, high vitamin, high fiber, high protein food, such as milk, lean meat, fish, soy products, oats, buckwheat, mushrooms, fungus, kelp and various vegetables. Reduce the consumption of high-fat, high-sugar, high-salt foods, such as fatty meat, egg yolk, animal offal, cream, etc.. At the same time strong tea, coffee, cola and other beverages consumed less, you can eat more bananas and other to prevent constipation, less myocardial infarction triggers. 3, regular life: a relaxed and harmonious living environment is also very important for patients with coronary heart disease, patients should live in an environment that makes the body and mind feel happy, avoid excessive tension, excitement, sadness and other emotions. At the same time to ensure adequate sleep, do not overwork, stay up late. Move slowly when getting up, and move your limbs a little before getting up. Do not be hungry or overeat, and avoid extreme cold or hot environments. Have regular bowel movements and do not hold your breath during bowel movements. 4, follow the instructions to take medication: leave the hospital at home patients should mainly follow the doctor’s instructions to take medication regularly. Many patients in the disease after stabilization without the consent of the doctor arbitrarily reduce medication, resulting in the recurrence of symptoms and even heart attack. For some drugs such as betalactam, you should also follow the doctor’s instructions to monitor blood pressure and heart rate to prevent overdose. 5, appropriate exercise: some patients believe that exercise can trigger a coronary attack, in fact, appropriate and reasonable exercise can improve the ability of the myocardium to use oxygen and reduce myocardial oxygen consumption. Of course, patients should choose the appropriate type of exercise, such as jogging, walking, etc.. And the intensity and time of exercise should be controlled, and should be gradual and avoid strain. Before exercise, it is best to consult a doctor. 6, master first aid: coronary heart disease usually develops suddenly, so some first aid drugs such as nitroglycerin, quick-acting heart pills, etc. should be carried with you, the home should always have oxygen, blood pressure meter and other medical equipment. Patients and their families should have a brief grasp of blood pressure measurement. Once the patient has chest tightness and chest pain, he should take nitroglycerin 0.5mg under the tongue or 5mg of cardiac pain, and rest in bed with oxygen. If the condition does not improve, should promptly seek medical attention. 7, regular review: regular review is very important for patients with coronary heart disease, doctors through electrocardiogram, cardiac ultrasound, blood lipids and other tests to understand the patient’s condition and adjust the drugs. Patients can have regular coronary CT or coronary angiography to understand the coronary artery lesions and guide the next treatment. When the coronary arteries are severely blocked, patients are prone to myocardial infarction, which can be life-threatening in dangerous cases. In this case, depending on the specific situation, stent intervention or coronary artery bypass surgery is required. In conclusion, only with knowledge about coronary artery disease can we change patients’ bad habits, improve self-care, reduce disease recurrence, reduce the number of hospitalizations, reduce the burden on family and society, and improve our quality of life.
