Autumn and winter are the seasons with frequent cardiovascular and cerebrovascular diseases. When the human body is stimulated by cold air, it often leads to sympathetic nerve excitement, high blood pressure, thrombosis and stroke. We should pay attention to the treatment of primary diseases such as hypertension, and pay attention to aura symptoms such as sudden dizziness and severe headache. Cold can also cause coronary artery spasm, which directly affects the blood supply of the heart itself and induces angina pectoris or myocardial infarction. Therefore, for patients with cardiovascular diseases, although autumn is not as easy to cause disease recurrence as winter, it is also very dangerous to ignore the seasonal characteristics of autumn. Everything grows regularly, which can be described as "hidden in spring, summer, autumn and winter". According to the theory of traditional Chinese medicine, "Yang is nourished in spring and summer, and Yin is nourished in autumn and winter". Maintain the yin in the body in autumn and winter. The climate is getting cold, that is, when the yang in the human body converges and the yin essence hides inside. Therefore, it is necessary to raise yin essence. In modern society, due to the widespread use of air conditioners, it is often difficult to feel and experience the gradual change of temperature and warmth immediately, and it is difficult for people not to catch a cold after warming, so colds are generally more common. For young and healthy people, it may not cause a big problem, but if patients with cardiovascular diseases are also careless in this respect, it will easily lead to the original cardiovascular diseases such as coronary heart disease, hypertension, cardiac insufficiency, arrhythmia, pulmonary heart disease and so on. Therefore, patients with cardiovascular diseases should first pay attention to the climate change in autumn and winter, which can be started from two aspects. First, we should have a full understanding of our own diseases, avoid underestimating our "enemies", "refuel" our bodies when necessary, and adjust and supplement them in time. Second, we should pay attention to and understand our own situation. See a doctor as soon as possible, and don't be lazy and lucky in this respect, otherwise you will lose big because of small. Third, we should reduce the frequency of alternating cold and warm, especially from warm environment to cold environment. In addition, the dry climate in autumn and winter is the frequent season for various respiratory diseases and various respiratory infections. Allergic diseases are also the cause of cardiovascular diseases. For example, viral myocarditis is often caused by upper respiratory tract infection, and cor pulmonale is caused by long-term chronic respiratory diseases (such as chronic bronchitis, allergic asthma, emphysema, etc.). Therefore, the prevention and treatment of cardiovascular diseases are very important for patients. Patients with cardiovascular diseases should pay attention to the treatment of primary diseases in autumn and winter, such as coronary heart disease, hypertensive heart disease, rheumatic heart disease and pulmonary heart disease. We should also pay attention to the following matters: First, Chinese medicine believes that the prevention of heart failure is the primary cause of heart failure. Patients with heart failure should pay special attention to infection because of their poor disease resistance. Second, patients with low immunity should avoid moderate physical activity or excessive exercise in late autumn to reduce the burden on the heart. Third, don't get too excited. Western medicine believes that emotional excitement will cause sympathetic nerve excitement, leading to increased burden on the heart. Traditional Chinese medicine believes that the heart governs the spirit, and internal injuries are important factors of cardiovascular diseases. Fourth, in terms of diet and health, Chinese medicine has the saying that "dryness dominates the autumn season". After entering the late autumn season, many people have the symptoms of "autumn dryness", which are manifested in different degrees of dry skin, dry throat and lips, nosebleed, dry cough with little phlegm, upset and constipation. Mild patients can be relieved by eating pears, honey, sesame and other foods that moisten the lungs, nourish yin and moisten dryness. If the above symptoms are serious, Chinese medicine is needed. Fifth, when arrhythmia occurs, such as atrial fibrillation and atrial flutter, it is necessary to treat drugs that cannot abuse the cardiovascular system as soon as possible. Medication should be strictly in accordance with the doctor's advice, because some drugs will inhibit myocardial contractility, such as propranolol, betaloc, reserpine, quinidine, verapamil, etc., and attention should be paid. Patients with cardiovascular and cerebrovascular diseases should insist on taking drugs to treat coronary heart disease or hypertension in autumn and winter, regularly check electrocardiogram and blood pressure, and actively prevent diseases that may aggravate the condition such as colds. On this basis, supplemented by Chinese medicine treatment can often get twice the result with half the effort. Traditional Chinese medicine theory and modern research believe that cardiovascular diseases are located in the heart vein, and the etiology comes down to liver-qi loss, spleen deficiency and phlegm turbidity, phlegm and blood stasis, and injury to the blood house. The methods of soothing the liver and strengthening the spleen, resolving phlegm and removing blood stasis, and promoting blood circulation and dredging collaterals can all achieve good curative effects.
