In winter, the atmospheric pressure, wind speed and temperature difference in most areas of China are in a highly unbalanced state, and patients with coronary heart disease are less adaptable to weather changes, and the cold winter has a greater impact on patients with coronary heart disease. The results of a foreign medical meteorological study show that 77% of patients with myocardial infarction and 55% of patients with other types of coronary heart disease are particularly sensitive to climate change, especially sudden drops in temperature, and the incidence of myocardial infarction is significantly higher. Furthermore, the fact that the incidence of coronary heart disease is significantly higher in northerners than in southerners indicates that cold has an effect on the onset of coronary heart disease. Moreover, cold season is often prone to colds and bronchitis, which are often the main triggers of angina and myocardial infarction. Why does cold stimulation increase the number of coronary heart disease attacks? This is because low temperature stimulation tends to make the sympathetic nerve excited, blood pressure increased, heart rate continues to accelerate, thus increasing myocardial oxygen consumption. Low temperature stimulation can cause spasm and contraction of small blood vessels on the surface of the body, while the systolic and diastolic functions of arterial vessels also become impaired, resulting in slow blood flow and failure to complete normal circulatory functions. In order to compensate for the function, the heart muscle must work harder to maintain the normal blood flow rate, which inevitably increases the burden on the heart, while cold stimulation causes vasospasm and contraction, and blood viscosity also increases significantly when blood flow slows down. This is also a factor that promotes spasmodic constriction of the coronary arteries. Coronary artery spasm, which reduces coronary blood flow, and continuous vasospasm can lead to thrombosis and aggravate coronary heart disease. In addition, the cold climate causes changes in people’s lifestyle, such as dietary changes, reduced activity and low mood, which makes blood circulation slow and venous thrombosis easy to form, thus increasing the risk of myocardial infarction and sudden cardiac death. Therefore, in the cold winter, patients must do a good job of self-care: 1, must do to prevent cold and keep warm, especially the patient’s face and extremities warm. In the cold wave and heavy wind and snow bad weather, should reduce the time to go out and work outdoors, when going out should wear a good mask, hat and cotton clothes. 2.
Physical activity is not suitable for patients with more frequent episodes of angina, especially not morning exercise, do not carry out strenuous activities in the cold climate, . Insist on physical exercise within your ability, such as outdoor walking, taijiquan, qigong, etc.. But in case of sudden cold, snowstorm, wind and other weather changes, to stay indoors, according to temperature changes, timely change of clothes and bedding, pay attention to warmth; 3, psychological balance, to avoid great joy and grief. Work and rest in moderation, as little as possible to participate in long-distance travel, and develop good habits of life and living. To ensure adequate sleep and rest, can reduce the burden on the heart, to avoid attacks, frequent attacks of angina pectoris patients, should reduce the room activities, so as not to emotional excitement, increase myocardial oxygen consumption, aggravate the disease. 4, avoid triggers, to actively prevent and control colds, bronchitis and other upper respiratory tract infections, so as not to increase the burden on the heart due to inflammation of the lungs or fever, and advocate the use of warm water baths to improve the skin’s ability to resist cold. 5.Check your body regularly and follow the doctor’s instructions to do so.
In addition to insist on taking the common medications for coronary heart disease, you should also have a health care box, oxygen and other emergency drugs; when chest tightness and chest pain occur, you should promptly use the emergency drugs that come with your life and go to the hospital for examination and treatment at the same time. In addition, you can also take appropriate tonic to strengthen the body and prevent the occurrence of coronary heart disease. According to Chinese medicine, winter tonic is most suitable from the beginning of winter to the beginning of spring. The tonic should not be excessive, but should be different from person to person, mainly “food tonic”. Qi deficiency Yang deficiency, can choose some sweet warm tonic function of mutton, chicken, rabbit, cinnamon and soybean products; Yin deficiency internal heat, can be appropriate to choose some of the deficiency, in addition to heat, and viscera, the function of water, duck, goose meat and lily, yam, glutinous rice and mung beans, etc.. Ginger, onions, etc. is a rare winter tonic, often eat ginger has traditionally been regarded as health care, especially one of the key to a strong cardiovascular system. Ginger is rich in curcumin, which has a stimulating effect on the heart and blood vessels and can make the blood vessels dilate, thus making the veins flow smoothly and supply normal. Onions contain substances such as flavonoids, which can lower blood pressure, prevent thrombosis and atherosclerosis, and are the ideal food to prevent cardiovascular disease. It is also important to pay attention to eating more fruits and fresh vegetables to replenish the appropriate vitamins.
