Why is it easier to cause coronary heart disease in summer?

Anger, smoking and drinking are the most taboo of coronary heart disease. The central nervous system of the human body commands everything. When you are excessively excited and nervous, especially when you are in great joy and great sorrow, the arterioles can contract abnormally due to the stress response of the central nervous system, leading to an increase in blood pressure, an accelerated heartbeat, enhanced myocardial contraction and ischemia and hypoxia, thus inducing angina pectoris or myocardial infarction. Coronary heart disease is an irreversible chronic disease. Once you wear this hat, you must be prepared for a long-term "battle." However, patients with coronary heart disease can also live with illness. The key is to pay attention to self-regulation in life on the basis of rational drug use. First, avoid getting angry and angry. The central nervous system of the human body commands everything. When people are excessively excited and nervous, especially when they are in great joy and great sorrow, due to the stress response of the central nervous system, arterioles can contract abnormally, leading to an increase in blood pressure, an accelerated heartbeat, enhanced myocardial contraction and ischemia and hypoxia, thus inducing angina pectoris or myocardial infarction. Second, avoid overload exercise. "Life lies in movement", but life lies in balance, which embodies the fundamental law of life movement. Proceeding from the objective reality of the elderly, exercise should be done according to one's ability, just right, combining static and dynamic, and balancing yin and yang to achieve the best point. If you go too far, you will lose your balance and go to the opposite side. Therefore, patients with coronary heart disease should not only insist on exercise, but also strictly master the word "degree" to balance blood supply and blood demand. Third, avoid dehydration. Some middle-aged and elderly people usually do not develop the habit of drinking water regularly. When they are thirsty and want to drink water, they have caused different degrees of "dehydration". About 70% of human blood is water. How can blood flow without water? Because the blood viscosity of the elderly, especially patients with coronary heart disease, has increased, when it reaches a certain level, there may be a tendency of blood coagulation, leading to ischemia or cardiovascular and cerebrovascular blockage, and in severe cases, it may cause myocardial infarction or stroke. Water can dilute blood and promote blood flow, so the elderly should develop the habit of drinking water regularly. It is best to drink boiled water half an hour before going to bed, waking up in the middle of the night and getting up in the morning. Fourth, avoid hypoxia. Generally speaking, except for outdoor activities or aerobic exercise, the amount of oxygen inhalation is in line with physiological needs, and oxygen inhalation stars are often insufficient at other times, and patients with coronary heart disease are prone to chest tightness and other symptoms. If the oxygen supply is insufficient for a long time, it will aggravate the degree of arteriosclerosis. So patients with coronary heart disease should always ventilate the living room environment. When you feel chest tightness or discomfort in the chest area, take a few deep breaths (that is, deep breaths) slowly immediately. When angina pectoris occurs, in addition to taking emergency medicine, you should inhale deeply immediately. Those who have oxygen cylinders at home can inhale oxygen for a few minutes, which can relieve angina pectoris and reduce myocardial cell death. Fifth, avoid hot and cold. In severe cold season, patients with coronary heart disease should not ignore the warmth of hands, head and face. Because these parts are cold, it will lead to peripheral vasoconstriction, rapid heartbeat or coronary artery spasm. In addition, cold can also increase the secretion of norepinephrine and raise blood pressure. Therefore, patients with coronary heart disease should wear masks, gloves and hats when going out in winter; Brush your teeth and wash your face with warm water in the morning; Don't soak your hands in cold water for a long time when washing clothes and vegetables. In the hot summer. The substantial increase of human blood circulation will excite sympathetic nerves, accelerate the heartbeat and increase the extra burden on the heart. Therefore, patients with coronary heart disease in severe winter or hot weather. Corresponding self-protection measures should be taken. Sixth, avoid alcohol and tobacco. Nicotine can increase "fibrinogen" in blood, which leads to blood viscosity and easy to cause blood coagulation and abnormal changes of blood vessels, so the incidence of coronary heart disease in smokers is three times higher than that in non-smokers. After quitting smoking, fibrinogen in the blood is greatly reduced, which can reduce the incidence of coronary heart disease. Seven, avoid oral hygiene. If the oral cavity is unsanitary or suffers from dental diseases such as periodontitis, Gram-positive bacilli and streptococcus in the oral cavity may enter the blood circulation, causing arteriolar spasm or thrombosis, leading to myocardial infarction. Therefore, patients with coronary heart disease should especially keep their mouths clean and prevent dental diseases. Eight, avoid being too full. Because when the stomach is full, it will directly oppress the heart, increase the burden on the heart, and also lead to cardiovascular spasm, even angina pectoris and acute myocardial infarction. Therefore, patients with coronary heart disease usually declare that they should eat less and eat more meals, especially when they can only eat seven or eight points for dinner. Attention should be paid to four preventive methods of coronary heart disease. Coronary heart disease is very harmful to human body, especially the heart, an important organ of human body. If it is serious, it may lead to life-threatening, so the most important thing is to prevent the occurrence of the disease. At this time, it is necessary to understand the prevention methods of coronary heart disease. First, quit smoking. Nicotine in tobacco can increase people's blood pressure, heartbeat, cardiac oxygen consumption, vasospasm, abnormal blood flow and platelet adhesion. Studies have shown that the probability of smoking men aged 30-50 suffering from coronary heart disease is three times higher than that of non-smokers, and smoking is also an important cause of angina pectoris and sudden death. Second, give up drinking. Ethanol is toxic to human heart, and excessive intake of ethanol will reduce myocardial contractility. For heart patients, alcoholism will not only increase the burden on the heart, but also lead to arrhythmia. Third, control weight. Weight control is also one of the prevention methods of coronary heart disease. Studies have shown that when a person's weight exceeds 10% of the standard weight, the risk of coronary heart disease will increase by 38%. Hypertensive patients with diabetes should actively control their weight, because once they are overweight, the probability of coronary heart disease will be 1 times higher than that of hypertensive patients without diabetes. Fourth, the diet structure. People's daily intake of fat should not exceed 30% of the total calories needed, and their daily intake of cholesterol should not exceed 300 mg. Eat more foods rich in vitamin C and less foods containing saturated fatty acids and high cholesterol.
