The incidence of heart disease is higher in winter than in spring and fall, and the incidence of acute heart attack is significantly higher during the cold winter months, especially during continuous cold, rainy and windy weather. There is an association between winter and heart attack. Therefore, heart attack patients should pay special attention to the following issues in winter. Winter note one: never lift too heavy items, a common cause of heart attack induced by elderly coronary heart patients is to lift too heavy items, when lifting items are bound to bend over and hold the breath, which is similar to the impact of the whistling, circulatory system and forceful breath holding stool, easily induced myocardial infarction. Winter note two: many depressed patients are accompanied by heart disease, so the mood affects our own health, keep a calm, relaxed state of mind, to anything to be able to take it in stride. Winter attention three: heart disease patients should have at least three times a week serious physical exercise, each time not less than 20 minutes, but also should not exceed 50 minutes. At the end of the exercise to do some relaxation activities, should not immediately stop activities, and should not exercise immediately after bed rest, otherwise it is easy to cause dizziness, which is not good for the heart. Winter note four: do not bath in the case of a full meal or hunger, bath after a full meal, the skin surface blood vessels are hot water stimulation and expansion, more blood flow to the body surface, the abdominal blood supply is relatively reduced, will affect digestion and absorption; hunger bath easy to cause hypoglycemia, and even deficiency, fainting. Patients with more serious coronary heart disease should take a bath with the help of others. Winter attention five: to pay attention to climate change, low temperature, high winds, cloudy rain is one of the triggers of acute myocardial infarction. Under the influence of severe cold or strong cold air, the coronary arteries can spasm and secondary thrombosis and cause acute myocardial infarction. When the climate changes rapidly and the air pressure is low, patients with coronary heart disease will feel obvious discomfort. Therefore, whenever the climate is bad, patients with coronary heart disease and myocardial infarction should pay attention to keep warm or take appropriate medication for protection.
