Once summer is over, the heat is about to set in. Patients with coronary heart disease usually feel tightness in the chest and breathlessness during the hot summer. How can we get through the summer in peace? Here are a few tricks to teach you: 1. Three and a half minutes to keep your life safe. “Three and a half minutes” means that when you get up at night and early in the morning after waking up, you should continue to lie down for half a minute, then sit in bed for half a minute, then legs down along the edge of the bed for half a minute, and then finally move down to the ground. Why do we need to emphasize the “three and a half minutes” for cardiovascular and cerebrovascular patients? Because clinically, cerebral thrombosis, cerebral hemorrhage, sudden cardiac death and other diseases often occur at night. 24-hour ambulatory ECG monitoring shows that many patients’ hearts beat smoothly throughout the day, but there are only a few big fluctuations at night, and most of them are at night when the patients get up to go to the toilet. Even for normal people, care should be taken to avoid fainting caused by sudden changes in body position. 2, the diet is the basis, red, yellow, green, white and black. Red refers to red wine, drink 50-100 ml per day to help prevent coronary heart disease; yellow refers to yellow vegetables, such as carrots, sweet potatoes, tomatoes, etc., rich in carotene, can reduce the degree of atherosclerosis; green refers to green leafy vegetables; white refers to oat flour, oatmeal, consume 50 grams per day, can effectively reduce blood triglycerides and cholesterol content; black refers to black fungus, 5-10 grams per day, to reduce blood viscosity and cholesterol with obvious effect. In addition, we should also do: coarse and fine, not sweet and not salty, three, four, five meals, seven or eight minutes full. There are coarse and fine, that is, to match coarse and fine grains, complementary nutrition, eat three or four times a week coarse grains, which is good for health; not sweet and not salty means do not eat too sweet or too salty, eat about 6 grams of salt a day moderate; three, four, five meals refers to the number of meals eaten every day, the average person is three or four meals a day, how to arrange the “five meals”? Breakfast and lunch in the middle plus a meal snack, four or five in the afternoon to eat a meal, dinner to eat later, so less food more meals, the total amount of the same; seven or eight full refers to eat not too full, seven or eight full can be. 3, timely hydration, green tea is preferred. Cardiovascular patients morbidity and mortality, the cause and excessive sweating, not timely drinking water, blood concentration. Due to the different amount of sweating, the daily water requirements are also different. The standard to 1500 ml of urine per day, as long as there is about 1500 ml of urine per day that is enough water in the human body. 4, do not drink ice water to prevent sudden cardiac arrest. Drinking more than 3 cups of ice water, almost all people have changes in the electrocardiogram. As a short period of time to drink a large number of cold drinks induced angina, acute myocardial infarction, the clinical has been seen time and again, so do not be cautious. 5, a half-hour nap, coronary heart less than 30%. Research studies show that the daily nap half an hour than those who do not sleep coronary heart disease mortality rate of 30% less. The reason for this and nap when the blood pressure drops, the heart rate slows down, and the peak of blood pressure during the day appears a period of low. 6, emotional stability to prevent angina. According to the survey, the acute myocardial infarction attack triggers the first proportion of emotional excitement. Prevention of angina pectoris, myocardial infarction is the most important health care method is emotional stability, calm and quiet. 7, “devil’s time” to be cautious. Wake up in the morning, you face the “devil’s time” section – 6-9 am. During this time, heart disease, stroke, bronchitis, emphysema, asthma and even cancer and other diseases, such as myocardial ischemia, the peak of the onset of 7-8 a.m.; arrhythmias occur most frequently from 6-9 a.m.. In addition, the World Health Organization has investigated 4769 cases of myocardial infarction, 28% of which occurred between 6 and 10 am. While promoting the above healthy lifestyle habits, it is also very important for patients with coronary heart disease to undergo drug prevention and treatment.
