Myocardial ischemic angina often occurs when myocardial oxygen consumption increases due to exertion, emotional excitement or other factors, and the pain often radiates to the left shoulder, cervical pharynx or jaw, and is relieved within a few minutes by rest or nitroglycerin. Temporary ST-segment changes or T-wave changes are often seen on the ECG during an attack of myocardial ischemia angina, and coronary artery lumen narrowing is seen on coronary angiography. In addition to insisting on medication, home care is also an important treatment for cardiovascular disease, which is briefly described as follows: 1. It is better to get up slowly than urgently. 2, wash with warm water, especially in winter Sudden cold water stimulation can cause blood pressure to rise due to vasoconstriction. Cold stimulation is also a common cause of myocardial ischemia angina attack. 3, do not force when defecating Do not be anxious to empty the bowels and force to hold the breath, too much force can cause a sudden rise in blood pressure and induce accidents. Patients should learn to relax themselves during defecation and exert themselves gently. Do not stand up suddenly after defecation. 4, regular rest and relaxation to ensure 7-8 hours of sleep. Every day after lunch half an hour to an hour nap, even if not sleep, take a nap, adhere to the lunch break to help maintain stable blood pressure, especially necessary for poor heart function. 5, relieve tension When the psychological tension, do not pace around the room, it is best to lie down for a while or simply lift the legs slightly, sit quietly for 15 to 20 minutes. 6, sleep with the legs of the bed slightly higher Where the blood pressure is normal or high people (especially those who sleep less at night), to sleep with the legs of the bed slightly higher 7 to 10 cm. This helps to fall asleep quickly and improves the quality of sleep. A sensation of blood flowing to the head may occur at first, and to alleviate this sensation a higher pillow can be used. It is important to keep the legs and lower extremities slightly above the level of the heart. However, people with blood pressure below 100/60mmHg should not do this. 7, appropriate exercise cardiovascular patients appropriate exercise can improve the condition, but the exercise program should be soft, such as tai chi, health exercises, walking, jogging, etc., the time should not be long, should not exceed half an hour. Exercise intensity to not more than 120 beats per minute heart rate is appropriate; if during exercise panic, chest tightness or dizziness, should be immediately suspended. 8, diet Coronary artery disease myocardial ischemia people mostly have hypertension, high blood pressure or diabetes and other predisposing factors, so in terms of diet coronary artery disease myocardial ischemia people should limit total calories, reduce fat, cholesterol intake, eat less high fat, high cholesterol, high calorie food. Animal offal (such as loin, liver, pig brain), ribs, pork, as well as egg yolk, fish without scales, etc., contain high cholesterol, should be eaten as little as possible; Western fast food, fried food, broth and food with many condiments should also be eaten less. Foods containing more fiber, such as vegetables and fruits, can be consumed more often. Fish is good for lowering blood lipids and can be eaten more often. Protein intake is not less than 1 gram per kilogram of body weight per day (can be obtained from lean meat, fish, eggs, milk and legumes). Eat more vegetable oils and less animal fats, and fresh vegetables are indispensable. Cook delicious, soft and rotten meals to facilitate digestion and absorption. Eat less or no fried, cold food, quit smoking and alcohol. People with high blood lipids and obesity should restrict high-fat and high-calorie foods appropriately. Those who do not have high blood lipids and have a thin physique do not need to restrict fat, but can eat more nutritious and easily digestible foods. Those who are more seriously ill with edema and low urination should strictly restrict salt. Patients with hypertension and heart failure should also limit salt intake and should not eat too salty. People with increased uric acid should limit the intake of soy products. 9, do not stand to eat Standing and eating while walking will add extra burden to the cardiovascular system. After that, do not immediately put into stressful activities either. 10.Stay away from crowded and noisy environment Go to the street. Try not to take a crowded bus. Overcrowding and noise can cause blood pressure to rise and heart rate to accelerate. If the distance is not far, it is best to walk. Go out with some generous time to avoid rushing.
