The common cardiovascular diseases (atherosclerosis, hypertension, coronary heart disease, cerebral infarction, diabetes, hyperlipidemia, gout) in the elderly have their common causes and triggers, so the preventive measures also have their consistency. The mental age of people is not the same as their actual age. Some people are not too old physiologically, but they enter old age prematurely because of their depressed thinking and dull lifestyle. On the contrary, some people are already in their old age, but they have an active mind, cheerful personality, laughing and smiling, compared with young adults. Good mental state, like physical health, can be obtained through their own continuous efforts, especially the elderly, to learn to create their own fun, optimism makes people young, make people live longer, to enjoy the “sunset infinite good”, do not care about “just near dusk”. How to maintain a good state of mind, the following aspects can be referred to: A, a positive attitude towards life: do not want fame and fortune, not to compare, love life, treat life well. B, arrange family life: to be good at listening to their children’s views in order to fill the generation gap, to deal with the relationship between the mother-in-law and daughter-in-law, understanding that the daughter-in-law is also a delicate daughter in her mother’s house, the son-in-law is also an only child. The love of the elderly couple is the core of the physical and mental happiness of the elderly, to care for each other, help and considerate. C. Adapt to life events. There are nine out of ten unpleasant things in the life of the elderly. The elderly must learn to adapt to life, face reality, and learn to look at and deal with it from different sides and different perspectives in two ways. There are two ways: one is to find someone to vent, to relatives, to friends, to classmates to confide in, even if it does not help, will be cathartic and reduce the pain. The second is to go out, participate in outside activities, go to the park, shopping malls, rather than a person bored at home. After the adjustment of the mind will be conducive to nutritional balance, prevention of disease and promote recovery from disease. ②Create good habits Good habits are essential for the prevention of cardiovascular diseases. Preferring fatty food and eating salty and sweet food are not good for health. The elderly should have a low-fat, low-salt, low-calorie diet with protein, vitamins, trace elements and coarse fiber foods. Regarding the quality and quantity of the diet, the quality is based on the principle of variety and balance. Japanese experts advocate 30 kinds of food per day, and the recent healthy diet guidelines issued by China suggest 27 kinds of food per day, in fact, more than 20 kinds can be consumed. Regarding the quantity of meals, the main contradiction today is the excessive amount of food and excess calories. It has long been proven that obese children are 3-5 times more likely to suffer from cardiovascular disease as adults than children of normal weight. Massachusetts Institute of Technology research results show that: proper starvation can extend the natural life span of mammals by at least 50%. For this reason, it is recommended to eat less and promote the body often in a state of mild hunger, to slow down the aging process, to extend life, have a positive significance. There are many components within tobacco and alcohol that tend to make cardiovascular spasm and induce cardiovascular disease. ③Supplement vitamins and water Vitamin C can counteract the toxicity of blood lipids and has the effect of delaying atherosclerosis and increasing the toughness of blood vessel walls. Folic acid and B vitamins can both resist atherosclerosis and partially restore the elasticity of blood vessel walls, so that the reversal of lesions that have already occurred can occur. Therefore, people should take moderate amounts of vitamin C, folic acid, and multivitamins starting from middle age. It is best to take them in food. Drinking more water can start the body cells; secondly, drinking more water can slow down the aging. In particular, drink 500ml of water in the morning to reduce blood viscosity, promote blood circulation, increase urine volume, promote the excretion of metabolites in the body, but also to cleanse the residual waste in the stomach and intestines, long-term adherence can prolong life. ④ Regular physical checkups Older adults should have regular annual physical checkups and have their blood lipids and blood sugar concentrations tested. Hypertension and hypotension are both common in the elderly, so when measuring not only sitting blood pressure, but also lying blood pressure should be measured. Method: Measure blood pressure after lying down for 10 minutes, and then measure blood pressure once each in upright position for 1, 3 and 5 minutes. If systolic blood pressure decreases ≥20 mmHg or diastolic blood pressure ≥10 mmHg at any time when upright, it is called postural hypotension. The elderly are prone to postprandial hypotension within 2 hours after meal, which is obvious after breakfast, followed by Chinese meal, and the lightest after dinner. If postprandial weakness, dizziness and other ischemic symptoms are present, preprandial and postprandial blood pressure should be measured. If you have been ill for many years, often seek medical treatment, and are hospitalized annually or several times, regular physical examination is not very meaningful.
