I believe that everyone has encountered people around them due to sudden cardiovascular infarction and suddenly passed away, a lot of people also know that this disease is caused by blood vessels are blocked, often in the first time to hear this kind of thing for their own have been worried about, but with the day by day, this kind of worry disappeared without a trace, so in order to avoid this kind of thing happen to themselves, do it both very easy and very difficult. The so-called cardiovascular stenosis refers to the heart on the coronary artery narrowing, in fact, is caused by coronary atherosclerosis, when the narrowing to a certain extent is to lead to myocardial ischemia is coronary heart disease. Then usually what we should do to be able to prevent the formation of cardiovascular stenosis? 1, dietary regulation: reasonable diet, do not favor food, should not be excessive. To control high cholesterol, high fat food, eat more vegetarian. At the same time to control the total calorie intake, limit weight gain. Usually pay attention to low-salt and low-fat diet, eat less sweets, eat less too oily food such as fatty meat, animal offal, egg yolks, which should be eaten sparingly, to limit the intake of trans fatty acids. Eat more vegetables and high quality protein, such as fish, shrimp, lean meat, soy products. 2, exercise regulation: increase the amount of exercise, walk at least 10,000 steps a day, at least 2 times a week of moderate intensity for more than 30 minutes of exercise, the key is to be persistent and gradual. This will help reduce blood lipid levels and keep you healthy and happy. 3, lifestyle regulation: quit smoking, quit drinking, live a regular life, avoid excessive tension; keep enough sleep, pay attention to the combination of work and rest. 4.Psychological regulation: maintain a relaxed mood, eliminate tension and anxiety, and be calm and peaceful. Coronary heart disease patients are often short-tempered, easy to get angry and offend others. Must often remind themselves to be calm and peaceful, increase patience, and enhance their ability to recover. 5, active prevention and treatment of chronic diseases in old age: such as hypertension, hyperlipidemia, diabetes, etc., these diseases are closely related to cardiovascular stenosis. Many people think that only when they are old, blood vessels will have problems. But do not know, from the age of 30 years later, our blood vessels have more and more problems, and the rate of hardening and the emergence of plaque greatly increased. When the blood vessels are mildly narrowed, the human body basically does not feel anything, when the narrowing is aggravated or when a heart attack occurs, the human body will have a bad feeling. Sometimes it is difficult to distinguish between the symptoms, coupled with the modern people live more and more tired, eat more and more unhealthy, exercise less and less, unknowingly accelerated the aging and damage of blood vessels, it is difficult to distinguish between the serious and the serious, so with cardiovascular risk factors of the population if the winter chest tightness, chest pain, it is recommended that the early diagnosis and treatment. In short, to prevent the occurrence of coronary heart disease to establish a good lifestyle is the most critical, good habits need to be long-term persistence, but unfortunately, many people do not know enough and can not be persistent. In addition, diabetes, high blood pressure, high uric acid, high blood fat and other problems occur, must take timely intervention and treatment measures, as far as possible to remove the disease factors that trigger the occurrence of atherosclerosis.
