In recent years, more and more young people are found to be suffering from coronary heart disease, and frequent myocardial infarction, and even sudden death events, coronary heart disease has no longer become the “old age disease” of the spokesman. So, what kind of people will be prone to care about the disease? What are the risk factors of coronary heart disease? How should we prevent the occurrence of coronary heart disease? I. Risk factors for coronary heart disease: 1. Gender: menopausal women and all adult men: women rarely suffer from serious coronary heart disease before menopause because of the cardiovascular protective effect of estrogen, while after menopause, the body’s estrogen secretion gradually decreases, blood viscosity increases, so that the chance of coronary heart disease increases significantly. And men as a high prevalence of coronary heart disease, over 18 years old are likely to suffer from coronary heart disease. 2, age: coronary atherosclerotic heart disease, which is a kind of cardiovascular degenerative changes, with the growth of age, atherosclerosis will gradually aggravate, age is a crucial factor, age can not be changed, but atherosclerosis can slow down the process through diet, drugs, exercise and other regimen. 3, genetic factors: the specific mechanism is still unclear. Studies have shown that patients with a family history of early-onset coronary heart disease (<45 years old) have a high incidence of coronary heart disease. Another genetic disease worthy of attention is familial hypercholesterolemia, some elderly people are very thin but suffer from severe coronary heart disease, no other risk factors, but the blood cholesterol and LDL are very high, and their children are also generally very high, also known as familial hypercholesterolemia, need early detection and treatment. 4, smoking: this is the more significant risk factors for early onset coronary heart disease. Nicotine induces repeated contraction of the vascular endothelium, leading to endothelial damage, greatly accelerating the process of atherosclerosis, is a controllable risk factor for coronary heart disease. 5, alcohol consumption: some of the current well-known cardiovascular experts believe that the relationship between alcohol consumption and coronary heart disease mortality is V-shaped, that is, when a small amount of alcohol consumption coronary heart disease mortality is decreasing trend, while a large amount of alcohol consumption makes coronary heart disease mortality is increasing trend. People drink a small amount of alcohol in daily life is not inappropriate, the key is to prevent a large amount of alcohol and long-term excessive alcohol consumption. 6, mental stress: long-term high workload and easily excited and angry temper, is also a risk factor for coronary heart disease. If you stay up late for a long time, it is recommended that you must pay great attention to it. 7, "three high": that is, hyperlipidemia, hypertension, hyperglycemia (diabetes), which is known to be a risk factor for coronary heart disease, their harm is slow, comprehensive, often takes decades to develop, so it can not attract the attention of some patients, but once the disease, are complex, multi-system problematic diseases, such as coronary heart disease Combined renal insufficiency, cerebral atherosclerosis, peripheral atherosclerosis, etc. 8, obesity: especially young people, metabolic syndrome as the centralized representative, manifested as abdominal obesity, hypertension, hyperlipidemia, abnormal glucose tolerance, etc., mainly in the diet, lifestyle, weight loss is an effective means to avoid this risk factor. 9, bad lifestyle: sedentary, lack of exercise. Sedentary or affect the fat metabolism, significantly reducing the activity of lipid prion lipase. And this enzyme can break down blood lipid circulation and give muscle energy. The reduction of this enzyme activity makes the fat and triglyceride content in the blood rise, increasing the risk of coronary heart disease, therefore, abandoning a bad lifestyle is a major means of preventing coronary heart disease. 10, metabolic abnormalities in the body and some pathogenic microbial infections: including hyperhomocysteinemia, viral, chlamydial infections and other factors. Second, the prevention of coronary heart disease 1, irreversible risk factors such as gender, age, genetic factors, etc., which can not be changed by each person, but we understand such risk factors, can correctly assess their risk of coronary heart disease, and decide the future prevention strategy. 2, the control of reversible risk factors, we should be sure to quit smoking and limit alcohol consumption, alcohol control in white wine within 1 two / day, wine in 150ml, beer in 300ml or less; to develop a scientific and reasonable routine, avoid excessive mental tension, overwork, avoid staying up late, to learn to relax themselves, relaxation; reasonable control of blood lipids, blood pressure and blood glucose levels, early detection and early treatment, not full of care, not too optimistic; pay attention to the control of weight, blood pressure and blood glucose levels, early detection and treatment, not full of care. Pay attention to weight control, keep the body mass index between 21-25 (BMI calculation: weight kg/elevated meters, keep your mouth shut, open your legs, eat lightly, adhere to exercise, walk more than 3,000 meters a day, at least three times a week, and adjust the walking speed in combination with your physical condition; regularly perform physical examinations, find abnormal biochemical indicators in the body, such as blood lipids, blood sugar, uric acid, homocysteine, etc. The abnormalities of hemiphosphoric acid and other abnormalities should be promptly consulted, the discovery of Helicobacter pylori infection should be promptly treated, and when the immune system is low with frequent colds, it is necessary to promptly seek Chinese medicine to avoid microbial induced coronary heart disease.
