I wonder: What kind of person easy to get coronary heart disease?

Answer: a combination of factors of coronary heart disease is the result of long-term. Epidemiological and laboratory studies have shown that high blood cholesterol, high blood pressure and smoking is the major risk factors of coronary heart disease, known as a major risk factor. Respectively one, two, three main risk factors, their coronary heart disease morbidity and mortality and the absence of these factors was compared to the second, fourth, eight-fold increase. Control of certain factors, the incidence of coronary heart disease and a corresponding decline in mortality. In addition, physical activity is too small, lack of physical exercise, overweight, diabetes, mental stress, A-type personality and family history of coronary heart disease, can affect the incidence of coronary heart disease and early age of onset. As a result of these factors are secondary risk factors

Second doubt: mental and physical suffering from coronary heart disease have a difference? Answer: is generally believed that mental suffering from coronary heart disease than manual workers is high, but the findings do not correspond exactly. Mental sit-time, lack of physical activity, prevalence rate is about 2-4 times that of manual workers. This is because stress can cause neuro-endocrine dysfunction, blood catecholamine, glucocorticoid levels, high blood pressure, can also be caused by lipid metabolism disorders, elevated blood cholesterol levels periodically, and further affect the clotting mechanism, and increased platelet aggregation endothelial injury. Mental stress and fatigue is also lazy exercise. Instead, insist on participating in physical training of the mental, coronary heart disease prevalence rate decreased significantly.

■ doubts III: Why do fat people susceptible to coronary heart disease? Answer: obesity a higher incidence of coronary heart disease, especially in the short term to get fat or a higher incidence of extreme obesity. Because of excessive weight gain, heart and blood pressure increased load. High-calorie food intake habits, so that blood lipids, blood pressure increased, the formation of coronary atherosclerosis and to increase. After the physical activity to reduce obesity, prevented coronary atherosclerotic lesions formation of collateral circulation. However, if we do not consider age or with hypertension, hyperlipidemia, diabetes and other disorders, obesity can not be a true risk factor.

four puzzled: why smoking can cause and increase coronary heart disease? Answer: The mortality rate of coronary heart disease and smoking was a significant positive correlation of adult smokers started before an even higher degree of hazard. Our data indicate that a large number of smokers than non-smokers a high incidence of coronary heart disease 2.6 times more than the high incidence of angina for more than 3.6 times. Smoke a cigarette containing 40 mg of tar, nicotine 3 mg, 30 mg carbon monoxide, the three substances are absorbed into the bloodstream, the nicotine directly stimulate the vasomotor center, and to stimulate epinephrine and norepinephrine release, causing heart rate to speed up the , peripheral vasoconstriction, increased blood pressure, followed by vascular endothelial injury, but also increase blood cholesterol levels. So that the concentration of carbon monoxide decreased oxygen, inadequate oxygen supply organizations, arterial wall edema, endothelial damage, lipid infiltration of the vessel wall to promote atherosclerosis. People who have had coronary heart disease, smoking may accelerate the progress of their condition and cause a heart attack. When a large number of smokers due to hypoxia and increased cardiac excitability, can induce serious arrhythmias such as ventricular fibrillation, becoming one of the reasons for sudden death.

■ doubts Five: alcohol coronary heart disease can trigger it? Answer: a large number of alcohol can increase the burden on the heart and liver, a large number of alcohol direct myocardial damage, resulting in myocardial energy metabolism, and inhibit lipoprotein lipase to the liver synthesis of pre-β lipoprotein, triglyceride increased to enable and promote atherosclerosis Atherosclerosis. However, sustained a small amount of alcohol there are hypolipidemic role, which may protect the cardiovascular system, inhibiting the formation of atherosclerosis. Quantitative study showed that alcohol consumption: the size, regardless of age, alcohol consumption per month when more than 1.5 kilograms, coronary heart disease mortality increased by 2 times. Drinking a small amount of high-quality white wine (about 0.5 kilograms per month total), can be conducive to the prevention of coronary heart disease.

■ Six puzzled: Why focus on the prevention of coronary heart disease? Answer: coronary heart disease is an ancient disease, the incidence in recent years, exacerbated in the world. China's 40-year-old prevalence rate of coronary heart disease for more than 4% -7%, the incidence of myocardial infarction were 39.7-64 / 100,000, the death rate for 20.7-41.9/10 million. The basic cause of coronary heart disease is atherosclerosis. Onset of atherosclerosis secretive, incidence of childhood can be. Shown to be of vascular stenosis, the symptoms of insufficient blood supply, the more severe fibrosis has been associated with calcification, ulceration of the advanced lesions, it is difficult to modern medical means to rehabilitation. Experimental studies have proved that early atherosclerotic lesions by risk factors could reduce atherosclerotic plaque regression. Certain drugs on the occurrence of atherosclerosis, the development may have a certain extent, but the complexity of advanced disease have atherosclerotic plaque is ineffective. Thus, the present against atherosclerosis, coronary heart disease must focus on prevention, adhere to the principle of prevention.

■ doubts Seven: fish, tea, qigong can do to prevent coronary heart disease? Answer: eat fish may be the prevention of coronary heart disease. Scientists found that fish oil used to be the N-3 fatty acid can lower blood triglyceride and cholesterol, high density lipoprotein increased slightly, to reduce low-density lipoprotein synthesis in liver, it can actively prevent atherosclerosis and coronary heart disease occurs, N-3 fatty acid also inhibit the role of vascular inflammatory response, thereby delaying the formation of atherosclerosis, in addition to inhibiting platelet release, aggregation. Tea on the prevention of coronary heart disease there are good results. Tea has anti-coagulation and fibrinolysis to promote the role of the polyphenols contained in tea may improve the microvascular permeability of the wall, can effectively enhance the cardiac and vascular wall elasticity and resistance, can reduce blood levels of medium-sized fat and cholesterol. Tea Vitamin C and vitamin P, also has to improve microvascular function and promote the role of cholesterol excluded. Caffeine and theophylline, may be directly excited the heart, coronary artery to expand and improve the function of the heart itself. Qigong practice is a better approach to the prevention of coronary heart disease. Qigong transfer income from the start, improved myocardial ischemia and hypoxia, to alleviate the burden on the heart. Emotional impact on coronary heart disease, and qigong requirements into the quiet, relaxed, the heart will be, God clearance, open-minded, happy optimism, just to help patients with emotional stability.
