Coronary heart disease is hereditary diseases?

Coronary heart disease is genetic disease, is not a very prescribed concept, but at home and abroad large epidemiological study results showed that the incidence of coronary heart disease have obvious familial. One of the parents suffering from coronary heart disease, its prevalence rate for children with normal parents of two times their parents are suffering from coronary heart disease, its prevalence rate for children of parents four times the normal; if both parents at a young age are suffering from coronary heart disease , His close relatives the chance to get sick five times in this situation without the family. Study the pathogenesis, it is not very clear, and may be related to the following factors: (1) autosomal dominant genetic caused by the family of hyperlipidemia is that these family members susceptible to the disease one of the reasons (2) some Coronary heart disease risk factors, such as hypertension, diabetes, obesity characteristics, character traits, such as severance-tendency, that is, family members susceptible to the disease can not be ignored important factors (3) the same family in the impact of adverse living habits, such as the common High fat, high-calorie, high-salt diet, smoking parents smoking or passive smoking caused their children's bad habits, etc., can cause coronary heart disease tend to the family. More scholars believe that the family of coronary heart disease is clearly the characteristics of a variety of factors is the result. Genetic factors are internal reasons, it only and other risk factors combined, can increase the incidence of coronary heart disease.
