Some people because their parents have coronary heart disease or myocardial infarction, worry that they and their children will also get this disease, clinic, ask me “doctor, this disease hereditary” patients abound. In fact, in real life, a few generations have coronary heart disease phenomenon exists, but this does not prove that coronary heart disease will be hereditary. Coronary heart disease genetic factors in the end accounted for how much weight for coronary heart disease is hereditary problem, can be described as a variety of opinions. Some people say that coronary heart disease has a certain degree of heredity, and that those with a family history have a higher prevalence than those without; others say that coronary heart disease is not hereditary, and that it is a lifestyle disease. I think the answers from both sides need to be combined. First of all, the hereditary factor of coronary heart disease cannot be completely denied, but there is a clear difference between coronary heart disease and what is usually called hereditary disease. It is true that those with a family history have a higher prevalence rate than those without, but it is often due to the fact that the family has been living together for a long time and has the same or similar living habits, such as eating a heavy diet, liking meat, not exercising, being withdrawn, and so on, which likewise shows that coronary heart disease is a lifestyle disease. Coronary heart disease and lifestyle habits are closely related Recognized causative factors of coronary heart disease are hypertension, hyperlipidemia, diabetes, obesity and so on. And these disease-causing factors and lifestyle habits have a great relationship. 1, hypertension: hypertension has family factors, but a large part of the causes of hypertension and smoking, alcoholism, impatience, as well as dietary salt intake is too much. 2.Obesity and hyperlipidemia: most of them are caused by excessive diet, irrational diet structure and lack of physical activity. 3, diabetes mellitus: itself has family factors, but such as attention to dieting, avoid overweight, can also make the possibility of reducing the incidence of diabetes mellitus, as long as the reasonable treatment, can significantly reduce its cardiovascular harm. Summarized, many coronary heart disease triggering factors are actually caused by bad habits, improve lifestyle habits can better prevent coronary heart disease and other diseases. Regardless of whether coronary heart disease is hereditary or not, prevention is the key to coronary heart disease will not be hereditary, coronary heart disease is hereditary disease, there is not a very clear concept, we are also very difficult to determine whether this disease will be hereditary, but there is a fact that: to do a good job of the relevant measures, you can still reduce the chances of the occurrence of coronary heart disease. So the question arises, how to do? With the improvement of living conditions, the incidence of obesity, high blood fat, high blood pressure, diabetes and other diseases has increased, which is worth noting. Because these are in fact the causative factors of coronary heart disease, and much higher than the genetic odds. To be well prevented, first of all, the daily diet to vegetable oil, vegetables and grain-based, less salt and sugar, a small amount of meat, eggs and dairy; appropriate physical activity, pay attention to the combination of work and rest; emotional stability, to avoid psychological problems brought about by the stress of life; and finally pay attention to the cessation of smoking and alcohol. In the smoking ranking, China is still at the top. Therefore, it can not be said that coronary heart disease and genetic factors have nothing to do with, and we do not need to be too nervous, worry, anxiety, negative emotions, on the contrary, harmful to health. Moreover, the prevention of coronary heart disease is completely self-control, deep understanding of the factors unfavorable to health, and gradually change, in order to make the possibility of coronary heart disease is reduced.
