Congenital heart disease to find out the reasons for the seven

Babies born in China each year, about 7 ‰ to 11 ‰ for congenital cardiovascular abnormalities, to families and society, unfortunately, enormous and profound burden. According to modern medical research found that can cause abnormal fetal heart development has the following seven risk factors:

First, there is family history of congenital heart disease. At the same time, brothers and sisters suffering from congenital heart disease, parents and children suffering from congenital heart disease at the same time the situation is quite rare, and very similar to the nature of their disease. If the mothers of the first child born with congenital heart disease, the possibility of a second child ill for about 2%; if two children are congenital heart disease, the regeneration of infants with congenital heart disease may be increased to 10%. If the mothers suffering from congenital heart disease, the second generation suffering from the risk of disease first was 10%.

Second, pregnant women with diabetes without treatment and control of disease, will be caused by fetal congenital heart disease risk of 2%, if the disease control and stability during early pregnancy, then the danger of decline.

Third, pregnant women in early pregnancy exposure to teratogenic drugs such as lithium, phenytoin, or steroids, can lead to fetal congenital heart disease prevalence rate of 2 percent.

Fourth, during early pregnancy were exposed to radioactive substances such as X-rays, isotopes, such as excessive exposure.

V. virus. Women in the first three months of pregnancy, especially in three weeks -8 weeks of pregnancy, such as by viral infection, fetal heart-prone vascular malformation. Rubella virus which is caused by fetal congenital heart disease the major culprit. In addition, influenza, mumps, coxsackie virus, herpes viruses tend to be congenital heart disease in children of the "perpetrators."

VI mating close relatives. Marriage is the next of kin in case of fetal teratogenic risk factor for CHD.

Seven or bad habits. Pregnant women hobby "desperate for a smoke," or smoking husband, the wife "passive smoking" will enable the fetal malformation or congenital heart disease occurred in children. The incidence of infant congenital heart disease, smoking mothers of babies born to smoking mothers is not twice. Husband and wife "drink the same room to conceive," will occur fetal chromosomal abnormalities, gave birth to babies suffering from disease of alcoholism, most associated with cardiovascular abnormalities.

Early detection of congenital heart disease in children is crucial to the birth. In the 20 weeks -28 weeks of pregnancy, the use of cross-section of cardiac ultrasound scanners, can be found in fetal cardiac clear whether there is any "defect." In addition, also found that the availability of fetal ascites or edema, etc., so that the fetus is suffering from heart deformities.
