Nicotine and congenital heart disease
Abstracts
Initial Award Abstract |
|
Smoking during pregnancy is associated with congenital heart defects. In the US, about 1 in 8 women smokes during pregnancy. The situation is even more serious in California, where about 1 in 4 women smokes during pregnancy. Although smoking harms both pregnant women and the fetus, only about 20 percent of women who smoke quit during pregnancy. This is a major health problem for both women and children. It is therefore important to understand how smoking during pregnancy causes congenital heart disease.
Heart malformations associated with maternal smoking most commonly involves particular regions of the heart - the outflow tract of the heart and heart valves. Abnormal outflow tract formation may result in mixing of blood and poor oxygenation. Or, it may cause significant shunting of the blood and overloading of the heart. Similarly, heart valve malformations may cause blockage or leakage of the blood flow. Children with these congenital heart diseases often have poor circulation, congestion in the lungs and heart failure. Some infants are more susceptible to maternal smoking during pregnancy. Infants with Down syndrome (due to an extra copy of chromosome 21) have 5 times higher risk of having defects in the outflow region of the heart if their mother smoked during pregnancy. This suggests that underlying genetic factors can predispose the fetus to smoking-related heart defects.
Despite the medical importance of fetal congenital heart defects related to maternal smoking, there are surprisingly few studies of how nicotine may affect fetal heart development. We have generated several mouse models that have heart defects, very similar to those associated with maternal smoking. We plan to use these animal models to study how nicotine causes abnormal heart formation, and how nicotine interacts with genetic factors in congenital heart disease. Detailed understanding of the underlying mechanisms will enhance our awareness of this smoking-related disease and pave the way for better prevention and treatment. |
