2017

Congenital heart disease (CHD) is the most common birth defect. It is due to dysfunction of the heart and great vessels during embryo development stage, or the channel was not closed after birth. This study focuses on investigating the influence of virus infection and medicine history during pregnancy on the incidence rate of CHD of fetus. We conducted a retrospective birth cohort study of infant born in the maternal and child health hospital of Fanyu district in Guangzhou. Five thousand three hundred eighty one cases with complete medical records, including mothers, fathers, and infants, were enrolled. The exposure history of mothers to virus and medicine from 6 months before pregnancy to prenatal examination was investigated, including mflu, mumps, measles, rubella, chickenpox, and hepatitis and antibiotics, tocolytic agent, anticonvulsants, antipyretic and analgesic, antitumor drug, folic acid supplement, and contraceptive. The relationship between virus infection and medicine history during pregnancy and CHD was analyzed. There was statistical difference between a normal group and a defected group in influenza infection and tocolytic agent and contraceptive pill. The exposure history to influenza and medicines, such as tocolytic agent and contraceptive pill, during pregnancy influenced the incidence rate of CHD of fetus.
