Researchers find new harm that preeclampsia would bring to pregnant woman

Heart abnormalities during women's pregnancy may increase the risk of pregnancy-related high blood pressure in future pregnancy (pre-eclampsia).

According to a Feb. 22 research in the journal Hypertension, the incidence of pre-eclampsia during pregnancy is about 3% to 8%, which is a serious complication of pregnancy. The researchers said that when preeclampsia happened, neonatal often need to be quickly taken out in order not to cause harm to the mother and child.

Associate Professor Herbert Valensise from the second university school of medicine, gynecology and obstetrics of Rome said, "Women who are pregnant with preeclampsia for the first time should be informed of the potential risks and what recommendations they should comply with from the doctors. The doctors should take preeclampsia during pregnancy as risk factors for cardiovascular adverse events for pregnant women in following days. When we asked the patient about the cardiac risk factors such as outside smoking, alcohol consumption as well as family history and other lipids, blood pressure especially the occurrence of pre-eclampsia should also be asked during pregnancy."

Previous studies showed that women who had a history of pre-eclampsia in subsequent pregnancies are more prone to meet this situation again, and the risk of cardiovascular disease is greatly increased later. This new study included 75 women who show preeclampsia during first pregnancy and also included 147 healthy women pregnant for the first time. The average age of these women was 34-years-old, and all women received electrocardiogram trace test after they gave birth to children in the 12-18 month. Within 24 months, all of these women become pregnant again.

The researchers found that 29 percent of the women pregnant for the first time with pre-eclampsia suffered from the same disease in the second pregnancy. Compared with women who didn't have pre-eclampsia previously, the former type of pregnant women's form and function of ventriculus sinister changed. To be specific, there was a significant reduction in blood pump of ventriculus sinister.

The researchers pointed out that they need larger sample data to verify the findings again in the future.
