Compared to women with unique pregnancy, women with twins are about twice as much risk of being hospitalized for cardiovascular disease.
- Mothers of twins have more risk of cardiovascular disease in the year following their delivery.
- The risk is particularly high in case of hypertensive pregnancy disease such as gestational hypertension or preeclampsia.
- This could be linked to the additional heart effort carried out by pregnant women of twins.
More and more twins are born in the world. According to an article published in Human Reproduction In 2021, around 1.6 million births were twin each year. Their number increased by a third compared to the 1980s, especially because of late pregnancies and medical aid for procreation. But these pregnancies are more at risk for children and the mother. In a new study, published in European Heart Journalscientists show that twin mothers have twice as much risk of being hospitalized because of a heart disease in the year following childbirth, compared to women who have a unique pregnancy.
A vast study on cardiovascular risks in the event of a twin pregnancy
This team led by Professor Cande Annanth of the Department of Obstetrics, Gynecology and Reproduction Sciences of the Faculty of Medicine Robert Wood Johnson in Rutgers, in the United States, found a high rate of maternal mortality during the First year after birth due to cardiovascular disease among women who have had a twin pregnancy. To better understand this risk, the researchers studied the data linked to 36 million hospital deliveries harvested between 2010 and 2020. They divided pregnant patients into four groups: those who had twins but normal blood pressure During pregnancy, those who have had twins and a hypertensive pregnancy disease (gestational hypertension, preeclampsia, lightning and sura eclampsia), those which had a unique pregnancy with normal blood pressure and those which have had a unique pregnancy with Hypertensive pregnancy disease.
In the year after birth, twins mothers have more cardiovascular risk
The research team found that the proportion of readmissions for cardiovascular disease in the year following childbirth was generally higher in women with twins (1.105.4 per 100,000 deliveries) than in women with a single pregnancy ( 734.1 per 100,000 deliveries). This represents a risk almost twice as high. “”For women with twins with high blood pressure during pregnancy, the risk is more than eight times higher “they note. One year after birth, the deaths of all causes, including heart disease, were higher in patients who had a single pregnancy and suffering from high blood pressure than in patients with twins with high blood pressure. “”This suggests that the risk for mothers of twins decreases in the long term “suppose these authors.
Cardiovascular disease: Why are twin mothers more at risk?
“”The maternal heart works harder for twin pregnancies than for simple pregnancies, and it takes weeks for the maternal heart to regain its state before pregnancysays Dr. Ruby Lin, specialist in fetal-maternal medicine at the Faculty of Medicine Robert Wood Johnson from Rutgers University and the main study of the study. People who have a twin pregnancy must be aware of the short -term increase in cardiovascular complications in the first year after birth, even if their pregnancy was not complicated by high blood pressure problems, such as the pre-eclampsia. “It also believes that it is necessary that health professionals take into account this risk in monitoring patients in the year following childbirth, but also when informing people followed for fertility treatment.
