Recently, in a research report published in the International Journal of the American Heart Association, scientists from Cambridge University and other institutions found that women who experienced high blood pressure during pregnancy or later in life had a higher risk of heart disease and heart failure.
In western countries, about 1% - 6% of pregnant women will be conservative effect of hypertension, when their blood pressure will tend to a normal level after delivery, this situation is called pregnancy induced hypertension, the difference with preeclampsia is that there is no trace protein in the urine of patients. Nowadays, more and more clinicians realize that women with gestational hypertension are more likely to have hypertension in later stage Can have cardiovascular disease.
However, a large number of studies on different cardiovascular diseases, such as heart disease and heart failure, tend to produce mixed results. In order to reveal the correlation, the researchers conducted a retrospective comprehensive analysis of 21 studies involving 3.6 million women, of whom 128000 women had previously suffered from pregnancy induced hypertension. This type of study is a review of all existing studies The data of the study are combined to help researchers compare and consolidate the frequently conflicting research results, so as to draw more reliable conclusions.
The researchers found that compared with women who did not have hypertension during pregnancy, pregnant women who experienced hypertension for the first time in pregnancy had an overall risk of cardiovascular disease by 45%, while the risk of coronary heart disease increased by 46%; women affected by hypertension during one or more pregnancies had an increased risk of cardiovascular disease by 81%, coronary heart disease by 83%, and heart failure by 83% 77%. When we analyzed all available studies, women with hypertension during pregnancy, even if they did not develop preeclampsia, were more likely to develop multiple types of cardiovascular disease, according to researcher Clare Oliver Williams. This study provides evidence of a link between pregnancy and the risk of subsequent cardiovascular events, after researchers found that recurrent miscarriage, preterm birth, fetal growth restriction, and preeclampsia are all directly associated with a higher risk of heart disease.
The researchers said that at present, they are not fully aware of why pregnancy induced hypertension is directly related to the occurrence of late stage heart disease. However, studies have shown that pregnancy induced hypertension can cause persistent damage to the body and then cause cardiovascular disease. Therefore, women with pregnancy induced hypertension may be susceptible to cardiovascular disease, which may be due to the huge impact of pregnancy on women's body Big demand.
Finally, the researchers said that pregnant women with high blood pressure may not be their problem, and heart disease is not an inevitable result. Women who have experienced pregnancy induced hypertension may encounter thorny problems, but how to deal with them is the most important thing. Positive small changes may help them, such as eating more fruits and vegetables, and exercising regularly Better way.
