Hypertension in pregnancy and stroke after 40 are linked
As established by a study by Norwegian authors, increased blood pressure during pregnancy increases the risk of heart attacks in adulthood and old age. These women had 57% more heart attacks or strokes than those who did not suffer from high blood pressure during pregnancy.

High blood pressure in women during pregnancy increases the likelihood of heart attacks and strokes decades after having a baby, according to a new Norwegian study. Compared to women who had normal blood pressure while waiting for the baby, women who experienced hypertensive disorders or high blood pressure during pregnancy between the ages of 40 and 70 were 57% more likely to have a heart attack or stroke.
“We already knew that women with hypertensive disorders during pregnancy were twice as likely to have cardiovascular disease when compared to women who did not have such complications. From our current research, we have determined that the excess risk of cardiovascular disease (CVD) in women with hypertensive disorders during pregnancy may be due to an increased level of traditional CVD risk factors, especially blood pressure and BMI,”says study lead author Eirin Beat Haug. Eirin Beate Haug from the Norwegian University of Science and Technology in Trondheim.
High blood pressure and high BMI (body mass index) explain 77% of the excess risk of heart attacks and strokes in women who have experienced hypertension during pregnancy, researchers report in the journal JAMA Cardiology.
The study involved 23,885 women who had one or more pregnancies under the age of 40. Of these, 2,199 women had hypertensive disorders during pregnancy. A total of 728 women had gestational hypertension only, in which high blood pressure develops during pregnancy and usually does not. But in 1,391 women, gestational hypertension progressed to more serious and potentially life-threatening high blood pressure, known as preeclampsia.
Overall, 1,155 women who never had hypertension during pregnancy still experienced heart attacks or strokes during the study period. Compared to women who did not have high blood pressure during pregnancy, women who were diagnosed with any type of gestational hypertensive disorder had a 64% higher risk of heart attack between the ages of 40 and 70. Women with hypertensive disorders during pregnancy also had a 47% higher risk of heart failure and a 40% higher risk of stroke.
The risk was even higher in women with preeclampsia. The likelihood of a heart attack in them at the age of 40 to 70 was 78% higher, heart failure - by 83%, stroke - by 46% compared with women who did not have high blood pressure during pregnancy. However, hypertension during pregnancy does not appear to affect the risk of heart problems after age 70.
One of the shortcomings of the study is the lack of data on whether women had any risk factors for cardiovascular disease before conceiving a child. However, the findings suggest that women with hypertensive disorders during pregnancy can minimize the risk of developing CVD in the future by maintaining their weight and blood pressure in the normal range.
