Does hypertension during pregnancy increase cardiovascular-related mortality risk?

This study examined the link between hypertensive disorders during pregnancy and cardiovascular disease mortality risk (death from stroke or heart disease). The authors concluded that women with a history of hypertension during pregnancy are at an increased risk of future cardiovascular mortality. 

Some women experience hypertensive disorders during pregnancy (HDP). There are different types and severities of hypertension during pregnancy. Gestational hypertension develops after 20 weeks of pregnancy. Preeclampsia or eclampsia is hypertension that occurs during pregnancy with increased protein in the urine. There is evidence to suggest that these conditions can lead to long-term cardiovascular problems such as heart disease, stroke and death. Cardiovascular disease (CVD) is a common cause of death and identifying risk factors for CVD could help in appropriate treatment selection early on.

Records were collected from 31,656 women who gave birth in the same hospital. 14% of these women had experienced HDP. Mortality rates were compared over a study period of 20 to 29 years.

The authors concluded that women who experience HDP are at a greater risk of dying from a cardiovascular-related illnesses than those who do not. 

Since the study only recorded 129 deaths in women with HDP, larger studies are needed to confirm these findings.

Consult with your physician to discuss possible screening and intervention methods for hypertensive disorders of pregnancy.
