Hypertension research

Hypertension, or high blood pressure, affects 10-15% of pregnancies and can increase the risk of complications for mother and baby.

Chronic hypertension, or constant high blood pressure, affects around 5% of pregnancies and remains one of the main causes of maternal death in the UK. Mothers are at risk of stroke and damage to their kidneys, while their babies may be born early or underweight. What’s more, it is one of the most common chronic problems in women around the age they have children.

In 2015 Tommy’s opened the Hypertension in Pregnancy Clinic at St. Thomas’ Hospital in London. Here, we research new ways to help women with chronic hypertension and provide specialist care to women suffering from high blood pressure.

Research highlights

  • The PEACHES trial is researching how we can tell early on if women with high blood pressure are likely to experience complications
  • The CRADLE project is developing an easy, cheap way of measuring blood pressure anywhere in the world
  • The PANDA study is looking at the difference between two drugs, NifeDipine and Labetalol, for treating chronic hypertension during pregnancy
