High blood pressure during pregnancy could elevate the risk of a future stroke

18.10.2013
Women with this pregnancy complication may benefit from blood pressure monitoring to avoid longer-term risks, researchers say

High blood pressure during pregnancy could dramatically raise a woman's lifetime risk of stroke, according to a study presented today at the Canadian Stroke Congress.

"We've found that women who had high blood pressure during pregnancy could be at higher risk of stroke, particularly if they had pre-eclampsia, which is a more severe form of high blood pressure," says Dr. Aravind Ganesh, a neurology resident at the University of Calgary. "The elevated risk of stroke could be as high as 40 per cent."

Dr. Ganesh, along with Neha Sarna (medical student), Dr. Rahul Mehta (internal medicine resident) and senior author Dr. Eric Smith (stroke neurologist), conducted a systematic review – basically, a study of studies.

Nine studies specifically looked at hypertension (high blood pressure) during pregnancy and its relationship to future risk of stroke.

The studies followed women for anywhere from one to 32 years after a pregnancy, and found consistent evidence that those with a history of hypertension in pregnancy are more likely to experience stroke in later life.

Hypertension is the most common medical problem encountered during pregnancy, complicating two to three per cent of all pregnancies. It can pose many risks, such as a decrease in blood flow to the placenta or early delivery.

Women are closely monitored throughout pregnancy for changes in blood pressure, but there are currently no specific recommendations regarding stroke-related screening or preventive measures post-partum.

"These women should be more closely followed for a re-emergence of hypertension, as well as for cholesterol, diabetes or other markers of increased risk of stroke," says Dr. Ganesh.

The exact cause of hypertension during pregnancy is undetermined, but one theory is that some women are genetically predisposed to high blood pressure and the pregnancy brings it on. Even though it might return to normal post-partum, these women need to monitor their blood pressure and to reduce their risk of having a stroke later on.

"Hypertension is the most important risk factor for stroke," says Dr. Michael Hill, co-chair of the Canadian Stroke Congress. "Knowing your blood pressure may be one of the most important steps you can take to reducing stroke risk, something that is particularly true among women with a history of pregnancy-associated hypertension."

"It's important for women to be aware of their blood pressure, and potential changes to it, during pregnancy," says Ian Joiner, director of stroke at the Heart and Stroke Foundation. "An increase is an indication that they should to talk to their doctor about their risk factors and overall vascular health. The bottom line is that it's important that women with pregnancy-related hypertension routinely monitor their blood pressure throughout their lives."

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
