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: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
