Pregnancy increases the risk of stroke in young women. It was the result of a study published in JAMA Neurology in October 2016. There is now more information on the link between pregnancy and STROKE, as well as on the type of STROKE.
A new study, presented at the American Stroke Association’s International Stroke Conference 2018, shows the existence of a type of STROKE, particular that affects pregnant women. It is subarachnoid hemorrhage, spontaneous hemorrhages that occur by rupture of blood vessels at the surface of the brain causing a hemorrhage between the brain and its envelopes, the meninges.
Few studies on the subject
This type of stroke is due to an abnormality in the arteries of the brain, which can lead to broken blood vessels. Little research has been conducted on the occurrence of these STROKE among young pregnant women.
The researchers, led by Kaustubh Limaye, of the university of Iowa in the United States have used a national database of the health system. Thus, they have obtained information on the case of 3978 patients who are pregnant, aged 15 to 49 years, for the period from 2002 to 2014.
The young women most affected
The proportion of women who are victims of subarachnoid hemorrhage is increased from 4% to 6% over the period. This rate was higher among young women. Among those aged 20 to 29 years, 20% have been victims of a STROKE type, subarachnoid hemorrhage, whereas among women aged 40 to 49 years of age, this rate was less than 1%. After hospitalization in the emergency room, pregnant women are, however, better than the other : 8% died, compared with 17% for women non-pregnant who have this type of STROKE.
When women are pregnant, they are more likely to develop high blood pressure or gestational diabetes, which increases traditionally the risk of STROKE. An element that has not been analyzed in this study.
