Number of strokes (CVA) linked to aneurysms on the rise, according to a study – 11/27/2022

Records of a type of stroke (Paralysis), subarachnoid hemorrhage has increased, mainly in black men over age 65, according to a study just published in “Neurology“. evaluated data on nearly 40,000 US patients hospitalized in Florida and New York between 2007 and 2017, comparing cases between men and women by age and race.

This type of stroke is mainly caused by the rupture of an aneurysm – when a vessel expands, creating a kind of blood sac – located between the brain and the membrane that covers it. high blood pressure And Smoking This is one of the major risk factors for fracture.

During a ten-year follow-up study, the median incidence was 11 cases per 100,000 people. Over the age of 65, this number doubles. And, among blacks, it rises to 15. According to the authors, they are more likely to develop high blood pressure, and at a younger age.

“Black people are known to have genetic and socioeconomic factors that make them more vulnerable,” says neuroscientist Pauliana Biza of Israel’s Albert Einstein Hospital. The article suggests difficulties in accessing treatment and treatment may increase the risk of stroke.

“This is an integrated, retrospective, well-designed study that proposes to monitor a certain population for a certain period of time, and through that observation, to analyze possible correlations. Although it shows the reality of two American states, it is possible. To extrapolate the data to our reality”, the expert evaluates.

“Prevention, detection, treatment and may be a reflection of the individual’s lack of exposure to risk factors. We need to discuss the difficulty of monitoring and controlling these factors”, he reflects.

Less risk of breakage

In general, unruptured aneurysms, called incidental, have a low risk of bleeding, about 1%.

In this context, they can only be accompanied by monitoring the risk factors for their deterioration and observing possible changes in their physical characteristics such as growth and disorganization of their figure.

Invasive surgery or endovascular treatment is mainly recommended for aneurysms larger than 5 to 7 millimeters. However, if they break, the possibility of death or serious consequences is very high.
