Stroke: what are the chances of survival?

Ischemic stroke: two decades of evaluated data

Almost half of the stroke patients in Germany in the past 20 years have died within five years of the incident. About one in five patients has also had another stroke. This is the result of a current assessment of the Stroke Registry in Erlangen.

Researchers from the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the University of Würzburg analyzed long-term data from more than 3,000 stroke victims that have been observed via the Erlangen Stroke Register (ESPro) since 1996. Participants’ medical histories were documented for up to 20 years. The working group recently published the results of the analysis in the trade journal “Stroke”.

Extensive stroke data

So far, there has been a lack of long-term data on the likelihood of five-year survival after stroke. By evaluating the registry, the research team was able to fill this knowledge gap. Between 1996 and 2015, 3346 patients with a first ischemic stroke were included in the registry. Using the data collected, the researchers were able to track the entire supply chain, from acute treatment to rehabilitation and long-term care.

The risk of death in women is higher

Analysis shows that 41.8% of affected men died within five years of the incident. For women, this proportion was 49.6 percent higher than for men. For example, women seem to die a little more often from stroke than men.

Women suffer less from stroke

Although women have a higher risk of dying after a stroke, they suffer much less than men. According to the data, per 100,000 people, 75.8 women and 131.6 men have a stroke. Men seem to have a stroke almost twice as often as women.

Type of stroke was critical to survival

The likelihood of survival also depended on the type of stroke. Patients with arterial occlusion had the highest probability of survival (women 71.8%; men 75.9%) and those with cardioembolic stroke, which can be primarily caused by atrial fibrillation, had the highest probability of survival. lowest probability (females 35.7%; males 47.8%). The odds of having another stroke within five years of the first stroke were equal for men and women and was 20.1 percent.

Improved chances of survival

Overall, the data also shows a positive trend. The likelihood of survival for stroke victims has improved over the past two decades. This is most likely related to improved treatment options, such as the increased introduction of so-called stroke units, i.e. a service within a hospital specializing in stroke. . (v)
