They are also more likely to die from a stroke within 30 days, have a stroke at a younger age or have a hemorrhagic stroke – a more severe type caused by a burst blood vessel bleeding in or near the brain.
"The results show there is a high association between the wealth of a country, the portion of their GDP put into health-care and outcomes for stroke patients," said Dr. Gustavo Saposnik, senior author of the study and director of the Stroke Outcomes Research Unit at St. Michael's Hospital.
The correlation likely exists because these countries often don't invest enough in resources for the prevention and management of stroke risk factors, such as smoking, high blood pressure and diabetes, he said.
"If you can reduce the risk factors, you reduce the risk of stroke."
Instead of looking at data from individuals or families, Dr. Saposnik and colleagues took a unique approach from previous research and analyzed the data from regions and countries.
They linked stroke risk, 30-day death rate, hemorrhagic stroke incidence and age at disease onset to three economic indicators: GDP, money spent on health per capita and unemployment rate.
Unlike the other two indicators, unemployment rate did not affect any of the other stroke outcomes.
The results were published today in Stroke: Journal of the American Heart Association.
The authors said the findings expose the potential consequences of low investment on health. "Hopefully this research will provide the necessary background to help countries make the changes in how different resources and money are allocated," Dr. Saposnik said.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
