A few key factors that seem to be similar all across the world may help you prevent having a stroke. “Ten risk factors that can be modified are responsible for nine of 10 strokes worldwide, but the ranking of those factors vary regionally, says a study led by researchers of the Population Health Research Institute (PHRI) of McMaster University. Prevention of stroke is a major public health priority, but the variation by region should influence the development of strategies for reducing stroke risk, say the authors of the study published in The Lancet. Stroke is a leading cause of death and disability, particularly in low-income and middle-income countries. The two major types of stroke include ischaemic stroke caused by blood clots, which accounts for 85% of strokes, and haemorrhagic stroke or bleeding into the brain, which accounts for 15% of strokes. The study led by Dr. Martin O’Donnell and Dr. Salim Yusuf of the Population Health Research Institute at McMaster and collaborators from 32 countries, builds on findings from the first phase of the INTERSTROKE study which identified ten modifiable risk factors for stroke in 6,000 participants from 22 countries. This full-scale INTERSTROKE study added 20,000 individuals from 32 countries in Europe, Asia, America, Africa and Australia, and sought to identify the main causes of stroke in diverse populations, young and old, men and women and within subtypes of stroke. This study has the size and scope to explore stroke risk factors in all major regions of the world and within key populations,” said O’Donnell, a principal investigator for the PHRI and professor of translational medicine at HRB-Clinical Research Facility, NUI Galway.”
