Researchers from McMaster University, Canada have found that 10 potentially modifiable risk factors are collectively associated with about 90% of strokes worldwide.
These factors are responsible for 91•5% for ischemic stroke, 87•1% for intracerebral hemorrhage. Prevention of stroke is a major public health priority says the authors of the study but the prevention strategies to reduce the stroke risk changes, region to region.
The 10 major reasons which increases the risk factor in each major region of the world, among ethnic groups, in men and women, and in all ages are high blood pressure, smoking, abdominal obesity, diet, less physical activity, lipids, diabetes mellitus, alcohol intake, stress and depression and the heart disorders.
These factors were found to be significantly associated with 90% of the risk of stroke and are the leading cause of death and disability. The two major types of stroke include ischaemic stroke caused by blood clots and haemorrhagic stroke or bleeding into the brain.
Hypertension was more associated with intracerebral hemorrhage than with ischemic stroke. Whereas smoking, diabetes, apolipoproteins, and cardiac causes were more associated with ischemic stroke.
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 10 modifiable risk factors for stroke in 6,000 participants.
