Hypertension is the single major risk factor for stroke, which is a highly preventable medical condition globally, irrespective of age and sex, reveals a study led by an Indian-origin researcher. Stroke which is caused when poor blood flow to the brain results in cell death, is the leading cause of mortality and disability, particularly in low-income and middle-income countries. The findings showed that 47.9 per cent of stokes were caused as a result of hypertension whereas physical inactivity caused 35.8 per cent. “The study confirmed that hypertension is the most important modifiable risk factor in all regions and is therefore the key target in reducing the burden of stroke globally,” said Salim Yusuf, Professor at McMaster University in Ontario, Canada.
