Researchers discovered that 10 controllable risk factors account for 90pc of all strokes worldwide. Of these modifiable risk factors, high blood pressure (hypertension) is the most important.

"The study confirms that hypertension is the most important modifiable risk factor in all regions, and the key target in reducing the burden of stroke globally," said study co-leader Dr Martin O'Donnell of the HRB-Clinical Research Facility in Galway, Ireland.

Preventing strokes is a major public health priority and strategies for reducing people's risk should be based on key preventable causes of stroke.

The study, published in The Lancet, involved nearly 27,000 people from every continent.

"This study is of an adequate size and scope to explore stroke risk factors in all major regions of the world, within key populations and within stroke subtypes," said Dr O'Donnell.

Eliminating high blood pressure was estimated to reduce risk by nearly 48pc, the findings showed.
