HOPE OVER HEART PILL.
HEART disease sufferers could get a safer drug than standard blood thinning medication.
People with irregular heartbeats are usually given warfarin to prevent clots forming and causing strokes, but it can react with other drugs and is not ideal for frail, elderly patients.
But rivaroxaban is twice as effective at blocking fatal brain bleeds and has fewer side effects, experts from Edinburgh University and North Carolina's Duke University found.
Around 800,000 people suffer from irregular heartbeats which could make them up to six times more likely to suffer strokes, caused by a blood flow interruption to the brain.
Edinburgh University's Prof Keith Fox said: "An alternative drug for patients with irregular heartbeats is just as effective while also easier to prescribe and take."
Irregular heartbeats affect about 10% of over-65s, the New England Journal of Medicine report added.
