Doctors should urgently lower and stabilise the blood pressure of stroke patients, according to Australian research that could lead to treatment changes around the world.
The greater the variation in blood pressure within the first week, the more likely the patient is to die or suffer major disability, says research leader Professor Craig Anderson of The George Institute for Global Health and the University of Sydney.
The research, published in The Lancet medical journal, suggests it is important not only to urgently reduce blood pressure in stroke patients, but also to ensure the blood pressure is sustained for several days.
"Blood pressure monitoring should be frequent throughout the patient's stay in hospital," Prof Anderson said.
He cautioned doctors against being "falsely reassured" by a few normal blood pressure readings among wide fluctuations.
Prof Anderson said the research was important because it showed the role of fluctuating blood pressure in triggering a brain haemorrhage stroke.
This meant current treatment methods should be changed.
Dr Erin Lalor, chief executive of the National Stroke Foundation, said the research could have a huge impact on the quality of life of stroke survivors.
"Stroke is a leading cause of disability in Australia and changes peoples lives suddenly and dramatically."
