Occasional high BP warning sign for stroke

12th March 2010

Researchers have said that if a person's blood pressure is occasionally high they are more in danger of having a stroke than people with constantly high readings


The study by UK and Swedish researchers was published in The Lancet.  Their findings go against current medical recommendations, which focus on measuring average blood pressure to detect and avert the risk of a stroke.

However, the new research shows that doctors should prescribe medication to regulate blood pressure.

The scientists examined how blood pressure readings changed in doctors' tests. They discovered that the patients with the highest danger of stroke were the ones with varying levels in their blood pressure readings.

The team also reviewed previous studies and found the variations in how well some blood pressure medication worked could be due to how effectively they regulated blood pressure.

Professor Peter Rothwell of the Department of Clinical Neurology at the University of Oxford, who headed the study, said the research had important consequences for how doctors diagnose and treat patients in danger of having a stroke.

"At the moment, the guidelines for GPs say not to believe a one-off unusual reading, to bring the patient back and measure again, and as long as it's not consistently high, there is no need to treat. What we're saying is don't discount that one-off high blood pressure reading," he added.
