Diabetes and Hypertension Add Up to Stroke
The combination of type 2 diabetes and hypertension can dramatically
increase the risk of stroke, according to a group of researchers in Finland
who reported a study in the December 2005 issue of Stroke.
Investigators studied 49,582 people, 2574 years old, none of whom
had a history of stroke or coronary heart disease.
Researchers conducted a series of detailed surveys over a period of several
years. At the beginning of the study, participants completed a questionnaire
that asked in-depth information about health. High blood pressure and diabetes
status were determined by asking about medical care and prescribed
medications. Participants were followed for an average of 19 years.
Information about stroke and stroke-related deaths was derived from national
sources and computerized databases.
Analysis of data revealed that both high blood pressure and diabetes raise
the chance of stroke, but the effect of the two in combination is dramatic.
People with both high blood pressure and diabetes are 4.5 times more likely to
have a stroke, and if they do have a stroke are more than 9 times more likely
to die from it than somebody without either
disease.
