Japanese researchers said Tuesday they have developed a point-based system that can predict stroke risk over a 10-year period.
Blood pressure levels, smoking and other risk factors are taken into account in the point-based prediction model, said the researchers including Prof. Hiroshi Yatsuya of Fujita Health University in Toyoake, Aichi Prefecture. In cooperation with the National Cancer Center, Yatsuya created the model based on the results of research conducted between 1993 and 2007 on 16,000 adults across the country.
The model gives a subject points in accordance with the risk values set for six factors--age, sex, current smoking habits, presence of diabetes, body mass index and blood pressure. The points are used to calculate the 10-year stroke risk and the age of the subject's blood vessels.
For example, a 50-year-old male smoker gets 6 points for his age, another 6 for his sex and a further 4 for his smoking habit.
If his body mass index is 26, slightly over the standard, he gets an additional 2 points. He gets zero if he does not have diabetes, but gets 6 if his blood pressure without antihypertension medication is over 135/85.
With a total of 24 points, the model indicates the age of his blood vessels is 64 years old, 14 years older than his actual age. His 10-year stroke risk is calculated at between 3 percent and 4 percent.
High blood pressure is seen as the biggest risk factor, apart from age. Next is diabetes in men, followed by smoking and obesity. For women, smoking is followed by diabetes and obesity.
