A cynical and mistrustful personality apparently leads to greater blood pressure fluctuations for blacks than whites, which could help explain blacks' higher heart disease rates, a Duke University researcher reported Friday at the American Psychosomatic Society meeting here.
Large variations in systolic blood pressure have been linked to the development of heart disease, says psychologist James Lane. So has a suspicious, hostile personality. Overall, blacks tend to score higher on tests for such hostility, he says.
Lane and co-author Redford Williams examined whether the most hostile — those in the upper third on the test — had more blood pressure variability than less hostile people. The team had 152 healthy whites and blacks wear blood pressure cuffs and took more than 50 measurements from them over 24 hours.
The most hostile whites had no more blood pressure variability than less hostile whites or blacks. But the most hostile blacks had about 25% more variability in their systolic blood pressure readings than the others.
"Hostility may be a more important heart disease risk factor for blacks than whites," Lane says
