renal complications and stroke than white patients with high blood pressure," Touyz said. "If we can understand better what are the mechanisms that are responsible for the differences in hypertension rates and why the complications are more severe, it will allow us to better treat patients who are black."
In addition, certain high blood pressure treatments don't work as well in blacks. Classes of drugs that inhibit the renin-angiotensin system, which can raise blood pressure when overactive, tend to be more effective in whites, Touyz said.
The data used in the study did not include information about what medications participants were taking or the doses.
Education and outreach programs targeting minorities, along with aggressive screening and treatment for hypertension, would help eliminate some of the disparities, the researchers said.
The American Heart Association has more on high blood pressure.
