The study consisted of 4,600 white, black and Hispanic Americans who were followed for six years. Within that time, nearly half of them experienced bleeding stroke.
The risk of bleeding stroke with untreated blood pressure was found to increase 11 times in the blacks, 9.8 times in Hispanics, and 9.4 times in the whites.
Furthermore, blood pressure was more likely to be untreated in Hispanics, then blacks, and followed by whites. Access to medical care was seen as a possible reason as to why Hispanics and blacks often have higher rates of untreated blood pressure.
Even among those with treated blood pressure, blacks were still 75 percent more likely to have bleeding stroke than whites, and Hispanics had a 50 percent higher likelihood than whites.
The findings are still at their early stage, and additional review is required.
