Black people who survive strokes caused by an intracranial hemorrhage (ICH) are more likely than whites to have high blood pressure a year later—increasing their risk of another stroke, according to a study in the American Heart Association journal Stroke.
The study was conducted at Georgetown University Medical Center, Washington, DC, and included 162 patients (average age 59, 77%, 53%).
ICHs account for only 10% of all strokes but have a death rate of about 40% in the first month, much higher than other types of stroke. High blood pressure is the most important modifiable risk factor associated with bleeding stroke.
However, more than half of patients in the study still had high blood pressure a year after the stroke, despite taking 1 or more antihypertensive medications. There were no significant racial differences 30 days after ICH. But a year later, 63% of blacks had hypertension, compared with 38% of whites, despite taking more blood pressure medications.
The study was too small to identify which factors may explain the racial differences. However, the authors say that factors associated with lower blood pressure at follow-up in multivariable analysis were being married and living in a facility rather than a personal residence.
