The incidence of blood clot-related strokes fell among whites in the Greater Cincinnati/Northern Kentucky area for the first time, according to a new long-term surveillance study. However, there was no decrease in stroke rates among blacks.
“It’s encouraging that, for the first time ever in our study area, there is a drop in the most common type of stroke,” said Dawn Kleindorfer, lead author of the study. “However, it’s very disappointing that the racial disparity seems to be getting worse.”
Investigators found that the age-adjusted annual rate of ischemic stroke (those caused by a blood clot) resulting in hospitalization changed between 1999 and 2005 from:
Researchers used data from the Greater Cincinnati/Northern Kentucky Stroke Study, which gathered information on all first strokes occurring in a five-county area with 1.3 million people.
