Hip Replacement Increases Stroke Risk Fourfold
Individuals who underwent a total hip replacement had at least four times the risk of suffering a stroke in the weeks immediately following, a Dutch study reported.
Researchers say more cautious monitoring after such a procedure is warranted.
Hip replacement patients showed nearly five times the rate of ischemic stroke than a control group. The rate of hemorrhagic stroke was a little more than four times as much.
The rates were highest in the two weeks following surgery but declined quickly thereafter, evening out after six to 12 weeks, said Frank de Vries, PharmD, PhD, of the Utrecht Institute of Pharmaceutical Sciences in the Holland, one of the researchers. His team's work is detailed online in Stroke: Journal of the American Heart Association.
“Risk assessment of stroke in individual patients undergoing total hip replacement (i.e. evaluate other risk factors for stroke) should be considered during the first 6 to 12 weeks,” the researchers wrote.
They examined records of 200,000 individuals, including more than 66,000 who had total hip replacement from 1998 to 2007, to reach their findings.
