Higher Blood Pressure Seen in Kidney Donors
Closer surveillance of donors urged to reduce risk of ischemic heart disease and stroke
TUESDAY, Aug. 1 (HealthDay News) -- Kidney donors may experience a higher blood pressure increase in the five to 10 years following donation than would be expected with normal aging, according to a meta-analysis published in the Aug. 1 issue of the Annals of Internal Medicine.
Neil Boudville, M.D., of the University of Western Australia in Perth, and colleagues reviewed 48 studies from 28 countries that followed 5,145 donors to assess the risk for hypertension after kidney donation.
Five or more years after donation, the average blood pressure in donors was 5 mm Hg higher than in control subjects, the researchers found.
"In the general population, every 10-mm Hg increase in systolic blood pressure and 5-mm Hg increase in diastolic blood pressure is associated with a 1.5-fold increase in death from ischemic heart disease and stroke," the authors conclude. "Whether an increase in blood pressure from kidney donation is similarly prognostic requires future consideration, because closer surveillance and early intervention in otherwise healthy adults could offset any such risk."
