What is the association between impaired diurnal blood pressure variation and a subsequent decline in glomerular filtration rate?
Davidson et al. (2006) conducted a study which found that there is an association between impaired diurnal blood pressure variation and a subsequent decline in glomerular filtration rate. This study was published in the Arch Intern Med and involved 846 patients. The results showed that patients with impaired diurnal blood pressure variation had a significantly higher risk of a subsequent decline in glomerular filtration rate, compared to those without impaired diurnal blood pressure variation. The authors concluded that impaired diurnal blood pressure variation may be associated with a subsequent decline in glomerular filtration rate and should be monitored in order to reduce the risk of further decline.
