Albuminuria and Glomerular Filtration in Patients with Essential Hypertension.

Background: Essential hypertension (EH) is a widespread disease. One frequent complication of EH is Chronic Kidney Disease (CKD), whose diagnosis is delayed due to its asymptomatic course. The purpose of this study is to determine the involvement of the kidneys in patients with EH by biomarkers for kidney damage (albuminuria) and glomerular filtration rate (GFR) with creatinine and cystatin C.
