Resistant hypertension (RH) is a common problem in patients with chronic kidney disease (CKD). A decline in the glomerular filtration rate (GFR) and increased albuminuria are associated with RH; however, there are few published studies about the prevalence of this entity in patients with CKD. Objective: To estimate the prevalence of RH in patients with different degrees of kidney disease and analyse the characteristics of this group of patients. Methods: A total of 618 patients with hypertension and CKD stages I–IV were enrolled, of which 82 (13.3%) met the criteria for RH. Results: RH prevalence increased significantly with age, the degree of CKD and albuminuria. The prevalence of RH was 3.2% in patients under 50 years, 13.8% between 50 and 79 years and peaked at 17.8% in patients older than 80 years. Renal function prevalence was 4%, 15.8% and 18.1% in patients with an estimated glomerular filtration rate (GFR) of >60, 30–59 and 300 mg/g respectively. In a logistic regression model, the characteristics associated with resistant hypertension were age, history of cardiovascular disease, GFR, albuminuria and diabetes mellitus. A total of 47.5% of patients with resistant hypertension had controlled BP (
