Abstract

We have hypothesized that non-dipper status and left ventricular hypertrophy (LVH) are associated with the development of chronic kidney disease (CKD) in non-diabetic hypertensive patients. This study included 102 patients with an estimated glomerular filtration rate (eGFR) ≥ 60 mL/min/1.73 m2. Ambulatory blood pressure monitoring and echocardiography were performed at the beginning of the study, and the serum creatinine levels were followed. During the average follow-up period of 51 months, CKD developed in 11 patients. There was a significant difference in the incidence of CKD between dippers and non-dippers (5.0% vs 19.0%, P < 0.05). Compared to patients without CKD, patients with incident CKD had a higher urine albumin/creatinine ratio (52.3 ± 58.6 mg/g vs 17.8 ± 29.3 mg/g, P < 0.01), non-dipper status (72.7% vs 37.4%, P < 0.05), the presence of LVH (27.3% vs 5.5%, P < 0.05), and a lower serum HDL-cholesterol level (41.7 ± 8.3 mg/dL vs 50.4 ± 12.4 mg/dL, P < 0.05). Based on multivariate Cox regression analysis, non-dipper status and the presence of LVH were independent predictors of incident CKD. These findings suggest that non-dipper status and LVH may be the therapeutic targets for preventing the development of CKD in non-diabetic hypertensive patients.
