Brief summary
Isolated nocturnal hypertension (INH) has been studied among the general population and hypertensive patients. However, little insight is available on the prognostic effect of INH in patients with chronic kidney disease (CKD). This study investigated the prognostic effect of INH in a cohort of Chinese patients with nondialysis CKD.
Detailed description
Patients with or without isolated nocturnal hypertension will be enrolled in this study, and the patients with isolated nocturnal hypertension will be randomly divided into two groups and treated with bedtime or awakening doses of potassium losartan. Any patients who had any antihypertension medication at bedtime would withdrawal the drugs for 2 weeks before ABPM. Patients with isolated nocturnal hypertension will be randomly divided into two groups and received a bedtime or awakening dose of potassium losartan.
