Accurate measurement and classification of blood pressure (BP) are essential in managing hypertensive patients with chronic kidney disease (CKD). Guidelines and scientific statements recommend ambulatory BP monitoring (ABPM) or, when not available, home BP measurements (HBPM) to confirm the presence of hypertension and identify patients with white-coat or masked hypertension.1,2 Because BP follows a circadian pattern, ABPM can also be used to assess diurnal BP profile, with key parameters being nighttime (sleep) BP and nocturnal BP dipping pattern (sleep-awake BP cycle).
