It is well established that there are significant prognostic implications resulting from the abnormal behavior of some 24-hour blood pressure (BP) parameters obtained through Ambulatory Blood Pressure Monitoring (ABPM). Among them, the abnormal behavior of the mean systolic blood pressure (SBP) and diastolic (DBP) in 24 hours, wakefulness and sleep, stand out. Specifically regarding the behavior of BP during sleep, it is already well established that the absence of nocturnal dipping has, independently, a significant impact on the increased cardiovascular risk.^, Other parameters that may have prognostic implications are early morning BP elevation and greater 24-hour BP variability.^,

Some recommendations are essential for the success of the ABPM exam, among them, the orientation for the patient to maintain their usual activities during the monitoring day. In this sense, assessing the circadian pattern of BP in hospitalized patients is not one of the indications of the method, even intending to study specific outcomes.
