Nocturnal Home Blood Pressure Monitoring
Novel devices for self-home blood pressure monitoring allow the evaluation of blood pressure during nighttime sleep. Accumulating evidence suggests that nocturnal home blood pressure monitoring provides similar values as nighttime ambulatory monitoring and with good agreement between the two methods in detecting non-dippers. More importantly, there is evidence that nocturnal home blood pressure is closely associated with indices of preclinical target organ damage, with similar correlations as with nocturnal ambulatory blood pressure, and predicts the treatment-induced regression in left ventricular hypertrophy as efficiently as ambulatory blood pressure. Some studies have shown that nocturnal home blood pressure monitoring is a useful alternative to ambulatory monitoring in the investigation of patients with sleep apnea. There is evidence that at least six readings obtained in two nights are required for a reliable assessment of nighttime home blood pressure, which provide reasonable agreement with nocturnal ambulatory blood pressure and association with indices of preclinical organ damage. These preliminary data suggest that the evaluation of blood pressure during nighttime sleep using modern low-cost automated home monitors is feasible and provides information which is clinically relevant and similar to that provided by nighttime ambulatory monitoring.
