Comparing effect of definition of diurnal periods by diary, fixed periods, and actigraphy on ambulatory blood pressure parameters in a Chinese population.

ABSTRACT:

Background

Reliable measurement of daytime and night-time blood pressure (BP), and degree of BP dipping during sleep during ambulatory blood pressure monitoring (ABPM) requires an accurate definition of sleep time (diurnal definition). However, superiority of any diurnal definition on ABPM remains unclear. The present study compared mean daytime and night-time SBP and DBP using different methods for diurnal definition: patient's diary, wide-defined and narrow-defined fixed periods, and actigraphy, in a Chinese population with diagnosed essential hypertension. We hypothesize that BP values from actigraphy are different from BP obtained by other methods and associated with end-organ damage (i.e. impaired renal function, proteinuria, left ventricular hypertrophy).
