How Many Measurements Are Needed to Estimate Blood Pressure Variability Without Loss of Prognostic Information?

Popis výsledku v původním jazyce

BACKGROUND Average real variability (ARV) is a recently proposed index for short-term blood pressure (BP) variability. We aimed to determine the minimum number of BP readings required to compute ARV without loss of prognostic information. METHODS ARV wascalculated from a discovery dataset that included 24-hour ambulatory BP measurements for 1,254 residents (mean age 56.6 years; 43.5% women) of Copenhagen, Denmark. Concordance between ARV from full (80 BP readings) and randomly reduced 24-hour BP recordings was examined, as was prognostic accuracy. A test dataset that included 5,353 subjects (mean age 54.0 years; 45.6% women) with at least 48 BP measurements from 11 randomly recruited population cohorts was used to validate the results. RESULTS In thediscovery dataset, a minimum of 48 BP readings allowed an accurate assessment of the association between cardiovascular risk and ARV. In the test dataset, over 10.2 years (median), 806 participants died (335 cardiovascular deaths, 206 car
