Whether target organ damage is associated with blood pressure (BP) variability independent of level remains debated. We assessed these associations from 10-minute beat-to-beat, 24-hour ambulatory, and 7-day home BP recordings in 256 untreated subjects referred to a hypertension clinic. BP variability indices were variability independent of the mean, maximum-minimum difference, and average real variability. Effect sizes (standardized ) were computed using multivariable regression models. In beat-to-beat recordings, left ventricular mass index (n=128) was not (P0.18) associated with systolic BP but increased with all 3 systolic variability indices (+2.97-3.53 g/m(2); P
