Abstract

Objectives: High 24-h ambulatory blood pressure (ABP) variability is associated with poor cardiovascular outcomes. We analysed a large ABP monitoring database containing data from hypertensive patients treated with telmisartan/amlodipine combination or various monotherapies with the aim of quantifying the 24-h distribution of blood pressure (BP) reduction by treatment through the smoothness index and of developing and testing a new treatment-on-variability index (TOVI) to quantify the effects of treatment on both mean BP and BP variability. Methods: ABP data were pooled from 10 studies (N=4294) with a median follow-up of 60 days. Smoothness index was calculated by dividing the mean of treatment-induced hourly BP reductions by its SD. TOVI was calculated as the ratio of the mean of hourly BP reductions to weighted 24-h BP SD (weighted mean of daytime and night-time SDs) under treatment. Results: The SBP/DBP smoothness index and TOVI values of telmisartan/amlodipine combination were significantly (P
