Low night-time heart rate is longitudinally associated with lower augmentation index and central systolic blood pressure in hypertension

Abstract
Several studies have shown that the augmentation index (AIx) is negatively correlated with heart rate (HR). This led some authors to claim that the use of HR-lowering drugs may be detrimental in hypertension. The aim of this study was to assess the longitudinal and cross-sectional relationships of HR with AIx and central blood pressure (BP) in 346 subjects from the HARVEST (mean age 30.7 ± 8.5 years).
