AB  - This observational study used repeated measures over 24 hr to investigate 
      ambulatory blood pressure (BP) and physical activity (PA) profiles in 
      community-based individuals with heart failure (HF). The aims were to (a) compare 
      BP dipping and PA between two groups of HF patients with different functional 
      statuses, and (b) determine whether the strength of the association between 
      ambulatory BP and PA varies by functional status in HF. Ambulatory BP was 
      measured every 30 min with a SpaceLabs 90207; a Basic Motionlogger actigraph was 
      used to measure PA minute-by-minute. Fifty-six participants (54% female, age 
      66.96 + or - 12.35 years) completed data collection. Functional status was based 
      on New York Heart Association (NYHA) ratings. Twenty-seven patients had no 
      limitation of PA (NYHA Class I HF), whereas 29 had some limitation of PA but no 
      discomfort at rest (NYHA Class II or III HF). Patients with Class I HF had a 
      significantly greater degree of BP dipping than those with Class II/III HF after 
      controlling for left ventricular ejection fraction. In a mixed-model analysis, PA 
      was significantly related to ambulatory systolic and diastolic BP and mean 
      arterial pressure. The strength of the association between PA and BP was not 
      significantly different for the two groups of patients. These findings 
      demonstrate differences between Class I and Class II/II HF in BP dipping status 
      and ambulatory BP but not PA. Longitudinal research is recommended to improve 
      understanding of the influence of disease progression on changes in 24-hr PA and 
      BP profiles of patients with HF.
