AB  - OBJECTIVE: Assessment of habitual physical activity (PA) in patients with heart 
      failure. METHODS: This study included 50 patients with heart failure (61.9 +/- 4.0 
      yr). Seven days of PA were assessed by questionnaire (AQ), pedometer, and 
      accelerometer and correlated with prognostic markers including VO(2peak), percent 
      left-ventricular ejection fraction, N-terminal pro-B-type natriuretic peptide, 
      and New York Heart Association (NYHA) functional class. RESULTS: Accelerometry 
      showed a stronger correlation with VO(2peak) and NYHA class (R = .73 and R = 
      -.68; p < .001) than AQ (R = .58 and R = -.65; p < .001) or pedometer (R = .52 
      and R = -.50; p < .001). In the multivariable regression model accelerometry was 
      the only consistent independent predictor of VO(2peak) (p = .002). Moreover, when 
      its accuracy of prediction was tested, 59% of NYHA I and 95% of NYHA III patients 
      were correctly classified into their assigned NYHA classes based on their 
      accelerometer activity. CONCLUSION: PA assessed by accelerometer is significantly 
      associated with exercise capacity in patients with heart failure and is 
      predictive of disease severity. The data suggests that PA monitoring can aid in 
      evaluating clinical status.
