Why the study?
Does physical activity assessed by accelerometer correlate with prognostic parameters in elderly patients with heart failure?
Population
50 elderly patients with heart failure, mean age 61.9 ± 4.0 years.
Design
Cross-sectional
Follow-up
7 days
Key result
Physical activity assessed by accelerometry showed a strong correlation with VO(2peak) (R = 0.73, p < 0.001) and NYHA class (R = -0.68, p < 0.001) in patients with heart failure.

Does physical activity assessed by accelerometer correlate with prognostic parameters in elderly patients with heart failure?
Effect estimate: R = .73 and R = -.68
p-value: p=< .001
Accelerometer-based physical activity monitoring strongly correlates with exercise capacity and disease severity in heart failure patients, outperforming questionnaires and pedometers.
Jehn et al. (2011) conducted an observational in heart failure (n=50). Habitual physical activity assessed by accelerometry vs. Questionnaire (AQ) and pedometer was evaluated on Correlation with VO(2peak) and NYHA class (R = .73 and R = -.68, p=< .001). Physical activity assessed by accelerometry showed a strong correlation with VO(2peak) (R = 0.73, p < 0.001) and NYHA class (R = -0.68, p < 0.001) in patients with heart failure.
