Key Takeaways

• PAH patients exhibit low physical activity and poor sleep quality, with wearable technology offering objective insights beyond the 6MWD test.
• Positive correlations exist between deep/REM sleep and physical activity, while negative correlations are seen with sedentary behavior.
• Wearable devices can provide prognostic data and indicate therapeutic response, overcoming limitations of traditional assessments.
• Interventions targeting sleep or activity may positively influence other health behaviors, suggesting a need for further research.

For this analysis, outcomes were compared between individuals who had pulmonary arterial hypertension (PAH) and healthy controls by using Fitbit-derived data over 12 weeks and then at a 1-year follow-up.

Pulmonary arterial hypertension (PAH) is likely to lead to low levels of physical activity and poor sleep...
