Remote exercise assessment in pulmonary hypertension

Area of Science:

• Cardiology
• Pulmonology
• Digital Health

Background:

• Exercise assessment is crucial for prognosis in pulmonary arterial hypertension (PAH).
• Digital tools are emerging as alternatives to traditional outcome measures.
• Remote patient monitoring is increasingly important in managing chronic diseases like PAH.

Purpose of the Study:

• To review existing methods for remote exercise assessment in PAH.
• To evaluate the utility of digital alternatives to traditional exercise tests.
• To discuss the potential of digital six-minute walk tests (6MWT) in PAH management.

Main Methods:

• Review of current literature on remote exercise assessment in PAH.
• Analysis of digital structured exercise tests, focusing on the digital 6MWT.
• Evaluation of actigraphy and wearable technology for PAH monitoring.

Main Results:

• Actigraphy metrics show population-level promise but high individual variability.
• Digital 6MWT are safe, accurate, and well-accepted by PAH patients.
• Wearable integration enhances digital 6MWT and offers longitudinal endpoint potential.

Conclusions:

• Digital 6MWT and other remote measures need further validation.
• Future studies must establish their ability to reflect disease severity and sensitivity to change.
• Minimal clinically important differences are required for clinical implementation in PAH longitudinal monitoring.
