Abstract

Accurate measurement of cardiopulmonary hemodynamics and exercise capacity is vital for PAH diagnosis and management. Terminal digit bias in clinical measures introduces non-differential error. Remote monitoring using implanted devices eliminated this bias, demonstrating its potential to enhance accuracy in both clinical practice and research by reducing variability in observer-reported data.
