·clinical-trialsA completed Stanford University trial has evaluated whether the Apple Watch paired with the Walk.Talk.Track. app can accurately replicate clinic-based six-minute walk testing in pulmonary arterial hypertension. The study also explored whether wearable-derived metrics — including heart rate variability and heart rate recovery — can detect therapeutic response earlier than the standard 12-week clinical review, with significant implications for remote patient monitoring in this high-mortality condition.
