Background Pulmonary arterial hypertension (PAH) is a chronic disease of the pulmonary vasculature that can lead to heart failure and premature death. Assessment patients with PAH includes performing 6-minute walk test (6MWT) in clinics. We developed smartphone app compute walked distance (6MWD) indoors, by counting U-turns, outdoors, using satellite positioning. Objective The goal research was...

Abstract Heart failure (HF) is a chronic disease with high hospitalizations rates and increased mortality. The six-minute walk test (6MWT) standardized method to assess the functional health of HF patients by measuring distance walked in six minutes [1]. improved 6MWT new filter algorithms, based on development smartphone application [9], can be used everywhere good global navigation satellite ...
