Key result
Accelerometry was used to track clinical trajectories and compare motion data between 53 patients undergoing open heart or transcatheter aortic valve replacement.
Why the study?
Can accelerometry be used to track clinical trajectories and detect differences in physical activity pre- and post-intervention in patients undergoing aortic valve replacement?
Observational (n=53)
Can accelerometry be used to track clinical trajectories and detect differences in physical activity pre- and post-intervention in patients undergoing aortic valve replacement?
Accelerometry may serve as a useful tool to track clinical trajectories and physical activity changes in patients undergoing different types of aortic valve replacement.
Accelerometry technology has been used to capture motion in studies of physical activity, where these instruments have been used to assess the total amount of activity and its intensity. Clinicians have begun to realize that these characteristics could provide information about underlying health status and the use of monitors to predict clinical outcomes has increased. This presentation will review current applications of accelerometers in clinical practice. Using data from a pilot study of 53 patients undergoing aortic valve replacement either through open heart surgery or through transcatheter valve replacement, we will show the pre-intervention accelerometry data. We will then compare post-intervention accelerometry data over time, illustrating where there are significant differences between the types of valve replacement and between the pre- and the post-intervention accelerometry data. Accelerometry technology has been used to capture motion in studies of physical activity, where these instruments have been used to assess the total amount of activity and its intensity. Among other characteristics analyzed from the raw accelerometry signal include time spent sedentary, time in sleep, duration of bouts of motion, and time walking.

Harris et al. (2017) conducted an observational in Aortic valve replacement (n=53). Transcatheter valve replacement vs. Open heart surgery was evaluated on Accelerometry data over time (time spent sedentary, time in sleep, duration of bouts of motion, and time walking). Accelerometry was used to track clinical trajectories and compare motion data between 53 patients undergoing open heart or transcatheter aortic valve replacement.
