Web11 de abr. de 2024 · Entropy features were calculated from the longitudinal wearable sensor data, such as heart rate and mobility-related measurements, in order to characterize time series variability and complexity. Our best performing model achieved an AUC of 83%, and at 80% sensitivity achieved 75% specificity and 57% positive predictive value. WebA longitudinal study (or longitudinal survey, or panel study) is a research design that involves repeated observations of the same variables (e.g., people) over short or long periods of time (i.e., uses longitudinal data ). It is often a type of observational study, although it can also be structured as longitudinal randomized experiment.

There are different ways to measure the regional function of the wall. It has been proposed to measure the speed of the LV wall motion, the thickening of the wall, or other changes in the shape of small regions of the wall as it contracts and relaxes. The latter is best measured using the mechanical quantity called “strain." Strain can be described as the percentile change in spacing between two points on a deforming object. Here are some important points about strain:
