Key result
HRV serves as a potential frailty biomarker in older adults by reflecting cardiac autonomic modulation.
Why the study?
Frailty involves loss of physiological complexity and vulnerability in older adults, requiring investigation into monitoring methods like heart rate variability to assess its relationship with frailty.
Does heart rate variability monitoring serve as a biomarker for frailty in older adults?
Does heart rate variability monitoring serve as a biomarker for frailty in older adults?
Heart rate variability monitoring, including through wearable devices, may serve as a useful non-invasive biomarker for detecting and monitoring frailty in older adults.
May support non-invasive HRV frailty monitoring in older adults; leaves open prospective validation before clinical adoption.
Frailty is a state of critical loss of physiological complexity resulting in greater vulnerability to stressors and has been characterized as a debility syndrome in the older adult. Changes in functional capacity and the cardiovascular system during aging are the most significant and relevant for this population, including the clinically healthy. In this sense, this review aims to investigate methods to monitor the performance of older adults, such as heart rate variability and verify how it can be related to frailty. It contributes to understanding that the changes in heart variability can be a marker for frailty in older adults.
