Associations between Cardiovascular Signal Entropy and Cognitive Performance over Eight Years
(2021)In this study, the relationship between non-invasively measured cardiovascular signal entropy and global cognitive performance was explored in a sample of community-dwelling older adults from The Irish Longitudinal Study ... -
Associations between neurocardiovascular signal entropy and physical frailty
(2021)In this cross-sectional study, the relationship between noninvasively measured neurocardiovascular signal entropy and physical frailty was explored in a sample of community-dwelling older adults from The Irish Longitudinal ... -
Blood Pressure Signal Entropy as a Novel Marker of Physical Frailty: Results from the FRAILMatics Clinical Cohort
(2022)In this study we investigated the association between information entropy in short length blood pressure signals and physical frailty status, in a group of patients aged 50+ recruited from the Falls and Syncope Unit at ... -
Cardiovascular signal entropy predicts all-cause mortality: evidence from The Irish Longitudinal Study on Ageing (TILDA)
(2022)In this study, the relationship between cardiovascular signal entropy and the risk of seven-year all-cause mortality was explored in a large sample of community-dwelling older adults from The Irish Longitudinal Study on ... -
Functional clustering of continuous cardiovascular and brain oxygenation signals during an active stand test in The Irish Longitudinal Study on Ageing (TILDA)
(2023)In this study, we performed K-shape functional clustering of two non-invasive continuous cardiovascular (systolic Blood Pressure: sBP) and brain oxygenation (left frontal lobe Tissue Saturation Index: TSI) times series ... -
Orthostatic hypotension and novel blood pressure associated gene variants in older adults: data from the TILDA Study
(2020)Orthostatic hypotension (OH) is associated with increased risk of trauma and cardiovascular events. Recent studies have identified new genetic variants that influence orthostatic blood pressure (BP). The aim of this study ... -
The prediction of mortality from continuous noninvasive cardiovascular signals on standing: entropy was significant, but not the overall response profile
(2022)In this study, a novel approach is presented using principal component analysis and sample entropy (SampEn) for the analysis of continuous blood pressure (BP) data measured non-invasively during an active stand (AS) in ... -
Were Frailty Identification Criteria Created Equal? A Comparative Case Study on Continuous Non-Invasively Collected Neurocardiovascular Signals during an Active Standing Test in the Irish Longitudinal Study on Ageing (TILDA)
(2024)Background: In this observational study, we compared continuous physiological signals during an active standing test in adults aged 50 years and over, characterised as frail by three different criteria, using data from ...
