Agreement Between Invasive Wire-Based and Angiography-Based Vessel Fractional Flow Reserve Assessment on Intermediate Coronary Stenoses

Frontiers in Cardiovascular Medicine, 2021
Background: Angiography-based functional assessment of coronary stenoses emerges as a novel approach to assess coronary physiology. We sought to investigate the agreement between invasive coronary wire-based fractional flow reserve (FFR), resting full ...

Impact of coronary revascularization on clinical outcomes in vessels with discordant results of fractional flow reserve and resting full-cycle ratio. [PDF]

Heart Vessels
Abstract Fractional flow reserve (FFR) is an invasive standard, and resting full-cycle ratio (RFR), a non-hyperemic pressure ratio, is an alternative to FFR for evaluating the functional severity of coronary stenosis. However, the prognostic impact of coronary revascularization in vessels with discordant results of FFR and non ...

P5619Comparison of different resting physiological indices: are diastolic pressure ratio and resting full-cycle ratio equal?

European Heart Journal, 2019
Abstract Background Previous reports showed all diastolic resting indexes tested were virtually identical to the instantaneous wave-free ratio (iFR). Although RFR has been also reported to be diagnostically equivalent to iFR, no comparisons have been reported about the prevalence and characteristics ...

Numerical investigation for failure load and contact stress beneath RC square footing resting on cohesionless soil

Case Studies in Construction Materials, 2021
The contact pressure distribution below, reinforced concrete footing, does not solely depend on the type of soil, but also on the change of the footing stiffness after cracking.

Comparison of quantitative flow ratio with instantaneous wave‐free ratio and resting full‐cycle ratio during daily routine in the catheterization laboratory

Catheterization and Cardiovascular Interventions, 2023
AbstractBackgroundQuantitative flow ratio (QFR) is a novel, software‐based method to evaluate the physiology of coronary lesions. The aim of this study was to compare QFR with the established invasive measurements of coronary blood flow using instantaneous wave‐free ratio (iFR) or resting full‐cycle ratio (RFR) in daily cathlab routine.Methods102 ...

The Menstrual Cycle Alters Resting-State Cortical Activity: A Magnetoencephalography Study [PDF]

, 2021
Resting-state neural oscillations are used as biomarkers for functional diseases such as dementia, epilepsy, and stroke. However, accurate interpretation of clinical outcomes requires the identification and minimisation of potential confounding factors ...

Impact of menstrual cycle on resting and postprandial metabolism in recreationally active, eumenorrheic females [PDF]

, 2023
The impact of the menstrual cycle on resting and postprandial metabolism is unclear. In this study, five eumenorrheic women had resting energy expenditure (REE) and substrate utilization measured at rest and after a mixed meal during three phases of the ...
