Fractional-Order Windkessel Boundary Conditions in a One-Dimensional Blood Flow Model for Fractional Flow Reserve (FFR) Estimation

Fractal and Fractional, 2023
Recent studies have demonstrated the benefits of using fractional derivatives to simulate a blood pressure profile. In this work we propose to combine a one-dimensional model of coronary blood flow with fractional-order Windkessel boundary conditions ...

Microvascular resistance reserve: insights into discordant resting and hyperemic epicardial coronary physiology [PDF]

Frontiers in Cardiovascular Medicine
IntroductionDiscordance between resting and hyperemic epicardial physiology is commonbut mechanistically unclear. Microvascular resistance reserve (MRR), a novelindex of vasodilatory capacity, may provide insight.
