Microvascular characteristics

Equation

v b

v b  = MBF ⋅ T c

v e

v e  = MBF ⋅ (T − T c )

v d

v d  = MBF ⋅ T

PS

\( PS=\frac{MBF\cdot \left(T-{T}_c\right)}{T_e} \)

E

\( E=1- \exp \left(-\frac{PS}{MPF}\right) \)

MPF

MPF = MBF ⋅ (1 − hct)

  1. Microvascular characteristics were calculated by incorporating the fitted parameters of the distributed parameter model into the following relationships (see reference [4]). Myocardial plasma flow (MPF) was used to calculate extravascular-extracellular space (ve), distribution volume (vd), permeability surface area product (PS) and extraction fraction (E) and myocardial blood flow (MBF) to calculate intravascular space (vb). Hematocrit: hct.
