Key result
A mathematical model of coronary blood flow predicts that the presence, rather than severity, of microvascular disease deleteriously affects coronary flow and fractional flow reserve.
Why the study?
Coronary stenosis treatment decisions rely on invasive fractional flow reserve measurements, motivating non-invasive methods that use mathematical models of coronary hemodynamic physiology.
Comparison

Model suggests microvascular disease presence may confound FFR regardless of severity; leaves open need for prospective clinical validation.
An in silico mathematical model demonstrates that both epicardial stenosis (focal and diffuse) and the presence of microvascular disease significantly influence coronary flow and FFR estimation.
Joseph et al. (2022) studied Coronary stenosis and microvascular disease. Mathematical model of coronary vasculature was evaluated on Fractional flow reserve estimation. A mathematical model of coronary blood flow predicts that the presence, rather than severity, of microvascular disease deleteriously affects coronary flow and fractional flow reserve.
