Impact of Microvascular Resistance on Coronary Hemodynamic Diagnostic Indices: A Multiscale Simulation Study

Abstract Purpose Coronary diagnostic indices—fractional flow reserve (FFR) and coronary flow reserve (CFR)—disagree in up to 30% of cases, complicating diagnosis and revascularization decisions. Microvascular health likely drives this discordance, but its isolated effect is chall...
