Impact of coronary hyperemia on collateral flow correction of coronary microvascular resistance indices

Conclusion - We validated the calculation method for Pw-corrected MR in a Doppler-velocity derived population. In addition, we found a significant impact of hyperemic conditions on the measurement of Pw and the derivation of Pw-corrected HMR.PMID:38391315 | DOI:10.1152/ajpheart.00771.2023
