Comparison of change in markers of coronary microcirculatory function with remote ischemic preconditioning and sham. The relative change in IMR_calc (A) and CFR (B) induced by RIPC was significantly different to the change due to sham treatment. Individual filled symbols represent relative change in measurement with RIPC/sham in each patient, with negative and positive values indicative of reductions and increases with treatment, respectively. Open symbols and bars represent mean±SD. CFR indicates coronary flow reserve; IMR_calc, calculated index of microcirculatory resistance; RIPC, remote ischemic preconditioning.
