Values are presented as mean±SD or median (25th–75th percentile). APV: average peak flow velocity; CFVR: coronary flow velocity reserve; IRA: infarct-related artery; MR: microvascular resistance.
baseline, laboratory and procedural covariates as listed in Tabel 1. Subsequent multivariate analysis was performed using a multivariate linear regression model with adjustments for these variables to identify the association of glucose levels with microvascular function parameters, which are presented as standardised coefficients to facilitate comparison. A p-value below the two- sided α-level of 0.05 was considered statistically significant.
