Risk stratification by combination of global CFR and stress perfusion CMR. A Risk stratification by combining stress perfusion CMR and global CFR (p < 0.001 for overall). B Annualized event rates in subgroups. A subgroup with ischemia and impaired CFR (CFR < 2.5) experienced a significantly higher annualized event rate of 8.0% compared with the other subgroups (with ischemia and no impaired CFR: event rate 5.6%, p = 0.012; with impaired CFR and no ischemia: event rate 5.1%, p = 0.002; and without ischemia or impaired CFR: event rate 2.1%, p < 0.001). The subgroup with ischemia and no impaired CFR and the subgroup with no ischemia and impaired CFR had comparable prognosis (p = 0.731), while both of these subgroups experienced worse prognosis (p < 0.001, respectively) than in the absence of ischemia and impaired CFR
