Figure 4. Four groups stratified by impairment of hyperemic coronary sinus flow (h‐CSF) and global coronary flow reserve (g‐CFR).

Figure 4

Group ① is 100 of 523 (19.1%) patients with concordantly impaired h‐CSF and g‐CFR; blue. Group ② is 73 of 523 (14.0%) patients with impaired h‐CSF and preserved g‐CFR; green. Group ③ is 66 of 523 (12.6%) patients with preserved h‐CSF and impaired g‐CFR; yellow. Group ④ is 284 of 523 (54.3%) patients with concordantly preserved h‐CSF and g‐CFR; red. A, The distribution of 523 patients with acute myocardial infarction stratified by 4 groups with concordant or discordant impairment of h‐CSF (<1.6) and g‐CFR (<1.7). B, Frequency of major adverse cardiac events (MACEs) stratified by 4 groups with concordant or discordant impairment of h‐CSF (<1.6) and g‐CFR (<1.7). The patients with concordantly impaired h‐CSF and g‐CFR showed significantly higher frequency of MACEs. C, Kaplan‐Meier curve for event‐free survival stratified by 4 groups with concordant or discordant impairment of h‐CSF (<1.6) and g‐CFR (<1.7). Event‐free survival was significantly worse in patients with concordantly impaired h‐CSF and g‐CFR.
