Phase-contrast cine-magnetic resonance imaging (PC-CMR) of the coronary sinus (CS) is a promising approach for quantifying coronary sinus flow (CSF) and global coronary flow reserve (G-CFR). We evaluated the prognostic value of G-CFR using PC-CMR in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS).Methods and Results:The study prospectively enrolled 116 NSTE-ACS patients who underwent uncomplicated urgent PCI within 48 h of symptom onset. Post-PCI (median, 20 days) PC-CMR images of the CS were acquired to assess absolute CSF at rest and during maximum hyperemia. The association of G-CFR with major adverse cardiac events (cardiac death, nonfatal myocardial infarction, late revascularization, or hospitalization for congestive heart failure) was investigated. Rest and maximal hyperemic CSF and corrected G-CFR were 1.27 [interquartile range, 0.79-1.73] mL/min/g, 2.95 [2.02-3.84] mL/min/g, and 2.42 [1.69-3.34], respectively. At a median follow-up of 17 months, cardiac event-free survival was significantly worse in patients with a corrected G-CFR &lt;2.33 (log-rank χ 2 =19.5, P&lt;0.001). Cox proportional-hazards analysis showed that corrected G-CFR (hazard ratio, 0.434, 95% CI, 0.270-0.699, P&lt;0.001) and NT-pro BNP at admission (hazard ratio, 1.0001, 95% CI, 1.0000-1.0001, P=0.007) were independent predictors of adverse cardiac events during follow-up.
