Using a ROC curve analysis, CFVR 2.14 was the best predictor of cardiac events and was considered as abnormal CFVR. Abnormal CFVR was associated with lower cardiac event-free survival (30 vs 80%, p\u2009&lt;\u20090.0001). During FU, 70% of women with reduced CFVR had cardiac events whereas only 20% with normal CFVR (p\u2009=\u20090.0001). At multivariate Cox analysis, smoke habitus (p\u2009=\u20090.003), metabolic syndrome (p\u2009=\u20090.01), and CFVR (p\u2009&lt;\u20090.0001) were significantly associated with cardiac events at
