Fig. 1From: Blunted heart rate recovery is associated with coronary artery spasm in patients with suspected vasospastic anginaComparison of areas under the curve (AUCs) of logistic regression models. On the receiving operator characteristic analysis, blunted HRR together with max HR significantly improved the goodness-of-fit and discriminability of Model 1 (log-likelihood difference = 10.58; p < 0.001; C-index difference = 2.64%; p = 0.007). Model 1: age + gender + current smoking; Model 3: Model 1 + max heart rate + blunted heart rate recoveryBack to article page
