Table 4 Categorization and identification of the best cut-off points of each variable independently associated with the development of inducible myocardial ischemia: the ROC curve analyses

From: Echocardiographic markers of inducible myocardial ischemia at baseline evaluation preparatory to exercise stress echocardiography

Variables Cut-off point AUC [95 % CI] Sensitivity Specificity
Peak S’ (cm/sec) 10.0 0.69 [0.60–0.78] 72 % 60 %
LV CESS (Kdynes/cm2) 124.0 0.67 [0.56–0.78] 63 % 60 %
LASF (Kdynes) 14.0 0.61 [0.51–0.72] 63 % 60 %
