Figure 4

Receiver operating characteristic curve analysis for diagnosing left anterior descending artery (LAD) stenosis. (a) Compared with the peak systolic strain alone, the integrated analysis of the three parameters from using the regression function significantly improved the accuracy in diagnosing single-vessel LAD stenosis (P = 0.040). (b) The integrated analysis did not improve the accuracy in diagnosing multivessel LAD stenosis (P = 0.832).
