Heart Failure Duration Combined with Left Atrial Dimension Predicts Super-Response and Long-Term Prognosis in Patients with Cardiac Resynchronization Therapy Implantation

Figure 1

(a) ROC curve for LAD (red line) and combination of HF duration and LAD (green line) in predicting super-response; (b) ROC curve for HF duration (red line) and combination of HF duration and LAD (green line) in predicting super-response. ROC: receiver operator characteristic; HF: heart failure; LAD: left atrial dimension; AUC: the area under the curve.

(a) AUC (0.899 versus 0.775, Z = 2.487, P = 0.013)
(b) AUC (0.899 versus 0.789, Z = 2.207, P = 0.027)
