Figure 1: Correlation of plasma ET-1 levels with LAD in patients with mitral valve disease. r is Pearson’s correlation coefficient. ET-1: endothelin 1; LAD: left atrial dimension. From: Endothelin-1 is associated with dilatation of the left atrium and can be an independent predictor of atrial fibrillation after mitral valve surgery Interact CardioVasc Thorac Surg.

Figure 2: ROC curve for postoperative atrial fibrillation after mitral valve surgery, based on LAD and ET-1. Area under the curve: 0.77 (95% confidence interval: 0.66–0.88). ET-1: endothelin 1; LAD: left atrial dimension; ROC: receiver operating characteristics.
