Diagnostic accuracy of noninvasive estimate of elevated filling pressure. Receiving operating characteristic (ROC) curves for global peak atrial longitudinal strain (PALS), left atrial (LA) volume indexed and mean E/Em ratio for prediction of pulmonary capillary wedge pressure ≥18 mmHg in patients with advanced systolic heart failure. (PALS, peak atrial longitudinal strain; LA, left atrial; E, early transmitral flow velocity; Em, early diastolic mitral annular velocity; AUC, area under the curve).
