Figure 4From: Left atrial longitudinal strain by speckle tracking echocardiography correlates well with left ventricular filling pressures in patients with heart failure 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).Back to article page
