Key result
In patients with sinus rhythm, left atrial contractile function assessed by speckle tracking echocardiography accurately predicted PCWP ≥18 mm Hg (AUC 0.895), outperforming average E/E' ratio.

Does left atrial strain assessed by speckle tracking echocardiography predict invasively measured hemodynamic parameters in patients with cardiovascular diseases?
Effect estimate: AUC 0.895
Left atrial contractile function assessed by speckle tracking echocardiography accurately predicts elevated pulmonary capillary wedge pressure in patients with sinus rhythm.
Hewing et al. (2017) conducted an observational in Myocardial and valvular diseases (n=69). Left atrial strain assessed by speckle tracking echocardiography vs. Average E/E' ratio was evaluated on Prediction of PCWP ≥18 mm Hg (AUC 0.895). In patients with sinus rhythm, left atrial contractile function assessed by speckle tracking echocardiography accurately predicted PCWP ≥18 mm Hg (AUC 0.895), outperforming average E/E' ratio.
