Behavior of right atrial strain in high systolic pulmonary artery pressure

Aims Evaluate the ability of right atrial (RA) strain to predict systolic pulmonary artery pressure (SPAP). Methods and Results A total of 102 patients were prospectively enrolled. Conventional echocardiographic measures were performed. RA volume was calculated. Mean maximum right ventricle (RV) strain and lateral RA strain were obtained. Pearson's correlation test was used. A multivariate analysis was performed to compare SPAP with RA strain, RV strain, and baseline characteristics of the patients. RA strain was compared between patients with SPAP ≤ 37 mm Hg with those with SPAP > 37 mm Hg. A receiver operating characteristic (ROC) curve was constructed. A P
