BACKGROUND: In @entity1 with @entity120 ( @entity120 ), right ventricular pressure overload eventually causes @entity712 ( @entity712 ), leading to a poor prognosis. Right atrial (RA) overload and @entity409 occur in @entity1 with @entity120 -complicated @entity712 . OBJECTIVES: We evaluated RA function using @entity6475 ( @entity6475 ) by two-dimensional speckle tracking echocardiography (2D-STE) and investigated the association between @entity6475 and the severity of @entity712 in @entity1 with @entity120 ( @entity120 ) noninvasively. METHODS: We performed 2D-STE in 56 @entity120 @entity1 and 20 normal control subjects. The peak global @entity6475 and peak global RA longitudinal strain rate (RALSR) were analyzed by 2D-STE. Simultaneous right heart catheterization was performed to determine the right atrial pressure (RAP) and cardiac index (CI). RESULTS: Peak global @entity6475 (34.6      14.1 vs. 58.3      9.9  %, p  <  0.0001) and peak global RALSR (2.5      1.3 vs. 3.1      1.2  s(-1), p  <  0.0001) were significantly lower in @entity120 @entity1 compared with normal controls. There was a significant negative correlation between peak global @entity6475 and RAP (r  =  -0.8037, p  <  0.0001). There was a significant positive correlation between peak global @entity6475 and CI (r  =  0.8179, p  <  0.0001). Peak global RALSR was also correlated with RAP (r  =  -0.7308, p  <  0.0001) and CI (r  =  0.7596, p  <  0.0001). CONCLUSIONS: @entity6475 and RALSR by 2D-STE were useful for noninvasive evaluation of @entity409 and the severity of @entity712 in @entity1 with @entity120 .
