摘要: Abstract Background Accurate non-invasive estimation of right atrial pressure (RAP) is essential to assess volume status and optimize therapy in heart failure (HF). This study aimed evaluate the utility reservoir strain (RASr) assessed by speckle-tracking echocardiography identify elevated RAP HF compare diagnostic performance with estimated employing inferior vena cava size collapsibility (RAPIVC), addition RA area. Method Association between RASr invasive (RAPInvasive) was examined 103 subjects that underwent standard analysis directly followed catheterization. The discriminatory ability RAPInvasive > 7 mmHg evaluated compared RAPIVC Results demonstrated association RAPInvasive (β = −0.41, p 7 mmHg (AUC = 0.78; 95% CI 0.68–0.87; Conclusions demonstrates good relatively stronger when conventional measures. may be useful as a novel noninvasive estimate management.
