Abstract
<p>Introduction: Advanced heart failure (HF) patients often have high pulmonary vascular resistance (PVR) which prevents candidacy to heart transplantation. Atrial myocardial deformation analysis assessed by speckle tracking echocardiography is a research imaging technique that provides information about all the components of atrial function: reservoir, conduit and booster pump.We aimed to evaluate atrial myocardial deformation analysis as predictors of invasively measured PVR in advanced HF patients.</p> <p>Methods: Retrospective, observational study that included 15 advanced HF patients that performed echocardiography and hemodynamic assessment in the same week. Atrial myocardial deformation was evaluated by speckle tracking imaging from acquired apical 4 chambers and two chambers cine loops, using EchoPAC workstation. Strain and strain rate addressing reservoir (S), conduit (E) and booster pump (A) functions were determined. Invasive hemodynamic pressure curves were reviewed, and relevant hemodynamic data was collected.Scatter plots and Pearson correlations were computed to examine the intercorrelations of the variables.</p> <p>Results: PVR was significantly correlated with strain-S (4C) r(12)= -0,706, p=0,01, strain-S (2C) r(10)= - 0,767, p= 0,01, strain-E (2C) r(9)=-0,754, p=0,019, strain-A (4C) r(10)=-0,772, p=0,009, strain rate -A (4C) r(11)= 0,616, p=0,044. A regression model to predict PVR including strain-A (4C) was statistically significant F (1,8)= 11,764, p= 0,009. The adjusted R2 value was 0,55, meaning that 55% of the variance in PVR was explained by the model.</p> <p>Conclusion: All the components of atrial function – reservoir, conduct and booster pump – evaluated by atrial myocardial deformation speckle tracking analysis are correlated with invasively assessed PVR in advanced HF patients.</p>
