Right atrial strain: what does it tell us about cardiac function and prognosis?

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main source(s): New Zealand National Heart Foundation Background The role speckle tracking echocardiography has been expanding thanks to its utility in detecting subtle changes cardiac function, and prognostic value(1). Right atrial (RA) strain shown promise prognostication amongst patients with pulmonary hypertension heart failure. It is associated RA size, RV function IVC size. However, clinical application remain under investigation (2–5). We sought evaluate the associations right both invasive non-invasive measure association failure hospitalisations death across a heterogeneous cohort. Methods A single-centre retrospective analysis data from 225 consecutive (age 72 ±11.6 years old; male 56%) catheterization (RHC) TTE. Data regarding unplanned date were recorded. Statistical was performed using SAS 15.1 assess between prespecified echo haemodynamic measures left prognosis defined by death. Results Over median follow up 28±16 months, there 59 events. following systolic : TAPSE; pressure, strain, PAPi, RVSWI, FAC, LAVi, PA coupling (TAPSE/systolic PAP), LVEF, index, diastolic (E/e’) p value <0.05. Increasing size lower values R strain. Despite impaired prognosis, HR 2.94 (1.14 – 7.60), did not appear be independently 0.98 (0.95–1.0) P = 0.0676. Conclusions may useful tool help us function. despite being linked which strongly our
