Incremental Value of right atrial (RA) strain over baseline model. RA reservoir strain, conduit strain, and booster strain added incremental prognostic value over clinical and cardiovascular magnetic resonance (CMR) factors for the prediction of all-cause mortality (A) and composite heart failure (HF) endpoint (B) with a significant improvement of Chi-square value. The baseline model included age, systolic blood pressure, New York Heart Association (NYHA) class, Log (N-terminal prohormone of brain natriuretic peptide), left ventricular (LV) ejection fraction (LVEF), LV end diastolic volume index, right ventricular (RV) ejection fraction (LVEF), left atrial (LA) end diastolic volume index, and late gadolinium enhancement (LGE)
