Relationship between LV systolic function and diastolic function by E/e′ in patients with HFpEF (n = 37). LV GLS correlates to diastolic function (left) while ejection fraction (EF) does not (right). If excluding the patient with E/e′ 34 appearing as an outlier in the figure, the results remain unchanged; GLS correlates to E/e′ (R = 0.42, P = 0.01) while EF does not (R = −0.03, P = 0.88). E, peak early diastolic filling velocity; e′, early diastolic mitral annular velocity (septal).
