Introduction: Left ventricular diastolic dysfunction (LVDD) adversely impacts renal function, and E/e′ is a significant predictor of adverse kidney events under different clinical conditions. However, no studies have evaluated the association between LVDD and septic acute kidney injury (AKI) among patients with severe sepsis and septic shock. Methods: This multicenter retrospective study evaluated adult patients with severe sepsis or septic shock between January 1, 2013, and December 31, 2019, who underwent echocardiography within 24 hours after admission to an intensive care unit. Results: A total of 495 adult patients were enrolled in the study. LVDD grades II and III were associated with severe (stage 3) AKI ( p < 0.001, p for trend < 0.001). E/e′ and e′ were risk factors for septic AKI (OR, 1.155; 95% CI, 1.088–1.226, p < 0.001; and OR, 7.218; 95% CI, 2.942–17.712, p < 0.001, respectively) in the multivariate logistic regression analysis. The area under the receiver operating characteristic curve of E/e′ and e′ was 0.728 (95% CI, 0.680–0.777, p < 0.001) and 0.715 (95% CI, 0.665–0.764, p < 0.001), respectively. Conclusions: LVDD was associated with septic AKI, and E/e′ and e′ are useful predictors of septic AKI among patients with severe sepsis or septic shock. Trial registration The study was registered at the Chinese Clinical Trial Registry (Protocol No. ChiCTR2000033083).
