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).

Baseline left ventricular (LV) dysfunction is associated with subsequent risks of acute kidney injury (AKI) and mortality in patients with sepsis. This study investigated the therapeutic effects of continuous renal replacement therapy (CRRT) in hemodynamically unstable patients with severe sepsis and septic shock combined with LV dysfunction. In this multicenter retrospective study, severe sepsis and septic shock patients with LV dysfunction were classified into one of two groups according to the timing of CRRT: the early group (before AKI was detected) or the control group (patients with AKI). Patients from the control group received an accelerated strategy or a standard strategy of CRRT. The primary outcome was all-cause intensive care unit (ICU) mortality. Patients were weighted by stabilized inverse probability of treatment weights (sIPTW) to overcome differences in baseline characteristics. After sIPTW analysis, the ICU mortality was significantly lower in the early group than the control group (27.7% vs. 63.5%, p < 0.001). Weighted multivariable analysis showed that early CRRT initiation was a protective factor for the risk of ICU mortality (OR 0.149; 95% CI 0.051–0.434; p < 0.001). The ICU mortality was not different between the accelerated- and standard-strategy group (52.5% vs. 52.9%, p = 0.970). Early CRRT in the absence of AKI is suggested for hemodynamically unstable patients with severe sepsis and septic shock combined with LV dysfunction since it benefits survival outcomes.

Background: Baseline left ventricular (LV) dysfunction is associated with subsequent risks of acute kidney injury (AKI) and mortality in patients with sepsis. This study investigated the therapeutic effects of continuous renal replacement therapy (CRRT) in hemodynamically unstable patients with severe sepsis and septic shock combined with LV dysfunction.Methods: In this multicenter retrospective study, severe sepsis and septic shock patients with LV dysfunction were classified into one of two groups according to the timing of CRRT: the early group (before AKI was detected) or the control group (patients with AKI). All-cause intensive care unit (ICU) mortality and ICU stay were compared between the groups. Patients were weighted by stabilized inverse probability of treatment weights (sIPTW) to overcome differences in baseline characteristics.Results: After sIPTW analysis, the ICU mortality was significantly lower in the early group than the control group (25.9% vs 59.0%, p < 0.001). Weighted multivariable analysis showed that early CRRT initiation was a protective factor for the risk of ICU mortality. Early CRRT initiation significantly improved the ICU mortality compared to the control group (OR, 0.322; 95% CI, 0.125-0.834; p = 0.020).Conclusions: Early CRRT in the absence of AKI is suggested for hemodynamically unstable patients with severe sepsis and septic shock combined with LV dysfunction since it benefits survival outcomes.Trial registration: The study was preregistered in the Chinese Clinical Trial Registry (number, ChiCTR2000033083).

Background: Low birth weight (LBW) is one of the risk factors for coronary heart disease (CHD). The association of LBW and other risk factors with male patients with premature CHD has not been fully determined. This study aims to assess the association of LBW and other risk factors with the incidence of male patients with premature CHD.Methods We identified hospitalized male patients with premature CHD (CHD group) and healthy male subjects (control group) from January 2013 to December 2018. The differences of demographics, birth weight (BW) and other traditional risk factors were compared between the CHD group and the control group and logistic regression was used to estimate their effects on the risk of premature CHD.Results A total of 384 male subjects were enrolled in the study (183 in the CHD group vs 201 in the control group). There were significant differences in BW, smoking, diabetes and hyperlipidemia between the two groups (2.98±0.35 vs 3.37±0.39kg, P<0.001, 73.22% vs 27.36%, P<0.001, 8.74% vs 3.48%, P=0.033, 53.55% vs 37.31%, P=0.001) respectively. The risk of premature CHD increased significantly with the LBW (OR=4.530, 95% CI：1.331-15.412，P=0.016) and smoking (OR=6.748, 95% CI：4.258-10.693，P<0.001) respectively according to the multivariate logistic regression model. Conclusion LBW and smoking are independently and positively correlated with male patients with premature CHD. A history of LBW should be paid particularly attention in younger men for primordial prevention of premature CHD, especially away from tobacco.
