Elevated mean central venous pressure is associated with an increased risk of acute kidney injury (AKI) in critically ill patients with a broad spectrum of cardiovascular diseases. Nowadays, it is possible to perform a non-invasive assessment of systemic venous congestion using the Venous Excess Ultrasound Score (VExUS) which may enable early identification of patients with increased risk of adverse renal outcomes. This study aimed to evaluate the association between venous congestion assessed with VExUS and the incidence of AKI in patients with acute coronary syndrome (ACS). Venous congestion assessment using VExUS was performed in consecutive patients with ACS. Linear regression analysis was used to determine the variables associated with the highest measured serum creatinine (sCr) during hospitalization and the admission sCr. In addition, a multivariable logistic regression analysis was performed for assessing the independent risk factors for AKI, which was defined according to the KDIGO criteria. A total of 77 patients hospitalized with ACS were prospectively enrolled in this study. Nineteen (25.6%) patients developed AKI. Baseline chronic kidney disease, Killip-Kimball >II on admission, GRACE score, admission NTproBNP values, and VExUS were significantly higher in the AKI-group than in the non-AKI group. Baseline chronic kidney disease, admission NT-proBNP values, and VExUS were independent risk factors associated with the highest measured sCr and the admission sCr. In multivariable logistic regression analysis, the risk of AKI was significantly associated with baseline chronic kidney disease, admission NT-proBNP values, and VExUS. Baseline chronic kidney disease, admission NT-proBNP values, and VExUS were significant independent predictors of AKI in patients with ACS.
