Venous excess ultrasound score and acute kidney injury in patients with acute coronary syndrome Academic Article in Scopus uri icon

abstract

  • Aims: Systemic venous congestion is associated with an increased risk of acute kidney injury (AKI) in critically ill patients. Venous Excess Ultrasound Score (VExUS) has been proposed as a non-invasive score to assess systemic venous congestion. We aimed to evaluate the association between VExUS and AKI in patients with acute coronary syndrome (ACS). Methods and results: This is a prospective study including patients with the diagnosis of ACS (both ST elevation and non-ST elevation ACS). VExUS was performed during the first 24 h of hospital stay. Patients were classified according to the presence of systemic congestion (VExUS 0/¿1). The primary objective of the study was to determine the occurrence of AKI, defined by KDIGO criteria. A total of 77 patients were included. After ultrasound assessment, 31 (40.2%) patients were categorized as VExUS ¿1. VExUS ¿1 was more frequently found in inferior vs. anterior myocardial infarction/non-ST-segment elevation acute myocardial infarction (48.3 vs. 25.8 and 22.5%, P = 0.031). At each increasing degree of VExUS, a higher proportion of patients developed AKI: VExUS = 0 (10.8%), VExUS = 1 (23.8%), VExUS = 2 (75.0%), and VExUS = 3 (100%; P < 0.001). A significant association between VExUS ¿1 and AKI was found [odds ratio (OR): 6.75, 95% confidence interval (CI): 2.21-23.7, P = 0.001]. After multivariable analysis, only VExUS ¿1 (OR: 6.15; 95% CI: 1.26-29.94, P = 0.02) remained significantly associated with AKI. Conclusion: In patients hospitalized with ACS, VExUS is associated with the occurrence of AKI. Further studies are needed to clarify the role of VExUS assessment in patients with ACS. © 2023 The Author(s). Published by Oxford University Press on behalf of the European Society of Cardiology.
