Abstract
Recently, many authors have been interested in using abdominal venous flow on ultrasound to predict kidney injury in patients after cardiac surgery. There have been no studies evaluating these indicators in patients with acute heart failure. The objective of our study was to characterize the inferior vena cava diameter and hepatic vein flow in patients with acute heart failure, and the ability to predict acute kidney injury in these patients. Prospective observational study included patients with acute heart failure treated at the Vietnam National Heart Institute, Bach Mai Hospital. The findings of the study revealed that among 94 individuals with acute heart failure, 51% were males, 47.9% had inferior vena cava diameter ≥ 21mm, and 72.3% with abnormal hepatic venous flow. The size of the inferior vena cava is correlated with acute kidney injury with OR 3.75, 95% CI: 1.43 – 9.79, whereas the correlation between hepatic venous flow and acute kidney injury is unclear. It is necessary to coordinate several indicators to make the most accurate clinical decisions.
