Portal Vein Pulsatility: A Valuable Approach for Monitoring Venous Congestion and Prognostic Evaluation in Acute Decompensated Heart Failure

Zusammenfassung:The severity of systemic congestion is associated with increased portal vein flow pulsatility (PVP). To determine the usefulness of PVP as a marker of decongestion and prognosis in acute decompensated heart failure (ADHF) patients. 105 patients, 60% of whom were men, were hospitalized with ADHF, and their PVP index (PVPI) was calculated (maximum velocity-minimum velocity/maximum velocity) × 100 on admission and before discharge, along with their EVEREST score, inferior vena cava diameter (IVC), NT-proBNP, serum sodium, and glomerular filtration rate. A PVPI ≥ 50% was defined as a marker of systemic congestion. After treatment with loop diuretics, a decrease in PVPI of >50% before discharge was considered a marker of decongestion The patients were classified into two groups (G): G1-PVPI decrease ≥ 50% (54 patients) and G2-PVPI decrease < 50% (51 patients). At discharge, compared to G2, G1 patients had lower mean PVPI (14.2 vs. 38.9; < 0.001), higher serum Na (138 vs. 132 mmol/L, = 0.03), and a higher number of patients with a significant (>30%) NT-proBNP decrease (42 vs. 27, = 0.007). PVPI correlated with IVC (r = 0.55, < 0.001), NT-proBNP (r = 0.21, = 0.04), and serum Na (r = -0.202, = 0.04). A total of 55% of patients had worsening renal failure (G1 63% vs. G2 48%, = 0.17). After 90 days, G2 patients had higher mortality (27.45% vs. 3.7 = 0.001) and rehospitalization (49.01% vs. 33.33%, < 0.001). In multivariate regression analysis, PVPI was an independent predictor of rehospitalization (OR 1.05, 95% CI 1.00-1.10, = 0.048). Portal vein flow pulsatility, a meaningful marker of persistent subclinical congestion, is related to short-term prognosis in ADHF patients.
