Abstract
Background: Patients in acute exacerbation of chronic heart failure represent an important health problem and economic burden that requires proper intervention and treat-ment.
Aim of Work: To investigate the validity of Inferior Vena Cava (IVC) dynamics as a noninvasive diagnostic monitoring tool in patients with acute exacerbation of heart failure.
Methods: Thirty patients with decompensated heart failure (NYHA class III-IV) 16 males and 14 females mean age 50±13 years were included, admitted to ICU, and had full echocar-diographic study including IVC dynamics: IVC diameter at end of expiration, at end inspiration, and collapse index (IVC-CI%) on admission, on days 5 and 10 of medical treatment. Also, ten volunteers were included as control group.
Results: After therapy, the IVC-CI% significantly increased on day 10 with mean 45.2±8.6% compared to IVC-CI% on day 5 with mean 27.7±8.6% compared to IVC-CI% on admis-sion with mean 11.7±4.79% (p-value <0.001).
FS% increased significantly after 5 days compared to day 1 with mean 24.13±3.6%, however, there was no significant changes between day 10 and 5 values (p values <0.001 and >0.05 respectively).
EF% increased statistically after 5 and 10 days of therapy compared to day 1 values: 25.7±5.3%, 34.2±5.6%, 20.6±3.6% with p-values <0.001 and <0.05 respectively.
Conclusion: IVC dynamics appears to be simple reliable noninvasive bedside tool in management and monitoring therapy of patients with acute decompensated heart failure.
