Key words: heart failure, portal flow, Dopplerography.

There is little information about portal hemodynamic in heart failure. The aim of this work was to evaluate the portal flow in patients with heart failure (HF).

Materials and Methods: We studied 35 patients with HF (11 had I-II and 24 had III-IV NYHA class HF) and 60 patients without HF, chronic or acute pulmonary and/or liver diseases or gastrointestinal disorders. Portal flow was studied using PW Dopplerography and Sonography. Examinations were performed preprandially. We measured the maximal, minimal and mean velocity of the flow (cm/sec) and portal vein diameter (in mm).

Results: The Doppler flow parameters were lower in the HF group. The portal flow velocity was lower in patients with III-IV NYHA fcl, than with I-II NYHA fcl. The latter did not differ significantly from the control group parameters.

Conclusion: The Doppler estimated maximal, minimal and mean velocity of portal flow is reduced in patients with pronounced stages of HF, but is not changed significantly in patients with mild HF.
