Why the study?

Does portal vein pulsatility ratio correlate with echocardiographic parameters of heart failure severity in inpatients with heart failure?

Key Points

This study aims to explore the relationship between portal vein pulsatility ratio and heart failure severity using noninvasive assessments.
Evaluated 87 inpatients with heart failure using duplex Doppler sonography of the heart, portal, and hepatic veins.
Compared measurements of liver and spleen dimensions and blood flow with echocardiographic data.
Patients with NYHA class III-IV showed reduced portal vein mean velocity and decreased pulsatility ratio (PR).
Significant positive correlation between PR and left ventricular shortening fraction (r=0.34, p<0.01) and ejection fraction (r=0.38, p<0.001).
Significant negative correlations found between PR and various cardiac measurements indicating worsening heart function.

Structured PICO

Does portal vein pulsatility ratio correlate with echocardiographic parameters of heart failure severity in inpatients with heart failure?

Population

87 inpatients with heart failure, mean age 64+/-12 years.

Intervention

Duplex Doppler sonography of the heart and portal and hepatic veins to assess portal vein pulsatility ratio (PR)

Outcome

Relationships between measurements of liver and spleen dimensions and blood flow in portal and hepatic veins and echocardiographic datasurrogate

Portal vein pulsatility ratio assessed by Doppler sonography correlates significantly with echocardiographic indices of heart failure severity and can serve as a reliable adjunctive sign of heart failure.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Portal vein PR was associated with LVEF and RV size in HF inpatients; leaves open its incremental value over echocardiography for monitoring or prognosis.
