Observational study reveals distinct protein concentrations in lymph and edema fluids in congestive heart failure, indicating fluid shift dynamics depend on venous pressure.

Key Points

To evaluate how hydrostatic and colloid osmotic pressures influence excess lymph and edema fluid formation across diverse vascular beds in congestive heart failure.
Measured protein concentrations in plasma, regional lymph (thoracic duct, liver, small intestine), and edema fluid (pleural, peritoneal/ascitic, leg) in 42 patients with cardiac failure.
Evaluated differences in protein distributions between acute and chronic stages of heart failure.
In acute heart failure, thoracic duct lymph and ascitic fluid exhibited high protein concentrations, reaching 85% and 68% of plasma protein levels, respectively.
In chronic heart failure, thoracic duct lymph and ascitic fluid protein concentrations decreased to 46% and 40% of plasma protein due to dilution from extrahepatic lymph.
Pleural fluid (26% to 44% of plasma protein) and leg edema fluid (3% to 8% of plasma protein) maintained consistently low protein content across both acute and chronic stages.
