Lymphocytopenia is associated with mortality in acute heart failure (AHF), and portal congestion has been suggested to play a role in leukocyte distribution. The associations between lymphocytopenia and ultrasound surrogates for portal congestion have never been studied. We aimed to characterize the determinants of lymphocytopenia, explore the associations between lymphocytopenia and portal congestion, and explore the relationships between lymphocytopenia and outcomes in AHF. ⋯ In AHF, lymphocytopenia is associated with ultrasound surrogates for portal congestion and right ventricular dysfunction. Whether these associations depict a potent pathophysiologic pathway or whether they only reflect a more advanced disease remains uncertain.
