O6-3 - Hemodynamic Residual Congestion Assessed by Right Heart Catheterization Was Related to Poor Prognosis in Patients with Clinically Compensated Heart Failure

Abstract

Background: Residual clinical congestion is known to be associated with poor prognosis. However, the prognostic importance of hemodynamic congestion remains uncertain. Methods: Among patients who were admitted with acute decompensated heart failure, 51 patients underwent right heart catheterization (RHC) in clinically compensated status after conventional treatment. We defined hemodynamic residual congestion as PCWP >15 mmHg and investigated its prognostic importance. Results: During the mean follow up period of 437 ± 251 days, patients with relatively high PCWP (>15 mmHg, n = 27) were more likely to have experienced major adverse cardiac events (death, heart failure re-hospitalization, LVAD implantation) than those with lower PCWP (<15 mmHg, n = 24, 51.9% versus 12.5%, Log-rank test, P = .01, Figure). Conclusion: Hemodynamic residual pulmonary congestion as assessed by RHC was associated with poor prognosis in patients with heart failure even in clinically compensated status.
