[Influence of anemia on hemodynamic changes in patients with cirrhosis]. / Influence de l'anémie sur les modifications hémodynamiques des malades atteints de cirrhose.

OBJECTIVE: The aim of this retrospective study was to evaluate the systemic and splanchnic hemodynamic changes induced by anemia in patients with cirrhosis. METHOD: 148 patients (Child-Pugh A: 46 patients, Child-Pugh B: 64 patients and Child-Pugh C: 38 patients) were included in the study. Anemia was defined by a blood hemoglobin level < 12 g/dL. A systemic and splanchnic hemodynamic study was performed in all patients. RESULTS: A significant elevation of the hepatic venous pressure gradient was observed in Child-Pugh A patients with anemia but not in Child-Pugh B and C patients. In the 2 latter groups, cardiac index was significantly increased and systemic vascular resistance decreased in patients with anemia. CONCLUSION: Anemia may worsen the hemodynamic changes associated with cirrhosis.
