Résumé en anglais

Objective To analyse the incidence and the impact on outcome of right ventricular failure (RVF) in patients with acute respiratory distress syndrome (ARDS). Patients and methods A total of 145 ARDS patients included in the previously published French Pulmonary Artery Catheter (PAC) study were randomly assigned to receive a PAC. All patients were ventilated according to a strategy aimed at limiting plateau pressure. The RVF was defined by the concomitant presence of: (1) a mean pulmonary artery pressure (MPAP) > 25 mmHg, (2) a central venous pressure (CVP) higher than pulmonary artery occlusion pressure (PAOP) and (3) a stroke volume index < 30 mL m−2. Results Right ventricular failure was present in 9.6% of patients. Mortality was 68% at day-90 with no difference between patients with RVF (RVF+) and without RVF (71 vs. 67%, respectively). SAPS II, PaO2/FiO2 and PaCO2 were similar in both groups. Tidal volume and I/E ratio were significantly higher in RVF+ (9.7 ± 2.8 vs. 8.6 ± 1.8 ml m−2 and 0.7 ± 0.5 vs. 0.5 ± 0.2). Plateau pressure tended to be higher in RVF+ (28 ± 6 vs. 25 ± 6 cmH2O, NS). In multivariate analysis, PaO2/FiO2, mean arterial pressure, arterial pH, SvO2, MPAP and presence of CVP > PAOP, but not RVF, were independently associated with day-90 mortality. Conclusion In this group of patients investigated early in the course of ARDS and ventilated according to a strategy aimed at limiting plateau pressure, the presence of RVF was about 10%. Unlike MPAP and the presence of CVP > PAOP, RVF at this early stage did not appear as an independent factor of mortality.
