However, the anaerobic threshold, both as an absolute (p = 0.009) and as a % of predicted value (p = 0.047), was significantly lower during follow-up. In adult CF patients with stable, mild-to-moderate disease, a peak VO2 may be preserved for several years. However, even in these patients, deconditioning is present. In adult CF patients with stable, mild-to-moderate disease, a peak VO2 may be preserved for several years. However, even in these patients, deconditioning is present. Acute respiratory distress syndrome (ARDS) is a life-threatening chest disease associated with a poor outcome and increased mortality. It may lead to pulmonary hypertension and, eventually, right ventricular failure. These changes can be investigated by transthoracic echocardiography (TTE) which is considered a non-invasive and cost-effective modality. We studied the role of right ventricular function in the prediction of the severity and mortality in ARDS. In this observational study, 94 patients suffering from ARDS were subjected to TTE to evaluate the parameters of right ventricular function by measuring tricuspid annular plane systolic excursion (TAPSE), right ventricular fractional area change (RV-FAC), myocardial performance index (Tei index), and systolic pulmonary artery pressure (SPAP) to assess their relation to the severity and mortality in ARDS. TAPSE, SPAP, Tei index, and RV-FAC showed significant differences between survivors and non-survivors after 30 days (all p < 0.001). An increased length of intensive care unit stay was significantly correlated with TAPSE, Tei index, and RV-FAC (p = 0.002' 0.007' and 0.013, respectively). Meanwhile, the length of mechanical ventilation days was significantly correlated with the Tei index only (p < 0.001). Multivariate regression analysis found that TAPSE and the Tei index were in
