Introduction There have been few studies on predictors of weaning failure from MV in patients with heart (HF). We sought to investigate the predictive value B-lines measured by lung ultrasound (LUS) risk mechanical ventilation (MV) and in-hospital outcomes. Methods This was a single-center, prospective observational study that included HF who were invasive MV. LUS performed immediate before ventilator weaning. A positive exam defined as observation two or more regions had three count located bilaterally thorax. The primary outcome early failure, re-intubation within 72 h. Results total 146 consecutive (mean age 70 years; 65.8% male) enrolled. median 10 correlated NT-pro-BNP level ( r 2 = 0.132, p < 0.001). Early significantly higher group (9 out 64, 14.1%) than negative (2 82, 2.4%) 0.011). rate during hospital stay 0.004), duration intensive care unit 0.010) greater group. (NPV) 97.6% for outcome. Conclusion can predict failure. Considering high NPV LUS, it may help guide decision due acute decompensated HF.
