Methods This was a prospective observational cohort study of 42 patients conducted in the intensive care unit of a tertiary care university hospital. BNP was measured and transthoracic echocardiography was performed within 48 hours of the onset of acute lung injury. The left ventricular systolic and diastolic function right ventricular systolic function and cardiac output were assessed. BNP was compared in patients with and without right ventricular dilatation as well as in survivors versus nonsurvivors. Results BNP was elevated in mechanically ventilated patients with acute lung injury median 420 pg ml 25-75 interquartile range 156-728 pg ml . There was no difference between patients with and without right ventricular dilatation 420 pg ml 119-858 pg ml vs. 387 pg ml 156-725 pg ml p . There was no difference in BNP levels between the patients who died and those who survived at 30 days 420 pg ml 120-728 pg ml vs. 385 pg ml 159-1070 pg ml p . Conclusions In patients with acute lung injury the level of BNP is increased but there is no .
