Key result
Plasma alpha-hANP concentrations were significantly higher in patients with severe lung injury (188.0 +/- 94.6 pg/ml) compared to normal subjects (31.7 +/- 12.0 pg/ml, p<0.001).

Are plasma alpha-hANP concentrations elevated in patients with acute lung injury compared to normal subjects?
Absolute Event Rate: 188% vs 31.7%
p-value: p=<0.001
Plasma alpha-hANP is significantly elevated in acute lung injury, correlating with diuresis and fluid balance, suggesting an adaptive mechanism to reduce fluid retention and pulmonary hypertension.
Mitaka et al. (1992) conducted an observational in Acute lung injury (n=15). Severe lung injury vs. Normal subjects was evaluated on Plasma alpha-hANP concentration (p=<0.001). Plasma alpha-hANP concentrations were significantly higher in patients with severe lung injury (188.0 +/- 94.6 pg/ml) compared to normal subjects (31.7 +/- 12.0 pg/ml, p<0.001).
