Key result
In an experimental rat model, ventricular BNP mRNA expression was specifically upregulated in overt heart failure (359% of control in the left ventricle, P<0.001) but not in compensated heart failure.
Why the study?
Does overt heart failure specifically induce cardiac BNP mRNA expression compared to compensated heart failure in rats?

May refine natriuretic peptide use across HF stages; leaves open differential ANP/BNP regulation in human compensated versus overt failure.
Does overt heart failure specifically induce cardiac BNP mRNA expression compared to compensated heart failure in rats?
p-value: p=<0.001
Cardiac BNP mRNA expression is specifically induced in overt heart failure, suggesting its role as a marker for the transition from compensated to overt heart failure.
Langenickel et al. (2000) studied Experimental heart failure. Large aortocaval shunt (overt heart failure model) vs. Compensated heart failure models and controls was evaluated on Ventricular BNP mRNA expression (p=<0.001). In an experimental rat model, ventricular BNP mRNA expression was specifically upregulated in overt heart failure (359% of control in the left ventricle, P<0.001) but not in compensated heart failure.
