Delirium is a common and major complication subsequent to cardiac surgery. Despite scientific efforts, there are no parameters which reliably predict postoperative delirium. In delirium pathology, natriuretic peptides (NPs) interfere with the blood–brain barrier and thus promote delirium. A recent study by Saller et al. , which used the Biomedica NT-proCNP ELISA, found a positive correlation between delirium and preoperative plasma levels of ANP and serum levels NT-proCNP. Both ANP and NT-proCNP predicted delirium, but did not correlate with postoperative survival or long-term cognitive decline.

Sepsis-associated encephalopathy (SAE) has significant impact on the neurocognitive outcome of sepsis survivors. Biomarkers of brain injury and inflammation could help monitor encephalopathy in patients with sepsis.
Levels of NT-proCNP, a protein which is released during systemic inflammation, are highly elevated in both the plasma and CSF of sepsis patients with SAE. Since NT-proCNP levels in CSF and plasma NT-proCNP are highly correlated, plasma NT-proCNP might be a useful proxy biomarker to predict the emergence of SAE during the early phase of sepsis and detect neurological impairment at the later stages of the disease.
Plasma NT-proCNP measurement might be superior to S100B and NSE in SAE.
