Implication
May refine mortality risk assessment in shock; leaves open utility for excluding cardiogenic shock or guiding therapy.
Structured PICO
Does NT-proBNP testing predict hemodynamics and ICU mortality in critically ill patients with shock?
P
Population
49 consecutive patients in four different ICUs with shock of various types and with an indication for pulmonary artery catheter placement
I
Intervention
NT-proBNP testing at the time of pulmonary artery catheter placement
O
Outcome
Correlation with pulmonary artery catheter findings and ICU mortalityhard clinical
In ICU patients with shock, NT-proBNP levels do not correlate with filling pressures but strongly predict ICU mortality and can help exclude cardiogenic shock.
