The quest for meaningful outcomes
NICE-SUGAR: NEJM 2009 DECRA: NEJM 2011
Neurohormonal regulation is a complex biological process.
Neurohormonal modulation is a complex therapeutic intervention
β-blockade is a small component of modulatory therapy
The efficacy of β-blockade in chronic heart failure has been
determined in large RCTs.
The efficacy of β-blockade after ACS remains uncertain
The biological effects of β-blockade in inflammatory states are
complex, but tantalising based on animal and observational
Caution is required with neuroendocrine intervention in
critically ill patients.
A pragmatic RCT to test the effects of β-blockade on patient-
centred outcomes in sepsis is required.
