Why the study?
The application of a simple blood test to predict prognosis in acute heart failure patients is not well established.

NLR may support risk stratification in AHF; leaves open whether it improves decision-making or outcomes.
Does an elevated neutrophil-lymphocyte ratio predict in-hospital and long-term mortality in patients with acute heart failure?
Elevated neutrophil-lymphocyte ratio is a simple, inexpensive, and independent predictor of in-hospital and long-term mortality in patients with acute heart failure.
