Does the BUN/Cr ratio predict mortality in patients with acute decompensated heart failure and acute kidney injury?
Elevated BUN/Cr ratio combined with AKI is a useful marker for increased mortality risk in patients with acute decompensated heart failure.
The combination of AKI and elevated BUN/Cr, but not BUN or creatinine individually, is linked with an increased risk of mortality in ADHF patients, suggesting that the BUN/Cr is useful for risk stratification of AKI.
Takaya et al. (Thu,) studied this question.
