Table 4. An admission BUN concentration above 28mg/dL is associated with long-term mortality regardless of admission diagnosis [pneumonia (n = 533), pulmonary embolism (n = 153), acute coronary syndrome (ACS; n = 1909), sepsis (n = 544) and heart failure (AHF, n = 611)].
Hazard ratios (HR) were obtained by Cox regression analysis.
| admission diagnosis | HR | 95%CI | p-value |
|---|---|---|---|
| overall cohort | 3.74 | 3.29–4.25 | <0.001 |
| sepsis | 1.77 | 1.33–2.36 | <0.001 |
| AHF | 1.76 | 1.33–2.32 | <0.001 |
| pneumonia | 1.59 | 1.21–2.10 | 0.002 |
| pulmonary embolism | 5.8 | 3.27–10.26 | <0.001 |
| ACS | 5.41 | 4.25–6.90 | <0.001 |
