BACKGROUND: The prognostic impact of pneumonia and signs of systemic inflammation in patients with acute decompensated heart failure (ADHF) has not been fully elucidated yet. The aim of the present study was thus to investigate the association of pneumonia and the inflammation surrogate C-reactive protein with all-cause mortality in patients admitted for ADHF.

METHODS: We analysed data of 1939 patients admitted for ADHF. Patients were dichotomised according to the presence or absence of pneumonia. The primary endpoint of all-cause mortality was determined by death registry linkage.

RESULTS: In total, 412 (21.2%) patients had concomitant pneumonia. Median C-reactive protein levels were higher in patients with compared to patients without pneumonia (24.9 versus 9.8 mg/l, respectively; P<0.001). All-cause mortality was significantly higher in patients with pneumonia ( P<0.001). In adjusted Cox regression models, pneumonia as well as C-reactive protein were independently associated with in-hospital mortality. Only C-reactive protein remained as independent predictor for long-term mortality.

CONCLUSION: Pneumonia is relatively common in ADHF and a predictor for in-hospital mortality. However, inflammation in general seems to be more important than pneumonia itself for long-term prognosis. Compared to community-acquired pneumonia studies, C-reactive protein levels were rather low and therefore pneumonia might be over-diagnosed in ADHF patients.
