![]() ![]() The BNP levels were significantly higher in the non-survivor group than in the survivor group ( P<0.001). The BNP levels of the high-risk group (PSI classes IV and V) were significantly higher than those of the low-risk group (PSI classes I-III) ( P<0.001). RESULTS: The BNP levels increased with CAP severity ( r=0.782, P<0.001). BNP levels for survivor and non-survivor groups were compared, and a receiver operating characteristic (ROC) curve analysis was performed on the BNP levels versus PSI. The correlation between the indexes and PSI was investigated. METHODS: For 202 patients with CAP admitted to the emergency department, BNP levels, cardiac load indexes, inflammatory indexes including C-reactive protein (CRP), white blood cell count (WBC), and PSI were detected. The present study aimed to evaluate the role of B-type natriuretic peptide (BNP) in predicting the severity of CAP. BACKGROUND: Although pneumonia severity index (PSI) is widely used to evaluate the severity of community-acquired pneumonia (CAP), the calculation of PSI is very complicated. ![]()
