Abstract
Objective
The purpose of this study was to examine whether routine blood tests can be useful in predicting mortality in COPD patients.
Methods
Eligible studies were found through a search conducted in the PubMed and Embase databases, the Cochrane Library, and the Web of Knowledge. Twelve studies were included for the meta-analysis of five biochemical markers. Pooled odds ratios (ORs), matching 95% confidence intervals (CIs), and p-values for each of the biochemical markers were calculated using the random effect model.
Results
The following four examined biochemical markers were shown to be associated with mortality in patients suffering from COPD: anemia (OR=2.62, 95% CI: 1.60; 4.29, p=0.01), hypoalbuminemia (OR=2.90, 95% CI: 1.56; 5.40, p=0.0008), elevated NT-proBNP (OR=7.54, 95% CI: 4.04; 14.10, p<0.00001), and elevated cardiac troponin T (OR=3.10, 95% CI: 1.11; 8.25, p=0.03). hs-CRP was not found to be associated with increased mortality.
Conclusion
In this study, we found that anemia, hypoalbuminemia, elevated NT-proBNP, and elevated cardiac troponin T were associated with increased mortality in patients suffering from COPD.
