ABSTRACT
Objective To investigate the Laboratory diagnostic value of COPD with congestive cardiac failure .The clinical signif‐icance on the combined detection of the serum B‐type natriuretic peptide(BNP) ,high sensitive C reactive protein (hs‐CRP) ,and he‐moglobin(Hb) in COPD with congestive cardiac failure .Methods The serum levels of BNP ,hs‐CRP and Hb in 205 patients with different etiological factors and grades(according to the pulmonary function test Ⅰ - Ⅳ) and 100 healthy controls were determined . The sensitivity and specificity of 3 parameters were evaluated .Results The levels of BNP ,hs‐CRP ,and Hb in different grades of COPD had statistical significance(P0 .05) .The sensitivity of combined detection was 90 .2% in early COPD diagnosis ,which was higher significantly than that of the individual detection (P<0 .05) .Conclusion The significant clinical significance on the combined detection of the serum BNP ,hs‐CRP and Hb provides reference support in the diagnosis of early COPD .
