RESUMEN
Objective To investigate the application value of hs-CRP and BNP detection in COPD patients with pulmonary heart disease.Methods From January 2016 to January 2018,80 patients with COPD in the Fifth People＇s Hospital of Datong were selected.Forty-two COPD patients complicated with pulmonary heart disease were selected as COPD and cor pulmonale group,38 COPD patients without pulmonary heart disease were selected as COPD group,and 30 healthy volunteers were selected as control group.The differences of hs-CRP and BNP levels were compared,and the diagnostic value of hs-CRP and BNP for COPD combined with pulmonary heart disease was analyzed.Results There were statistically significant differences in hs-CRP[(72.5 ± 20.4) mg/L vs.(37.5 ± 9.8) mg/L vs.(3.7 ± 1.2)mg/L],BNP[(362.8 ± 86.9) ng/L vs.(125.9 ± 34.8) ng/L vs.(28.5 ± 9.9)ng/L] among the COPD and cor pulmonale group,COPD group and control group (F=9.245,14.668,all P<0.05).The hs-CRP and BNP levels in the COPD and cor pulmonale group were significantly higher than those in the other two groups(t=19.294,11.576,21.385,9.258,9.258,all P<0.05),which of the COPD group were significantly higher than those of the control group (t=8.912,12.567,all P<0.05).The best boundary value of BNP in diagnosis of COPD with cor pulmonale was 261.8ng/L,and its diagnostic sensitivity and specificity were 96.2% and 85.4% , respectively,the area under the line was 0.834,which were all higher than those of hs-CRP.With the increase of cardiac function,the levels of hs-CRP[(38.5 ± 10.3) mg/L vs.(51.4 ± 14.8) mg/L vs.(75.1 ± 21.5) mg/L vs.(93.7 ± 31.8) mg/L],BNP[(142.8 ± 56.5) ng/L vs.(285.9 ± 94.8) ng/L vs.(352.5 ± 118.2) ng/L vs. (478.5 ± 130.3)ng/L] increased,the differences were statistically significant (F=13.577,16.776,all P<0.05). There were significant correlation between hs-CRP,BNP levels and COPD patients complicated with cor pulmonale (r=0.675,0.766,all P<0.05).Conclusion hs-CRP and BNP have high diagnostic potency for COPD patients combined with cor pulmonale,and are positively correlated with cardiac function classification.
