Methods One hundred and twenty six patients with AECOPD were measured pulmonary artery systolic pressure (P ASP) by echocardiography. They were divided into 3 groups according to PASP:control group ?40 mrn Hg ) 45 cases, mild PH group (40-60 mrn Hg) 47 cases and mederate-severe PH group (〉60 mrn Hg ) 34 cases. Serum NT-Pro BNP,CRP,D-Dimer levels and arterial blood gas analysis were detected from all the selected patients. Results Serum NT-Pro BNP,PCO, ,CRP and D-Dimer in AECOPD with rnederate-severe PH group [NT-Pro BNP: (l 711. 15 ± 437.05) ng/L; PCO2 (47. 24± 8. 60) mrn Hg , CRP: (25.53 ± 1. 73) mgv/L, D-Dimer: (648.88 ± 618. 37) μg/L] were significantly higher than the control ones [NT-Pro BNP: (221. 78 ± 63.62) ng/L, PCO,: (40.04 ± 6.83) mmHg,CRP:C11. 51±2. 00) mg/L,D-Dimer: (302. 58±233. 44) μg/L] ( t = -4. 005, -3. 880, -3.094,-4.073, P〈0.05),while PO, [arterial partial pressure of oxygen:(59.43±16.49) mrn Hg ] were significantly lower than the control ones (71. 28±15. 16) mmHg (t = 3. 276, P 〈0.05). Serum NT-Pro BNP, PCO, in AECOPD with rnederate-severe PH group [NT-Pro BNP: (1711.15 ± 437.05) ng/L,PCO2 (47. 24±8. 60) mmHg] ,were significantly higher than the mild PH ones [NT-Pro BNP: (583. 77±213. 98) ng/L,PCO2 (40. 85±8. 96) rnm Hg j/ t = -3.069, -3. 442, P 〈0. 05), while PO2 (59.43 ± 16.49) ] mmHg were significantly lower than the mild PH group ones (66.81 ± 16.22) mrn Hg (t =2. 061, P〈0. 05). Serum CRP and the D-Dimer levels in mild PH group [CRP:(17. 55± 4.17) mg/L,D-Dimer:(501. 61±218. 71) μg/L] were significantly higher than the control ones [CRP: (11. 51±2. 00) mg/L;D-Dimer: (302. 58±233. 44) μg/L] ( t = -1. 452, -2. 551, P 〈 0.05). NT-Pro BNP was observered a significant positive linear relationship between PASP ( r =0.346, t =4. 11, P 〈0. 01) and PCO,( r =0. 336, t =3.97, P 〈0. 01). We also found that PCO, ,CRP,D-Dimer levels have a significant positive linear relationship between PASP ( r = 0. 389, t = 4.70, r = 0. 245, t = 2.81, r = 0.349, t =4. 15, P 〈0. 05) ,while PO2 was negatively correlated with PASP ( r = -0.262, t = -3.02, P 〈 0.05). Conclusions Serum NT-Pro BNP,CRP and D-Dimer levels are closely related to the PASP, and can be used as indicators to judge the severity of PH in of AECOPD patients.
